1. General description
2. Features
The SC16C850 is a 2.5 V to 3.3 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. The SC16C850 is functionally (software) compatible with
the SC16C650B. SC16C850 can be programmed to operate in extended mode (see
Section
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.
The SC16C850IBS with Intel (16 mode) or Motorola (68 mode) bus host interface
operates at 2.5 V to 3.3 V and is available in a very small (Micro-UART) HVQFN32
package.
The SC16C850IET with Intel (16 mode) bus host interface operates at 2.5 V to 3.3 V and
is available in a very small TFBGA36 package.
