Overview

CY7C135, CY7C135A CY7C1342 4K x 8 Dual-Port Static RAM and 4K x 8 Dual-Port SRAM with Semaphores Features ■ 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 and 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 Logic Block Diagram R/WL CEL OEL Functional Description The CY7C135/135A[1] 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, communicatio...
