3 Description

The TL16C752D 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.

With the FIFO RDY register, the software gets the

status of TXRDY or RXRDY for all two ports in one

access. On-chip status registers provide the user with

error indications, operational status, and modem

interface control. System interrupts may be tailored to

meet user requirements. An internal loop-back

capability allows onboard diagnostics. The

TL16C752D incorporates the functionality of two

UARTs, each UART having its own register set and

FIFOs.
