Introduction
LatticeECP/EC Family Data Sheet
Lattice Semiconductor
Introduction
The LatticeECP/EC family of FPGA devices has been optimized to deliver mainstream FPGA features at low cost.
For maximum performance and value, the LatticeECP (EConomy Plus) FPGA concept combines an efficient FPGA
fabric with high-speed dedicated functions. Lattice’s first family to implement this approach is the LatticeECP-DSP
(EConomy Plus DSP) family, providing dedicated high-performance DSP blocks on-chip. The LatticeEC™ (EConomy) family supports all the general purpose features of LatticeECP devices without dedicated function blocks to
achieve lower cost solutions.
The LatticeECP/EC FPGA fabric, which was designed from the outset with low cost in mind, contains all the critical
FPGA elements: LUT-based logic, distributed and embedded memory, PLLs and support for mainstream I/Os.
Dedicated DDR memory interface logic is also included to support this memory that is becoming increasingly prevalent in cost-sensitive applications.
The ispLEVER® design tool from Lattice allows large complex designs to be efficiently implemented using the LatticeECP/EC family of FPGA devices. Synthesis library support for LatticeECP/EC is available for popular logic synthesis tools. The ispLEVER tool uses the synthesis tool output along with the constraints from its floor planning
tools to place and route the design in the LatticeECP/EC device. The ispLEVER tool extracts the timing from the
routing and back-annotates it into the design for timing verification.
Lattice provides many pre-designed IP (Intellectual Property) ispLeverCORE™ modules for the LatticeECP/EC
family. By using these IPs as standardized blocks, designers are free to concentrate on the unique aspects of their
design, increasing their productivity.

Preliminary Data Sheet
Architecture Overview
The LatticeECP™-DSP and LatticeEC™ architectures contain an array of logic blocks surrounded by Programmable I/O Cells (PIC). Interspersed between the rows of logic blocks are rows of sysMEM Embedded Block RAM
(EBR) as shown in Figures 2-1 and 2-2. In addition, LatticeECP-DSP supports an additional row of DSP blocks as
shown in Figure 2-2.
There are two kinds of logic blocks, the Programmable Functional Unit (PFU) and Programmable Functional unit
without RAM/ROM (PFF). The PFU contains the building blocks for logic, arithmetic, RAM, ROM and register functions. The PFF block contains building blocks for logic, arithmetic and ROM functions. Both PFU and PFF blocks
are optimized for flexibility allowing complex designs to be implemented quickly and efficiently. Logic Blocks are
arranged in a two-dimensional array. Only one type of block is used per row. The PFU blocks are used on the outside rows. The rest of the core consists of rows of PFF blocks interspersed with rows of PFU blocks. For every
three rows of PFF blocks there is a row of PFU blocks.
Each PIC block encompasses two PIOs (PIO pairs) with their respective sysIO interfaces. PIO pairs on the left and
right edges of the device can be configured as LVDS transmit/receive pairs. sysMEM EBRs are large dedicated fast
memory blocks. They can be configured as RAM or ROM.
The PFU, PFF, PIC and EBR Blocks are arranged in a two-dimensional grid with rows and columns as shown in
Figure 2-1. The blocks are connected with many vertical and horizontal routing channel resources. The place and
route software tool automatically allocates these routing resources.
At the end of the rows containing the sysMEM Blocks are the sysCLOCK Phase Locked Loop (PLL) Blocks. These
PLLs have multiply, divide and phase shifting capability; they are used to manage the phase relationship of the
clocks. The LatticeECP/EC architecture provides up to four PLLs per device.
Every device in the family has a JTAG Port with internal Logic Analyzer (ispTRACY) capability. The sysCONFIG™
port which allows for serial or parallel device configuration. The LatticeECP/EC devices use 1.2V as their core voltage.

