XR16L570
SMALLEST 1.62V TO 5.5V UART WITH 16-BYTE FIFO AND POWERSAVE
MAY 2007
REV. 1.0.1
GENERAL DESCRIPTION
The XR16L570 (L570) is a 1.62 to 5.5 volt Universal
Asynchronous Receiver and Transmitter (UART) with 5 volt
tolerant inputs and a reduced pin count. It is software
compatible
to
industry
standard
16C450,
16C550,
ST16C580,
ST16C650A,
XR16C850
and
XR16L580
UARTs. It has 16 bytes of TX and RX FIFOs and is capable
of operating with a serial data rate of up to 4 Mbps at 5V, 3
Mbps at 3.3V,1 Mbps at 2.5V and 750 Kbps at 1.8V. The
internal registers are 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
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 32-QFN and
24-QFN packages in industrial temperature range.
