MII51001-1.8
Introduction
The MAX® II family of instant-on, non-volatile CPLDs is based on a 0.18-µm, 6-layermetal-flash process, with densities from 240 to 2,210 logic elements (LEs) (128 to 2,210
equivalent macrocells) and non-volatile storage of 8 Kbits. MAX II devices offer high
I/O counts, fast performance, and reliable fitting versus other CPLD architectures.
Featuring MultiVolt core, a user flash memory (UFM) block, and enhanced in-system
programmability (ISP), MAX II devices are designed to reduce cost and power while
providing programmable solutions for applications such as bus bridging, I/O
expansion, power-on reset (POR) and sequencing control, and device configuration
control.

MAX II and MAX IIG devices are available in three speed grades: –3, –4, and –5, with
–3 being the fastest. Similarly, MAX IIZ devices are available in two speed grades: –6,
–7, with –6 being faster. These speed grades represent the overall relative
performance, not any specific timing parameter. For propagation delay timing
numbers within each speed grade and density, refer to the DC and Switching
Characteristics chapter in the MAX II Device Handbook.

Features
1–3
MAX II devices are available in space-saving FineLine BGA, Micro FineLine BGA, and
thin quad flat pack (TQFP) packages (refer to Table 1–3 and 1–3). MAX II devices
support vertical migration within the same package (for example, you can migrate
between the EPM570, EPM1270, and EPM2210 devices in the 256-pin FineLine BGA
package). Vertical migration means that you can migrate to devices whose dedicated
pins and JTAG pins are the same and power pins are subsets or supersets for a given
package across device densities. The largest density in any package has the highest
number of power pins; you must lay out for the largest planned density in a package
to provide the necessary power pins for migration. For I/O pin migration across
densities, cross reference the available I/O pins using the device pin-outs for all
planned densities of a given package type to identify which I/O pins can be migrated.
The Quartus® II software can automatically cross-reference and place all pins for you
when given a device migration list.

MAX II devices have an internal linear voltage regulator which supports external
supply voltages of 3.3 V or 2.5 V, regulating the supply down to the internal operating
voltage of 1.8 V. MAX IIG and MAX IIZ devices only accept 1.8 V as the external
supply voltage. MAX IIZ devices are pin-compatible with MAX IIG devices in the
100-pin Micro FineLine BGA and 256-pin Micro FineLine BGA packages. Except for
external supply voltage requirements, MAX II and MAX II G devices have identical
pin-outs and timing specifications. Table 1–5 shows the external supply voltages
supported by the MAX II family.

Functional Description
MAX® II devices contain a two-dimensional row- and column-based architecture to
implement custom logic. Row and column interconnects provide signal interconnects
between the logic array blocks (LABs).
The logic array consists of LABs, with 10 logic elements (LEs) in each LAB. An LE is a
small unit of logic providing efficient implementation of user logic functions. LABs
are grouped into rows and columns across the device. The MultiTrack interconnect
provides fast granular timing delays between LABs. The fast routing between LEs
provides minimum timing delay for added levels of logic versus globally routed
interconnect structures.
The MAX II device I/O pins are fed by I/O elements (IOE) located at the ends of LAB
rows and columns around the periphery of the device. Each IOE contains a
bidirectional I/O buffer with several advanced features. I/O pins support Schmitt
trigger inputs and various single-ended standards, such as 66-MHz, 32-bit PCI, and
LVTTL.
MAX II devices provide a global clock network. The global clock network consists of
four global clock lines that drive throughout the entire device, providing clocks for all
resources within the device. The global clock lines can also be used for control signals
such as clear, preset, or output enable.

Each MAX II device contains a flash memory block within its floorplan. On the
EPM240 device, this block is located on the left side of the device. On the EPM570,
EPM1270, and EPM2210 devices, the flash memory block is located on the bottom-left
area of the device. The majority of this flash memory storage is partitioned as the
dedicated configuration flash memory (CFM) block. The CFM block provides the nonvolatile storage for all of the SRAM configuration information. The CFM
automatically downloads and configures the logic and I/O at power-up, providing
instant-on operation.
f
For more information about configuration upon power-up, refer to the Hot Socketing
and Power-On Reset in MAX II Devices chapter in the MAX II Device Handbook.
A portion of the flash memory within the MAX II device is partitioned into a small
block for user data. This user flash memory (UFM) block provides 8,192 bits of
general-purpose user storage. The UFM provides programmable port connections to
the logic array for reading and writing. There are three LAB rows adjacent to this
block, with column numbers varying by device.
Table 2–1 shows the number of LAB rows and columns in each device, as well as the
number of LAB rows and columns adjacent to the flash memory area in the EPM570,
EPM1270, and EPM2210 devices. The long LAB rows are full LAB rows that extend
from one side of row I/O blocks to the other. The short LAB rows are adjacent to the
UFM block; their length is shown as width in LAB columns.

Each LAB consists of 10 LEs, LE carry chains, LAB control signals, a local interconnect,
a look-up table (LUT) chain, and register chain connection lines. There are 26 possible
unique inputs into an LAB, with an additional 10 local feedback input lines fed by LE
outputs in the same LAB. The local interconnect transfers signals between LEs in the
same LAB. LUT chain connections transfer the output of one LE’s LUT to the adjacent
LE for fast sequential LUT connections within the same LAB. Register chain
connections transfer the output of one LE’s register to the adjacent LE’s register
within an LAB. The Quartus® II software places associated logic within an LAB or
adjacent LABs, allowing the use of local, LUT chain, and register chain connections
for performance and area efficiency. Figure 2–3 shows the MAX II LAB.

LAB Interconnects
The LAB local interconnect can drive LEs within the same LAB. The LAB local
interconnect is driven by column and row interconnects and LE outputs within the
same LAB. Neighboring LABs, from the left and right, can also drive an LAB’s local
interconnect through the DirectLink connection. The DirectLink connection feature
minimizes the use of row and column interconnects, providing higher performance
and flexibility. Each LE can drive 30 other LEs through fast local and DirectLink
interconnects. Figure 2–4 shows the DirectLink connection.

LAB Control Signals
Each LAB contains dedicated logic for driving control signals to its LEs. The control
signals include two clocks, two clock enables, two asynchronous clears, a
synchronous clear, an asynchronous preset/load, a synchronous load, and
add/subtract control signals, providing a maximum of 10 control signals at a time.
Although synchronous load and clear signals are generally used when implementing
counters, they can also be used with other functions.
Each LAB can use two clocks and two clock enable signals. Each LAB’s clock and
clock enable signals are linked. For example, any LE in a particular LAB using the
labclk1 signal also uses labclkena1. If the LAB uses both the rising and falling
edges of a clock, it also uses both LAB-wide clock signals. Deasserting the clock
enable signal turns off the LAB-wide clock.
Each LAB can use two asynchronous clear signals and an asynchronous load/preset
signal. By default, the Quartus II software uses a NOT gate push-back technique to
achieve preset. If you disable the NOT gate push-back option or assign a given register
to power-up high using the Quartus II software, the preset is then achieved using the
asynchronous load signal with asynchronous load data input tied high.
With the LAB-wide addnsub control signal, a single LE can implement a one-bit adder
and subtractor. This saves LE resources and improves performance for logic functions
such as correlators and signed multipliers that alternate between addition and
subtraction depending on data.
The LAB column clocks [3..0], driven by the global clock network, and LAB local
interconnect generate the LAB-wide control signals. The MultiTrack interconnect
structure drives the LAB local interconnect for non-global control signal generation.
The MultiTrack interconnect’s inherent low skew allows clock and control signal
distribution in addition to data. Figure 2–5 shows the LAB control signal generation
circuit.

