XR16V2650
HIGH PERFORMANCE DUART WITH 32-BYTE FIFO
MAY 2007
REV. 1.0.2
GENERAL DESCRIPTION
The XR16V26501 (V2650) is a high performance dual
universal asynchronous receiver and transmitter
(UART) with 32 bytes TX and RX FIFOs. The device
operates from 2.25 to 3.6 volts with 5 Volt tolerant
inputs and is pin-to-pin compatible to Exar’s
ST16C2550, XR16C2550 and XR16V2550. The
V2650 register set is compatible to the ST16C2550,
the XR16L2550 and the 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 V2650 is
available in 48-pin TQFP and 32-pin QFN packages.
