3.3V 64K/128K x 8/9

Dual-Port Static RAM

• Fully asynchronous operation

• Automatic power-down

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

ter/Slave chip select when using more than one device

Features

• True Dual-Ported memory cells which allow simulta-

neous access of the same memory location

• 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: 15/20/25 ns

• Low operating power

• On-chip arbitration logic

• Semaphores included to permit software handshaking

between ports

• INT flag 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= 115 mA (typical)

— Standby: I_SB3= 10 µA (typical)

Notes:

1. I/O₀–I/O₇for x8 devices; I/O₀–I/O₈for x9 devices.

2. A₀–A₁₅for 64K devices; A₀–A₁₆for 128K.

3. BUSY is an output in master mode and an input in slave mode.
