Increment (INC). The INC input is negative-edge triggered. Toggling INC will move the capacitance value and
either increment or decrement the counter in the direction indicated 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.
Cp. The high (Cp) and low (Cm) terminals of the X90100 are equivalent to the fixed terminals of a mechanical
trimmable capacitor. The minimum dc voltage is V SS and the 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 terminals of a mechanical
trimmable capacitor. The minimum dc voltage is V SS and the 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.
