Description

The AT27C800 is a low-power, high performance 8,388,608-bit UV erasable program-

mable read only memory (EPROM) organized as either 512K by 16 or 1024K by 8

bits. It requires a single 5V power supply in normal read mode operation. Any word

can be accessed in less than 100 ns, eliminating the need for speed-reducing WAIT

states. The x16 organization makes this part ideal for high-performance 16- and 32-bit
