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
