8-bit (Intel/Motorola/VLIO) UART with 128-Byte FIFO and Integrated Level Shifters

XR16M890

Single-Channel UARTs with Selectable Bus Interfaces

Simplify Mixed Voltage Designs for Next Generation Systems

The XR16M890¹(M890) is a single-channel Universal Asynchronous Receiver

and Transmitter (UART) with integrated level shifters and 128 bytes of transmit

FEATURES

• Integrated Level Shifters on

CPU interface, UART and

GPIO signals

and receive FIFOs.

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. The VCC core voltage helps to lower the overall power

consumption for applications that use slower data rates.

• Intel/Motorola/VLIO Bus

Interface select

• 24 Mbps maximum UART data

rate

• Up to 16 GPIOs

• 128-Bytes TX and RX FIFOs

• Programmable TX/RX trigger

levels

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.

• TX/RX FIFO Level Counters

• Independent TX/RX Baud Rate

Generator

• Fractional Baud Rate Generator

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.

• Auto RTS/CTS Hardware Flow

Control

• Auto XON/XOFF Software Flow

Control

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.

• Auto RS-485 Half-Duplex

Direction Control

• Multidrop mode w/ Auto

Address Detect (RX)

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.

• Multidrop mode w/ Address

Byte Control (TX)

• Sleep Mode with Automatic

Wake-up

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

• Infrared (IrDA 1.0 and 1.1)

mode

• 1.62V to 3.63V supply operation

• Crystal oscillator or external

clock input

• 5V tolerant inputs
