描述

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 the Chip Enable (CE) permits the on-chip circuitry of each port to enter a very low standby power mode.

特性

  • Dual-port 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 (–40 °C to +85 °C) is available
