GENERAL DESCRIPTION

The XR20M1170

universal asynchronous receiver and transmitter

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

selectable I

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.
