Description

The SC16C752B is a dual universal asynchronous receiver/transmitter (UART) with

64-byte FIFOs, automatic hardware/software ﬂow control, and data rates up to

5 Mbit/s (3.3 V and 5 V). The SC16C752B offers enhanced features. It has a

transmission control register (TCR) that stores receiver FIFO threshold levels to

start/stop transmission during hardware and software ﬂow control. With the FIFO

RDY register, the software gets the status of TXRDY/RXRDY for all four 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 on-board diagnostics.

The UART transmits data, sent to it over the peripheral 8-bit bus, on the TX signal and

receives characters on the RX signal. Characters can be programmed to be 5, 6, 7, or

8 bits. The UART has a 64-byte receive FIFO and transmit FIFO and can be

programmed to interrupt at different trigger levels. The UART generates its own

desired baud rate based upon a programmable divisor and its input clock. It can

transmit even, odd, or no parity and 1, 1.5, or 2 stop bits. The receiver can detect

break, idle, or framing errors, FIFO overﬂow, and parity errors. The transmitter can

detect FIFO underﬂow. The UART also contains a software interface for modem

control operations, and has software ﬂow control and hardware ﬂow control

capabilities.

The SC16C752B is available in plastic LQFP48 and HVQFN32 packages.
