CY7C008/009

CY7C018/019

64K/128K x 8/9 Dual-Port Static RAM

Features

• True Dual-Ported memory cells which allow simulta-

neous access of the same memory location

• Fully asynchronous operation

• Automatic power-down

• 64K x 8 organization (CY7C008)

• 128K x 8 organization (CY7C009)

• 64K x 9 organization (CY7C018)

• 128K x 9 organization (CY7C019)

• 0.35-micron CMOS for optimum speed/power

• High-speed access: 12^[1]/15/20 ns

• Low operating power

• Expandable data bus to 16/18 bits or more using Mas-

ter/Slave chip select when using more than one device

• On-chip arbitration logic

• Semaphores included to permit software handshaking

between ports

• INT flags for port-to-port communication

• Dual Chip Enables

• Pin select for Master or Slave

• Commercial and Industrial temperature ranges

• Available in 100-pin TQFP

— Active: I_CC= 180 mA (typical)

—Standby: I_SB3= 0.05 mA (typical)
