TS3002: A 1V/1µA Silicon Oscillator/Timer IN TDFN22EP-8

The TS3002 is the industry’s first and only singlesupply CMOS oscillator fully specified to operate at 1V while consuming a 1μA supply current at an output frequency of 25kHz. This oscillator is compact, easy-to-use, and versatile. Optimized for ultra-long life, battery-powered applications, the TS3002 is Touchstone’s first oscillator in the “NanoWatt Analog™” high-performance analog integrated circuits portfolio. The TS3002 can operate from single-supply voltages from 0.9V to 1.8V.

Requiring only a resistor and a capacitor to set the output frequency, the TS3002 represents a 66% reduction in pcb area and a factor-of-10 reduction in power consumption over other CMOS-based integrated circuit oscillators. When compared against industry-standard 555-timer-based products, the TS3002 offers up to 93% reduction in pcb area and four orders of magnitude lower power consumption.

The TS3002 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, 8- pin 2x2mm TDFN package with an exposed backside paddle.
