XR16C854/854D
2.97V TO 5.5V QUAD UART WITH 128-BYTE FIFO
REV. 3.0
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
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
TQFP, 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.
