PIN DESCRIPTIONS
Host Interface Pins
Serial Clock (SCL)
The SCL input is used to clock data into and out of the
X9448.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer data into
and out of the device. It is an open drain output and
may be wire-ORed with any number of open drain or
open collector outputs. An open drain output requires
the use of a pull-up resistor. For selecting typical val-
ues, refer to the guidelines for calculating typical val-
ues on the bus pull-up resistors graph.
Device Address (A0 - A3)
The address inputs are used to set the least significant
4 bits of the 8-bit slave address. A match in the slave
address serial data stream must be made with the
address input in order to initiate communication with
the X9448. A maximum of 16 devices may share the
same 2-wire serial bus.
Potentiometer Pins
VH (VH0 - VH1), VL (VL0 - VL1)
The VH and VL inputs are equivalent to the terminal con-
nections on either end of a mechanical potentiometer.
VW (VW0 - VW1)
The wiper output is equivalent to the wiper output of a
mechanical potentiometer and is connected to the
inverting input of the voltage comparator.
Comparator and Device Pins
Voltage Input VNI0, VNI1
VNI0 and VNI1 are the input voltages to the plus (non-
inverting) inputs of the two comparators.
Buffered Voltage Outputs VOUT0, VOUT1
The VOUT0, and VOUT1 are the buffered voltage
comparator outputs enabled by respective bits in the
volatile analog control register.
Hardware Write Protect Input WP
The WP pin when low prevents nonvolatile writes to
the wiper counter and analog control registers.
Analog Supplies V+, V-
The analog supplies V+, V- are the supply voltages for
the XDCP analog section and the voltage comparators.
System Supply VCC and Ground VSS
The system supply VCC and its reference VSS is used
to bias the interface and control circuits.
