SC16C2550
Dual UART with 16 bytes of transmit and receive FIFOs
and infrared (IrDA) encoder/decoder
Rev. 03 — 19 June 2003
Product data
1. Description
The SC16C2550 is a 2 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 SC16C2550 is pin compatible with the ST16C2550. It will power-up to be
functionally equivalent to the 16C2450. The SC16C2550 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 TXRDY and
RXRDY 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 SC16C2550 operates at 5 V, 3.3 V and 2.5 V and the Industrial temperature
range, and is available in plastic PLCC44, LQFP48 and DIP40 packages.
