XR16L580
SMALLEST 2.25V TO 5.5V UART WITH 16-BYTE FIFO AND POWERSAVE
JANUARY 2004
GENERAL DESCRIPTION
REV. 1.2.0
The XR16L580 (L580) is a 2.25 to 5.5 volt Universal
Asynchronous Receiver and Transmitter (UART) with
5 volt tolerant inputs and a reduced pin count. It is
pin-to-pin and software compatible to industry
standard 16C450, 16C550, ST16C580, ST16C650A
and XR16C850 UARTs. It has 16 bytes of TX and RX
FIFOs and is capable of operating up to serial data
rate of 1 Mbps at 2.25 volt supply voltage. The
internal registers is compatible to the 16C550
register set plus enhanced registers for additional
features to support today’s high bandwidth data
communication needs. The enhanced features
include Intel or Motorola data bus interface to match
your CPU interface, automatic hardware and
software flow control to prevent data loss, selectable
RX and TX trigger levels for more efficient interrupt
service, wireless infrared (IrDA) encoder/decoder for
wireless applications and a unique Power-Save mode
to increase battery operating time. The device comes
in the 48-TQFP and a very small 32-QFN packages in
industrial temperature range.
