Description

The CY7C0852V-150BBC is a Low-Power CMOS dual-port static RAM available in 64K x 8/ 128K x 8/ 64K x 9/ 128K x 9 organizations. It is used as 8/9-bit dual-port static RAM, and multiple devices can be combined to create a 16/18-bit or wider master/slave dual-port static RAM. It has various arbitration schemes to handle and resolve conflicts when multiple processors access the same data.

• High-speed access: 12[1]/15/20 ns.

• 0.35-micron CMOS for optimum speed/power.

• Fully asynchronous operation.

• Automatic power-down.

• On-chip arbitration logic.

• Semaphores included to permit software handshaking between ports.

• Dual Chip Enables.

• Commercial and Industrial temperature ranges.

Application Scenarios

The CY7C0852V-150BBC is widely used in various applications such as network routers, switches, storage systems, and telecommunications devices.

Comparison
