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

Hi Yasushi,
It's ok for KE to apply 5V to the analog pin before supplying power to VDD and VDDA (should be 5V too), while the current is limited within the DC injection current ranges.
