WCMA4016U4X - 256K x 16 Static RAM

Description

of read and write modes.

The WCMA4016U4X is available in a 48-ball FBGA package.

The WCMA4016U4X is a high-performance CMOS static RAMs organized as 256K words by 16 bits.

Features

  • Low Voltage range:.
  • 2.7V-3.3V.
  • Ultra-low active power.
  • Typical active current: 1.5 mA @ f = 1MHz.
  • Typical active current: 7 mA @ f = fmax Low standby power Easy memory expansion with CE and OE features Automatic power-down when deselected CMOS for optimum speed/power more than 99% when deselected (CE HIGH or both BLE and BHE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance st.

A4016U4X WCMA4016U4X 256K x 16 Static RAM Features • Low Voltage range: — 2.7V-3.3V • Ultra-low active power — Typical active current: 1.5 mA @ f = 1MHz • • • • — Typical active current: 7 mA @ f = fmax Low standby power Easy memory expansion with CE and OE features Automatic power-down when deselected CMOS for optimum speed/power more than 99% when deselected (CE HIGH or both BLE and BHE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE HIGH), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE LOW and WE LOW). Writing to the device is accomplished by taking Chip Enable (CE) and Write Enable (WE) inputs LOW.
