WCMA1008C1X - 128K x 8 Static RAM

Description

The WCMA1008C1X is a high-performance CMOS static RAM organized as 128K words by 8 bits.

Features

  • Voltage Range.
  • 4.5V.
  • 5.5V.
  • Low active power.
  • Typical active current: 6 mA @ f = fmax (70 ns speed).
  • Low standby current.
  • Automatic power-down when deselected.
  • TTL-compatible inputs and outputs.
  • Easy memory expansion with CE1, CE2, and OE features.
  • CMOS for optimum speed/power (OE), and three-state drivers. This device has an automatic power-down feature that reduces power consumption by more than 75% when de.

WCMA1008C1X 128K x 8 Static RAM Features • Voltage Range — 4.5V–5.5V • Low active power — Typical active current: 6 mA @ f = fmax (70 ns speed) • Low standby current • Automatic power-down when deselected • TTL-compatible inputs and outputs • Easy memory expansion with CE1, CE2, and OE features • CMOS for optimum speed/power (OE), and three-state drivers. This device has an automatic power-down feature that reduces power consumption by more than 75% when deselected. Writing to the device is accomplished by taking Chip Enable 1 (CE1) and Write Enable (WE) inputs LOW and Chip Enable 2 (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).
