70V5388 - Block Diagram


64K x 18 FourPort RAM

The 70V5388 is a high-speed 64Kx18 bit synchronous FourPort RAM that allows simultaneous access of any address from all four ports and is optimized for applications having unidirectional or bi-directional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode. It provides a wide range of functions specially designed to facilitate system operations.


  • True four-ported memory cells allow simultaneous access of the same memory location
  • Synchronous Pipelined device allows fast 200MHz operation
  • High Bandwidth up to 14 Gbps (200MHz x 18 bits wide x 4 ports)
  • LVTTL I/O interface
  • High-speed clock to data access 3.0ns (max.)
  • 3.3V Low operating power
  • Interrupt flags for message passing
  • Width and depth expansion capabilities
  • Counter readback on address lines Mask register readback on address lines
  • Global Master reset for all ports
  • Dual Chip Enables on all ports for easy depth expansion
  • Separate upper-word and lower-word controls on all ports
  • Available in 272-BGA and 256-BGA packages
  • JTAG boundary scan
  • MBIST (Memory Built-In Self Test) controller
  • Industrial temperature range (-40C to +85C) is available
