Product Overview

ICP-20100 is a high-precision, low-power barometric pressure and temperature sensor IC. It integrates a capacitive pressure sensor to accurately monitor pressure changes in the range of 30-110 kPa, equipped with a DSP module for on-chip calibration, built-in ADC, digital filtering, 96-byte FIFO buffer, and programmable interrupt functions. Supporting multiple high-speed interfaces including I²C, I3C (13CSM), and SPI, it can be flexibly configured to ultra-low noise or ultra-low power mode. The compact 2x2x0.8 mm LGA-10L package with a vent hole is RoHS and Green compliant, widely adapting to consumer electronics, IoT, and other multi-field applications, making it a high-performance choice among MEMS pressure sensors.

Key Features

• Ultra-High Measurement Accuracy: Barometric absolute accuracy of ±20 Pa (-20℃~65℃), temperature accuracy of ±0.5℃, 20-bit output data, and relative accuracy as low as ±1 Pa, meeting professional-level measurement needs.

Typical Applications

• Smartphones and Tablets: As a low-power pressure sensor, ICP-20100’s compact package does not occupy much space, and its low-power design does not affect device battery life. It can realize altitude measurement, indoor navigation assistance, and real-time weather monitoring functions, adding practical value to mobile devices.
• Wearable Sensors: For wearable devices such as smart watches and bracelets, the sensor’s ultra-low power consumption extends battery life. High-precision pressure measurement supports mountain climbing altitude tracking and motion status monitoring, and combined with temperature data, it enhances health monitoring dimensions, making it an ideal choice for wearable device sensors.
• Home and Building Automation: In smart home and building control systems, it real-time monitors indoor and outdoor pressure and temperature changes, linking air conditioners and ventilation systems to automatically adjust environmental parameters, optimize energy utilization efficiency, and help create intelligent and comfortable living and working environments.
• Weather Stations: With high-precision pressure measurement of ±20 Pa and a wide operating temperature range of -40℃~85℃, it can stably output meteorological data, adapting to professional meteorological monitoring equipment and providing reliable barometric pressure and temperature sensor support for meteorological analysis.
