XR16M564/564D

1.62V TO 3.63V QUAD UART WITH 32-BYTE FIFO

MAY 2008

REV. 1.0.0

FEATURES

GENERAL DESCRIPTION

•

Pin-to-pin compatible with ST16C454, ST16C554,

TI’s TL16C754B and NXP’s SC16C754B

The XR16M564 (M564) is an enhanced quad

Universal Asynchronous Receiver and Transmitter

(UART) with 32 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 M564 is available in a 48-pin QFN,

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

packages. The 64-pin and 80-pin packages only offer

the 16 mode interface, but the 48 and 68 pin

packages offer an additional 68 mode interface which

allows easy integration with Motorola processors.

The XR16M564IV (64-pin) offers three state interrupt

output while the XR16M564DIV provides continuous

interrupt output. The XR16M564 is compatible with

the industry standard ST16C554 and ST16C654/

654D.
