XR16C854/854D
2.97V TO 5.5V QUAD UART WITH 128-BYTE FIFO
APRIL 2013
REV. 3.1.0
GENERAL DESCRIPTION
The XR16C854/854D1 (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
trigger levels, automatic hardware and software flow
control, 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 modem serial interface controls.
System interrupts may be tailored to meet design
requirements. An internal loopback capability allows
onboard diagnostics.
The 854 is available in 64-pin LQFP, 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) offers three state interrupt
outputs while the XR16C854DV provides continuous
interrupt outputs.
The 100 pin package provides
additional
FIFO
status
outputs
(TXRDY#
and
RXRDY# A-D), separate infrared 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.
NOTE: 1 Covered by U.S. Patent #5,649,122 and #5,949,787.
