XR16M890

UART WITH 128-BYTE FIFO AND INTEGRATED LEVEL SHIFTERS

APRIL 2011

REV. 1.0.0

FEATURES

GENERAL DESCRIPTION

• Integrated Level Shifters on CPU interface, UART

The XR16M890

(M890) is

single-channel

and GPIO signals

Universal Asynchronous Receiver and Transmitter

(UART) with integrated level shifters and 128 bytes of

transmit and receive FIFOs.

• Intel/Motorola/VLIO Bus Interface select

■ ’0’ ns address setup/hold times

• 24 Mbps maximum UART data rate

• Up to 16 GPIOs

For flexibility in a mixed voltage environment, the

M890 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

and CPU interface signals allow for the M890 to

interface with devices operating at different voltage

levels eliminating the need for external voltage level

shifters.

• 128-Bytes TX and RX FIFOs

• Programmable TX/RX trigger levels

• TX/RX FIFO Level Counters

• 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.

The M890 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 M890 can be minimized by

enabling the sleep mode.

• Crystal oscillator or external clock input

APPLICATIONS

• Personal Digital Assistants (PDA)

• Cellular Phones/Data Devices

• Battery-Operated Devices

• Global Positioning System (GPS)

• Bluetooth

The M890 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 M890 has a selectable

Intel/Motorola/VLIO bus interface.

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