Logic Elements
The smallest unit of logic in the MAX II architecture, the LE, is compact and provides
advanced features with efficient logic utilization. Each LE contains a four-input LUT,
which is a function generator that can implement any function of four variables. In
addition, each LE contains a programmable register and carry chain with carry-select
capability. A single LE also supports dynamic single-bit addition or subtraction mode
selectable by an LAB-wide control signal. Each LE drives all types of interconnects:
local, row, column, LUT chain, register chain, and DirectLink interconnects. See
Figure 2–6.

Each LE’s programmable register can be configured for D, T, JK, or SR operation. Each
register has data, true asynchronous load data, clock, clock enable, clear, and
asynchronous load/preset inputs. Global signals, general-purpose I/O pins, or any
LE can drive the register’s clock and clear control signals. Either general-purpose I/O
pins or LEs can drive the clock enable, preset, asynchronous load, and asynchronous
data. The asynchronous load data input comes from the data3 input of the LE. For
combinational functions, the LUT output bypasses the register and drives directly to
the LE outputs.
Each LE has three outputs that drive the local, row, and column routing resources. The
LUT or register output can drive these three outputs independently. Two LE outputs
drive column or row and DirectLink routing connections and one drives local
interconnect resources. This allows the LUT to drive one output while the register
drives another output. This register packing feature improves device utilization
because the device can use the register and the LUT for unrelated functions. Another
special packing mode allows the register output to feed back into the LUT of the same
LE so that the register is packed with its own fan-out LUT. This provides another
mechanism for improved fitting. The LE can also drive out registered and
unregistered versions of the LUT output.

Chapter 2: MAX II Architecture
Logic Elements
LUT Chain and Register Chain
In addition to the three general routing outputs, the LEs within an LAB have LUT
chain and register chain outputs. LUT chain connections allow LUTs within the same
LAB to cascade together for wide input functions. Register chain outputs allow
registers within the same LAB to cascade together. The register chain output allows an
LAB to use LUTs for a single combinational function and the registers to be used for
an unrelated shift register implementation. These resources speed up connections
between LABs while saving local interconnect resources. Refer to “MultiTrack
Interconnect” on page 2–12 for more information about LUT chain and register chain
connections.
addnsub Signal
The LE’s dynamic adder/subtractor feature saves logic resources by using one set of
LEs to implement both an adder and a subtractor. This feature is controlled by the
LAB-wide control signal addnsub. The addnsub signal sets the LAB to perform either
A + B or A – B. The LUT computes addition; subtraction is computed by adding the
two’s complement of the intended subtractor. The LAB-wide signal converts to two’s
complement by inverting the B bits within the LAB and setting carry-in to 1, which
adds one to the least significant bit (LSB). The LSB of an adder/subtractor must be
placed in the first LE of the LAB, where the LAB-wide addnsub signal automatically
sets the carry-in to 1. The Quartus II Compiler automatically places and uses the
adder/subtractor feature when using adder/subtractor parameterized functions.
LE Operating Modes
The MAX II LE can operate in one of the following modes:
■
“Normal Mode”
■
“Dynamic Arithmetic Mode”
Each mode uses LE resources differently. In each mode, eight available inputs to the
LE, the four data inputs from the LAB local interconnect, carry-in0 and carryin1 from the previous LE, the LAB carry-in from the previous carry-chain LAB, and
the register chain connection are directed to different destinations to implement the
desired logic function. LAB-wide signals provide clock, asynchronous clear,
asynchronous preset/load, synchronous clear, synchronous load, and clock enable
control for the register. These LAB-wide signals are available in all LE modes. The
addnsub control signal is allowed in arithmetic mode.
The Quartus II software, in conjunction with parameterized functions such as library
of parameterized modules (LPM) functions, automatically chooses the appropriate
mode for common functions such as counters, adders, subtractors, and arithmetic
functions.

Normal Mode
The normal mode is suitable for general logic applications and combinational
functions. In normal mode, four data inputs from the LAB local interconnect are
inputs to a four-input LUT (see Figure 2–7). The Quartus II Compiler automatically
selects the carry-in or the data3 signal as one of the inputs to the LUT. Each LE can use
LUT chain connections to drive its combinational output directly to the next LE in the
LAB. Asynchronous load data for the register comes from the data3 input of the LE.
LEs in normal mode support packed registers.

Note to Figure 2–7:
(1) This signal is only allowed in normal mode if the LE is at the end of an adder/subtractor chain.
Dynamic Arithmetic Mode
The dynamic arithmetic mode is ideal for implementing adders, counters,
accumulators, wide parity functions, and comparators. An LE in dynamic arithmetic
mode uses four 2-input LUTs configurable as a dynamic adder/subtractor. The first
two 2-input LUTs compute two summations based on a possible carry-in of 1 or 0; the
other two LUTs generate carry outputs for the two chains of the carry-select circuitry.
As shown in Figure 2–8, the LAB carry-in signal selects either the carry-in0 or
carry-in1 chain. The selected chain’s logic level in turn determines which parallel sum
is generated as a combinational or registered output. For example, when
implementing an adder, the sum output is the selection of two possible calculated
sums:
data1 + data2 + carry in0
or
data1 + data2 + carry-in1

MAX II Device Handbook
2–10
Chapter 2: MAX II Architecture
Logic Elements
The other two LUTs use the data1 and data2 signals to generate two possible carry-out
signals: one for a carry of 1 and the other for a carry of 0. The carry-in0 signal acts
as the carry-select for the carry-out0 output and carry-in1 acts as the carryselect for the carry-out1 output. LEs in arithmetic mode can drive out registered
and unregistered versions of the LUT output.
The dynamic arithmetic mode also offers clock enable, counter enable, synchronous
up/down control, synchronous clear, synchronous load, and dynamic
adder/subtractor options. The LAB local interconnect data inputs generate the
counter enable and synchronous up/down control signals. The synchronous clear
and synchronous load options are LAB-wide signals that affect all registers in the
LAB. The Quartus II software automatically places any registers that are not used by
the counter into other LABs. The addnsub LAB-wide signal controls whether the LE
acts as an adder or subtractor.

Carry-Select Chain
The carry-select chain provides a very fast carry-select function between LEs in
dynamic arithmetic mode. The carry-select chain uses the redundant carry calculation
to increase the speed of carry functions. The LE is configured to calculate outputs for a
possible carry-in of 0 and carry-in of 1 in parallel. The carry-in0 and carry-in1
signals from a lower-order bit feed forward into the higher-order bit via the parallel
carry chain and feed into both the LUT and the next portion of the carry chain. Carryselect chains can begin in any LE within an LAB.
MAX II Device Handbook
© October 2008 Altera Corporation
Chapter 2: MAX II Architecture
Logic Elements
2–11
The speed advantage of the carry-select chain is in the parallel precomputation of
carry chains. Since the LAB carry-in selects the precomputed carry chain, not every LE
is in the critical path. Only the propagation delays between LAB carry-in generation
(LE 5 and LE 10) are now part of the critical path. This feature allows the MAX II
architecture to implement high-speed counters, adders, multipliers, parity functions,
and comparators of arbitrary width.
Figure 2–9 shows the carry-select circuitry in an LAB for a 10-bit full adder. One
portion of the LUT generates the sum of two bits using the input signals and the
appropriate carry-in bit; the sum is routed to the output of the LE. The register can be
bypassed for simple adders or used for accumulator functions. Another portion of the
LUT generates carry-out bits. An LAB-wide carry-in bit selects which chain is used for
the addition of given inputs. The carry-in signal for each chain, carry-in0 or
carry-in1, selects the carry-out to carry forward to the carry-in signal of the nexthigher-order bit. The final carry-out signal is routed to an LE, where it is fed to local,
row, or column interconnects.

