CY7C006-55AC

16K X 8/9双口静态RAM与扫描电镜，诠释，忙 16K x 8/9 Dual-Port Static RAM with Sem, Int, Busy

Functional Description

The CY7C006 and CY7C016 are high-speed CMOS 16K x 8 and 16K x 9 dual-port static RAMs. Various arbitration schemes are included on the CY7C006/016 to handle situations when multiple processors access the same piece of data. Two ports are provided, permitting independent, asynchro nous access for reads and writes to any location in memory.

Features

• True dual-ported memory cells which allow simultaneous reads of the same memory location

• 16K x 8 organization CY7C006

• 16K x 9 organization CY7C016

• 0.65-micron CMOS for optimum speed/power

• High-speed access: 15 ns

• Low operating power: ICC= 140 mA typ.

• Fully asynchronous operation

• Automatic power-down

• TTL compatible

• Expandable data bus to 16/18 bits or more using Master/Slave chip select when using more than one device

• Busy arbitration scheme provided

• Semaphores included to permit software handshaking between ports

•INTflag for port-to-port communication

• Available in 68-pin PLCC 7C006, 64-pin 7C006 and 80-pin 7C016 TQFP

• Pin compatible and functional equivalent to IDT7006/IDT7016
