GENERAL DESCRIPTION
The WS57C51C is a High Performance 128K 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.
A further advantage of the WS57C51C over Bipolar PROM devices is the fact that it utilizes a proven EPROM
technology. This enables the entire memory array to be tested for switching characteristics and functionality after
assembly. Unlike devices which cannot be erased, every WS5751C in a windowed package is 100% tested with
worst case test patterns both before and after assembly.
The WS57C51C provides a low power alternative to those designs which are committed to a Bipolar PROM
footprint. It is a direct drop-in replacement for a Bipolar PROM of the same architecture (16K x 8). No software,
hardware or layout changes need be performed.
