WCMA1008U1X - 128K x 8 Static RAM

Description

The WCMA1008U1X is a high-performance CMOS static RAM organized as 128K words by 8 bits.

Easy memory expansion is provided by an active LOW Chip Enable (CE1), an active HIGH Chip Enable (CE2), an active LOW Output Enable (OE) and three-state drivers.

Features

  • High Speed.
  • 55ns and 70ns availability.
  • Voltage range.
  • 2.7V.
  • 3.6V.
  • Ultra low active power.
  • Typical active current: 20 mA @ f = fmax (70ns speed).
  • Low standby power.
  • Easy memory expansion with CE and OE features.
  • Automatic power-down when deselected.
  • CMOS for optimum speed/power ic power-down feature, reducing the power consumption by over 99% when deselected. Writing to the device is accomplished by.

A1008U1X WCMA1008U1X 128K x 8 Static RAM Features • High Speed — 55ns and 70ns availability • Voltage range — 2.7V–3.6V • Ultra low active power — Typical active current: 20 mA @ f = fmax (70ns speed) • Low standby power • Easy memory expansion with CE and OE features • Automatic power-down when deselected • CMOS for optimum speed/power ic power-down feature, reducing the power consumption by over 99% when deselected. Writing to the device is accomplished by taking Chip Enable one (CE1) and Write Enable (WE) inputs LOW and the Chip Enable two (CE2) input HIGH. Data on the eight I/O pins (I/O0 through I/O7) is then written into the location specified on the address pins (A0 through A16).
