GENERAL DESCRIPTION

The WS57C191C/291C is an extremely High Performance 16K UV Erasable Electrically Re-Programmable Read Only Memory (RPROM). It is manufactured in an advanced CMOS technology which enables it to operate at Bipolar PROM speeds while consuming only 25 of the power required by its Bipolar counterparts. The WS57C191C/291C is also configured in the standard Bipolar PROM pinout which provides an easy upgrade path for systems which are currently using Bipolar PROMs. The WS57C191C is packaged in a conventional 600 mil DIP package as well as a Plastic Leaded Chip Carrier (PLDCC) and a Ceramic Leadless Chip Carrier (CLLCC).

The WS57C291C is packaged in a space saving 300 mil DIP package configuration. Both are available in commercial, industrial, and military operating temperature ranges.