Chapter 2: MAX II Architecture
MultiTrack Interconnect
The Quartus II software automatically creates carry chain logic during design
processing, or you can create it manually during design entry. Parameterized
functions such as LPM functions automatically take advantage of carry chains for the
appropriate functions. The Quartus II software creates carry chains longer than 10 LEs
by linking adjacent LABs within the same row together automatically. A carry chain
can extend horizontally up to one full LAB row, but does not extend between LAB
rows.
Clear and Preset Logic Control
LAB-wide signals control the logic for the register’s clear and preset signals. The LE
directly supports an asynchronous clear and preset function. The register preset is
achieved through the asynchronous load of a logic high. MAX II devices support
simultaneous preset/asynchronous load and clear signals. An asynchronous clear
signal takes precedence if both signals are asserted simultaneously. Each LAB
supports up to two clears and one preset signal.
In addition to the clear and preset ports, MAX II devices provide a chip-wide reset pin
(DEV_CLRn) that resets all registers in the device. An option set before compilation in
the Quartus II software controls this pin. This chip-wide reset overrides all other
control signals and uses its own dedicated routing resources (that is, it does not use
any of the four global resources). Driving this signal low before or during power-up
prevents user mode from releasing clears within the design. This allows you to control
when clear is released on a device that has just been powered-up. If not set for its chipwide reset function, the DEV_CLRn pin is a regular I/O pin.
By default, all registers in MAX II devices are set to power-up low. However, this
power-up state can be set to high on individual registers during design entry using
the Quartus II software.
MultiTrack Interconnect
In the MAX II architecture, connections between LEs, the UFM, and device I/O pins
are provided by the MultiTrack interconnect structure. The MultiTrack interconnect
consists of continuous, performance-optimized routing lines used for inter- and intradesign block connectivity. The Quartus II Compiler automatically places critical
design paths on faster interconnects to improve design performance.
The MultiTrack interconnect consists of row and column interconnects that span fixed
distances. A routing structure with fixed length resources for all devices allows
predictable and short delays between logic levels instead of large delays associated
with global or long routing lines. Dedicated row interconnects route signals to and
from LABs within the same row. These row resources include:
■
DirectLink interconnects between LABs
■
R4 interconnects traversing four LABs to the right or left
The DirectLink interconnect allows an LAB to drive into the local interconnect of its
left and right neighbors. The DirectLink interconnect provides fast communication
between adjacent LABs and/or blocks without using row interconnect resources.
MAX II Device Handbook

Chapter 2: MAX II Architecture
MultiTrack Interconnect
2–13
The R4 interconnects span four LABs and are used for fast row connections in a fourLAB region. Every LAB has its own set of R4 interconnects to drive either left or right.
Figure 2–10 shows R4 interconnect connections from an LAB. R4 interconnects can
drive and be driven by row IOEs. For LAB interfacing, a primary LAB or horizontal
LAB neighbor can drive a given R4 interconnect. For R4 interconnects that drive to the
right, the primary LAB and right neighbor can drive on to the interconnect. For R4
interconnects that drive to the left, the primary LAB and its left neighbor can drive on
to the interconnect. R4 interconnects can drive other R4 interconnects to extend the
range of LABs they can drive. R4 interconnects can also drive C4 interconnects for
connections from one row to another.

Notes to Figure 2–10:

(2) This pattern is repeated for every LAB in the LAB row.
The column interconnect operates similarly to the row interconnect. Each column of
LABs is served by a dedicated column interconnect, which vertically routes signals to
and from LABs and row and column IOEs. These column resources include:
■
LUT chain interconnects within an LAB
■
Register chain interconnects within an LAB
■
C4 interconnects traversing a distance of four LABs in an up and down direction
MAX II devices include an enhanced interconnect structure within LABs for routing
LE output to LE input connections faster using LUT chain connections and register
chain connections. The LUT chain connection allows the combinational output of an
LE to directly drive the fast input of the LE right below it, bypassing the local
interconnect. These resources can be used as a high-speed connection for wide fan-in

functions from LE 1 to LE 10 in the same LAB. The register chain connection allows
the register output of one LE to connect directly to the register input of the next LE in
the LAB for fast shift registers. The Quartus II Compiler automatically takes
advantage of these resources to improve utilization and performance. Figure 2–11
shows the LUT chain and register chain interconnects.

The C4 interconnects span four LABs up or down from a source LAB. Every LAB has
its own set of C4 interconnects to drive either up or down. Figure 2–12 shows the C4
interconnect connections from an LAB in a column. The C4 interconnects can drive
and be driven by column and row IOEs. For LAB interconnection, a primary LAB or
its vertical LAB neighbor can drive a given C4 interconnect. C4 interconnects can
drive each other to extend their range as well as drive row interconnects for columnto-column connections.

Global Signals
Each MAX II device has four dual-purpose dedicated clock pins (GCLK[3..0], two
pins on the left side and two pins on the right side) that drive the global clock network
for clocking, as shown in Figure 2–13. These four pins can also be used as generalpurpose I/O if they are not used to drive the global clock network.
The four global clock lines in the global clock network drive throughout the entire
device. The global clock network can provide clocks for all resources within the
device including LEs, LAB local interconnect, IOEs, and the UFM block. The global
clock lines can also be used for global control signals, such as clock enables,
synchronous or asynchronous clears, presets, output enables, or protocol control
signals such as TRDY and IRDY for PCI. Internal logic can drive the global clock
network for internally-generated global clocks and control signals. Figure 2–13 shows
the various sources that drive the global clock network.

The global clock network drives to individual LAB column signals, LAB column

Unused global clocks or control signals in a LAB column are turned off at the LAB
column clock buffers shown in Figure 2–14. The LAB column clocks [3..0] are
multiplexed down to two LAB clock signals and one LAB clear signal. Other control
signal types route from the global clock network into the LAB local interconnect. See
“LAB Control Signals” on page 2–5 for more information.

User Flash Memory Block
MAX II devices feature a single UFM block, which can be used like a serial EEPROM
for storing non-volatile information up to 8,192 bits. The UFM block connects to the
logic array through the MultiTrack interconnect, allowing any LE to interface to the
UFM block. Figure 2–15 shows the UFM block and interface signals. The logic array is
used to create customer interface or protocol logic to interface the UFM block data
outside of the device. The UFM block offers the following features:

There are 512 locations with 9-bit addressing ranging from 000h to 1FFh. Sector 0
address space is 000h to 0FFh and Sector 1 address space is from 100h to 1FFh. The
data width is up to 16 bits of data. The Quartus II software automatically creates logic
to accommodate smaller read or program data widths. Erasure of the UFM involves
individual sector erasing (that is, one erase of sector 0 and one erase of sector 1 is
required to erase the entire UFM block). Since sector erase is required before a
program or write, having two sectors enables a sector size of data to be left untouched
while the other sector is erased and programmed with new data.

