XR20M1170

I2C/SPI UART WITH 64-BYTE FIFO

REV. 1.0.0

MAY 2007

FEATURES

GENERAL DESCRIPTION

• 1.62 to 3.6 Volt Operation

• Selectable I²C/SPI Interface

• Full-featured UART

The XR20M1170 (M1170) is a high performance

universal asynchronous receiver and transmitter

(UART) with 64 byte TX and RX FIFOs and a

selectable I²C/SPI slave interface. The M1170

operates from 1.62 to 3.63 volts. The enhanced

features in the M1170 include a programmable

fractional baud rate generator, an 8X and 4X

sampling rate that allows for a maximum baud rate of

16 Mbps at 3.3V. The standard features include 16

selectable TX and RX FIFO trigger levels, automatic

hardware (RTS/CTS) and software (Xon/Xoff) flow

control, and a complete modem interface. Onboard

registers provide the user with operational status and

data error flags. An internal loopback capability

allows system diagnostics. The M1170 is available in

the 28-pin QFN, 24-pin QFN, 16-pin QFN, 24-pin

TSSOP and 16-pin TSSOP packages. The 28-pin

QFN package has the EN485# and ENIR# pins to

allow the UART to power-up in the Auto RS485 mode

or the Infrared mode.

■ Data rate of up to 16 Mbps at 3.3 V

■ Data rate of up to 12.5 Mbps at 2.5 V

■ Data rate of up to 8 Mbps at 1.8 V

■ Fractional Baud Rate Generator

■ Transmit and Receive FIFOs of 64 bytes

■ 16 Selectable TX and RX FIFO Trigger Levels

■ Automatic Hardware (RTS/CTS) Flow Control

Control Output via RTS#

■ Wireless Infrared (IrDA 1.0 and 1.1) Encoder/

Decoder

■ Automatic sleep mode (< 15 uA at 3.3V)

■ General Purpose I/Os

NOTE: 1 Covered by U.S. Patent #5,649,122
