SC16C750

Universal Asynchronous Receiver/Transmitter (UART)

with 64-byte FIFO

Rev. 04 — 20 June 2003

Product data

1. General description

The SC16C750 is a Universal Asynchronous Receiver and Transmitter (UART) used

for serial data communications. Its principal function is to convert parallel data into

serial data, and vice versa. The UART can handle serial data rates up to 3 Mbits/s.

The SC16C750 is pin compatible with the TL16C750 and it will power-up to be

functionally equivalent to the 16C450. Programming of control registers enables the

added features of the SC16C750. Some of these added features are the 64-byte

receive and transmit FIFOs, automatic hardware ﬂow control. The selectable

auto-ﬂow control feature signiﬁcantly reduces software overload and increases

system efﬁciency while in FIFO mode by automatically controlling serial data ﬂow

using RTS output and CTS input signals. The SC16C750 also provides DMA mode

data transfers through FIFO trigger levels and the TXRDY and RXRDY signals.

On-board 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 SC16C750 operates at 5 V, 3.3 V and 2.5 V, the industrial temperature range and

is available in plastic PLCC44 and LQFP64 packages.

2. Features

■ 5 V, 3.3 V and 2.5 V operation

■ Industrial temperature range

■ After reset, all registers are identical to the typical 16C450 register set

■ Capable of running with all existing generic 16C450 software

■ Pin compatibility with the industry-standard ST16C450/550, TL16C450/550,

PC16C450/550

■ Up to 3 Mbits/s transmit/receive operation at 5 V, 2 Mbits/s at 3.3 V, and

1 Mbit/s at 2.5 V

■ 64 byte transmit FIFO

■ 64 byte receive FIFO with error ﬂags

■ Programmable auto-RTS and auto-CTS

◆ In auto-CTS mode, CTS controls transmitter

◆ In auto-RTS mode, RxFIFO contents and threshold control RTS

■ Automatic hardware ﬂow control

■ Software selectable Baud Rate Generator

■ Four selectable Receive interrupt trigger levels

■ Standard modem interface

■ Sleep mode
