GENERAL DESCRIPTION
The WS57C256F is a High Performance 256K UV Erasable Electrically Programmable
Read Only Memory. It is manufactured using an advanced CMOS process technology
enabling it to operate at speeds as fast as 55 ns Access Time.
Two major features of the WS57C256F are its Low Power and High Speed. While
operating in a TTL environment it consumes less than 120 mA while cycling at
full speed. Additionally, the WS57C256F can be placed in a standby mode which
drops operating current below 5 mA in a TTL environment and 500 µA in a CMOS
environment.
The WS57C256F also has exceptional output drive capability. It can source 4 mA
and sink 16 mA per output.
The WS57C256F is configured in the standard EPROM pinout which provides an
easy upgrade path for systems which are currently using standard EPROMs.
