Summary
The Xilinx® Automotive (XA) Spartan®-3E family of FPGAs
is specifically designed to meet the needs of high-volume,
cost-sensitive automotive electronics applications. The
five-member family offers densities ranging from 100,000 to
1.6 million system gates, as shown in Table 1.
-
-
Enhanced Double Data Rate (DDR) support
DDR SDRAM support up to 266 Mb/s
•
Abundant, flexible logic resources
-
Densities up to 33,192 logic cells, including
optional shift register or distributed RAM support
Efficient wide multiplexers, wide logic
Fast look-ahead carry logic
Enhanced 18 x 18 multipliers with optional pipeline

Introduction
XA devices are available in both extended-temperature
Q-Grade (–40°C to +125°C T ) and I-Grade (–40°C to
J
+100°C T ) and are qualified to the industry recognized
J
•
•
Hierarchical SelectRAM™ memory architecture
-
-
AEC-Q100 standard.
Up to 648 Kbits of fast block RAM
Up to 231 Kbits of efficient distributed RAM
The XA Spartan-3E family builds on the success of the ear-
lier XA Spartan-3 family by increasing the amount of logic
per I/O, significantly reducing the cost per logic cell. New
features improve system performance and reduce the cost
of configuration. These XA Spartan-3E FPGA enhance-
ments, combined with advanced 90 nm process technology,
deliver more functionality and bandwidth per dollar than was
previously possible, setting new standards in the program-
mable logic industry.
Up to eight Digital Clock Managers (DCMs)
-
-
-
-
Clock skew elimination (delay locked loop)
Frequency synthesis, multiplication, division
High-resolution phase shifting
Wide frequency range (5 MHz to over 300 MHz)
•
•
Eight global clocks plus eight additional clocks per
each half of device, plus abundant low-skew routing
Configuration interface to industry-standard PROMs
-
-
Complete Xilinx ISE® and WebPACK™ software
support
MicroBlaze™ and PicoBlaze™ embedded processor
cores
Because of their exceptionally low cost, XA Spartan-3E
FPGAs are ideally suited to a wide range of automotive
applications, including infotainment, driver information, and
driver assistance modules.
Low-cost, space-saving SPI serial Flash PROM
x8 or x8/x16 parallel NOR Flash PROM

The XA Spartan-3E family is a superior alternative to mask
programmed ASICs and ASSPs. FPGAs avoid the high ini-
tial mask set costs and lengthy development cycles, while
also permitting design upgrades in the field with no hard-
ware replacement necessary because of its inherent pro-
grammability, an impossibility with conventional ASICs and
ASSPs with their inflexible hardware architecture.
Fully compliant 32-/64-bit 33 MHz PCI™ technology
support
Low-cost QFP and BGA packaging options
-
Common footprints support easy density migration
