WS57C191C/291C  
HIGH SPEED 2K x 8 CMOS PROM/RPROM  
KEY FEATURES  
• Ultra-Fast Access Time  
• Pin Compatible with Am27S191/291  
and N82S191 Bipolar PROMs  
— t  
= 25 ns  
ACC  
— t  
= 12 ns  
CS  
• Immune to Latch-UP  
• Low Power Consumption  
• Fast Programming  
— Up to 200 mA  
• ESD Protection Exceeds 2000V  
• Available in 300 Mil DIP and PLDCC  
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.
