XR16V2550
HIGH PERFORMANCE DUART WITH 16-BYTE FIFO
JULY 2012
REV. 1.0.3
GENERAL DESCRIPTION
The XR16V25501 (V2550) is a high performance dual
universal asynchronous receiver and transmitter
(UART) with 16 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 and XR16C2550. The V2550 register set
is compatible to the ST16C2550 and the XR16L2550.
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 V2550
is available in 48-pin TQFP and 32-pin QFN
packages.