User Flash Memory Block
Internal Oscillator
As shown in Figure 2–15, the dedicated circuitry within the UFM block contains an
oscillator. The dedicated circuitry uses this internally for its read and program
operations. This oscillator's divide by 4 output can drive out of the UFM block as a
logic interface clock source or for general-purpose logic clocking. The typical OSC
output signal frequency ranges from 3.3 to 5.5 MHz, and its exact frequency of
operation is not programmable.
Program, Erase, and Busy Signals
The UFM block’s dedicated circuitry automatically generates the necessary internal
program and erase algorithm once the PROGRAM or ERASE input signals have been
asserted. The PROGRAM or ERASE signal must be asserted until the busy signal
deasserts, indicating the UFM internal program or erase operation has completed. The
UFM block also supports JTAG as the interface for programming and/or reading.
f
For more information about programming and erasing the UFM block, refer to the
Using User Flash Memory in MAX II Devices chapter in the MAX II Device Handbook.
Auto-Increment Addressing
The UFM block supports standard read or stream read operations. The stream read is
supported with an auto-increment address feature. Deasserting the ARSHIFT signal
while clocking the ARCLK signal increments the address register value to read
consecutive locations from the UFM array.
Serial Interface
The UFM block supports a serial interface with serial address and data signals. The
internal shift registers within the UFM block for address and data are 9 bits and 16 bits
wide, respectively. The Quartus II software automatically generates interface logic in
LEs for a parallel address and data interface to the UFM block. Other standard
protocol interfaces such as SPI are also automatically generated in LE logic by the
Quartus II software.
f
For more information about the UFM interface signals and the Quartus II LE-based
alternate interfaces, refer to the Using User Flash Memory in MAX II Devices chapter in
the MAX II Device Handbook.
UFM Block to Logic Array Interface
The UFM block is a small partition of the flash memory that contains the CFM block,
as shown in Figure 2–1 and Figure 2–2. The UFM block for the EPM240 device is
located on the left side of the device adjacent to the left most LAB column. The UFM
block for the EPM570, EPM1270, and EPM2210 devices is located at the bottom left of
the device. The UFM input and output signals interface to all types of interconnects
(R4 interconnect, C4 interconnect, and DirectLink interconnect to/from adjacent LAB
rows). The UFM signals can also be driven from global clocks, GCLK[3..0]. The
interface region for the EPM240 device is shown in Figure 2–16. The interface regions
for EPM570, EPM1270, and EPM2210 devices are shown in Figure 2–17.

MultiVolt Core
The MAX II architecture supports the MultiVolt core feature, which allows MAX II
devices to support multiple VCC levels on the VCCINT supply. An internal linear voltage
regulator provides the necessary 1.8-V internal voltage supply to the device. The
voltage regulator supports 3.3-V or 2.5-V supplies on its inputs to supply the 1.8-V
internal voltage to the device, as shown in Figure 2–18. The voltage regulator is not
guaranteed for voltages that are between the maximum recommended 2.5-V
operating voltage and the minimum recommended 3.3-V operating voltage.
The MAX IIG and MAX IIZ devices use external 1.8-V supply. The 1.8-V VCC external
supply powers the device core directly.

MAX II device IOEs contain a bidirectional I/O buffer. Figure 2–19 shows the MAX II

bidirectional I/O buffers. The Quartus II software automatically attempts to place
registers in the adjacent LAB with fast I/O connection to achieve the fastest possible
clock-to-output and registered output enable timing. For input registers, the
Quartus II software automatically routes the register to guarantee zero hold time.
You can set timing assignments in the Quartus II software to achieve desired I/O
timing.
Fast I/O Connection
A dedicated fast I/O connection from the adjacent LAB to the IOEs within an I/O
block provides faster output delays for clock-to-output and tPD propagation delays.
This connection exists for data output signals, not output enable signals or input
signals. Figure 2–20, Figure 2–21, and Figure 2–22 illustrate the fast I/O connection.

Each I/O bank has dedicated VCCIO pins that determine the voltage standard support
in that bank. A single device can support 1.5-V, 1.8-V, 2.5-V, and 3.3-V interfaces; each
individual bank can support a different standard. Each I/O bank can support
multiple standards with the same VCCIO for input and output pins. For example, when
VCCIO is 3.3 V, Bank 3 can support LVTTL, LVCMOS, and 3.3-V PCI. VCCIO powers both
the input and output buffers in MAX II devices.
The JTAG pins for MAX II devices are dedicated pins that cannot be used as regular
I/O pins. The pins TMS, TDI, TDO, and TCK support all the I/O standards shown in
Table 2–4 on page 2–27 except for PCI. These pins reside in Bank 1 for all MAX II
devices and their I/O standard support is controlled by the VCCIO setting for Bank 1.
PCI Compliance
The MAX II EPM1270 and EPM2210 devices are compliant with PCI applications as
well as all 3.3-V electrical specifications in the PCI Local Bus Specification Revision 2.2.
These devices are also large enough to support PCI intellectual property (IP) cores.

specifications.

Schmitt Trigger
The input buffer for each MAX II device I/O pin has an optional Schmitt trigger
setting for the 3.3-V and 2.5-V standards. The Schmitt trigger allows input buffers to
respond to slow input edge rates with a fast output edge rate. Most importantly,
Schmitt triggers provide hysteresis on the input buffer, preventing slow-rising noisy
input signals from ringing or oscillating on the input signal driven into the logic array.
This provides system noise tolerance on MAX II inputs, but adds a small, nominal
input delay.
The JTAG input pins (TMS, TCK, and TDI) have Schmitt trigger buffers that are always
enabled.
1
The TCK input is susceptible to high pulse glitches when the input signal fall time is
greater than 200 ns for all I/O standards.
Output Enable Signals
Each MAX II IOE output buffer supports output enable signals for tri-state control.
The output enable signal can originate from the GCLK[3..0] global signals or from
the MultiTrack interconnect. The MultiTrack interconnect routes output enable signals
and allows for a unique output enable for each output or bidirectional pin.
MAX II devices also provide a chip-wide output enable pin (DEV_OE) to control the
output enable for every output pin in the design. An option set before compilation in
the Quartus II software controls this pin. This chip-wide output enable uses its own
routing resources and does not use any of the four global resources. If this option is
turned on, all outputs on the chip operate normally when DEV_OE is asserted. When
the pin is deasserted, all outputs are tri-stated. If this option is turned off, the DEV_OE
pin is disabled when the device operates in user mode and is available as a user I/O
pin.
Programmable Drive Strength
The output buffer for each MAX II device I/O pin has two levels of programmable
drive strength control for each of the LVTTL and LVCMOS I/O standards.
Programmable drive strength provides system noise reduction control for high
performance I/O designs. Although a separate slew-rate control feature exists, using
the lower drive strength setting provides signal slew-rate control to reduce system
noise and signal overshoot without the large delay adder associated with the
slew-rate control feature. Table 2–6 shows the possible settings for the I/O standards
with drive strength control. The Quartus II software uses the maximum current
strength as the default setting. The PCI I/O standard is always set at 20 mA with no
alternate setting.

