Features
Description
The AT27RW1024 is a low-power, high-performance 1,048,576-bit electrically-
rewriteable programmable read-only memory (RWPROM) organized 64K x 16 bits. It
requires only one 5V power supply in normal read mode operation. Any word can be
accessed in less than 35 ns, eliminating the need for speed reducing WAIT states.
