特長
- True dual-ported memory cells, which allow simultaneous reads of the same memory location
- Separate upper-byte and lower-byte control for multiplexed bus compatibility
- 5962-91662 easily expands data bus width to 32 bits or more
- Interrupt flag and on-chip port arbitration logic
- Full on-chip hardware support of semaphore signaling between ports
- Fully asynchronous operation from either port
- Battery backup operation - 2V data retention
- TTL-compatible, single 5V (±10%) power supply
- Available in 84-pin ceramic PGA and Flatpack packages
説明
The 5962-91662 (7024) is a high-speed 4K x 16 dual-port static RAM designed to be used as a stand-alone 64K-bit dual-port RAM or as a combination Master/Slave dual-port RAM for 32-bit or more word systems. An automatic power-down feature controlled by the Chip Enable (CE) permits the on-chip circuitry of each port to enter a very low standby power mode. The military-grade product complies with MIL-PRF-38535 QML.
