2.5 V to 3.3 V UART, 5 Mbit/s (max.) with 128-byte FIFOs, infrared (Ir DA), and 16 mode or 68 mode parallel bus interface Rev. 01 - 10 January 2008 Product data sheet 1. General description 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 munications. 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) patible with the SC16C650B. SC16C850 can be programmed to operate in extended mode (see Section 6.2) where additional advanced UART Features are available. The SC16C850 UART provides enhanced UART functions with 128-byte FIFOs, modem control interface, and Ir DA 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. 2.
