SC16C650B

5 V, 3.3 V and 2.5 V UART with 32-byte FIFOs

and infrared (IrDA) encoder/decoder

Rev. 03 — 10 December 2004

Product data

1. General description

The SC16C650B 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 SC16C650B is pin compatible with the ST16C650A and it will power-up to be

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

added features of the SC16C650B. Some of these added features are the 32-byte

receive and transmit FIFOs, automatic hardware or software ﬂow control and infrared

encoding/decoding. 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 SC16C650B also provides DMA mode data transfers through FIFO trigger levels

and the RXRDY and TXRDY 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 SC16C650B operates at 5 V, 3.3 V and 2.5 V, and the industrial temperature

range, and is available in plastic DIP40, PLCC44, LQFP48, and HVQFN32 packages.

2. Features

PC16C450/550. Software compatible with ST16C650.

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

32 byte transmit FIFO

32 byte receive FIFO with error ﬂags

Programmable auto-RTS and auto-CTS

In auto-CTS mode, CTS controls transmitter
