STMicroelectronics – Ultra-low power, 3-axis accelerometer with 10-years longevity for industrial applications
The 10 years longevity commitment program assures, on selected parts, continuity and stability of supply for ST customers, especially those that design industrial applications and require long-term product availability. The 10 years longevity commitment begins at the time of product launch. The first MEMS joining the program are ST’s new accelerometers and a gyroscope specifically intended for harsh industrial environments often characterized by extended temperature ranges and a high level of shocks and vibrations.
IIS328DQ
The new IIS328DQ high-performance, 3-axis accelerometer is recommended for industrial applications requiring an extended temperature range and long lifespan. It features ultra-low-power operational modes that allow advanced power-saving and smart sleep-to-wakeup functions. The IIS328DQ has dynamic, user-selectable full-scales of ±2g/±4g/±8g and is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz. Available in a 4×4 mm package, the IIS328DQ is guaranteed to operate over a temperature range from -40 to +105 °C.
IIS2DH
The IIS2DH is an ultra-low-power highperformance three-axis linear accelerometer with digital I2C/SPI serial interface standard output.
The IIS2DH has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz. The device may be configured to generate interrupt signals by two independent inertial wake-up/free-fall events as well as by the position of the device itself. The self-test capability allows the user to check the functionality of the sensor in the final application.
The IIS2DH is available in a small thin plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.
