LMK04832: Absolute rating for SPI pins

Taketo Sato

Part Number: LMK04832

Hello team,

Could you let me know absolute maximum voltage/current rating for SPI pins?

I would like to confirm LMK04832 will get damaged if SPI pins sees 1.8V overvoltage but current is limited within 700uA.

Best regards,

Hello Sato-san,

i need to check that internally and will come back to you as soon as I have a confirmation.

Hi Sato-san,

we can not allow the 1.8V overvoltage. Even with limited current that will potentially damage the device.

Please make sure you stay below the absolute maximum ratings.

regards,

Julian

Hello Julian-san,

Thank you for the comment.

For maximum rating for the SPI pins, should I refer to "VIN", -0.3V to Vcc+0.3V?

Can we refer "VIN" for also SDIO pin?

Hi Sato-san,

correct. VIN describes all input voltages to the device (also logic).

Julian