PFU and PFF Blocks
The core of the LatticeECP/EC devices consists of PFU and PFF blocks. The PFUs can be programmed to perform
Logic, Arithmetic, Distributed RAM and Distributed ROM functions. PFF blocks can be programmed to perform
Logic, Arithmetic and ROM functions. Except where necessary, the remainder of the data sheet will use the term
PFU to refer to both PFU and PFF blocks.
Each PFU block consists of four interconnected slices, numbered 0-3 as shown in Figure 2-3. All the interconnections to and from PFU blocks are from routing. There are 53 inputs and 25 outputs associated with each PFU block.

Each slice contains two LUT4 lookup tables feeding two registers (programmed to be in FF or Latch mode), and
some associated logic that allows the LUTs to be combined to perform functions such as LUT5, LUT6, LUT7 and
LUT8. There is control logic to perform set/reset functions (programmable as synchronous/asynchronous), clock
select, chip-select and wider RAM/ROM functions. Figure 2-4 shows an overview of the internal logic of the slice.
The registers in the slice can be configured for positive/negative and edge/level clocks.
There are 14 input signals: 13 signals from routing and one from the carry-chain (from adjacent slice or PFU).
There are 7 outputs: 6 to routing and one to carry-chain (to adjacent PFU). Table 2-1 lists the signals associated
with each slice.

Modes of Operation
Each Slice is capable of four modes of operation: Logic, Ripple, RAM and ROM. The Slice in the PFF is capable of
all modes except RAM. Table 2-2 lists the modes and the capability of the Slice blocks.

Logic Mode: In this mode, the LUTs in each Slice are configured as 4-input combinatorial lookup tables. A LUT4
can have 16 possible input combinations. Any logic function with four inputs can be generated by programming this
lookup table. Since there are two LUT4s per Slice, a LUT5 can be constructed within one Slice. Larger lookup
tables such as LUT6, LUT7 and LUT8 can be constructed by concatenating other Slices.
Ripple Mode: Ripple mode allows the efficient implementation of small arithmetic functions. In ripple mode, the following functions can be implemented by each Slice:

- A not-equal-to B
- A less-than-or-equal-to B
Two additional signals: Carry Generate and Carry Propagate are generated per Slice in this mode, allowing fast
arithmetic functions to be constructed by concatenating Slices.
RAM Mode: In this mode, distributed RAM can be constructed using each LUT block as a 16x1-bit memory.
Through the combination of LUTs and Slices, a variety of different memories can be constructed.
The Lattice design tools support the creation of a variety of different size memories. Where appropriate, the software will construct these using distributed memory primitives that represent the capabilities of the PFU. Table 2-3
shows the number of Slices required to implement different distributed RAM primitives. Figure 2-5 shows the distributed memory primitive block diagrams. Dual port memories involve the pairing of two Slices, one Slice functions
as the read-write port. The other companion Slice supports the read-only port. For more information on using RAM
in LatticeECP/EC devices, please see details of additional technical documentation at the end of this data sheet.

Routing
There are many resources provided in the LatticeECP/EC devices to route signals individually or as busses with
related control signals. The routing resources consist of switching circuitry, buffers and metal interconnect (routing)
segments.
The inter-PFU connections are made with x1 (spans two PFU), x2 (spans three PFU) and x6 (spans seven PFU).
The x1 and x2 connections provide fast and efficient connections in horizontal and vertical directions. The x2 and
x6 resources are buffered allowing both short and long connections routing between PFUs.
The ispLEVER design tool takes the output of the synthesis tool and places and routes the design. Generally, the
place and route tool is completely automatic, although an interactive routing editor is available to optimize the
design.
Clock Distribution Network
The clock inputs are selected from external I/O, the sysCLOCK™ PLLs or routing. These clock inputs are fed
through the chip via a clock distribution system.
Primary Clock Sources
LatticeECP/EC devices derive clocks from three primary sources: PLL outputs, dedicated clock inputs and routing.
LatticeECP/EC devices have two to four sysCLOCK PLLs, located on the left and right sides of the device. There
are four dedicated clock inputs, one on each side of the device. Figure 2-6 shows the 20 primary clock sources.