(1) The IOH current strength numbers shown are for a condition of a VOUT = VOH minimum, where the VOH minimum
is specified by the I/O standard. The IOL current strength numbers shown are for a condition of a VOUT = VOL
maximum, where the VOL maximum is specified by the I/O standard. For 2.5-V LVTTL/LVCMOS, the IOH
condition is VOUT = 1.7 V and the IOL condition is VOUT = 0.7 V.
Slew-Rate Control
The output buffer for each MAX II device I/O pin has a programmable output slewrate control that can be configured for low noise or high-speed performance. A faster
slew rate provides high-speed transitions for high-performance systems. However,
these fast transitions may introduce noise transients into the system. A slow slew rate
reduces system noise, but adds a nominal output delay to rising and falling edges.
The lower the voltage standard (for example, 1.8-V LVTTL) the larger the output
delay when slow slew is enabled. Each I/O pin has an individual slew-rate control,
allowing the designer to specify the slew rate on a pin-by-pin basis. The slew-rate
control affects both the rising and falling edges.
Open-Drain Output
MAX II devices provide an optional open-drain (equivalent to open-collector) output
for each I/O pin. This open-drain output enables the device to provide system-level
control signals (for example, interrupt and write enable signals) that can be asserted
by any of several devices. This output can also provide an additional wired-OR plane.
Programmable Ground Pins
Each unused I/O pin on MAX II devices can be used as an additional ground pin.
This programmable ground feature does not require the use of the associated LEs in
the device. In the Quartus II software, unused pins can be set as programmable GND
on a global default basis or they can be individually assigned. Unused pins also have
the option of being set as tri-stated input pins.

I/O Structure

Bus Hold
Each MAX II device I/O pin provides an optional bus-hold feature. The bus-hold
circuitry can hold the signal on an I/O pin at its last-driven state. Since the bus-hold
feature holds the last-driven state of the pin until the next input signal is present, an
external pull-up or pull-down resistor is not necessary to hold a signal level when the
bus is tri-stated.
The bus-hold circuitry also pulls undriven pins away from the input threshold
voltage where noise can cause unintended high-frequency switching. The designer
can select this feature individually for each I/O pin. The bus-hold output will drive
no higher than VCCIO to prevent overdriving signals. If the bus-hold feature is enabled,
the device cannot use the programmable pull-up option.
The bus-hold circuitry uses a resistor to pull the signal level to the last driven state.
The DC and Switching Characteristics chapter in the MAX II Device Handbook gives the
specific sustaining current for each VCCIO voltage level driven through this resistor and
overdrive current used to identify the next-driven input level.
The bus-hold circuitry is only active after the device has fully initialized. The bus-hold
circuit captures the value on the pin present at the moment user mode is entered.
Programmable Pull-Up Resistor
Each MAX II device I/O pin provides an optional programmable pull-up resistor
during user mode. If the designer enables this feature for an I/O pin, the pull-up
resistor holds the output to the VCCIO level of the output pin’s bank.
1
The programmable pull-up resistor feature should not be used at the same time as the
bus-hold feature on a given I/O pin.
Programmable Input Delay
The MAX II IOE includes a programmable input delay that is activated to ensure zero
hold times. A path where a pin directly drives a register, with minimal routing
between the two, may require the delay to ensure zero hold time. However, a path
where a pin drives a register through long routing or through combinational logic
may not require the delay to achieve a zero hold time. The Quartus II software uses
this delay to ensure zero hold times when needed.
MultiVolt I/O Interface
The MAX II architecture supports the MultiVolt I/O interface feature, which allows
MAX II devices in all packages to interface with systems of different supply voltages.
The devices have one set of VCC pins for internal operation (VCCINT), and up to four
sets for input buffers and I/O output driver buffers (VCCIO), depending on the number
of I/O banks available in the devices where each set of VCC pins powers one I/O
bank. The EPM240 and EPM570 devices have two I/O banks respectively while the
EPM1270 and EPM2210 devices have four I/O banks respectively.

Connect VCCIO pins to either a 1.5-V, 1.8 V, 2.5-V, or 3.3-V power supply, depending
on the output requirements. The output levels are compatible with systems of the
same voltage as the power supply (that is, when VCCIO pins are connected to a 1.5-V
power supply, the output levels are compatible with 1.5-V systems). When VCCIO
pins are connected to a 3.3-V power supply, the output high is 3.3 V and is compatible
with 3.3-V or 5.0-V systems. Table 2–7 summarizes MAX II MultiVolt I/O support.

Notes to Table 2–7:
(1) To drive inputs higher than VCCIO but less than 4.0 V including the overshoot, disable the I/O clamp diode. However, to drive 5.0-V inputs to the
device, enable the I/O clamp diode to prevent VI from rising above 4.0 V.
(2) When VCCIO = 1.8 V, a MAX II device can drive a 1.5-V device with 1.8-V tolerant inputs.
(3) When VCCIO = 2.5 V, a MAX II device can drive a 1.5-V or 1.8-V device with 2.5-V tolerant inputs.
(4) When VCCIO = 3.3 V and a 2.5-V input signal feeds an input pin, the VCCIO supply current will be slightly larger than expected.
(5) MAX II devices can be 5.0-V tolerant with the use of an external resistor and the internal I/O clamp diode on the EPM1270 and EPM2210
devices.
(6) When VCCIO = 3.3 V, a MAX II device can drive a 1.5-V, 1.8-V, or 2.5-V device with 3.3-V tolerant inputs.
(7) When VCCIO = 3.3 V, a MAX II device can drive a device with 5.0-V TTL inputs but not 5.0-V CMOS inputs. In the case of 5.0-V CMOS, opendrain setting with internal I/O clamp diode (available only on EPM1270 and EPM2210 devices) and external resistor is required.

Introduction
This chapter discusses how to use the IEEE Standard 1149.1 Boundary-Scan Test (BST)
circuitry in MAX II devices and includes the following sections:
■
“IEEE Std. 1149.1 (JTAG) Boundary-Scan Support” on page 3–1
■
“In System Programmability” on page 3–4
IEEE Std. 1149.1 (JTAG) Boundary-Scan Support
All MAX® II devices provide Joint Test Action Group (JTAG) boundary-scan test (BST)
circuitry that complies with the IEEE Std. 1149.1-2001 specification. JTAG boundaryscan testing can only be performed at any time after VCCINT and all VCCIO banks have
been fully powered and a tCONFIG amount of time has passed. MAX II devices can also
use the JTAG port for in-system programming together with either the Quartus® II
software or hardware using Programming Object Files (.pof), JamTM Standard Test
and Programming Language (STAPL) Files (.jam), or Jam Byte-Code Files (.jbc).
The JTAG pins support 1.5-V, 1.8-V, 2.5-V, or 3.3-V I/O standards. The supported
voltage level and standard are determined by the VCCIO of the bank where it resides.
The dedicated JTAG pins reside in Bank 1 of all MAX II devices.
MAX II devices support the JTAG instructions shown in Table 3–1.

JTAG Block
The MAX II JTAG block feature allows you to access the JTAG TAP and state signals
when either the USER0 or USER1 instruction is issued to the JTAG TAP. The USER0
and USER1 instructions bring the JTAG boundary-scan chain (TDI) through the user
logic instead of the MAX II device’s boundary-scan cells. Each USER instruction
allows for one unique user-defined JTAG chain into the logic array.
Parallel Flash Loader
The JTAG block ability to interface JTAG to non-JTAG devices is ideal for generalpurpose flash memory devices (such as Intel- or Fujitsu-based devices) that require
programming during in-circuit test. The flash memory devices can be used for FPGA
configuration or be part of system memory. In many cases, the MAX II device is
already connected to these devices as the configuration control logic between the
FPGA and the flash device. Unlike ISP-capable CPLD devices, bulk flash devices do
not have JTAG TAP pins or connections. For small flash devices, it is common to use
the serial JTAG scan chain of a connected device to program the non-JTAG flash
device. This is slow and inefficient in most cases and impractical for large parallel
flash devices. Using the MAX II device’s JTAG block as a parallel flash loader, with
the Quartus II software, to program and verify flash contents provides a fast and costeffective means of in-circuit programming during test. Figure 3–1 shows MAX II
being used as a parallel flash loader.

