SYMBOL
BRIEF DESCRIPTION
1INC
Increment (INC). The INC input is negative-edge triggered. Toggling INC will move the wiper and either increment or
decrement the counter in the direction indicated by the logic level on the U/D input.
2U/D
Up/Down (U/D). The U/D input controls the direction of the wiper movement and whether the counter is incremented or
decremented.
3RH
RH. The RH and RL pins of the X93155 are equivalent to the end terminals of a variable resistor.
4VSS
Ground.
5NC
No Connection (or can be connected to any voltage between VSS and VCC.)
6RL
RL. The RH and RL pins of the X93155 are equivalent to the end terminals of a variable resistor.
7CS
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 X93155
will be placed in the low power standby mode until the device is selected once again.
8VCC
Supply Voltage.