LatticeECP/EC devices have four secondary clock resources per quadrant. The secondary clock branches are
tapped at every PFU. These secondary clock networks can also be used for controls and high fanout data. These
secondary clocks are derived from four clock input pads and 16 routing signals as shown in Figure 2-7.

The clock routing structure in LatticeECP/EC devices consists of four Primary Clock lines and a Secondary Clock
network per quadrant. The primary clocks are generated from MUXs located in each quadrant. Figure 2-8 shows
this clock routing. The four secondary clocks are generated from MUXs located in each quadrant as shown in
Figure 2-9. Each slice derives its clock from the primary clock lines, secondary clock lines and routing as shown in
Figure 2-10.

sysCLOCK Phase Locked Loops (PLLs)
The PLL clock input, from pin or routing, feeds into an input clock divider. There are three sources of feedback signal to the feedback divider: from the CLKOP, from the clock net, or from an external pin. There is a PLL_LOCK signal to indicate that VCO has locked on to the input clock signal. Figure 2-11 shows the sysCLOCK PLL diagram.
The setup and hold times of the device can be improved by programming a delay in the feedback or input path of
the PLL which will advance or delay the output clock with reference to the input clock. This delay can be either programmed during configuration or can be adjusted dynamically. In dynamic mode, the PLL may lose lock after

adjustment and not relock until the tLOCK parameter has been satisfied. Additionally, the phase and duty cycle block
allows the user to adjust the phase and duty cycle of the CLKOS output.
The sysCLOCK PLLs provide the ability to synthesize clock frequencies. Each PLL has four dividers associated
with it: input clock divider, feedback divider, post scalar divider and secondary clock divider. The input clock divider
is used to divide the input clock signal, while the feedback divider is used to multiply the input clock signal. The post
scalar divider allows the VCO to operate at higher frequencies than the clock output, thereby increasing the frequency range. The secondary divider is used to derive lower frequency outputs.

Dynamic Clock Select (DCS)
The DCS is a global clock buffer with smart multiplexer functions. It takes two independent input clock sources and
outputs a clock signal without any glitches or runt pulses. This is achieved irrespective of where the select signal is
toggled. There are eight DCS blocks per device, located in pairs at the center of each side. Figure 2-13 illustrates
the DCS Block Macro.

sysMEM Memory
The LatticeECP/EC family of devices contain a number of sysMEM Embedded Block RAM (EBR). The EBR consists of a 9-Kbit RAM, with dedicated input and output registers.
sysMEM Memory Block
The sysMEM block can implement single port, dual port or pseudo dual port memories. Each block can be used in
a variety of depths and widths as shown in Table 2-6.

Bus Size Matching
All of the multi-port memory modes support different widths on each of the ports. The RAM bits are mapped LSB
word 0 to MSB word 0, LSB word 1 to MSB word 1 and so on. Although the word size and number of words for
each port varies, this mapping scheme applies to each port.
RAM Initialization and ROM Operation
If desired, the contents of the RAM can be pre-loaded during device configuration. By preloading the RAM block
during the chip configuration cycle and disabling the write controls, the sysMEM block can also be utilized as a
ROM.

Memory Cascading
Larger and deeper blocks of RAMs can be created using EBR sysMEM Blocks. Typically, the Lattice design tools
cascade memory transparently, based on specific design inputs.
Single, Dual and Pseudo-Dual Port Modes
Figure 2-15 shows the four basic memory configurations and their input/output names. In all the sysMEM RAM
modes the input data and address for the ports are registered at the input of the memory array. The output data of
the memory is optionally registered at the output.

