TPS65910: Default I2C mode

Kuan Wei Chen (Kevin Chen)

Part Number: TPS65910

Dear team,

What is the default I2C communication mode?

Can I judge the default I2C mode by PN code or other methods?

BR

    Hi Kevin,

    The expert for this device is currently out of office and will be returning on the 8th. Please accept a delay in his response.

    Best regards,

    Kevin,

    The TPS65910 is an I2C slave. The speed of I2C communication is determined by the I2C master (MCU or processor). Whatever the frequency of the SCL pin is, that directly determines the speed of I2C communication (100kbps, 400kbps, etc.)

    The I2C Characteristics table in our datasheets is sometimes referred to as "requirements" because it is required that the I2C master meets these requirements for I2C communication to work correctly. The I2C Specification is owned by NXP, and the table in the TPS65910 datasheet will either match the spec or highlight a parameter where we do not meet the spec so that there are no surprises when you try to implement I2C.

    Table 10 on page 48 of the I2C spec shows the equivalent parameters for Standard-Mode (100kHz) and Fast-Mode (400kHz), while Table 12 on page 52 shows the parameters for High-Speed Mode (Hs-mode, 3.4MHz). I did not identify any differences between the TPS65910 datasheet and the I2C spec while reviewing.
