IDT70V631S - HIGH-SPEED 3.3V 256K x 18 ASYNCHRONOUS DUAL-PORT STATIC RAM

Description

address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory.

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

  • Fully asynchronous operation from either port Separate byte controls for multiplexed bus and bus matching compatibility Supports JTAG features compliant to IEEE 1149.1.
  • Due to limited pin count, JTAG is not supported on the 128-pin TQFP package. 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 128-pin.
