XR16V2552
HIGH PERFORMANCE DUART WITH 16-BYTE FIFO
MARCH 2010
REV. 1.0.3
GENERAL DESCRIPTION
The XR16V2552
1
(V2552) is a high performance dual
universal asynchronous receiver and transmitter
(UART) with 16 byte 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
ST16C2552 and XR16L2552. The V2552 register set
is compatible to the ST16C2552 and the XR16L2552.
It supports the Exar’s enhanced features of
selectable FIFO trigger level, automatic hardware
(RTS/CTS) and software (Xon/Xoff) 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 V2552 is available in 44-pin
PLCC and 32-pin QFN packages.
