Barometric pressure sensor platform delivers ultra-low power consumption

Announcing worldwide availability of the InvenSense ICP-20100 platform, TDK Corp.’s new generation of MEMS barometric pressure sensor platform combines a barometric pressure sensor and a temperature sensor in a 2.0 × 2.0 × 0.8-mm package. This small device targets smart phones, tablets, drones, and smart home appliances.

Thanks to a capacitive MEMS architecture, the InvenSense SmartPressure family delivers lower power consumption and lower noise than competing pressure sensors technologies, said TDK. The ICP-20100, the newest member of the pressure sensor platform, improves ON the accuracy, long term drift, and temperature stability of the product family.

Barometric pressure sensor platform delivers ultra-low power consumptionThe combo sensor solution monitors pressure changes in the range of 30 to 110 kPa and delivers accurate temperature measurements. The ICP-20100 claims the industry’s lowest pressure noise of 0.4 Pa RMS and lowest power consumption of 1.0 µA. It also offers excellent temperature stability with a temperature coefficient of ±0.5 Pa/°C.

The device offers multiple input Voltage levels including 1.2 V, 1.8 V and 3.3 V, and a choice of I²C, I3CSM, and SPI interfaces for greater design flexibility. The operating temperature range is -40°C to 85°C.

The device can be configured to achieve ultra-low-noise or ultra-low-power performance as well as in-between those specifications. With ultra-low-noise pressure sensing capabilities, the ICP-20100 can detect altitude changes of less than 5 cm. The sensor helps extend battery life for always-on applications due to its “extreme” low-power consumption, said the company.

The ICP-20100 pressure sensor can operate over wide temperature ranges and deliver measurement accuracies required by a variety of applications, including 3D geolocation and emergency location service (E911), mobile indoor/outdoor navigation, sport and fitness activity tracking, and altitude-hold in drones.

Sampling now, the ICP-20100 is available in a 10-pin LGA package. A development kit (DK-20100) and evaluation platform are available along with necessary software.
