A high-performance electrically erasable CMOS programmable logic device (PLD) with proven Microchip electrically erasable flash memory. The device supports speeds down to 5ns and power dissipation as low as 10??A (typical). All speed ranges are specified over the full 5V ± 10% range for military and industrial applications and 5V ± 5 percent for commercial applications. Each of several low-power options can significantly reduce total system power and enhance system reliability.
