XR16M670
1.62V TO 3.63V HIGH PERFORMANCE UART WITH 32-BYTE FIFO
DECEMBER 2009
REV. 1.0.1
GENERAL DESCRIPTION
The XR16M6701 (M670) is an enhanced Universal
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.
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
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.
NOTE: 1 Covered by U.S. Patent #5,649,122.
