描述
The 71V30 high-speed 1K x 8 dual-port static RAM is designed to be used as a stand-alone 8-bit dual-port SRAM. It has 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
- True dual-ported memory cells allow simultaneous access of the same memory location
- On-chip port arbitration logic
- Interrupt flags for port-to-port communication
- Fully asynchronous operation from either port
- Battery backup operation, 2V data retention (L only)
- TTL-compatible, single 3.3V ±0.3V power supply
- Available in a 64-pin STQFP package
- Industrial temperature range (–40 °C to +85 °C) is available
