Description
MILITARY HIGH SPEED 2K x 8 CMOS PROM/RPROM
Manufacturer
STMICROELECTRONICS [STMicroelectronics]
Datasheet
MODE SELECTION
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. The WS57C291C is packaged in a space
saving 300 mil DIP package configuration.
