BLOCK DIAGRAM
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.
