Introduction
The Xilinx Automotive (XA) Spartan-IIE 1.8V Field-Pro-
grammable Gate Array family is specifically designed to
meet the needs of high-volume, cost-sensitive automotive
electronic applications. The family gives users high perfor-
mance, abundant logic resources, and a rich feature set, all
at an exceptionally low price. The five-member family offers
densities ranging from 50,000 to 300,000 system gates, as
shown in
Table 1. System performance is supported beyond
200 MHz.
Spartan-IIE devices deliver more gates, I/Os, and features
per dollar than other FPGAs by combining advanced pro-
cess technology with a streamlined architecture based on
the proven Virtex-E platform. Features include block RAM
(to 64K bits), distributed RAM (to 98,304 bits), 19 selectable
I/O standards, and four DLLs (Delay-Locked Loops). Fast,
predictable interconnect means that successive design iter-
ations continue to meet timing requirements.
XA devices are available in both the extended-temperature
Q-grade (-40°C to +125°C) and industrial I-grade (-40°C to
+100°C) and are qualified to the industry-recognized
AEC-Q100 standard.
The XA Spartan-IIE family is a superior alternative to
mask-programmed ASICs. The FPGA avoids the initial cost,
lengthy development cycles, and inherent risk of conven-
tional ASICs. Also, FPGA programmability permits design
upgrades in the field with no hardware replacement neces-
sary (impossible with ASICs).
