SC16C2550B

5 V, 3.3 V and 2.5 V dual UART, 5 Mbit/s (max.), with 16-byte

FIFOs

Rev. 05 — 12 January 2009

Product data sheet

1. General description

The SC16C2550B is a two channel 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 5 Mbit/s.

The SC16C2550B is pin compatible with the ST16C2550. It will power-up to be

functionally equivalent to the 16C2450. The SC16C2550B provides enhanced UART

functions with 16-byte FIFOs, modem control interface, DMA mode data transfer. The

DMA mode data transfer is controlled by the FIFO trigger levels and the TXRDYn and

RXRDYn signals. On-board status registers provide the user with error indications and

operational status. System interrupts and modem control features may be tailored by

software to meet speciﬁc user requirements. An internal loopback capability allows

on-board diagnostics. Independent programmable baud rate generators are provided to

select transmit and receive baud rates.

The SC16C2550B operates at 5 V, 3.3 V and 2.5 V and the industrial temperature range,

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

2. Features

SC16C550

I Up to 5 Mbit/s data rate at 5 V and 3.3 V and 3 Mbit/s at 2.5 V

I 16-byte transmit FIFO to reduce the bandwidth requirement of the external CPU

I 16-byte receive FIFO with error ﬂags to reduce the bandwidth requirement of the

external CPU

I Independent transmit and receive UART control

I Four selectable Receive FIFO interrupt trigger levels

I Software selectable baud rate generator

I Standard asynchronous error and framing bits (Start, Stop and Parity Overrun Break)

I Transmit, Receive, Line Status and Data Set interrupts independently controlled
