Hi team,
Regarding SCL and SDA input voltage, 6.3 Recommended Operating Conditions says as below.
Voltage on I2C interface, Standard (100 kHz), Fast (400kHz), Fast+ (1 MHz), and High-Speed (3.4 MHz) Modes : 1.95V
Voltage on I2C interface, Standard (100 kHz), Fast (400kHz), and Fast+ (1 MHz) Modes : VANA with 3.6-V maximum
Q1: Does 1.95V only apply for High-Speed mode? For Standard and Fast, can we input 3.6V to SCL, SDA pin?
Q2: Let me check meaning of "VANA with 3.6-V maximum". Does it mean when we use I2C I/F, we should keep VANA below3.6V? or Does it mean that if the voltage of I2C terminal is below 3.6V, VANA>5V is OK ?
Best regards,
