71V321规格书详情
描述 Description
The 71V321 is a high-speed 2K x 8 Dual-Port Static RAMs with internal interrupt logic for interprocessor communications.The device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. 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
On-chip port arbitration logic
BUSY output flag
Fully asynchronous operation from either port
Battery backup operation—2V data retention (L only)
TTL-compatible, single 3.3V power supply
Available in 52-pin PLCC, 64-pin TQFP and STQFP packages
Industrial temperature range (–40C to +85C) is available
