Ordering Information
*Add "T1" suffix for tape and reel.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

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.
Up/Down (U/D). The U/D input controls the direction of the wiper movement and whether the counter is incremented
or decremented.

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 X93154 will be placed in the low power standby mode until the device is selected once again.
