Features and Applications

The CY7C109D-10VXI is a high-performance CMOS static RAM organized as 131,072 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 tri-state drivers.The eight input and output pins (I/O0 through I/O7) are placed in a high-impedance state when:

  • Deselected (CE1 HIGH or CE2 LOW),
  • Outputs are disabled (OE HIGH),
  • When the write operation is active (CE1 LOW, CE2 HIGH, and WE LOW)


  • Pin- and function-compatible with CY7C109B/CY7C1009B
  • High speed
    • tAA = 10 ns
  • Low active power
    • ICC = 80 mA at 10 ns
  • Low CMOS standby power
    • ISB2 = 3 mA
  • 2.0 V Data Retention
  • Automatic power-down when deselected
  • TTL-compatible inputs and outputs
  • Easy memory expansion with CE1, CE2 and OE options
  • CY7C109D available in Pb-free 32-pin 400-Mil wide Molded SOJ and 32-pin TSOP I packages. CY7C1009D available in Pb-free 32-pin 300-Mil wide Molded SOJ package
