AT94K Series FPSLIC
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.

1. FPSLIC parts with JTAG ICE support can be identified by the letter “J” after the device date
2. FPSLIC devices should be laid out during PCB design to support a split power supply.
code, e.g., 4201 (no ICE support) and 4201J (with ICE support), see Figure 1.
