概述

Description

BMA530 is a Bosch Sensortec 3-axis MEMS accelerometer. It outputs digital data (I2C or SPI) and offers selectable full‑scale ranges (roughly ±2 g to ±16 g) with low power operation. Key features include low noise, multiple power modes, and programmable data rates, plus on‑chip interrupts for activity/inactivity detection, tilt/tap gestures, etc. It runs from about 1.7–3.6 V and is packaged in a small footprint for space‑constrained designs. Typical applications: wearables, smartphones, drones, and other IoT devices requiring motion sensing, orientation, or gesture detection.

Features

Key features of BMA530 (3‑axis accelerometer):
- 3‑axis accelerometer with programmable full-scale up to ±16 g
- Programmable output data rate (ODR) from low Hz up to several kHz
- Low noise and high resolution (typical 12–14-bit performance)
- Ultra‑low power modes and multiple power states for battery life
- Interfaces: I2C and SPI
- On‑chip motion features: activity/step detection, tilt/orientation, wake‑up, and free‑fall detection
- Interrupts and FIFO/log buffering for event-driven data
- On‑chip self‑test and calibration; optional temperature sensor for offset compensation
- Small, robust package with wide operating temperature range
- 1.8 V core with compatible I/O (varies by variant; common VDD/I/O ranges)

Package

BMA530 uses a leadless LGA (chip-scale) package, typically 2.0 × 2.0 mm with 12 pins (LGA-12). Check the datasheet for variant details.
