SC16C754

Quad UART with 64-byte FIFO

Rev. 04 — 19 June 2003

Product data

1. Description

The SC16C754 is a quad universal asynchronous receiver/transmitter (UART) with

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

5 Mbits/s (3.3 V and 5 V). The SC16C754 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 SC16C754 is available in plastic LQFP80 and PLCC68 packages.

2. Features

■ Pin compatible with SC16C654IA68 and SC16C554IA68 with additional

enhancements

■ Up to 5 Mbits/s baud rate (at 3.3 V and 5 V; at 2.5 V maximum baud rate is

3 Mbits/s)

■ 64-byte transmit FIFO

■ 64-byte receive FIFO with error ﬂags

■ Programmable and selectable transmit and receive FIFO trigger levels for DMA

and interrupt generation

■ Software/hardware ﬂow control

◆ Programmable Xon/Xoff characters

◆ Programmable auto-RTS and auto-CTS

■ Optional data ﬂow resume by Xon any character

■ DMA signalling capability for both received and transmitted data

■ Supports 5 V, 3.3 V and 2.5 V operation

■ Software selectable baud rate generator
