WCMA4016U1X - 256K x 16 Static RAM

Description

of read and write modes.

The WCMA4016U1X is a high-performance CMOS static RAM organized as 262,144 words by 16 bits.

Features

  • Low voltage range: 2.7V.
  • 3.6V.
  • Ultra-low active, standby power.
  • Easy memory expansion with CE1 and CE2 and OE features.
  • TTL-compatible inputs and outputs.
  • Automatic power-down when deselected.
  • CMOS for optimum speed/power both BHE and BLE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE1HIGH or CE2 LOW), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low En.

Y62147BV L™ WCMA4016U1X 256K x 16 Static RAM Features • Low voltage range: 2.7V–3.6V • Ultra-low active, standby power • Easy memory expansion with CE1 and CE2 and OE features • TTL-compatible inputs and outputs • Automatic power-down when deselected • CMOS for optimum speed/power both BHE and BLE are HIGH). The input/output pins (I/O0 through I/O15) are placed in a high-impedance state when: deselected (CE1HIGH or CE2 LOW), outputs are disabled (OE HIGH), both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH), or during a write operation (CE1 LOW, CE2 HIGH and WE LOW). Writing to the device is accomplished by taking Chip Enables (CE1 LOW and CE2 HIGH) and Write Enable (WE) input LOW.
