AT94K Series FPSLIC

Rev. 1138F–FPSLI–06/02

Description

The AT94K Series FPSLIC family shown in Table 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.

2. FPSLIC devices should be laid out during PCB design to support a split power supply.
