XR16L580
SMALLEST 2.25V TO 5.5V UART WITH 16-BYTE FIFO AND POWERSAVE
AUGUST 2011
REV. 1.4.2
GENERAL DESCRIPTION
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 very small 32-QFN and 24-QFN packages in industrial
temperature range.
