XR16M681

1.62V TO 3.63V UART WITH 32-BYTE FIFO AND VLIO INTERFACE

AUGUST 2009

REV. 1.0.1

FEATURES

GENERAL DESCRIPTION

• VLIO bus interface

The XR16M681 (M681) is an enhanced Universal

Asynchronous Receiver and Transmitter (UART) with

a VLIO bus interface and has 32 bytes of transmit

and receive FIFOs, programmable transmit and

receive FIFO trigger levels, automatic hardware and

software flow control, and data rates of up to 20 Mbps

at 3.3V, 16 Mbps at 2.5V and 10 Mbps at 1.8V with

4X data sampling rate.

• Pin-to-pin compatible with SC16C850V and

SC16C850SV in 32-QFN package

• 20 Mbps maximum data rate

• Programmable TX/RX FIFO 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

• Sleep Mode with Automatic Wake-up

• PowerSave mode

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

increases 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. Power consumption of the

M681 can be minmized by enabling the sleep mode

and PowerSave mode.

• Infrared (IrDA 1.0 and 1.1) mode

• 1.62V to 3.63V supply operation

• Crystal oscillator or external clock input

APPLICATIONS

The M681 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 M681 is available in 24-pin

QFN, 32-pin QFN and 25-pin BGA packages.

• Personal Digital Assistants (PDA)

• Cellular Phones/Data Devices

• Battery-Operated Devices

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

• Global Positioning System (GPS)

• Bluetooth
