3 Description

The TL16C752C is a dual universal asynchronous

receiver transmitter (UART) with 64-byte FIFOs,

automatic hardware and software flow control, and

data rates up to 3 Mbps. The device offers enhanced

features. It has a transmission Character control

register (TCR) that stores received FIFO threshold

level to start or stop transmission during hardware

and software flow control.
