XR16C854/854D

2.97V TO 5.5V QUAD UART WITH 128-BYTE FIFO

APRIL 2013

REV. 3.1.0

FEATURES

GENERAL DESCRIPTION

Added feature in devices with top mark date code of

"F2 YYWW" and newer:

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.

■

5 volt tolerant inputs

•

2.97 to 5.5 Volt Operation

Pin-to-pin compatible with the industry standard

ST16C554 and ST16C654 and TI’s TL16C554N

and TL16C754BFN

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.

•

Intel or Motorola Data Bus Interface select

Four independent UART channels

■

Data rates of up to 2 Mbps

Transmit and Receive FIFOs of 128 bytes

Programmable TX and RX FIFO Trigger Levels

Transmit and Receive FIFO Level Counters

Automatic Hardware (RTS/CTS) Flow Control

Selectable Auto RTS Flow Control Hysteresis

Automatic Software (Xon/Xoff) Flow Control

Wireless Infrared (IrDA 1.0) Encoder/Decoder

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.
