XR16M564/564D
1.62V TO 3.63V QUAD UART WITH 32-BYTE FIFO
MAY 2008
REV. 1.0.0
GENERAL DESCRIPTION
The XR16M5641 (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.
NOTE: 1 Covered by U.S. Patent #5,649,122.