The EBR memory supports three forms of write behavior for single port or dual port operation:
1. Normal – data on the output appears only during read cycle. During a write cycle, the data (at the current
address) does not appear on the output.
2. Write Through – a copy of the input data appears at the output of the same port, during a write cycle.
3. Read-Before-Write – when new data is being written, the old content of the address appears at the output.
Memory Core Reset
The memory array in the EBR utilizes latches at the A and B output ports. These latches can be reset asynchronously or synchronously. RSTA and RSTB are local signals, which reset the output latches associated with Port A
and Port B respectively. The Global Reset (GSRN) signal resets both ports. The output data latches and associated
resets for both ports are as shown in Figure 2-16.

sysDSP Block
The LatticeECP-DSP family provides a sysDSP block making it ideally suited for low cost, high performance Digital
Signal Processing (DSP) applications. Typical functions used in these applications are Finite Impulse Response
(FIR) filters; Fast Fourier Transforms (FFT) functions, correlators, Reed-Solomon/Turbo/Convolution encoders and
decoders. These complex signal processing functions use similar building blocks such as multiply-adders and multiply-accumulators.
sysDSP Block Approach Compare to General DSP
Conventional general-purpose DSP chips typically contain one to four (Multiply and Accumulate) MAC units with
fixed data-width multipliers; this leads to limited parallelism and limited throughput. Their throughput is increased by
higher clock speeds. The LatticeECP, on the other hand, has many DSP blocks that support different data-widths.
This allows the designer to use highly parallel implementations of DSP functions. The designer can optimize the
DSP performance vs. area by choosing appropriate level of parallelism. Figure 2-17 compares the serial and the
parallel implementations.

sysDSP Block Capabilities
The sysDSP block in the LatticeECP-DSP family supports four functional elements in three 9, 18 and 36 data path
widths. The user selects a function element for a DSP block and then selects the width and type (signed/unsigned)
of its operands. The operands in the LatticeECP-DSP family sysDSP Blocks can be either signed or unsigned but
not mixed within a function element. Similarly, the operand widths cannot be mixed within a block.
The resources in each sysDSP block can be configured to support the following four elements:
•
•
•
•
MULT
MAC
MULTADD
MULTADDSUM
(Multiply)
(Multiply, Accumulate)
(Multiply, Addition/Subtraction)
(Multiply, Addition/Subtraction, Accumulate)
The number of elements available in each block depends in the width selected from the three available options x9,
x18, and x36. A number of these elements are concatenated for highly parallel implementations of DSP functions.
Table 2-1 shows the capabilities of the block.

Some options are available in four elements. The input register in all the elements can be directly loaded or can be
loaded as shift register from previous operand registers. In addition by selecting ‘dynamic operation’ in the ‘Signed/
Unsigned’ options the operands can be switched between signed and unsigned on every cycle. Similarly by selecting ‘Dynamic operation’ in the ‘Add/Sub’ option the Accumulator can be switched between addition and subtraction
on every cycle.

Clock, Clock Enable and Reset Resources
Global Clock, Clock Enable and Reset signals from routing are available to every DSP block. Four Clock, Reset
and Clock Enable signals are selected for the sysDSP block. From four clock sources (CLK0, CLK1, CLK2, CLK3)
one clock is selected for each input register, pipeline register and output register. Similarly Clock enable (CE) and
Reset (RST) are selected from their four respective sources (CE0, CE1, CE2, CE3 and RST0, RST1, RST2, RST3)
at each input register, pipeline register and output register.
Signed and Unsigned with Different Widths
The DSP block supports different widths of signed and unsigned multipliers besides x9, x18 and x36 widths. For
unsigned operands, unused upper data bits should be filled to create a valid x9, x18 or x36 operand. For signed
two’s complement operands, sign extension of the most significant bit should be performed until x9, x18 or x36
width is reached. Table 2-8 provides an example of this.

OVERFLOW Flag from MAC
The sysDSP block provides an overflow output to indicate that the accumulator has overflowed. When two
unsigned numbers are added and the result is a smaller number then accumulator roll over is said to occur and
overflow signal is indicated. When two positive numbers are added with a negative sum and when two negative
numbers are added with a positive sum, then the accumulator “roll-over” is said to have occurred and an overflow
signal is indicated. Note when overflow occurs the overflow flag is present for only one cycle. By counting these
overflow pulses in FPGA logic, larger accumulators can be constructed. The conditions overflow signal for signed
and unsigned operands are listed in Figure 2-22.

