AM263P2: AM263P2 -Resolver Interface and PMIC and DAL B Support

Hi Jayakeerthana,

Is there any reference design available for scaling resolver input signals to 3,3v to provide it to the AM263P2 processor?

As mentioned on  AM263P4-Q1: Arm-based microcontrollers forum 

Please refer to the reference designs for simple implementations. Also, any other analog front-end ICs can be used to scale down the Sine and Cosine signals to 3.3V level needed for RDC.

• TIDA-01527
• Resolver section of TIDM-02014

And whether AM263P2 is a DAL-B Compliance?

As mentioned in AM263P datasheet, the AM263P MCU is

Functional Safety Compliant - AM263Px TÜV SÜD Functional Safety Certificate

• Up to SIL 3 for Hardware integrity and systematic capability according to IEC 61508 / EN IEC 61508
• Up to ASIL D for Hardware integrity and systematic capability according to ISO 26262.

I am sorry but I am not aware of DAL-B compliance.

Can you please suggest a PMIC for AM263P series

For PMIC reference, we would suggest TPS653860-Q1. Please refer to TMDSCNCD263P for implementation details.

Thanks,

Hi Jayakeerthana, 

While the development of AM263Px has been done in compliance with ISO 26262/ IEC 61508 (both of which share a close similarity with the DO-254 process compliance), we haven't pursued a separate DAL-B certification for AM263Px for DO-254 compliance.

You may, however, still analyse the residual FIT details of the AM263Px device from the quantitative safety analysis reports for any evaluation.
