DA217 Description

Short technical summary and product information.

The DA217 from MIRA is an intelligent, triaxial acceleration sensor developed using micro-machined technology. Fabricated from single crystal silicon with a DRIE process, it is protected by a hermetically sealed silicon cap. This accelerometer offers a 14-bit digital resolution and supports selectable measurement ranges of ±2g, ±4g, ±8g, and ±16g.

Key features include temperature compensation, motion detection, step counting, and significant motion detection. The device is equipped with a 32-level FIFO buffer to minimize host processor burden and supports both I2C and SPI (3-wire/4-wire) digital interfaces. Its ultra-low power consumption makes it suitable for battery-powered applications.

The DA217 is designed for mobile consumer electronics and IoT devices, featuring a compact 2x2x0.9mm LGA package. Its wide supply voltage range (1.62V to 3.6V) and operating temperature range (-40°C to +85°C) enhance its versatility in various applications.

Target applications include user interfaces for mobile phones and PMPs, display orientation control, gesture recognition, active monitoring, free-fall detection, single/double click recognition, power management, vibration monitoring, and step counting.
