As indicated by the MIMXRT1050HDUG, there are two versions of the MCU. How do I determine my specific version to guide my power supply design?
Hi @Simon_CHan ,
Thank you for your interest in NXP's RT series products and for using the NXP community.
You can refer to ERR011093 in Chip Errata for the i.MX RT1050. The Errata documentation states that this issue has been fixed in A1 silicon. Therefore, the simplest method is to check the chip silkscreen for Silicon Rev: A indicates A0, and B indicates A1. If it's version B, the issue has been fixed; if it's version A, you need to control DCDC_IN/DCDC_IN_Q within the 2.8 V–3.0 V range as required by Errata.
I hope the above is helpful to you.
Best Regards
May
