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 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 SC16C852V with Intel XScale processor VLIO interface operates at 1.8 V and is
available in HVQFN48 and TFBGA36 packages.
