XR20M1280

I2C/SPI UART WITH 128-BYTE FIFO AND INTEGRATED LEVEL SHIFTERS

MAY 2011

REV. 1.0.0

FEATURES

GENERAL DESCRIPTION

• Integrated Level Shifters on CPU interface, UART

The XR20M1280 (M1280) is a single-channel I C/

SPI Universal Asynchronous Receiver and

Transmitter (UART) with integrated level shifters and

128 bytes of transmit and receive FIFOs.

and GPIO signals

• Selectable I C/SPI bus interface

• 26MHz maximum SPI clock

For flexibility in a mixed voltage environment, the

M1280 has 4 VCC pins. There is a VCC pin for the

core, a VCC pin for the UART signals, a VCC pin for

the CPU interface signals and a VCC pin for the

GPIO signals. The VCC pins for the UART, GPIO

• 24Mbps maximum UART data rate

• Up to 16 GPIOs

• 128-Bytes TX and RX FIFOs

• Programmable TX/RX trigger levels

• TX/RX FIFO Level Counters

and I C/SPI interface signals allow for the M1280 to

interface with devices operating at different voltage

levels eliminating the need for external voltage level

shifters. The VCC pin for the core voltage helps

lower the overall power consumption of applications

that use slower data rates.

• Independent TX/RX Baud Rate Generator

• Fractional Baud Rate Generator

• Auto RTS/CTS Hardware Flow Control

• Auto XON/XOFF Software Flow Control

• Auto RS-485 Half-Duplex Direction Control

• Multidrop mode w/ Auto Address Detect (RX)

• Multidrop mode w/ Address Byte Control (TX)

• Sleep Mode with Automatic Wake-up

• Infrared (IrDA 1.0 and 1.1) mode

• 1.62V to 3.63V supply operation

• 5V tolerant inputs

The Auto RS-485 Half-Duplex Direction control

feature simplifies both the hardware and software for

half-duplex RS-485 applications. In addition, the

Multidrop mode with Auto Address detection and

Address Byte Control features increase the

performance by simplifying the software routines.

The Independent TX/RX Baud Rate Generator

feature allows the transmitter and receiver to operate

at different baud rates. In addition, the Fractional

Baud Rate Generator feature provides flexibility for

crystal/clock frequencies for generating standard and

non-standard baud rates.

• Crystal oscillator or external clock input

APPLICATIONS

The M1280 has programmable transmit and receive

FIFO trigger levels, automatic hardware and software

flow control, and data rates of up to 24 Mbps. Power

consumption of the M1280 can be minimized by

enabling the sleep mode.

• Personal Digital Assistants (PDA)

• Cellular Phones/Data Devices

• Battery-Operated Devices

The M1280 has a 16550 compatible register set that

provide users with operating status and control,

receiver error indications, and modem serial interface

controls. An internal loopback capability allows

onboard diagnostics. The M1280 has a selectable

• Global Positioning System (GPS)

• Bluetooth

I C/SPI bus interface.

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