Two adjacent PIOs can be joined to provide a differential I/O pair (labeled as “T” and “C”) as shown in Figure 2-24.
The PAD Labels “T” and “C” distinguish the two PIOs. Only the PIO pairs on the left and right edges of the device
can be configured as LVDS transmit/receive pairs.
One of every 16 PIOs contains a delay element to facilitate the generation of DQS signals. The DQS signal feeds
the DQS bus which spans the set of 16 PIOs. Figure 2-24 shows the assignment of DQS pins in each set of 16
PIOs. The exact DQS pins are shown in a dual function in the Logic Signal Connections table at the end of this data
sheet. Additional detail is provided in the Signal Descriptions table at the end of this data sheet. The DQS signal
from the bus is used to strobe the DDR data from the memory into input register blocks. This interface is designed
for memories that support one DQS strobe per eight bits of data.

The PIO contains four blocks: an input register block, output register block, tristate register block and a control logic
block. These blocks contain registers for both single data rate (SDR) and double data rate (DDR) operation along
with the necessary clock and selection logic. Programmable delay lines used to shift incoming clock and data signals are also included in these blocks.

LatticeECP/EC Family Data Sheet
Lattice Semiconductor
Input Register Block
The input register block contains delay elements and registers that can be used to condition signals before they are
passed to the device core. Figure 2-25 shows the diagram of the input register block.
Input signals are fed from the sysIO buffer to the input register block (as signal DI). If desired the input signal can
bypass the register and delay elements and be used directly as a combinatorial signal (INDD), a clock (INCK) and
in selected blocks the input to the DQS delay block. If one of the bypass options is not chosen, the signal first
passes through an optional delay block. This delay, if selected, reduces input-register hold-time requirement when
using a global clock.
The input block allows two modes of operation. In the single data rate (SDR) the data is registered, by one of the
registers in the single data rate sync register block, with the system clock. In the DDR Mode two registers are used
to sample the data on the positive and negative edges of the DQS signal creating two data streams, D0 and D2.
These two data streams are synchronized with the system clock before entering the core. Further discussion on
this topic is in the DDR Memory section of this data sheet.
Figure 2-26 shows the input register waveforms for DDR operation and Figure 2-27 shows the design tool primitives. The SDR/SYNC registers have reset and clock enable available.
The signal DDRCLKPOL controls the polarity of the clock used in the synchronization registers. It ensures adequate timing when data is transferred from the DQS to system clock domain. For further discussion on this topic,
see the DDR Memory section of this data sheet.

Output Register Block
The output register block provides the ability to register signals from the core of the device before they are passed
to the sysIO buffers. The block contains a register for SDR operation that is combined with an additional latch for
DDR operation. Figure 2-28 shows the diagram of the Output Register Block.
In SDR mode, ONEG0 feeds one of the flip-flops that then feeds the output. The flip-flop can be configured a Dtype or latch. In DDR mode, ONEG0 is fed into one register on the positive edge of the clock and OPOS0 is
latched. A multiplexer running off the same clock selects the correct register for feeding to the output (D0).
Figure 2-29 shows the design tool DDR primitives. The SDR output register has reset and clock enable available.
The additional register for DDR operation does not have reset or clock enable available.

In SDR mode, ONEG1 feeds one of the flip-flops that then feeds the output. The flip-flop can be configured a Dtype or latch. In DDR mode, ONEG1 is fed into one register on the positive edge of the clock and OPOS1 is
latched. A multiplexer running off the same clock selects the correct register for feeding to the output (D0).