In System Programmability
MAX II devices can be programmed in-system via the industry standard 4-pin IEEE
Std. 1149.1 (JTAG) interface. In-system programmability (ISP) offers quick, efficient
iterations during design development and debugging cycles. The logic, circuitry, and
interconnects in the MAX II architecture are configured with flash-based SRAM
configuration elements. These SRAM elements require configuration data to be
loaded each time the device is powered. The process of loading the SRAM data is
called configuration. The on-chip configuration flash memory (CFM) block stores the
SRAM element’s configuration data. The CFM block stores the design’s configuration
pattern in a reprogrammable flash array. During ISP, the MAX II JTAG and ISP
circuitry programs the design pattern into the CFM block’s non-volatile flash array.
The MAX II JTAG and ISP controller internally generate the high programming
voltages required to program the CFM cells, allowing in-system programming with
any of the recommended operating external voltage supplies (that is, 3.3 V/2.5 V or
1.8 V for the MAX IIG and MAX IIZ devices). ISP can be performed anytime after
VCCINT and all VCCIO banks have been fully powered and the device has completed the
configuration power-up time. By default, during in-system programming, the I/O
pins are tri-stated and weakly pulled-up to VCCIO to eliminate board conflicts. The insystem programming clamp and real-time ISP feature allow user control of I/O state
or behavior during ISP.
For more information, refer to “In-System Programming Clamp” on page 3–6 and
“Real-Time ISP” on page 3–7.
These devices also offer an ISP_DONE bit that provides safe operation when insystem programming is interrupted. This ISP_DONE bit, which is the last bit
programmed, prevents all I/O pins from driving until the bit is programmed.

IEEE 1532 Support
The JTAG circuitry and ISP instruction set in MAX II devices is compliant to the IEEE
1532-2002 programming specification. This provides industry-standard hardware and
software for in-system programming among multiple vendor programmable logic
devices (PLDs) in a JTAG chain.
The MAX II 1532 BSDL files will be released on the Altera website when available.
Jam Standard Test and Programming Language (STAPL)
The Jam STAPL JEDEC standard, JESD71, can be used to program MAX II devices
with in-circuit testers, PCs, or embedded processors. The Jam byte code is also
supported for MAX II devices. These software programming protocols provide a
compact embedded solution for programming MAX II devices.
f
For more information, refer to the Using Jam STAPL for ISP via an Embedded Processor
chapter in the MAX II Device Handbook.
Programming Sequence
During in-system programming, 1532 instructions, addresses, and data are shifted
into the MAX II device through the TDI input pin. Data is shifted out through the TDO
output pin and compared against the expected data. Programming a pattern into the
device requires the following six ISP steps. A stand-alone verification of a
programmed pattern involves only stages 1, 2, 5, and 6. These steps are automatically
executed by third-party programmers, the Quartus II software, or the Jam STAPL and
Jam Byte-Code Players.
1. Enter ISP—The enter ISP stage ensures that the I/O pins transition smoothly from
user mode to ISP mode.
2. Check ID—Before any program or verify process, the silicon ID is checked. The
time required to read this silicon ID is relatively small compared to the overall
programming time.
3. Sector Erase—Erasing the device in-system involves shifting in the instruction to
erase the device and applying an erase pulse(s). The erase pulse is automatically
generated internally by waiting in the run/test/idle state for the specified erase
pulse time of 500 ms for the CFM block and 500 ms for each sector of the UFM
block.
4. Program—Programming the device in-system involves shifting in the address,
data, and program instruction and generating the program pulse to program the
flash cells. The program pulse is automatically generated internally by waiting in
the run/test/idle state for the specified program pulse time of 75 µs. This process
is repeated for each address in the CFM and UFM blocks.
5. Verify—Verifying a MAX II device in-system involves shifting in addresses,
applying the verify instruction to generate the read pulse, and shifting out the data
for comparison. This process is repeated for each CFM and UFM address.
6. Exit ISP—An exit ISP stage ensures that the I/O pins transition smoothly from ISP
mode to user mode.

Description
UFM Programming
The Quartus II software, with the use of POF, Jam, or JBC files, supports
programming of the user flash memory (UFM) block independent of the logic array
design pattern stored in the CFM block. This allows updating or reading UFM
contents through ISP without altering the current logic array design, or vice versa. By
default, these programming files and methods will program the entire flash memory
contents, which includes the CFM block and UFM contents. The stand-alone
embedded Jam STAPL player and Jam Byte-Code Player provides action commands
for programming or reading the entire flash memory (UFM and CFM together) or
each independently.
f
For more information, refer to the Using Jam STAPL for ISP via an Embedded Processor
chapter in the MAX II Device Handbook.
In-System Programming Clamp
By default, the IEEE 1532 instruction used for entering ISP automatically tri-states all
I/O pins with weak pull-up resistors for the duration of the ISP sequence. However,
some systems may require certain pins on MAX II devices to maintain a specific DC
logic level during an in-field update. For these systems, an optional in-system
programming clamp instruction exists in MAX II circuitry to control I/O behavior
during the ISP sequence. The in-system programming clamp instruction enables the
device to sample and sustain the value on an output pin (an input pin would remain
tri-stated if sampled) or to explicitly set a logic high, logic low, or tri-state value on
any pin. Setting these options is controlled on an individual pin basis using the
Quartus II software.

Real-Time ISP
For systems that require more than DC logic level control of I/O pins, the real-time
ISP feature allows you to update the CFM block with a new design image while the
current design continues to operate in the SRAM logic array and I/O pins. A new
programming file is updated into the MAX II device without halting the original
design’s operation, saving down-time costs for remote or field upgrades. The updated
CFM block configures the new design into the SRAM upon the next power cycle. It is
also possible to execute an immediate configuration of the SRAM without a power
cycle by using a specific sequence of ISP commands. The configuration of SRAM
without a power cycle takes a specific amount of time (tCONFIG). During this time, the
I/O pins are tri-stated and weakly pulled-up to VCCIO.
Design Security
All MAX II devices contain a programmable security bit that controls access to the
data programmed into the CFM block. When this bit is programmed, design
programming information, stored in the CFM block, cannot be copied or retrieved.
This feature provides a high level of design security because programmed data within
flash memory cells is invisible. The security bit that controls this function, as well as
all other programmed data, is reset only when the device is erased. The SRAM is also
invisible and cannot be accessed regardless of the security bit setting. The UFM block
data is not protected by the security bit and is accessible through JTAG or logic array
connections.
Programming with External Hardware
MAX II devices can be programmed by downloading the information via in-circuit
testers, embedded processors, the Altera® ByteblasterMV™, MasterBlaster™,
ByteBlaster™ II, and USB-Blaster cables.
BP Microsystems, System General, and other programming hardware manufacturers
provide programming support for Altera devices. Check their websites for device
support information.

