WS57C43

WS57C43C HIGH SPEED 4K x 8 CMOS PROM/RPROM KEY FEATURES • Ultra-Fast Access Time — t ACC = 25 ns — t CS = 12 ns • Pin Compatible with 4K x 8 Bipolar PROMs • Immune to Latch-UP — Up to 200 mA • Low Power Consumption • Fast Programming • ESD Protection Exceeds 2000 V • Available in 300 Mil DIP and PLDCC GENERAL DESCRIPTION The WS57C43C is a High Performance 32K 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 WS57C43C 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 WS5743C in a windowed package is 100% tested with worst case test patterns both before and after assembly. The WS57C43C is configured in the standard Bipolar PROM pinout which provides an easy upgrade path for systems which are currently using Bipolar PROMs, or its predecessor, the WS57C43B.

Timing measurements are made at 1.5 V for input and output transitions in both directions. NOTE: 6. Provide adequate decoupling capacitance as close as possible to this device to achieve the published A.C. and D.C. parameters. A 0.1 microfarad capacitor in parallel with a 0.01 microfarad capacitor connected between VCC and ground is recommended. Inadequate decoupling may result in access time degradation or other transient performance failures.
