M87C257 ADDRESS LATCHED 256K 32K x 8 UV EPROM and OTP EPROM

M87C257 Description

M87C257 ADDRESS LATCHED 256K (32K x 8) UV EPROM and OTP EPROM INTEGRATED ADDRESS LATCH FAST ACCESS TIME: 45ns LOW POWER “CMOS” CONSUMPTION: * .
The M87C257 is a high speed 262,144 bit UV erasable and electrically programmable EPROM.

M87C257 Features

* a 2 line control function which accommodates the use of multiple memory connection. The two line control function allows: a. the lowest possible memory power dissipation, b. complete assurance that output bus contention will not occur. For the most efficient use of these two control lines, E should

M87C257 Applications

* where the content is programmed only one time and erasure is not required, the M87C257 is offered in Plastic Leaded Chip Carrier, package. VCC 15 A0-A14 8 Q0-Q7 E G M87C257 Table 1. Signal Names A0 - A14 Q0 - Q7 E G ASVPP VCC VSS Address Inputs Data Outputs Chip Enable Output Enable Address St
