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 specic 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.
