Overview

Description

The 70T653M is a high-speed 256K x 36 Asynchronous Dual-Port Static RAM designed to be used as a stand-alone 18874K-bit Dual-Port RAM. An automatic power down feature controlled by the chip enables (either CE0 or CE1) permit the on-chip circuitry of each port to enter a very low standby power mode.

Features

  • Dual-Port allows simultaneous access of the same memory location
  • RapidWrite Mode simplifies high-speed consecutive write cycles
  • Dual chip enables allow for depth expansion without external logic
  • Easily expands data bus width to 72 bits or more using the Busy Input when cascading more than one device
  • Busy input for port contention management
  • Interrupt Flags
  • Full on-chip hardware support of semaphore signaling between ports
  • Fully asynchronous operation from either port
  • Separate byte controls for multiplexed bus and bus matching compatibility
  • Sleep Mode Inputs on both ports
  • Single 2.5V (±100mV) power supply for core
  • LVTTL-compatible, selectable 3.3V (±150mV)/2.5V (±100mV) power supply for I/Os and control signals on each port
  • Includes JTAG functionality
  • Available in a 256-ball BGA
  • Industrial temperature range (–40C to +85C) is available
