描述
The 7202 is a 1K x 9 dual-port 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 (RT) 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.
