Pin Descriptions
Potentiometer Pins
RH and RL
RL and RH are referenced to the relative position of the
wiper and not the voltage potential on the terminals. With
WR set to 127, the wiper will be closest to RH, and with the
WR set to 00, the wiper is closest to RL.
R
W
RW is the wiper terminal and is equivalent to the movable
terminal of a mechanical potentiometer. The position of the
wiper within the array is determined by the WR.
Bus Interface Pins
SERIAL DATA INPUT/OUTPUT (SDA)
The SDA is a bidirectional serial data input/output pin for the
I2C interface. It receives device address, operation code,
wiper register address and data from a I2C external master
device at the rising edge of the serial clock SCL, and it shifts
out data after each falling edge of the serial clock SCL.
SDA requires an external pull-up resistor, since it’s an open
drain input/output.
SERIAL CLOCK (SCL)
This input is the serial clock of the I2C serial interface.
SCL requires an external pull-up resistor, since it’s an open
drain input.
DEVICE ADDRESS (A1–A0)
The Address inputs are used to set the least significant 2 bits
of the 8-bit I2C interface slave address. A match in the slave
address serial data stream must be made with the Address
input pins in order to initiate communication with the
ISL95311. A maximum of four ISL95311 devices may occupy
the I2C serial bus.
Principles of Operation
The ISL95311 is an integrated circuit incorporating one DCP
with their associated register, non-volatile memory, and a
I2C serial interface providing direct communication between
a host and the potentiometers and memory. The resistor
array is comprised of 127 individual resistors connected in
series. At either end of the array and between each resistor
is an electronic switch between that point and the wiper.
The wiper, when at either fixed terminal, acts like its
mechanical equivalent and does not move beyond the last
position. That is, the counter does not wrap around when
clocked to either extreme.
The electronic switches on the device operate in a “make
before break” mode when the wiper changes tap positions.
When the device is powered-down, the last wiper position
stored will be maintained in the nonvolatile memory. When
power is restored, the contents of the memory are recalled
and the wiper is set to the value last stored.
