Description

The AT28HC256 is a high-performance Electrically Erasable and Programmable

Read Only Memory. Its 256K of memory is organized as 32,768 words by 8 bits.

Manufactured with Atmel’s advanced nonvolatile CMOS technology, the AT28HC256

offers access times to 70 ns with power dissipation of just 440 mW. When the

AT28HC256 is deselected, the standby current is less than 5 mA.
