Description

The Atmel “750” architecture is twice as powerful as most other 24-pin programmable

logic devices. Increased product terms, sum terms, flip-flops and output logic configu-

rations translate into more usable gates. High-speed logic and uniform, predictable

delays guarantee fast in-system performance. The ATF750LVC is a high-performance
