XR16M2550
HIGH PERFORMANCE LOW VOLTAGE DUART WITH 16-BYTE FIFO
MAY 2007
REV. 1.0.2
GENERAL DESCRIPTION
The XR16M25501 (M2550) is a high performance
dual universal asynchronous receiver and transmitter
(UART) with 16 bytes TX and RX FIFOs. The device
operates from 1.62 to 3.63 volts and is pin-to-pin and
software compatible to the ST16C2550, XR16L2550,
and XR16V2550. It supports Exar’s enhanced
features of selectable FIFO trigger level, automatic
hardware (RTS/CTS) and software flow control, and a
complete modem interface. Onboard registers
provide the user with operational status and data
error flags. An internal loopback capability allows
system diagnostics. Independent programmable
baud rate generators are provided in each channel to
select data rates up to 16 Mbps at 3.3 Volt with 4X
sampling clock. The M2550 is available in 48-pin
TQFP and 32-pin QFN packages.
