ST's state-of-the-art MEMS accelerometers include analog and digital sensors featuring up to ±400g acceleration full scale and from 1.71 to 3.6 V supply voltage.
Accelerometers have advanced power-saving features that make them the ideal choice for ultra-low-power applications. These features include low-power mode, auto wake-up function and FIFO buffer that can be used to store data, thus reducing the host processor loading and system power consumption.
ST’s accelerometers are suitable for handheld portable applications such as mobile phones and PDAs, or any other application where low power consumption and reduced package size are required. The new generation of accelerometers, recently introduced by ST, makes a significant step forward in miniaturization, with packages sized only 2x2x1 mm, available with both 14 and 12-leads pinout.
ST’s portfolio also includes accelerometers for automotive applications, such as the AIS32x family, with extended temperature range and AEC-Q100 qualified, and IISxxx products, that are part of ST’s longevity program and will stay in production for ten years from the date of introduction.
H3LISxxxDL MEMS motion sensor: low-power, high-g, 3-axis digital output accelerometer
The H3LISxxxDL family of devices offers selectable full scales from 100 up to 400 g to measure very high accelerations along three axes with ultra-low current consumption (300 µA in Active mode and just 10 µA in Low-power mode) and with output data rates up to 1 kHz.
Programmable interrupts triggered by inertial events and advanced power-saving and smart sleep-to-wakeup functions further increase the devices’ versatility and the possibility to implement power reduction strategies at the system level.
All H3LISxxxDL devices are delivered in the same 3x3x1 mm, thin, plastic, land grid array package (LGA), are pin-to-pin compatible and software compatible and guaranteed to operate over an extended temperature range from -40 to +85 °C.
MEMS sensors for designs requiring long-term availability
ST launches a new series of MEMS sensors that will stay in production for ten years starting from their date of introduction. These products take part to the 10 years' longevity commitment program, which 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 first 3 sensors joining the program are two new 3-axis accelerometers (IIS328DQ and IIS2DH) and a 3-axis gyroscope (I3G4250D) specifically intended for harsh industrial environments often characterized by extended temperature ranges and a high level of shocks and vibrations.
