XR16C854/XR16C854D
3.3V AND 5V QUAD UART WITH 128-BYTE FIFO
APRIL 2002
REV. 2.0
GENERAL DESCRIPTION
The XR16C854/854D
1
(854) is an enhanced quad
Universal Asynchronous Receiver and Transmitter
(UART) each with 128 bytes of transmit and receive
FIFOs, transmit and receive FIFO counters and trig-
ger levels, automatic hardware and software flow con-
trol, and data rates of up to 2 Mbps. Each UART has
a set of registers that provide the user with operating
status and control, receiver error indications, and mo-
dem serial interface controls. Selectable interrupt po-
larity provides flexibility to meet design require-
ments. An internal loopback capability allows on-
board diagnostics. The 854 is available in 64
pinTQFP 68 pin PLCC, and 100 pin QFP packages.
The 64 pin package only offers the 16 mode interface,
but the 68 and 100 pin packages offer an additional
68 mode interface which allows easy integration with
Motorola processors. The XR16C854CV (64 pin) of-

XR16C854DV provides continuous interrupt output.
The 100 pin package provides additional FIFO status
outputs (TXRDY# and RXRDY# A-D), separate infra-
red transmit data outputs (IRTX A-D) and channel C
external clock input (CHCCLK). The XR16C854/
854D is compatible with the industry standard
ST16C554/554D and ST16C654/654D.
