32.768 kHz oscillator module consumes less power

Micro Crystal is offering its popular oscillators in an advanced tiny package measuring just 1.2- x 2.0- x 0.7-mm.

This hermetically sealed package hosts the integrated circuit together with the XTAL. It withstands harsh environmental condition. Aside the large supply voltage range it features very low power consumption. In active mode it draws as low as 1 μA driving one CMOS load. Since the oscillator is running also in stand-by mode (i = 0.45 μA) the accurate frequency is available instantaneously, no delayed startup time, as typical e.g., for AT-oscillator, must be cared for. Through factory calibration the accuracy is superior to solutions with external XTAL.

The wide supply voltage range of 1.6 to 5.5 V combined with the large operating temperature range of -40°C to + 85°C, low power consumption and small package size makes it ideal for future applications such as wearables and activity bands, IoT, smart pens, industrial computing, healthcare devices, automotive, remote keyless entry systems...

The table below depicts some of the models available.
