TCA6424A: I2C

Rajesh taalla
Prodigy 10 points
Part Number: TCA6424A

Hi,

I am looking for someone who can help me in solving this issue.

I need to connect 24 I2C sensors like VL53L1X sensors to one microcontroller.

Can I use this TCA6424A Low-Voltage 24-Bit I2C and SMBus I/O Expander to connect to a microntroller.

I am also looking for a microcontroller that can support TCA6424A.

Please help me .

Thanks

    Hey Rajesh,

    "I need to connect 24 I2C sensors like VL53L1X sensors to one microcontroller."

    How many unique addresses do you have with those sensors? Are you using only one I2C bus? If so it sounds like you need an I2C switch.

    "Can I use this TCA6424A Low-Voltage 24-Bit I2C and SMBus I/O Expander to connect to a microntroller."

    Yes.

    "I am also looking for a microcontroller that can support TCA6424A."

    The only requirement for this is a microcontroller with I2C ports (SDA/SCL) otherwise you could bit bang it. This requirement is basically met with almost all MCUs nowadays.
