XR16M770

1.62V TO 3.63V HIGH PERFORMANCE UART WITH 64-BYTE FIFO

FEBRUARY 2009

REV. 1.0.0

FEATURES

GENERAL DESCRIPTION

• Pin-to-pin compatible with XR16L570 in 24-QFN

The XR16M770 (M770) is an enhanced Universal

and 32-QFN packages

Asynchronous Receiver and Transmitter (UART) with

64 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 16 Mbps at 3.3V, 12.5 Mbps at

2.5V and 7.5 Mbps at 1.8V with 4X data sampling

rate.

• Intel data bus Interface

• 16 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 in 24-pin QFN package

• Infrared (IrDA 1.0 and 1.1) mode

• 1.62V to 3.63V supply operation

• Crystal oscillator or external clock input

APPLICATIONS

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

M770 can be minimized by enabling the sleep mode

and PowerSave mode.

The M770 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 M770 is available in 24-pin

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

three packages offer the 16 mode (Intel bus) interface

only.

• 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
