Accelerometers for MAX32664C
Options for Accelerometers
  • MAX32664C requires accel data to compensate for HR measurement
  • There are 2 options for feeding accel data to MAX32664C
    1. Option 1: MAX32664C can control the accel.
      • There are 2 options for accel part numbers, to be configured.  
          1. Kionix (RoHM) KX122
          2. ST Micro LIS2DS12
    2. Option 2: Host MCU can control the accel and feed the accel data to MAX32664C as described in the MAX32664 User Guide rev 3.



FAQ
  • Q: What does it mean that KX122 is NRND?
    • A: Kionix (RoHM) doesn’t want to support this part number for 10 years of life time, therefore doesn’t recommend it for new designs (NRND). Please note that company doesn’t communicate any end of life (EOL) information. Company accepts orders.
  • Q: Where can I find documentation for accel connection to MAX32664C?
  •   A: SPI bus MAX32664C (MAX86141/40 30.13.0+)  to Accel schematic is the next slide
  •    A: SPI bus MAX32664C (MAXM86146 33.13.0+)  to Accel schematic is this slide set
    •        A: I2C bus MAX32664C (MAXM86161 32.13.0+) to STM Accel schematic is in this slide set.
  • Q: Are there any other Accel part numbers supported besides KX122,  LIS2DS12?
    • A: No, but the host may pipe in accel data according to the MAX32664 User Guide. Do not connect both KX122 and LIS2DS12 to the SH.
