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. BLOCK DIAGRAM EPROM ARRAY PIN CONFIGURATION TOP VIEW 6 A5 - A10 ROW ADDRESSES ROW DECODER Chip Carrier 16,384 BITS CERDIP/Plastic DIP NC A5 A 6 A 7 5 A0 - A4 COLUMN ADDRESSES COLUMN DECODER VCC A8 A9 SENSE AMPLIFIERS CS1/ VPP CS2 CS3 8 A4 A3 A2...
