Increment (INC)
capacitance value and either increment or decrement the counter in the direction indicat-
ed by the logic level on the U/D input.
Up/Down (U/D)
. The U/D input controls the direction of the trimmed capacitor value and
whether the counter is incremented or decremented.
Ground
.
. The INC input is negative-edge triggered. Toggling INC will move the

minals of a mechanical trimmable capacitor. The minimum dc voltage is V
maximum is V
CC
. The value of capacitance across the terminals is determined by digital
inputs INC, U/D, and CS.
Cm
. The high (Cp) and low (Cm) terminals of the X90100 are equivalent to the fixed ter-
minals of a mechanical trimmable capacitor. The minimum dc voltage is V
maximum is V
CC
. The value of capacitance across the terminals is determined by digital
inputs INC, U/D, and CS.
Not Connected
. Must be floating.
Chip Select (CS)
. The device is selected when the CS input is LOW. The current counter
value is stored in nonvolatile memory when CS is returned HIGH while the INC input is
also HIGH. After the store operation is complete the X90100 will be placed in the low
power standby mode until the device is selected once again.
