iFX780

The iFX780 is the first member of the intel FLEXlog-ic FPGA(field programmable gate array) family.The iFX780 consists of eight configurable function blocks(CFBs) linked by a 100% connectable matrix.Each CFB can be defined either as a 24V10 logic block or as a block of 128X10 SRAM.This combination will provide approximately 5,000 gates of logic in either PLCC or PQFP packages.

The flexible features of iFX780 are:the unique combination of features available in the iFX780 make it ideal for a wide variety of applications.For example,the high pertormance and flexible clock options provided are designed to support functions such as bus control,custom cache control,and DRAM control for the current and next generation of intel microprocessors.The very low power consumption and user selectable 5V/3.3V still need to communicate to 5V peripherals.The combination of SRAM and logic in a single device becomes a big advantage when designing communication controllers or bus interface comtrollers where memory is required for buffering data in addition to the logic for the controller design itself.

Here are the absolute maximum ratings of the iFX780:(1)supply voltage:-2.0 to +7.0 V;(2)programming supply voltage:-2.0 to +13.5 V;(3)DC input voltage:-0.5 to Vcc+0.5 V;(4)storage temperature:-65 to +150°C;(5)ambient temperature:-10 to +85°C.Notes:voltages with respect to ground;minimum DC input is -0.5V,during transitions,the input may undershoot to -2.0V or +7.0V for periods less than 20 ns under no load conditions;under bias,extended temperature versions are also available.
