Regarding the model number "CY9BF114NPMC-G-JNE2", we have the following two questions.

1. Is it okay to recognize that the analog power supply (AVCC and AVSS) and the digital power supply (VCC and VSS) are isolated inside the MCU?

    There was a notation on the data sheet that the potentials of analog GND and digital GND are common, but should it be separated?

    I am using the AD conversion function.

2. If I divide analog GND and digital GND, please teach us about the maximum allowable potential difference between VSS and AVSS.

Best regards.

is there any reason why you ask same question here?

Since it is duplication, please discussion in original thread.

I appreciate your comprehension for this.
