The Renesas Electronics FIFO memory that loads and empties data on a first-in/first-out basis. The device uses Full and Empty flags to prevent data overflow and underflow. It has a retransmit capability that allows for reset of the read pointer to its initial position when RT is pulsed LOW. It is designed for those applications requiring asynchronous and simultaneous read/writes in multiprocessing and rate buffer applications.

Pin and functionally compatible with 720X family
Low power consumption
Ultra high speed 12ns access time
Asynchronous and simultaneous read and write
Fully expandable by both word depth and/or bit width
Auto-retransmit capability
