Description
The Atmel® ATF1502AS(L) is a high-performance, high-density Complex Programmable Logic Device (CPLD)
which utilizes the Atmel proven electrically-erasable technology. With 32 logic macrocells and up to 36 inputs, it
easily integrates logic from several TTL, SSI, MSI, LSI, and classic PLDs. The ATF1502AS(L)’s enhanced
routing switch matrices increase usable gate count and the odds of successful pin-locked design modifications.
The ATF1502AS(L) has up to 32 bi-directional I/O pins and four dedicated input pins, depending on the type of
device package selected. Each dedicated pin can serve as a global control signal, register clock, register reset,
or output enable. Each of these control signals can be selected for use individually within each macrocell.
Each of the 32 macrocells generates a buried feedback which goes to the global bus. Each input and I/O pin
also feeds into the global bus. The switch matrix in each logic block then selects 40 individual signals from the
global bus. Each macrocell also generates a foldback logic term that goes to a regional bus. Cascade logic
between macrocells in the ATF1502AS(L) allows fast, efficient generation of complex logic functions. The
ATF1502AS(L) contains four such logic chains, each capable of creating sum term logic with a fan-in of up to
40 product terms.
The ATF1502AS(L) macrocell, shown in Figure 1, is flexible enough to support highly complex logic functions
operating at high speed. The macrocell consists of five sections:

Unused product terms are automatically disabled by the compiler to decrease power consumption. A security
fuse, when programmed, protects the contents of the ATF1502AS(L). Two bytes (16 bits) of User Signature are
accessible to the user for purposes such as storing project name, part number, revision, or date. The User
Signature is accessible regardless of the state of the security fuse.
The ATF1502AS(L) device is an In-System Programmable (ISP) device. It uses the industry standard 4-pin
JTAG interface (IEEE Std. 1149.1), and is fully compliant with JTAG’s Boundary-scan Description Language
(BSDL). ISP allows the device to be programmed without removing it from the printed circuit board. In addition
to simplifying the manufacturing flow, ISP also allows design modifications to be made in the field via software.

Logic
Description
Each ATF1502AS(L) macrocell has five product terms. Each product term receives as its inputs
all signals from both the global bus and regional bus.
The Product Term Select Multiplexer (PTMUX) allocates the five product terms as needed to the
macrocell logic gates and control signals. The PTMUX programming is determined by the design
compiler, which selects the optimum macrocell configuration.
The ATF1502AS(L) logic structure is designed to efficiently support all types of logic. Within a
single macrocell, all the product terms can be routed to the OR gate, creating a 5-input AND/OR
sum term. With the addition of the CASIN from neighboring macrocells, this can be expanded to
as many as 40 product terms with little additional delay.
The macrocell’s XOR gate allows efficient implementation of compare and arithmetic functions.
One input to the XOR comes from the OR sum term. The other XOR input can be a product term
or a fixed high or low level. For combinatorial outputs, the fixed level input allows polarity
selection. For registered functions, the fixed levels allow DeMorgan minimization of product
terms. The XOR gate is also used to emulate T-type and JK-type flip-flops.
The ATF1502AS(L) flip-flop has very flexible data and control functions. The data input can come
from either the XOR gate, from a separate product term, or directly from the I/O pin. Selecting the
separate product term allows creation of a buried registered feedback within a combinatorial
output macrocell. (This feature is automatically implemented by the fitter software). In addition to
D, T, JK, and SR operation, the flip-flop can be configured as a flow-through latch. In this mode,
data passes through when the clock is high and is latched when the clock is low.
Flip-flop
The clock itself can be either one of the Global CLK signals (GCK[0:2]) or an individual product
term. The flip-flop changes state on the clock’s rising edge. When the GCK signal is used as the
clock, one of the macrocell product terms can be selected as a clock enable. When the clock
enable function is active and the enable signal (product term) is low, all clock edges are ignored.
The flip-flop’s Asynchronous Reset (AR) signal can be either the Global Clear (GCLEAR), a
product term, or always off. AR can also be a logic OR of GCLEAR with a product term. The
Asynchronous Preset (AP) can be a product term or always off.
The ATF1502AS(L) macrocell output can be selected as registered or combinatorial. The extra
buried feedback signal can be either combinatorial or a registered signal regardless of whether
the output is combinatorial or registered. (This enhancement function is automatically
implemented by the fitter software.) Feedback of a buried combinatorial output allows the
creation of a second latch within a macrocell.
6
Extra Feedback
I/O Control: The Output Enable Multiplexer (MOE) controls the output enable signal.
Global Bus/Switch
Matrix
The global bus contains all input and I/O pin signals as well as the buried feedback signal from all
32 macrocells. The switch matrix in each logic block receives as its inputs all signals from the
global bus. Under software control, up to 40 of these signals can be selected as inputs to the
logic block.
Foldback Bus
Each macrocell also generates a foldback product term. This signal goes to the regional bus and
is available to four macrocells. The foldback is an inverse polarity of one of the macrocell’s
product terms. The four foldback terms in each region allow generation of high fan-in sum terms
(up to nine product terms) with little additional delay.
Each I/O can be individually configured as an input, output, or for bi-directional
operation. The output enable for each macrocell can be selected from the true or
compliment of the two output enable pins, a subset of the I/O pins, or a subset of the I/O
macrocells. This selection is automatically done by the fitter software when the I/O is
configured as an input, all macrocell resources are still available, including the buried
feedback, expander, and cascade logic.

