The 70V37 is a high-speed 32K x 18 Dual-Port Static RAM designed to be used as a stand-alone 576K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit or more word systems. This MASTER/SLAVE approach in 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. 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.

特長

  • Dual-Ported allows simultaneous access of the same memory location
  • Dual chip enables allow for depth expansion without external logic
  • Easily expands data bus width to 36 bits or more
  • Busy and Interrupt Flags
  • On-chip port arbitration logic
  • Full on-chip hardware support of semaphore signaling between ports
  • Fully asynchronous operation from either port
  • Separate upper-byte and lower-byte controls for multiplexed bus and bus matching compatibility
  • LVTTL-compatible, single 3.3V (±0.3V) power supply
  • Available in a 100-pin TQFP package
  • Industrial temperature range (–40C to +85C) is available
