XR16V564/564D
2.25V TO 3.6V QUAD UART WITH 32-BYTE FIFO
MAY 2007
REV. 1.0.1
GENERAL DESCRIPTION
The XR16V564
1
(V564) 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 V564 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 XR16V564IV (64-pin) offers three state interrupt
output while the XR16V564DIV provides continuous
interrupt output. The XR16V564 is compatible with
the industry standard ST16C554 and ST16C654/
654D.

Address data lines [2:0]. These 3 address lines select
one of the internal registers in UART channel A-D dur-
ing a data bus transaction.
Data bus lines [7:0] (bidirectional).
I/O
I
When 16/68# pin is HIGH, the Intel bus interface is
selected and this input becomes read strobe (active
low). The falling edge instigates an internal read cycle
and retrieves the data byte from an internal register
pointed by the address lines [A2:A0], puts the data
byte on the data bus to allow the host processor to
read it on the rising edge.
When 16/68# pin is LOW, the Motorola bus interface is
selected and this input is not used and should be con-
nected to VCC.
When 16/68# pin is HIGH, it selects Intel bus interface
and this input becomes write strobe (active low). The
falling edge instigates the internal write cycle and the
rising edge transfers the data byte on the data bus to
an internal register pointed by the address lines.
When 16/68# pin is LOW, the Motorola bus interface is
selected and this input becomes read (logic 1) and
write (LOW) signal.
When 16/68# pin is HIGH, this input is chip select A
(active low) to enable channel A in the device.
When 16/68# pin is LOW, this input becomes the chip
select (active low) for the Motorola bus interface.

When 16/68# pin is HIGH for Intel bus interface, this
(OD) ouput becomes channel A interrupt output. The output
state is defined by the user and through the software
setting of MCR[3]. INTA is set to the active mode when
MCR[3] is set to a logic 1. INTA is set to the three state
mode when MCR[3] is set to a logic 0 (default). See
MCR[3].
When 16/68# pin is LOW for Motorola bus interface,
this output becomes device interrupt output (active
low, open drain). An external pull-up resistor is
required for proper operation.
O
When 16/68# pin is HIGH for Intel bus interface, these
ouputs become the interrupt outputs for channels B, C,
and D. The output state is defined by the user through
the software setting of MCR[3]. The interrupt outputs
are set to the active mode when MCR[3] is set to a
logic 1 and are set to the three state mode when
MCR[3] is set to a logic 0 (default). See MCR[3].
When 16/68# pin is LOW for Motorola bus interface,
these outputs are unused and will stay at logic zero
level. Leave these outputs unconnected.
Transmitter Ready (active low). This output is a logi-
cally ANDed status of TXRDY# A-D. See
Table 5.
If
this output is unused, leave it unconnected.
Receiver Ready (active low). This output is a logically
ANDed status of RXRDY# A-D. See
Table 5.
If this
output is unused, leave it unconnected.
