The SRAM-based 0.6 µm and 0.55 µm ATT3000 Series FPGAs, which feature toggle rates up to 270 MHz, are a direct second source to the Xilinx XC3000 FPGAs and are pin-for-pin and speed compatible with the Xilinx XC3100 FPGAs.
The ATT3000 regular, flexible, reprogrammable array architecture is composed of a configuration program store with three types of configurable elements: a perimeter of input/output blocks (IOBs), a core array of configurable logic blocks (CLBs), and ample resources for interconnection.
The CLB implements logic functions by using programmed look-up tables (LUTs). Functional options are implemented by user programmable multiplexers. Interconnecting networks are implemented with metal routing lines joined by user programmable pass transistors. Registers or flip-flops are found in CLBs and IOBs.
The devices are customized by a configuration program stored in internal SRAM-based memory cells. The program data resides externally from the FPGAs in an EEPROM, EPROM, or ROM on the circuit board, or on a floppy or hard disk.
