GENERAL DESCRIPTIONThe 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.
