PRELIMINARY

CY7C0241V/0251V/036V

3.3V 4K/8K/16K x 16/18 Dual-Port Static RAM

• Automatic power-down

Features

• Expandable data bus to 32/36 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 flag for port-to-port communication

• Separate upper-byte and lower-byte control

• Pin select for Master or Slave

• True dual-ported memory cells which allow simulta-

neous access of the same memory location

• 4/8/16K x 16 organization (CY7C024V/025V/026V)

• 4/8K x 18 organization (CY7C0241V/0251V)

• 16K x 18 organization (CY7C036V)

• 0.35-micron CMOS for optimum speed/power

[1]

• High-speed access: 15 /20/25 ns

• Low operating power

• Commercial and industrial temperature ranges

• Available in 100-pin TQFP

Active: I = 115 mA (typical)

—

• Pin-compatible and functionally equivalent to

IDT70V24, 70V25, and 7V0261.

— Standby: I

= 10 A (typical)

SB3

• Fully asynchronous operation
