Pin Description
Potentiometers Pins
RH AND RL
The high (RH) and low (RL) terminals of the ISL95811 are
equivalent to the fixed terminals of a mechanical
potentiometer. RH and RL are referenced to the relative
position of the wiper and not the voltage potential on the
terminals. With WR set to 255 decimal, the wiper will be
closest to RH, and with the WR set to 0, the wiper is closest
to RL.
RW
RW is the wiper terminal, and it is equivalent to the movable
terminal of a mechanical potentiometer. The position of the
wiper within the array is determined by the WR register.
Bus Interface Pins
SERIAL DATA INPUT/OUTPUT (SDA)
The SDA is a bidirectional serial data input/output pin for I2C
interface. It receives device address, operation code, wiper
address and data from an 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.
SDA requires an external pull-up resistor, since it is 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.
WRITE PROTECT (WP)
When this pin is kept LOW, the data is written to the device
will be ignored. This pin protectS the non-volatile memory
from being overwritten.
Principles of Operation
The ISL95811 is an integrated circuit incorporating one DCP
with its associated registers, non-volatile memory and an I2C
serial interface providing direct communication between a
host and the potentiometer and memory. The resistor array
is comprised of individual resistors connected in series. At
