The CY7C006A-20AXI 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.
Feature

• 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
