STK8BA53 Description

Short technical summary and product information.

The STK8321 is a compact, low-profile 3-axis linear accelerometer from SENSORTEK, featuring a digital I2C output. This MEMS sensor offers dynamically selectable full-scale ranges of ±2g, ±4g, or ±8g, with a 12-bit data output resolution. It is designed for low voltage operation, with an internal domain voltage range of 1.7V to 3.6V and an I/O voltage range of 1.62V to 3.6V.

The device is housed in a small 2.0mm x 2.0mm x 1.0mm LGA package, making it suitable for space-constrained applications. It guarantees operation over an extended temperature range from -40°C to +85°C. The STK8321 includes an on-chip interrupt controller for motion-triggered signal generation, supporting features like new data alerts, any-motion detection, and significant motion detection. Its high shock survivability of 10000g makes it robust for demanding environments.

Applications for the STK8321 include display orientation, gaming and virtual reality input devices, impact recognition and logging, vibration monitoring and compensation, pedometers, activity trackers for fitness apps, and smart power management for mobile devices.
