The 70V658 is a high-speed 64K x 36 Asynchronous Dual-Port Static RAM designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/ SLAVE Dual-Port RAM for 72-bit-or-more word system. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 72-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 enables (either CE0 or CE1) permit 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 72 bits or more using the Master/Slave select when cascading more than one device
  • 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 byte controls for multiplexed bus and bus matching compatibility
  • Includes JTAG functionality on BGA package versions only
  • LVTTL-compatible, single 3.3V (±150mV) power supply for core
  • LVTTL-compatible, selectable 3.3V (±150mV)/2.5V (±100mV) power supply for I/Os and control signals on each port
  • Available in a 208-pin PQFP, 208-ball fpBGA and 256-ball BGA
  • Industrial temperature range (–40C to +85C) is available
