8K x 16 Dual-Port RAM

The 7025 is a high-speed 8K x 16 Dual-Port Static RAM designed to be used as a stand-alone 128K-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.

Features

  • 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
  • 7025 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
