SC16C2552

Dual UART with 16-byte transmit and receive FIFOs

Rev. 03 — 20 June 2003

Product data

1. Description

The SC16C2552 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 Mbits/s.

The SC16C2552 is pin compatible with the PC16C552 and ST16C2552. It will

power-up to be functionally equivalent to the 16C2450. The SC16C2552 provides

enhanced UART functions with 16 byte FIFOs, modem control interface, DMA mode

data transfer and concurrent writes to control registers of both channels. The DMA

mode data transfer is controlled by the FIFO trigger levels and the RXRDY and

TXRDY 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 loop-back capability allows

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

to select transmit and receive baud rates.

The SC16C2552 operates at 5 V, 3.3 V and 2.5 V, and the Industrial temperature

range, and is available in a plastic PLCC44 package.

2. Features

■ Industrial temperature range (−40 °C to +85 °C)

■ 5 V, 3.3 V and 2.5 V operation

■ Pin-to-pin and functionally compatible to PC16C552, ST16C2552

■ Software compatible with INS8250, NS16C550

■ Up to 5 Mbits/s data rate at 5 V and 3 V, and 3 Mbits/s at 2.5 V

■ 16-byte transmit FIFO

■ 16-byte receive FIFO with error ﬂags

■ Independent transmit and receive UART control

■ Four selectable Receive FIFO interrupt trigger levels; ﬁxed XMIT FIFO interrupt

trigger level

■ Modem control signals (CTS, RTS, DSR, DTR, RI, CD)

■ DMA operation and DMA monitoring via package I/O pins, TXRDY/RXRDY

■ UART internal register sections A and B may be written to concurrently

■ Multi-function output allows more package functions with fewer I/O pins

■ Programmable character lengths (5, 6, 7, 8), with even, odd, or no parity