Control Logic Block
The control logic block allows the selection and modification of control signals for use in the PIO block. A clock is
selected from one of the clock signals provided from the general purpose routing and a DQS signal provided from
the programmable DQS pin. The clock can optionally be inverted.
The clock enable and local reset signals are selected from the routing and optionally inverted. The global tristate
signal is passed through this block.
DDR Memory Support
Implementing high performance DDR memory interfaces requires dedicated DDR register structures in the input
(for read operations) and in the output (for write operations). As indicated in the PIO Logic section, the EC devices
provide this capability. In addition to these registers, the EC devices contain two elements to simplify the design of
input structures for read operations: the DQS delay block and polarity control logic.
DLL Calibrated DQS Delay Block
Source Synchronous interfaces generally require the input clock to be adjusted in order to correctly capture data at
the input register. For most interfaces a PLL is used for this adjustment, however in DDR memories the clock
(referred to as DQS) is not free running so this approach cannot be used. The DQS Delay block provides the
required clock alignment for DDR memory interfaces.
The DQS signal (selected PIOs only) feeds from the PAD through a DQS delay element to a dedicated DQS routing resource. The DQS signal also feeds polarity control logic which controls the polarity of the clock to the sync
registers in the input register blocks. Figures 2-31 and 2-32 show how the DQS transition signals are routed to the
PIOs.
The temperature, voltage and process variations of the DQS delay block are compensated by a set of calibration
(6-bit bus) signals from two DLLs on opposite sides of the device. Each DLL compensates DQS Delays in its half of

Polarity Control Logic
In a typical DDR Memory interface design, the phase relation between the incoming delayed DQS strobe and the
internal system Clock (during the READ cycle) is unknown.
The LatticeECP/EC family contains dedicated circuits to transfer data between these domains. To prevent setup
and hold violations at the domain transfer between DQS (delayed) and the system Clock a clock polarity selector is
used. This changes the edge on which the data is registered in the synchronizing registers in the input register
block. This requires evaluation at the start of each READ cycle for the correct clock polarity.
Prior to the READ operation in DDR memories DQS is in tristate (pulled by termination). The DDR memory device
drives DQS low at the start of the preamble state. A dedicated circuit detects this transition. This signal is used to
control the polarity of the clock to the synchronizing registers.
sysIO Buffer
Each I/O is associated with a flexible buffer referred to as a sysIO buffer. These buffers are arranged around the
periphery of the device in eight groups referred to as Banks. The sysIO buffers allow users to implement the wide
variety of standards that are found in today’s systems including LVCMOS, SSTL, HSTL, LVDS and LVPECL.
sysIO Buffer Banks
LatticeECP/EC devices have eight sysIO buffer banks; each is capable of supporting multiple I/O standards. Each
sysIO bank has its own I/O supply voltage (VCCIO), and two voltage references VREF1 and VREF2 resources allowing each bank to be completely independent from each other. Figure 2-33 shows the eight banks and their associated supplies.
In the LatticeECP/EC devices, single-ended output buffers and ratioed input buffers (LVTTL, LVCMOS, PCI and PCIX) are powered using VCCIO. LVTTL, LVCMOS33, LVCMOS25 and LVCMOS12 can also be set as fixed threshold
input independent of VCCIO. In addition to the bank VCCIO supplies, the LatticeECP/EC devices have a VCC core logic
power supply, and a VCCAUX supply that power all differential and referenced buffers.
Each bank can support up to two separate VREF voltages, VREF1 and VREF2 that set the threshold for the referenced input buffers. In the LatticeECP/EC devices, some dedicated I/O pins in a bank can be configured to be a
reference voltage supply pin. Each I/O is individually configurable based on the bank’s supply and reference voltages.

