Description

The SC16C652B 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 Mbit/s. The SC16C652B is pin compatible with the SC16C2550. It will

power-up to be functionally equivalent to the 16C2450. The SC16C652B provides

enhanced UART functions with 32-byte FIFOs, modem control interface, DMA mode

data transfer, and IrDA encoder/decoder. 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 SC16C652B operates at 5 V, 3.3 V and 2.5 V and the Industrial temperature

range, and is available in plastic LQFP48 and very small (Micro-UART) HVQFN32

packages.
