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.
Introduction
XA devices are available in both extended-temperature
Q-Grade (–40°C to +125°C TJ) and I-Grade (–40°C to
+100°C TJ) and are qualified to the industry recognized
AEC-Q100 standard.
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.
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.
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.
