GENERAL DESCRIPTION
The WS57C128FB is a High Performance 128K UV Erasable Electrically Programmable Read Only Memory. It is
manufactured with an advanced CMOS technology which enables it to operate at Bipolar speeds while consuming
only 90 mA.
Two major features of the WS57C128FB are its Low Power and High Speed. These features make it an ideal
solution for applications which require fast access times, low power, and non-volatility. Typical applications include
systems which do not utilize mass storage devices and/or are board space limited.
The WS57C128FB is configured in the standard EPROM pinout which provides an easy upgrade path for systems
which are currently using standard EPROMs. The EPROMs are available in both 600 Mil DIP packages, and both
J-leaded and leadless surface mount packages.
