Global semiconductors specialist, ST Microelectronics introduces a range of three-axis high-resolution accelerometers with two embedded finite-state machines.
ST Microelectronics is a leading supplier of MEMS (Micro-Electro-Mechanical Systems) for consumer and portable applications.
ST’s new MEMS accelerometers are programmable blocks, which enable custom motion recognition inside the sensor, raising the bar in reducing system complexity and power consumption in motion-sensitive mobile phones and smart consumer devices that let users perform various actions with a defined motion.
With these embedded finite-state machines, users can now implement customised motion-detection-based applications with a high level of flexibility, reducing the workload of the microprocessor by moving programming functionality inside the sensor.
These basic programs identify specific motions or gestures, custom-defined in the instruction set that runs inside the sensor firmware, and initiate associated actions or applications.
According to Benedetto Vigna, Corporate Vice President and General Manager of ST’s Analog, MEMS and Sensor Group, integrated processing capability in MEMS sensors decreases power consumption at the system level, which is especially crucial in battery-hungry portable devices.
Programmable state machines embedded in the sensor also bring more freedom and flexibility to the design of motion-enabled consumer electronics.
The new LIS3DSH three-axis linear accelerometers with embedded finite-state machines leverage the same micromachining technology process that ST has successfully applied to more than 1.6 billion motion sensors already in the market.
Key features of ST’s LIS3DSH accelerometers:
- Provides extremely accurate output across full-scale ranges of ±2g/±4g/±8g/±16g
- Excellent stability over time and temperature
- Power-down and sleep modes
- Embedded FIFO (first-in first-out) memory block
- Temperature sensor
- Self-test function
