描述 Description

The 71421 is a high-speed 2K x 8 Dual-Port Static RAM with internal interrupt logic for interprocessor communications. It is designed to be used as a \"SLAVE\" Dual-Port RAM together with the 71321 \"MASTER\" Dual-Port in 16-bit-or-more word width systems which would result in full-speed, error free operation without the need for additional discrete logic. An automatic power down feature, controlled by CE, permits the on chip circuitry of each port to enter a very low standby power mode.

特性 Features

True Dual-Ported memory cells which allow simultaneous access of the same memory location
Two INT flags for port-to-port communications
BUSY input
Fully asynchronous operation from either port
Battery backup operation – 2V data retention (LA only)
TTL-compatible, single 5V ±10% power supply
Available in 52-Pin PLCC, 64-Pin TQFP and STQFP packages
Industrial temperature range (–40C to +85C) is available
