VALUE PROPOSITION

CONFIDENTIAL

TOUCH SOLUTIONSAPPLICATIONS

• Touch UI• Auto ON/OFF• Turn on heart rate monitor (e.g.) with long touch• Activate screens on fitness trackers

ADVANTAGES• Easier mechanical construction vs. mechanical switch• Improved aesthetics• Improved lifetime

UNIQUE FEATURES• Small BOM• Low power (sub 2uA)• Auto calibration

WHY AZOTEQ• Advanced techniques to balance sensitivity on worn

and stationary devices

CONFIDENTIAL

LONG TERM ACTIVATIONAPPLICATIONS

• Wear detect• Patented technology (DYCAL) for long term activation• Can compensate for temperature changes.• Long duration touches at low power sampling rate

UNIQUE FEATURES• Small BOM• Low power • Auto calibration

WHY AZOTEQ• Competition is temperature sensitive, so can not support long

duration touch.

POSITION AGAINST COMPETITION• Power consumption

• From 2uA (1 channel LP mode) upwards• All devices switches to NP mode when activity is detected• Especially important in battery powered devices

• Sensitivity• Highest Sensitivity means less constraints on PCB layout, overlay material,

assembly tolerance, EMC immunity• Single sided ITO reduces system cost (IQS266)• Auto Tuning• Standalone approach – no FW development, no risk• Smart algorithms to compensate for temperature changes• Dedicated FAE support

• Azoteq will assist customers with their SCH & PCB
