FPGAs to meet the certification requirements of the AEC-Q100 standard
Lattice Semiconductor announced that automotive versions of its
non-volatile 90nm Flash-based LatticeXP2 FPGAs (Field Programmable Gate
Array) have been characterized and qualified to meet the certification
requirements of the AEC-Q100 standard as defined by the Automotive
Electronics Council (AEC). Designated the LA (“Lattice
Automotive”)-LatticeXP2 family, these production released devices
join Lattice's four previously announced automotive LA versions of the
MachXOÔ Crossover Programmable Logic Devices,
ispPAC®-POWR1014/A Programmable Power Manager Devices, ispMACH®
4000V and ispMACH 4000Z CPLDs. Production quantities of the new
LA-LatticeXP2 devices will be available by the fourth quarter of 2008,
and Lattice can provide standard PPAP (Production Part Approval
Process) documentation now to automotive customers who require it.
An Expanding Commitment to the Automotive Market
“The automotive market’s appetite for programmable logic
solutions continues to grow rapidly. Lattice has provided
commercial, industrial and automotive grade programmable logic products
to the automotive industry for many years, and our programmable devices
are used in many applications, ranging from Engine Control Units to
Network Gateways, Video Camera Systems, Telematics and Digital
Radio,” said Stan Kopec, corporate vice president of
marketing. "The LA-LatticeXP2 devices, with Flash boot memory and
FPGA blocks integrated into a single die, are uniquely suited for
‘instant-on’ automotive systems, and can be reprogrammed in
the vehicle (‘in-system’) for easy feature upgrades.
Reliability-conscious customers will appreciate unique LA-LatticeXP2
features such as “golden configuration” boot redundancy and
continuous SRAM scanning and recovery. Our Lattice Automotive
products, and our initiative to certify our quality systems to the
ISO/TS-16949 standard, demonstrate our ongoing and expanding commitment
to serve our customers in the automotive industry.”
About LA-LatticeXP2 Devices
The LA-LatticeXP2 automotive FPGA family includes three members, with
capacities from 5K to 17K 4-input Look Up Tables (LUTs). Embedded
Block RAM is provided with up to 276Kbits on-chip in 18Kbit dual-port
blocks. For small scratch pad memories, LUTs also can be
converted into small, distributed memory blocks. To support
increasingly common DSP applications, up to 5 sysDSP™ blocks
provide hardwired, high-performance pipelined multiply and accumulate
functions. The devices have up to four Phase Locked Loops (PLLs)
that allow designers to align and synthesize clocks as required in
their designs.
Recognizing that power consumption is a critical concern for system
designers, Lattice designed the LA-LatticeXP2 family to use a 1.2-volt
core voltage for low power consumption. I/O capacities for the
family range from 86 to 358 pins. Flexible I/O buffers support
the most popular I/O standards, including LVCMOS, SSTL, HSTL and
LVDS. These buffers are supported by pre-engineered I/O logic
that simplifies the implementation of Double Data Rate (DDR) and source
synchronous standards. This combination provides support for DDR2
memory interfaces at 400Mbps, high performance ADC/DACs at up to
750Mbps and 7:1 LVDS display interfaces at above 600Mbps.
LA-LatticeXP2 devices are available in thin Fine Pitch Ball Grid Array
(ftBGA) packages as well as popular TQFP and PQFP options.
flexiFLASH Architecture Enables Enhanced Non-Volatile Single Chip Solution
Flash memory blocks are embedded within LA-LatticeXP2 FPGAs to store
the device configuration, providing a true single chip solution that
Lattice calls the flexiFLASH™ architecture. At power up or
on user command, the data stored in the Flash memory is transferred
into SRAM cells that control the configuration of the device.
This transfer is done in a massively parallel fashion, enabling the
device logic to be available in approximately 1mS, well ahead of the
other devices in the system and much faster than SRAM-based FPGAs that
use external boot PROMs, regardless of whether they are provisioned
separately on-board or stacked in the same package. This
instant-on capability is critical for many system functions such as
power up sequencing, address decoding and reset logic.
By keeping the configuration bitstream on-chip, the LA-LatticeXP2
devices also are inherently more secure than alternative multiple
device or multi-chip module solutions. This security is enhanced
by configuration read-back protection modes. A 64-bit
erase/program lock protects against accidental or unauthorized device
programming. A one time programmable (OTP) mode is provided for
ultimate protection against unauthorized programming. Optional
128-bit AES encryption can be used to secure programming data being
passed into the device.
The devices also support up to 276Kbits of FlashBAK™
memory. This exclusive capability allows Embedded Block RAMs to
be initialized at power up from Flash memory. During device
operation, designers also can choose to write updated data from the
block RAM back into the Flash memory. This provides a method to
store data such as Power On Self Test (POST), microprocessor code and
calibration data. An additional 0.6 to 2.2Kbits of Flash memory
is provided in the form of Serial TAG memory for general-purpose use by
system designers for storage of device revision data, board identifiers
and other data.
Samples of the LA-LatticeXP2 family 5K and 8K LUT devices in 144 TQFP
and 256ftBGA, and of the 17K LUT device in the 256ftBGA package, are
available now, with 208-PQFP package options available in the third
quarter of 2008.
