72V70190PFG

Overview

The 72V70190PFG is a high-speed 32K x 18 synchronous dual-port RAM manufactured by Renesas Electronics Corporation. It features full synchronous operation on both ports, allowing simultaneous access to the same memory location without additional logic. The device supports selectable pipelined or flow-through output modes and includes counter enable and repeat features for flexible data handling. Designed for burst-oriented unidirectional or bidirectional data flow, it incorporates an automatic power-down feature controlled by chip enables to minimize standby power consumption.

Feature Summary

• Dual-port architecture enabling simultaneous read/write access to shared memory locations
• Full synchronous operation with selectable pipelined or flow-through output modes
• Integrated hardware support for depth expansion via dual chip enables
• Automatic low-power standby mode controlled by chip enable signals

Applications

• High-speed data buffering in industrial network systems
• Bidirectional data flow management in burst-mode applications
• Master/Slave dual-port RAM configurations for expanded word systems
