XR16V654/654D

2.25V TO 3.6V QUAD UART WITH 64-BYTE FIFO

MAY 2007

REV. 1.0.1

GENERAL DESCRIPTION

The XR16V654

(V654) is an enhanced quad

Universal Asynchronous Receiver and Transmitter

(UART) each with 64 bytes of transmit and receive

FIFOs, programmable transmit and receive FIFO

trigger levels, automatic hardware and software flow

control, and data rates of up to 16 Mbps at 4X

sampling rate. Each UART has a set of registers that

provide the user with operating status and control,

receiver error indications, and modem serial interface

controls. An internal loopback capability allows

onboard diagnostics. The V654 is available in a 48-

pin QFN, 64-pin LQFP, 68-pin PLCC, 80-pin LQFP

and 100-pin QFP packages. The 64-pin and 80-pin

packages only offer the 16 mode interface, but the

48, 68 and 100 pin packages offer an additional 68

mode interface which allows easy integration with

Motorola processors. The XR16V654IV (64-pin)

offers three state interrupt output while the

XR16V654DIV provides continuous interrupt output.

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

XR16V654 is compatible with the industry standard

ST16C554 and ST16C654/654D.