4. Hot Socketing and Power-On Reset in
MAX II Devices
MII51004-2.1
Introduction
MAX® II devices offer hot socketing, also known as hot plug-in or hot swap, and
power sequencing support. Designers can insert or remove a MAX II board in a
system during operation without undesirable effects to the system bus. The hot
socketing feature removes some of the difficulties designers face when using
components on printed circuit boards (PCBs) that contain a mixture of 3.3-, 2.5-, 1.8-,
and 1.5-V devices.
The MAX II device hot socketing feature provides:
■
Board or device insertion and removal
■
Support for any power-up sequence
■
Non-intrusive I/O buffers to system buses during hot insertion
This chapter contains the following sections:
■
“MAX II Hot-Socketing Specifications” on page 4–1
■
“Power-On Reset Circuitry” on page 4–5
MAX II Hot-Socketing Specifications
MAX II devices offer all three of the features required for the hot-socketing capability
listed above without any external components or special design requirements. The
following are hot-socketing specifications:
1
■
The device can be driven before and during power-up or power-down without
any damage to the device itself.
■
I/O pins remain tri-stated during power-up. The device does not drive out before
or during power-up, thereby affecting other buses in operation.
■
Signal pins do not drive the VCCIO or VCCINT power supplies. External input signals
to device I/O pins do not power the device VCCIO or VCCINT power supplies via
internal paths. This is true if the VCCINT and the VCCIO supplies are held at GND.
Altera uses GND as reference for the hot-socketing and I/O buffers circuitry designs.
You must connect the GND between boards before connecting the VCCINT and the VCCIO
power supplies to ensure device reliability and compliance to the hot-socketing
specifications.
Devices Can Be Driven before Power-Up
Signals can be driven into the MAX II device I/O pins and GCLK[3..0] pins before
or during power-up or power-down without damaging the device. MAX II devices
support any power-up or power-down sequence (VCCIO1, VCCIO2, VCCIO3, VCCIO4, VCCINT),
simplifying the system-level design.

Chapter 4: Hot Socketing and Power-On Reset in MAX II Devices
Hot Socketing Feature Implementation in MAX II Devices
I/O Pins Remain Tri-Stated during Power-Up
A device that does not support hot-socketing may interrupt system operation or cause
contention by driving out before or during power-up. In a hot socketing situation, the
MAX II device’s output buffers are turned off during system power-up. MAX II
devices do not drive out until the device attains proper operating conditions and is
fully configured. Refer to “Power-On Reset Circuitry” on page 4–5 for information
about turn-on voltages.
Signal Pins Do Not Drive the VCCIO or VCCINT Power Supplies
MAX II devices do not have a current path from I/O pins or GCLK[3..0] pins to the
VCCIO or VCCINT pins before or during power-up. A MAX II device may be inserted into
(or removed from) a system board that was powered up without damaging or
interfering with system-board operation. When hot socketing, MAX II devices may
have a minimal effect on the signal integrity of the backplane.
AC and DC Specifications
You can power up or power down the VCCIO and VCCINT pins in any sequence. During
hot socketing, the I/O pin capacitance is less than 8 pF. MAX II devices meet the
following hot socketing specifications:
1
■
The hot socketing DC specification is: | IIOPIN | < 300 μA.
■
The hot socketing AC specification is: | IIOPIN | < 8 mA for 10 ns or less.
MAX II devices are immune to latch-up when hot socketing. If the TCK JTAG input
pin is driven high during hot socketing, the current on that pin might exceed the
specifications above.
IIOPIN is the current at any user I/O pin on the device. The AC specification applies
when the device is being powered up or powered down. This specification takes into
account the pin capacitance but not board trace and external loading capacitance.
Additional capacitance for trace, connector, and loading must be taken into
consideration separately. The peak current duration due to power-up transients is
10 ns or less.
The DC specification applies when all VCC supplies to the device are stable in the
powered-up or powered-down conditions.
Hot Socketing Feature Implementation in MAX II Devices
The hot socketing feature turns off (tri-states) the output buffer during the power-up
event (either VCCINT or VCCIO supplies) or power-down event. The hot-socket circuit
generates an internal HOTSCKT signal when either VCCINT or VCCIO is below the
threshold voltage during power-up or power-down. The HOTSCKT signal cuts off the
output buffer to make sure that no DC current (except for weak pull-up leaking) leaks
through the pin. When VCC ramps up very slowly during power-up, VCC may still be
relatively low even after the power-on reset (POR) signal is released and device
configuration is complete.

The POR circuit monitors VCCINT and VCCIO voltage levels and keeps I/O pins tri-stated
until the device has completed its flash memory configuration of the SRAM logic. The
weak pull-up resistor (R) from the I/O pin to VCCIO is enabled during download to
keep the I/O pins from floating. The 3.3-V tolerance control circuit permits the I/O
pins to be driven by 3.3 V before VCCIO and/or VCCINT are powered, and it prevents the
I/O pins from driving out when the device is not fully powered or operational. The
hot socket circuit prevents I/O pins from internally powering VCCIO and VCCINT when
driven by external signals before the device is powered.
f
For information about 5.0-V tolerance, refer to the Using MAX II Devices in MultiVoltage Systems chapter in the MAX II Device Handbook.
Figure 4–2 shows a transistor-level cross section of the MAX II device I/O buffers.
This design ensures that the output buffers do not drive when VCCIO is powered before
VCCINT or if the I/O pad voltage is higher than VCCIO. This also applies for sudden
voltage spikes during hot insertion. The VPAD leakage current charges the 3.3-V
tolerant circuit capacitance.

The CMOS output drivers in the I/O pins intrinsically provide electrostatic discharge
(ESD) protection. There are two cases to consider for ESD voltage strikes: positive
voltage zap and negative voltage zap.
A positive ESD voltage zap occurs when a positive voltage is present on an I/O pin
due to an ESD charge event. This can cause the N+ (Drain)/ P-Substrate junction of
the N-channel drain to break down and the N+ (Drain)/P-Substrate/N+ (Source)
intrinsic bipolar transistor turn on to discharge ESD current from I/O pin to GND.
The dashed line (see Figure 4–3) shows the ESD current discharge path during a
positive ESD zap.

When the I/O pin receives a negative ESD zap at the pin that is less than –0.7 V (0.7 V
is the voltage drop across a diode), the intrinsic
P-Substrate/N+ drain diode is forward biased. Therefore, the discharge ESD current
path is from GND to the I/O pin, as shown in Figure 4–4.

Power-On Reset Circuitry
MAX II devices have POR circuits to monitor VCCINT and VCCIO voltage levels during
power-up. The POR circuit monitors these voltages, triggering download from the
non-volatile configuration flash memory (CFM) block to the SRAM logic, maintaining
tri-state of the I/O pins (with weak pull-up resistors enabled) before and during this
process. When the MAX II device enters user mode, the POR circuit releases the I/O
pins to user functionality. The POR circuit of the MAX II (except MAX IIZ) device
continues to monitor the VCCINT voltage level to detect a brown-out condition. The
POR circuit of the MAX IIZ device does not monitor the VCCINT voltage level after the
device enters into user mode. More details are provided in the following sub-sections.

