> ICP-20100 is the latest advancement in the SmartPressure™ family
> Industry’s newest and most precise pressure sensor in a 2 x 2 x 0.72 mm package
> Suitable for smartphones, wearables, drones, and IoT markets

TDK Corporation announces the InvenSense ICP-20100 platform, the latest technology advancement in the SmartPressure™ product family. The ICP-20100 is a barometric pressure sensor based on MEMS capacitive technology, improving our lead in the development of ultra-low noise at the lowest power and progressing our industry-leading relative accuracy, sensor throughput, and temperature stability. The ICP-20100 achieves the industry’s lowest pressure noise of 0.4 Pa RMS, while attaining the industry’s lowest power consumption of 1.0 µA, and retains excellent temperature stability with a temperature coefficient of ±0.5 Pa/°C.

The ICP-20100 capacitive pressure sensor can operate over wide temperature ranges and a variety of applications, meeting US carrier requirements for 3D geolocation and emergency applications such as the enhanced 911 (E911) system, enabling mobile indoor/outdoor navigation, improved activity identification for leisure, sport and fitness purposes, and altitude-hold in drones. The sensor assists in extending battery life for “AlwaysOn” applications due to its extreme low-power consumption. Other new advancements of ICP-20100 showcase improved measurement of small pressure differences of ±0.4 Pa, thus enabling the ICP-20100 to detect altitude changes of less than 5 cm. The platform includes chipsets, developer kits, and app notes.

“The ICP-20100 expands our SmartPressure product family which includes the ICP-101xx – a combination of high accuracy, low power, temperature stability, and waterproofing in a small footprint, and the ICM-20789, the industry’s first 7-axis combo (3-axis accelerometer, 3-axis gyroscope, 1-axis pressure),” said Amir Panush, CEO of InvenSense, a TDK Group company and General Manager of TDK Corporation’s MEMS Sensors Business Group. “This latest pressure sensor technology advancement continues TDK’s lead in bringing innovative human-sensing to our OEM partners and the consumer electronics market.”

For strategic customers, InvenSense is providing samples of the ICP-20100 pressure sensor family in a 2 x 2 x 0.72 mm industry-standard package footprint; volume production is expected in 1H 2021. TDK will be demonstrating the ICP-20100 platform along with the industry’s most comprehensive portfolio of passive components, sensors, power supplies and batteries during the upcoming CES 2021 conference, being held digitally at https://www.ces.tech.
