XR16M670  
1.62V TO 3.63V HIGH PERFORMANCE UART WITH 32-BYTE FIFO  
DECEMBER 2009  
REV. 1.0.1  
FEATURES  
GENERAL DESCRIPTION  
• Pin-to-pin compatible with XR16L570 in 24-QFN  
1
The XR16M670 (M670) is an enhanced Universal  
and 32-QFN packages  
Asynchronous Receiver and Transmitter (UART) with  
32 bytes of transmit and receive FIFOs, selectable  
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  
• Selectable TX/RX FIFO Trigger Levels  
• TX/RX FIFO Level Counters  
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.  
• 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 Independent TX/RX Baud Rate Generator  
feature allows the transmitter and receiver to operate  
at different baud rates. Power consumption of the  
M670 can be minimized by enabling the sleep mode  
and PowerSave mode.  
The M670 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 M670 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
