SC16C750B

5 V, 3.3 V and 2.5 V UART with 64-byte FIFOs

Rev. 05 — 17 October 2008

Product data sheet

1. General description

The SC16C750B 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 Mbit/s.

The SC16C750B 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 SC16C750B. 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 SC16C750B 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 loopback capability allows

on-board diagnostics.

The SC16C750B operates at 5 V, 3.3 V and 2.5 V, the industrial temperature range and is

available in plastic PLCC44, LQFP64, and HVQFN32 packages.

PC16C450/550. Software compatible with SC16C750 and TL16C750

I Up to 3 Mbit/s transmit/receive operation at 5 V, 2 Mbit/s at 3.3 V, and 1 Mbit/s at 2.5 V

I 64-byte transmit FIFO

I 64-byte receive FIFO with error ﬂags

I Programmable auto-RTS and auto-CTS

N In auto-CTS mode, CTS controls transmitter

N In auto-RTS mode, receive FIFO contents and threshold control RTS
