AT94S Secure Family

2314D–FPSLI–2/04

Description

The AT94S Series (Secure FPSLIC family) shown in Table 1 is a combination of the

popular Atmel AT40K Series SRAM FPGAs, the AT17 Series Configuration Memories

and the high-performance Atmel AVR 8-bit RISC microcontroller with standard peripher-

als. Extensive data and instruction SRAM as well as device control and management

logic are included in this multi-chip module (MCM).

The embedded 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.
