AT94KAL Series FPSLIC Summary

1.

Description

The AT94KAL Series FPSLIC family shown in Table 1-1 is a combination of the popular Atmel

AT40K Series SRAM FPGAs and the high-performance Atmel AVR 8-bit RISC microcontroller

with standard peripherals. Extensive data and instruction SRAM as well as device control and

management logic are included on this monolithic device, fabricated on Atmel’s 0.35µ five-layer

metal CMOS process.

The AT40K FPGA core is a fully 3.3V PCI-compliant, SRAM-based FPGA with distributed

10 ns programmable synchronous/asynchronous, dual-port/single-port SRAM, 8 global clocks,

Cache Logic ability (partially or fully reconfigurable without loss of data) and 5,000 to 40,000

usable gates.

Notes:

1. FPSLIC parts with JTAG ICE support can be identified by the letter “J” after the device date

code, e.g., 4201 (no ICE support) and 4201J (with ICE support), see Figure 1-1.
