1. General description
The SC16C850V is a 1.8 V, low power single 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. SC16C850V can be programmed to operate in extended mode where
additional advanced UART features are available (see Section 6.2
).The SC16C850V
family UART provides enhanced UART functions with 128-byte FIFOs, modem control
interface 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 SC16C850V with Intel XScale processor VLIO interface operates at 1.8 V and is
available in the HVQFN32 package.
