1. General description

2. Features

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.
