Cypress CY7C1353B-66AC

256K x 187 ns0°C ~ 70°C（TA）

Overview

The CY7C1353B-66AC and CY7C1342 are high-speed CMOS 4K x 8 dual-port static RAMs. The CY7C1342 includes semaphores that provide a means to allocate portions of the dual-port RAM or any shared resource. Two ports are provided permitting independent, asynchronous access for reads and writes to any location in memory. Application areas include interprocessor/multiprocessor designs, communications status buffering, and dual-port video/graphics memory.

• True Dual-Ported memory cells which allow simultaneous reads of the same memory location• 4K x 8 organization• 0.65-micron CMOS for optimum speed/power• High-speed access: 15 ns• Low operating power: ICC = 160 mA (max.)• Fully asynchronous operation• Automatic power-down• Semaphores included on the 7C1342 to permit software handshaking between ports• Available in 52-pin PLCC• Pb-Free packages available
