Dual-Port Static RAM

Features

• True dual-ported memory cells which allow

• Automatic power-down

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

Master/Slave chip select when using more than one

device

simultaneous access of the same memory location

• 16K x 8 organization (CY7C006A)

• 32K x 8 organization (CY7C007A)

• 16K x 9 organization (CY7C016A)

• 32K x 9 organization (CY7C017A)

• 0.35-micron CMOS for optimum speed/power

• High-speed access: 12^[1]/15/20 ns

• Low operating power

— Active: I_CC= 180 mA (typical)

— Standby: I_SB3= 0.05 mA (typical)

• Fully asynchronous operation

• On-chip arbitration logic

• Semaphores included to permit software handshaking

between ports

• INT flags for port-to-port communication

• Pin select for Master or Slave

• Commercial temperature range

• Available in 68-pin PLCC (CY7C006A, CY7C007A and

CY7C017A), 64-pin TQFP (CY7C006A), and in 80-pin

TQFP (CY7C007A and CY7C016A)

Notes:

1. See page 7 for Load Conditions.

2. I/O –I/O for x8 devices; I/O –I/O for x9 devices.

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

4. A –A for 16K; A –A for 32K devices.
