Introduction
-
SelectRAM+™ hierarchical memory:
The Spartan™-IIE 1.8V Field-Programmable Gate Array
family gives users high performance, 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. Sys-
tem performance is supported beyond 200 MHz.

Low-power segmented routing architecture
Full readback ability for verification/observability
Dedicated carry logic for high-speed arithmetic
Efficient multiplier support
Cascade chain for wide-input functions
Abundant registers/latches with enable, set, reset
Four dedicated DLLs for advanced clock control
Four primary low-skew global clock distribution nets
IEEE 1149.1 compatible boundary scan logic
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.
The Spartan-IIE family is a superior alternative to
mask-programmed ASICs. The FPGA avoids the initial cost,
lengthy development cycles, and inherent risk of
conventional ASICs. Also, FPGA programmability permits
design upgrades in the field with no hardware replacement
necessary (impossible with ASICs).
