Product data sheet

1. General description

The SC16C852V is a 1.8 V, low power dual 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. SC16C852V can be programmed to operate in extended mode where

additional advanced UART features are available (see Section 6.2). The SC16C852V

family UART provides enhanced UART functions with 128-byte FIFOs, modem control

interface, DMA mode data transfer, and IrDA encoder/decoder. 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 speciï¬c 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 SC16C852V with Intel XScale processor VLIO interface operates at 1.8 V and is

available in HVQFN48 and TFBGA36 packages.
