AM2612: Maximum data size for BISS encoder

Manuel Philippin

Part Number: AM2612

Hello team,

what is the maximum data size that a single channel PRU can handle in a BISS encoder input?

Are 48 bits of data supported?

Best regards
Manuel

    Our solution can support 48 bits without safety mode enabled. Following are the constraints (also documented in application available in SDK):

    BiSS-C solution uses 64-bit data frames. Total frame size must not exceed 64 bits.
    Frame structure WITHOUT Safety mode:
    Position Data + E/W(2) + CRC(6) <= 64 bits
      Therefore: single_turn + multi_turn <= 56 bits
    Frame structure WITH Safety mode:
      Position Data + E/W(2) + sign-of-life(6) + safety CRC(16) <= 64 bits
      Therefore: single_turn + multi_turn <= 40 bits

    Regards
