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.