Programmable Pin-keeper Option for Inputs and I/Os
The ATF1502AS(L) offers the option of programming all input and I/O pins so the pin-keeper circuits can be
utilized. When any pin is driven high or low and then subsequently left floating, it will stay at that previous high or
low level. This circuitry prevents unused input and I/O lines from floating to intermediate voltage levels, which
causes unnecessary power consumption and system noise. The keeper circuits eliminate the need for external
pull-up resistors and eliminate their DC power consumption.

Speed/Power Management
The ATF1502AS(L) has several built-in speed and power management features. The ATF1502AS(L) contains
circuitry which automatically puts the device into a low-power standby mode when no logic transitions are occurring.
This not only reduces power consumption during inactive periods, but also provides proportional power savings for
most applications running at system speeds below 50MHz. This feature may be selected as a design option.
To further reduce power, each ATF1502AS(L) macrocell has a reduced-power bit feature. This feature allows
individual macrocells to be configured for maximum power savings. This feature may be selected as a design
option.
The ATF1502AS(L) also has an optional power-down mode. In this mode, current drops to below 10mA. When
the power-down option is selected, either PD1 or PD2 pins (or both) can be used to power down the part. The
power-down option is selected in the design source file. When enabled, the device goes into power-down when
either PD1 or PD2 is high. In the power-down mode, all internal logic signals are latched and held, as are any
enabled outputs.
All pin transitions are ignored until the PD pin is brought low. When the power-down feature is enabled, the PD1
or PD2 pin cannot be used as a logic input or output; however, the pin’s macrocell may still be used to generate
buried foldback and cascade logic signals.
All power-down AC characteristic parameters are computed from external input or I/O pins, with reduced-power
bit turned on. For macrocells in reduced-power mode (reduced-power bit turned on), the reduced-power adder,
tRPA, must be added to the AC parameters, which include the data paths tLAD, tLAC, tIC, tACL, tACH, and tSEXP.
The ATF1502AS(L) macrocell also has an option whereby the power can be reduced on a per-macrocell basis.
By enabling this power-down option, macrocells that are not used in an application can be turned down, thereby
reducing the overall power consumption of the device.
Each output also has individual slew rate control. This may be used to reduce system noise by slowing down
outputs that do not need to operate at maximum speed. Outputs default to slow switching, and may be specified
as fast switching in the design file.
6.
Design Software Support
ATF1502AS(L) designs are supported by several third-party tools. Automated fitters allow logic synthesis using
a variety of high-level description languages and formats.
7.
Power-up Reset
The ATF1502AS(L) is designed with a power-up reset, a feature critical for state machine initialization. At a
point delayed slightly from VCC crossing VRST, all registers will be initialized, and the state of each output will
depend on the polarity of its buffer. However, due to the asynchronous nature of reset and uncertainty of how
VCC actually rises in the system, the following conditions are required:



The VCC rise must be monotonic,
After reset occurs, all input and feedback setup times must be met before driving the clock pin high, and,
The clock must remain stable during TD.
The ATF1502AS(L) has two options for the hysteresis about the reset level, VRST, Small and Large. During the
fitting process, users may configure the device with the Power-up Reset hysteresis set to Large or Small. Atmel
POF2JED users may select the Large option by including the flag “-power_reset” on the command line after
“filename.POF”. To allow the registers to be properly reinitialized with the Large hysteresis option selected, the
following condition is added:

If VCC falls below 2.0V, it must shut off completely before the device is turned on again.
When the Large hysteresis option is active, ICC is reduced by several hundred micro amps as well.

Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATF1502AS(L) fuse patterns. Once
programmed, fuse verify is inhibited; however, the 16-bit User Signature remains accessible.
9.
Programming
ATF1502AS(L) devices are In-System Programmable (ISP) devices utilizing the 4-pin JTAG protocol. This
capability eliminates package handling normally required for programming and facilitates rapid design iterations
and field changes.
Atmel provides ISP hardware and software to allow programming of the ATF1502AS(L) via the PC. ISP is
performed by using either a download cable, a comparable board tester, or a simple microprocessor interface.
When using the ISP hardware or software to program the ATF1502AS(L) devices, four I/O pins must be
reserved for the JTAG interface. However, the logic features that the macrocells have associated with these I/O
pins are still available to the design for burned logic functions.
To facilitate ISP programming by the Automated Test Equipment (ATE) vendors, Serial Vector Format (SVF)
files can be created by Atmel-provided software utilities.
ATF1502AS(L) devices can also be programmed using standard third-party programmers. With a third-party
programmer, the JTAG ISP port can be disabled, thereby allowing four additional I/O pins to be used for logic.
Contact your local Atmel representatives or Atmel PLD applications for details.
10.
ISP Programming Protection
The ATF1502AS(L) has a special feature which locks the device and prevents the inputs and I/O from driving if
the programming process is interrupted for any reason. The inputs and I/O default to high-Z state during such a
condition. In addition, the pin-keeper option preserves the previous state of the input and I/O PMS during
programming.
All ATF1502AS(L) devices are initially shipped in the erased state, thereby making them ready to use for ISP.

Power-down Mode
The ATF1502AS(L) includes an optional pin-controlled power-down feature. When this mode is enabled, the
PD pin acts as the power-down pin. When the PD pin is high, the device supply current is reduced to less than
5mA. During power-down, all output data and internal logic states are latched and held. Therefore, all registered
and combinatorial output data remain valid. Any outputs that were in a high-Z state at the onset will remain at
high-Z. During power-down, all input signals except the power-down pin are blocked. Input and I/O hold latches
remain active to ensure the pins do not float to indeterminate levels, further reducing system power. The
power-down pin feature is enabled in the logic design file. Designs using the power-down pin may not use the
PD pin logic array input; however, all other PD pin macrocell resources may still be used, including the buried
feedback and foldback product term array inputs.

JTAG-BST/ISP Overview
The JTAG boundary-scan testing is controlled by the Test Access Port (TAP) controller in the ATF1502AS(L).
The boundary-scan technique involves the inclusion of a shift-register stage (contained in a Boundary-Scan
Cell) adjacent to each component so signals at component boundaries can be controlled and observed using
scan testing methods. Each input pin and I/O pin has its own Boundary-Scan Cell (BSC) to support
Boundary-Scan Testing (BST). The ATF1502AS(L) does not include a Test Reset (TRST) input pin because the
TAP controller is automatically reset at power-up. The five JTAG modes supported include:





SAMPLE/PRELOAD
EXTEST
BYPASS
IDCODE
HIGHZ
The ATF1502AS(L) ISP can fully be described using JTAG’s BSDL as described in IEEE Standard 1149.1b.
This allows ATF1502AS(L) programming to be described and implemented using any one of the third-party
development tools supporting this standard.
The ATF1502AS(L) has the option of using four JTAG-standard I/O pins for BST and ISP purposes. The
ATF1502AS(L) is programmable through the four JTAG pins using the IEEE standard JTAG programming
protocol established by IEEE Standard 1149.1 using 5V TTL-level programming signals from the ISP interface
for in-system programming. The JTAG feature is a programmable option. If JTAG (BST or ISP) is not needed,
then the four JTAG control pins are available as I/O pins.
13.
JTAG Boundary-scan Cell (BSC) Testing
The ATF1502AS(L) contains up to 32 I/O pins and four input pins, depending on the device type and package
type selected. Each input pin and I/O pin has its own BSC in order to support BST as described in detail by IEEE
Standard 1149.1. A typical BSC consists of three capture registers or scan registers and up to two update
registers. There are two types of BSCs, one for input or I/O pin and one for the macrocells. The BSCs in the
device are chained together through the capture registers. Input to the capture register chain is fed in from the
TDI pin while the output is directed to the TDO pin. Capture registers are used to capture active device data
signals, to shift data in and out of the device, and to load data into the update registers. Control signals are
generated internally by the JTAG TAP controller. The BSC configuration for the input and I/O pins and
macrocells is shown below.

PCI Compliance
The ATF1502AS(L) supports the growing need in the industry to support the new Peripheral Component
Interconnect (PCI) interface standard in PCI-based designs and specifications. The PCI interface calls for high
current drivers, which are much larger than the traditional TTL drivers. In general, PLDs and FPGAs parallel
outputs to support the high current load required by the PCI interface. The ATF1502AS(L) allows this without
contributing to system noise while delivering low output to output skew. Having a programmable high drive
option is also possible without increasing output delay or pin capacitance.