LatticeECP/EC devices contain two types of sysIO buffer pairs.
1. Top and Bottom sysIO Buffer Pair (Single-Ended Outputs Only)
The sysIO buffer pairs in the top and bottom banks of the device consist of two single-ended output drivers and
two sets of single-ended input buffers (both ratioed and referenced). The referenced input buffer can also be
configured as a differential input.
The two pads in the pair are described as “true” and “comp”, where the true pad is associated with the positive
side of the differential input buffer and the comp (complementary) pad is associated with the negative side of
the differential input buffer.
Only the I/Os on the top and bottom banks have PCI clamp.
2. Left and Right sysIO Buffer Pair (Differential and Single-Ended Outputs)
The sysIO buffer pairs in the left and right banks of the device consist of two single-ended output drivers, two
sets of single-ended input buffers (both ratioed and referenced) and one differential output driver. The referenced input buffer can also be configured as a differential input. In these banks the two pads in the pair are
described as “true” and “comp”, where the true pad is associated with the positive side of the differential I/O,
and the comp (complementary) pad is associated with the negative side of the differential I/O.
Only the left and right banks have LVDS differential output drivers.
Supported Standards
The LatticeECP/EC sysIO buffer supports both single-ended and differential standards. Single-ended standards
can be further subdivided into LVCMOS, LVTTL and other standards. The buffers support the LVTTL, LVCMOS 1.2,
1.5, 1.8, 2.5 and 3.3V standards. In the LVCMOS and LVTTL modes, the buffer has individually configurable

options for drive strength, bus maintenance (weak pull-up, weak pull-down, or a bus-keeper latch) and open drain.
Other single-ended standards supported include SSTL and HSTL. Differential standards supported include LVDS,
BLVDS, LVPECL, RSDS, differential SSTL and differential HSTL. Tables 2-13 and 2-14 show the I/O standards
(together with their supply and reference voltages) supported by the LatticeECP/EC devices. For further information on utilizing the sysIO buffer to support a variety of standards please see the details of additional technical information at the end of this data sheet.

Hot Socketing
The LatticeECP/EC devices have been carefully designed to ensure predictable behavior during power-up and
power-down. Power supplies can be sequenced in any order. During power up and power-down sequences, the
I/Os remain in tristate until the power supply voltage is high enough to ensure reliable operation. In addition,
leakage into I/O pins is controlled to within specified limits, this allows for easy integration with the rest of the
system. These capabilities make the LatticeECP/EC ideal for many multiple power supply and hot-swap applications.
Recommended Power Up Sequence: As described in the previous paragraph, the supplies can be sequenced
in any order. However, once internal power good is achieved (determined by VCC, VCCAUX, VCCIO bank 5) the
part releases I/Os from tri-state and the management of I/Os becomes the designers responsibility. To simplify a
system design it is therefore recommended that supplies be sequenced VCCIO, VCC, VCCAUX.

