3 Description
The TL16C752CI-Q1 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.
