概要
説明
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.
特長
- 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
