- 7024 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 PGA, Flatpack, PLCC, and 100-pin TQFP packages
- Industrial temperature range (–40C to +85C) is available
Description
The 7024 is a high-speed 4Kx 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 Chip Enable (CE) permits the on-chip circuitry of each port to enter a very low standby power mode. Military grade product in compliance with MIL-PRF-38535 QML is available.