Configuration and Testing
The following section describes the configuration and testing features of the LatticeECP/EC family of devices.
IEEE 1149.1-Compliant Boundary Scan Testability
All LatticeECP/EC devices have boundary scan cells that are accessed through an IEEE 1149.1 compliant test
access port (TAP). This allows functional testing of the circuit board, on which the device is mounted, through a
serial scan path that can access all critical logic nodes. Internal registers are linked internally, allowing test data to
be shifted in and loaded directly onto test nodes, or test data to be captured and shifted out for verification. The test
access port consists of dedicated I/Os: TDI, TDO, TCK and TMS. The test access port has its own supply voltage
VCCJ and can operate with LVCMOS3.3, 2.5, 1.8, 1.5 and 1.2 standards.
For more details on boundary scan test, please see information regarding additional technical documentation at
the end of this data sheet.
Device Configuration
All LatticeECP/EC devices contain two possible ports that can be used for device configuration. The test access
port (TAP), which supports bit-wide configuration, and the sysCONFIG port that supports both byte-wide and serial
configuration.
The TAP supports both the IEEE Std. 1149.1 Boundary Scan specification and the IEEE Std. 1532 In-System Configuration specification. The sysCONFIG port is a 20-pin interface with six of the I/Os used as dedicated pins and
the rest being dual-use pins. When sysCONFIG mode is not used, these dual-use pins are available for general
purpose I/O. There are four configuration options for LatticeECP/EC devices:
1. Industry standard SPI memories.
2. Industry standard byte wide flash and ispMACH 4000 for control/addressing.
3. Configuration from system microprocessor via the configuration bus or TAP.
4. Industry standard FPGA board memory.
On power-up, the FPGA SRAM is ready to be configured with the sysCONFIG port active. The IEEE 1149.1 serial
mode can be activated any time after power-up by sending the appropriate command through the TAP port. Once a
configuration port is selected, that port is locked and another configuration port cannot be activated until the next
power-up sequence.
For more information on device configuration, please see details of additional technical documentation at the end
of this data sheet.
Internal Logic Analyzer Capability (ispTRACY)
All LatticeECP/EC devices support an internal logic analyzer diagnostic feature. The diagnostic features provide
capabilities similar to an external logic analyzer, such as programmable event and trigger condition and deep trace
memory. This feature is enabled by Lattice’s ispTRACY. The ispTRACY utility is added into the user design at compile time.
For more information on ispTRACY, please see information regarding additional technical documentation at the
end of this data sheet.
External Resistor
LatticeECP/EC devices require a single external, 10K ohm +/- 1% value between the XRES pin and ground.
Device configuration will not be completed if this resistor is missing. There is no boundary scan register on the
external resistor pad.
2-32
Architecture
LatticeECP/EC Family Data Sheet
Lattice Semiconductor
Oscillator
Every LatticeECP/EC device has an internal CMOS oscillator which is used to derive a master serial clock for configuration. The oscillator and the master serial clock run continuously. The default value of the master serial clock is
2.5MHz. Table 2-15 lists all the available Master Serial Clock frequencies. When a different Master Serial Clock is
selected during the design process, the following sequence takes place:
1. User selects a different Master Serial Clock frequency.
2. During configuration the device starts with the default (2.5MHz) Master Serial Clock frequency.
3. The clock configuration settings are contained in the early configuration bit stream.
4. The Master Serial Clock frequency changes to the selected frequency once the clock configuration bits are
received.
For further information on the use of this oscillator for configuration, please see details of additional technical documentation at the end of this data sheet.

Density Shifting
The LatticeECP/EC family has been designed to ensure that different density devices in the same package have
the same pin-out. Furthermore, the architecture ensures a high success rate when performing design migration
from lower density parts to higher density parts. In many cases, it is also possible to shift a lower utilization design
targeted for a high-density device to a lower density device. However, the exact details of the final resource utilization will impact the likely success in each case.

Derating Timing Tables
Logic Timing provided in the following sections of the data sheet and the ispLEVER design tools are worst-case
numbers in the operating range. Actual delays at nominal temperature and voltage for best-case process, can be
much better than the values given in the tables. To calculate logic timing numbers at a particular temperature and
voltage multiply the noted numbers with the derating factors provided below.
The junction temperature for the FPGA depends on the power dissipation by the device, the package thermal characteristics (ΘJA), and the ambient temperature, as calculated with the following equation:
TJMAX = TAMAX + (Power * ΘJA)
The user must determine this temperature and then use it to determine the derating factor based on the following
derating tables: TJ °C.

[Edge] indicates the edge of the device on which the pad is located. Valid
edge designations are L (Left), B (Bottom), R (Right), T (Top).
[Row/Column Number] indicates the PFU row or the column of the device on
which the PIC exists. When Edge is T (Top) or (Bottom), only need to specify
Row Number. When Edge is L (Left) or R (Right), only need to specify Column Number.

[A/B] indicates the PIO within the PIC to which the pad is connected.
Some of these user-programmable pins are shared with special function
pins. These pin when not used as special purpose pins can be programmed
as I/Os for user logic.
During configuration the user-programmable I/Os are tri-stated with an internal pull-up resistor enabled. If any pin is not used (or not bonded to a package pin), it is also tri-stated with an internal pull-up resistor enabled after
configuration.

Ordering Information
Note: LatticeECP/EC devices are dual marked. For example, the commercial speed grade LFEC20E-4F484C is
also marked with industrial grade -3I (LFEC20E-3F484I). The commercial grade is one speed grade faster than the
associated dual mark industrial grade. The slowest commercial speed grade does not have industrial markings.
The markings appear as follows:
