Bosch BMA530

The BMA530 is an advanced, ultra-small, triaxial low-g accelerometer with digital interfaces. The sensor is suitable for low-power and demanding consumer electronics applications. The BMA530 integrates a 16 bit digital, triaxial accelerometer with range configurable to ±2g, ±4g, ±8g, ±16g, a 8 bit digital temperature sensor for an operating temperature range -40°C ... 85°C

• Compact size 1.2 × 0.8 mm² Waber Level Chip Scale Package (WL CSP), 6 pins, height 0.55 mm
• Primary digital interface with 10 MHz slave SPI (4-wire, 3-wire), 12.5 MHz I3C and up to 1 MHz I2C (Fm+)
• Sample rates (output data rates ODR): 1.5625 Hz ... 6.4 kHz (nominal)
• Programmable low-pass filtering
• Wide power supply range: analog VDD 1.62 V ... 3.63 V
• Ultra low current consumption: typ. 125 μA (in full ODR and aliasing free operation)
• Built-in power management unit (PMU) for advanced power management and low power modes
• Power on time: 1.8 ms for communication readiness
• up to 1 KB on-chip FIFO buffer for accelerometer, temperature sensor and sensor time stamps
• Fast offset error compensation for accelerometer
• Sensor time stamps for accurate system (host) and sensor time synchronization
• Two independent programmable I/O pins for interrupt and synchronization events
• On-chip interrupt engine and integrated smart features for always-on applications (e.g., activity, action, and gesture recognition) using the sensor ultra-low power domain:
  • motion detection
  • step detector
  • plug 'n' play step counter
  • orientation, flat, tilt
  • generic interrupts (three parallel instances of a highly configurable flexible interrupt)
• RoHS compliant, halogen and lead free
