General description

The SC16C2552B 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 SC16C2552B is pin compatible with the PC16552 and ST16C2552. The

SC16C2552B 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 loopback capability

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

provided to select transmit and receive baud rates.

The SC16C2552B operates at 5 V, 3.3 V and 2.5 V and the industrial temperature range,

and is available in a plastic PLCC44 package.
