GENERAL DESCRIPTION
The WS57C256F is a High Performance 32K x 8 UV Erasable EPROM. It is manufactured using an advanced CMOS process technology enabling it to operate at speeds as fast as 35 ns Address Access Time (tACC) and 35 ns Chip Enable Time (tCE). It was designed utilizing WSIs patented self-aligned split gate EPROM cell, resulting in a low power device with a very cost effective die size. The low standby power capability of this 256 K product (200 µA in a CMOS interface environment) is especially attractive.