Chapter 4: Hot Socketing and Power-On Reset in MAX II Devices
Power-On Reset Circuitry
Power-Up Characteristics
When power is applied to a MAX II device, the POR circuit monitors VCCINT and
begins SRAM download at an approximate voltage of 1.7 V or 1.55 V for MAX IIG and
MAX IIZ devices. From this voltage reference, SRAM download and entry into user
mode takes 200 to 450 µs maximum, depending on device density. This period of time
is specified as tCONFIG in the power-up timing section of the DC and Switching
Characteristics chapter in the MAX II Device Handbook.
Entry into user mode is gated by whether all VCCIO banks are powered with sufficient
operating voltage. If VCCINT and VCCIO are powered simultaneously, the device enters
user mode within the tCONFIG specifications. If VCCIO is powered more than tCONFIG after
VCCINT, the device does not enter user mode until 2 µs after all VCCIO banks are powered.
For MAX II and MAX IIG devices, when in user mode, the POR circuitry continues to
monitor the VCCINT (but not VCCIO) voltage level to detect a brown-out condition. If
there is a VCCINT voltage sag at or below 1.4 V during user mode, the POR circuit resets
the SRAM and tri-states the I/O pins. Once VCCINT rises back to approximately 1.7 V
(or 1.55 V for MAX IIG devices), the SRAM download restarts and the device begins
to operate after tCONFIG time has passed.
For MAX IIZ devices, the POR circuitry does not monitor the VCCINT and VCCIO voltage
levels after the device enters user mode. If there is a VCCINT voltage sag below 1.4 V
during user mode, the functionality of the device will not be guaranteed and you
must power down the VCCINT to 0 V for a minimum of 10 µs before powering the VCCINT
and VCCIO up again. Once VCCINT rises from 0 V back to approximately 1.55 V, the
SRAM download restarts and the device begins to operate after tCONFIG time has
passed.
Figure 4–5 shows the voltages for POR of MAX II, MAX IIG, and MAX IIZ devices
during power-up into user mode and from user mode to power-down or brown-out.

After SRAM configuration, all registers in the device are cleared and released into
user function before I/O tri-states are released. To release clears after tri-states are
released, use the DEV_CLRn pin option. To hold the tri-states beyond the power-up
configuration time, use the DEV_OE pin option.

Notes to Table 5–2:
(1) MAX II device in-system programming and/or user flash memory (UFM) programming via JTAG or logic array is not guaranteed outside the
recommended operating conditions (for example, if brown-out occurs in the system during a potential write/program sequence to the UFM,
users are recommended to read back UFM contents and verify against the intended write data).
(2) Minimum DC input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V for input currents less than 100 mA and periods shorter
than 20 ns.
(3) During transitions, the inputs may overshoot to the voltages shown in the following table based upon input duty cycle. The DC case is equivalent
to 100% duty cycle. For more information about 5.0-V tolerance, refer to the Using MAX II Devices in Multi-Voltage Systems chapter in the MAX
II Device Handbook.

(4) All pins, including clock, I/O, and JTAG pins, may be driven before VCCINT and VCCIO are powered.
(5) MAX IIZ devices are only available in the commercial temperature range.
(6) For the extended temperature range of 100 to 125º C, MAX II UFM programming (erase/write) is only supported via the JTAG interface. UFM
programming via the logic array interface is not guaranteed in this range.

Notes to Table 5–4:
(1) Typical values are for TA = 25 °C, VCCINT = 3.3 or 2.5 V, and VCCIO = 1.5 V, 1.8 V, 2.5 V, or 3.3 V.
(2) This value is specified for normal device operation. The value may vary during power-up. This applies for all VCCIO settings (3.3, 2.5,
1.8, and 1.5 V).
(3) VI = ground, no load, no toggling inputs.
(4) This value applies to commercial and industrial range devices. For extended temperature range devices, the VSCHMITT typical value is
300 mV for VCCIO = 3.3 V and 120 mV for VCCIO = 2.5 V.
(5) The TCK input is susceptible to high pulse glitches when the input signal fall time is greater than 200 ns for all I/O standards.
(6) This is a peak current value with a maximum duration of tCONFIG time.
(7) Pin pull-up resistance values will lower if an external source drives the pin higher than VCCIO.

Power Consumption
Designers can use the Altera® PowerPlay Early Power Estimator and PowerPlay
Power Analyzer to estimate the device power.
f
For more information about these power analysis tools, refer to the Understanding and
Evaluating Power in MAX II Devices chapter in the MAX II Device Handbook and the
PowerPlay Power Analysis chapter in volume 3 of the Quartus II Handbook.
Timing Model and Specifications
MAX II devices timing can be analyzed with the Altera Quartus® II software, a variety
of popular industry-standard EDA simulators and timing analyzers, or with the
timing model shown in Figure 5–2.
MAX II devices have predictable internal delays that enable the designer to determine
the worst-case timing of any design. The software provides timing simulation, pointto-point delay prediction, and detailed timing analysis for device-wide performance
evaluation.

Data-Out
The timing characteristics of any signal path can be derived from the timing model
and parameters of a particular device. External timing parameters, which represent
pin-to-pin timing delays, can be calculated as the sum of internal parameters.
f
Refer to the Understanding Timing in MAX II Devices chapter in the MAX II Device
Handbook for more information.
This section describes and specifies the performance, internal, external, and UFM
timing specifications. All specifications are representative of the worst-case supply
voltage and junction temperature conditions.
Preliminary and Final Timing
Timing models can have either preliminary or final status. The Quartus® II software
issues an informational message during the design compilation if the timing models
are preliminary. Table 5–13 shows the status of the MAX II device timing models.
Preliminary status means the timing model is subject to change. Initially, timing
numbers are created using simulation results, process data, and other known
parameters. These tests are used to make the preliminary numbers as close to the
actual timing parameters as possible.
Final timing numbers are based on actual device operation and testing. These
numbers reflect the actual performance of the device under the worst-case voltage
and junction temperature conditions.

Notes to Table 5–16:
(1) Delay numbers for tGLOB differ for each device density and speed grade. The delay numbers for tGLOB, shown in Table 5–16, are based on an
EPM240 device target.
(2) Refer to Table 5–29 and 5–21 for delay adders associated with different I/O standards, drive strengths, and slew rates.
(3) Refer to Table 5–19 and 5–13 for tXZ delay adders associated with different I/O standards, drive strengths, and slew rates.
(4) Refer to Table 5–17 and 5–12 for tZX delay adders associated with different I/O standards, drive strengths, and slew rates.
Table 5–17 through Table 5–20 show the adder delays for tZX and tXZ microparameters
when using an I/O standard other than 3.3-V LVTTL with 16 mA drive strength.

External Timing Parameters
External timing parameters are specified by device density and speed grade. All
external I/O timing parameters shown are for the 3.3-V LVTTL I/O standard with the
maximum drive strength and fast slew rate. For external I/O timing using standards
other than LVTTL or for different drive strengths, use the I/O standard input and
output delay adders in Table 5–27 through Table 5–28.

External Timing I/O Delay Adders
The I/O delay timing parameters for I/O standard input and output adders, and
input delays are specified by speed grade independent of device density.
Table 5–27 through Table 5–28 show the adder delays associated with I/O pins for all
packages. The delay numbers for –3, –4, and –5 speed grades shown in Table 5–27
through Table 5–30 are based on an EPM1270 device target, while –6 and –7 speed
grade values are based on an EPM570Z device target. If an I/O standard other than
3.3-V LVTTL is selected, add the input delay adder to the external tSU timing
parameters shown in Table 5–23 through Table 5–26. If an I/O standard other than
3.3-V LVTTL with 16 mA drive strength and fast slew rate is selected, add the output
delay adder to the external tCO and tPD shown in Table 5–23 through Table 5–26.

Notes to Table 5–31:
(1) Minimum clock period specified for 10 pF load on the TDO pin. Larger loads on TDO will degrade the maximum TCK
frequency.
(2) This specification is shown for 3.3-V LVTTL/LVCMOS and 2.5-V LVTTL/LVCMOS operation of the JTAG pins. For 1.8-V
LVTTL/LVCMOS and 1.5-V LVCMOS, the tJPSU minimum is 6 ns and tJPCO, tJPZX, and tJPXZ are maximum values at 35 ns.
