STM32L476RGT which are the 5V tolerant pins? Where can I find these infomation in data sheet?

[FHopp.1]

Hello, I use for STM32 (1.8V VDD) SPI communication with an slave temperature Sensor (3.5V basic voltage, detects high at 0,7*3,5V)

SCLK =PC10

SDO = PC11

SDI= PC12

CS = PC13

For that reason I want to use an external 3.5V Pullup. But I'm not sure if this is OK for pins

PC10/PC11/PC12/PC13. Can anybody tell me if this is OK?And where I can find these information in datasheet? I already looked in the AN4899 Application note, but coulkdn't find which pins are 5V tolerant. In special if PC10/11/12/13 are 5V tolerant.

Best regards

Fabian

Hello @FHopp.1​ 

You can refer to the STM32L476xx datasheet, and see the tables:

• Table 15: Legend/abbreviations used in the pinout table 
• Table 16: STM32L476xx pin definitions table
