DESCRIPTION
The X9440 integrates two non volatile digitally con-
trolled potentiometers (XDCP) and two voltage com-
parators on a CMOS monolithic microcircuit.
The X9440 contains two resistor arrays, each com-
posed of 63 resistive elements. Between each ele-
ment and at either end are tap points accessible to the
wiper elements. The position of the wiper element on
the array is controlled by the user through the SPI
serial bus interface.
Each potentiometer has an associated voltage com-
parator. The comparator compares the external input
voltage VNI with the wiper voltage VW and sets the out-
put voltage level to a logic high or low.
Each resistor array and comparator has associated
with it a wiper counter register (WCR), analog control
register (ACR), and eight 6 bit data registers that can
be directly written and read by the user. The contents
of the wiper counter register controls the position of
the wiper on the resistor array. The contents of the
analog control register controls the comparator and its
output. The potentiometer is programmed with a SPI
serial interface.
