Dear Kinetis Community Team,

 

Customer is considering using the Kinetis E series.

 

He is reading the following data sheet of the Kinetis E series.
http://www.nxp.com/docs/en/data-sheet/MKE02P64M40SF0.pdf


The absolute rating of VIN is (Vdd + 0.3) V in "Table 2. Voltage and current operating ratings" in "4.4 Voltage and current operating ratings" on page 7 of the data sheet.
However, when looking at "Table 3. DC characteristics" in "5.1.1 DC characteristics" on page 8 of the data sheet,
Symbol " IIC (DC injection current)" is described as " VIN < VSS, VIN > VDD" , And the following values are rated:
- Single pin limit: min -2 mA, max 2 mA
- Total MCU limit, includes sum of all stressed pins: min -5 mA, max 25 mA

 

[Customer's Requirement]
Customer wants to apply 5V to the analog pin before supplying power to VDD and VDDA.

 

[Question]
Is it possible to satisfy Customer's Requirement by following the above ”IIC (DC injection current)" rating?


Best Regards,
Yasushi Hasegawa
