LP-AM263P: RDC module queries

MK

Part Number: LP-AM263P

Tool/software:

Team,

Can you help us with the following questions on the RDC module in AM263P?

  1. RDC input to the MCU should be single ended or differential ?Can we connect amplified RDC single
    ended SIN and COS output to RDC block? .Whether the interface circuit mentioned here(AM2632P
    TRM) providing differential output by amplifying differential input?
  2.  Is there any separate RDC EVK and Booster pack board available to connect with LP-AM263P
    Launchpad? Since the MCU used in LP-AM263P is a Non resolver package.

Best Regards,

Madhurya

    The RDC in AM263P can accept both Single ended and differential inputs. Please refer to Section 7.5.3.2.2.1.1 Sequencer and RDC Modes of Operation of AM263Px Sitara Microcontrollers Technical Reference Manual (Rev. D) for more details. External analog front end needs to be used to ensure the Sine and Cosine inputs match the max input levels of AM263P RDC.

    For the AM263P-ZCZ-S package, please refer to the EVM TMDSCNCD263P

    There are no Boosterpack or Launchpads intended for Resolver evaluation.
