XR16M581
1.62V TO 3.63V UART WITH 16-BYTE FIFO AND VLIO INTERFACE
AUGUST 2009
REV. 1.0.1
GENERAL DESCRIPTION
The XR16M5811 (M581) is an enhanced Universal
Asynchronous Receiver and Transmitter (UART) with
a VLIO bus interface and has 16 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.
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
M581 can be minmized by enabling the sleep mode
and PowerSave mode.
The M581 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 M581 is available in 24-pin
QFN, 32-pin QFN and 25-pin BGA packages.
NOTE: 1 Covered by U.S. Patent #5,649,122.
