| WS57C51C MILITARY HIGH SPEED 16K x 8 CMOS PROM/RPROM KEY FEATURES * Ultra-Fast Access Time -- 45 ns * Pin Compatible with Am27S51 and N82HS1281 * Immune to Latch-Up -- Up to 200 mA * Low Power Consumption * Fast Programming * ESD Protection Exceeds 2000 V 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.
