WS57C128FB HIGH SPEED 16K x 8 CMOS EPROM
KEY FEATURES
* Very Fast Access Time
-- 35 ns
* Standard EPROM Pinout * DIP and Surface Mount Packaging
Available
* Low Power Consumption * EPI Processing
-- Latch-up Immunity Up to 200 mA
GENERAL DESCRIPTION
The WS57C128FB is a High Performance 128K UV Erasable Electrically Programmable Read Only Memory. It is manufactured with an advanced CMOS technology which enables it to operate at Bipolar speeds while consuming only 90 mA. Two major features of the WS57C128FB are its Low Power and High Speed. These features make it an ideal solution for applications which require fast access times, low power, and non-volatility. Typical applications include systems which do not utilize mass storage devices and/or are board space limited. The WS57C128FB is configured in the standard EPROM pinout which provides an easy upgrade path for systems which are currently using standard EPROMs. The EPROMs are available in both 600 Mil DIP packages, and both J-leaded and leadless surface mount packages.

A.C. testing inputs are driven at 3.0 V for a logic "1" and 0.0 V for a logic "0." Timing measurements are made at 2.0 V for a logic "1" and 0.8 V for a logic "0". NOTE: 8. 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.
