FDC2214EVM: Addressing

Part Number: FDC2214EVM
Other Parts Discussed in Thread: FDC2214

Hi,

I was just wondering if there is anyway to set the device address of the FDC2214, I see it only has 2 addresses available, but I was hoping there was possibly a way to configure the device address so that we could utilize more than 2 FDC2214s on one I2C line.

Thanks,

Isaac

    Hi Isaac,
    Theoretically it is possible to control multiple devices from one I2C line. But allow me some time to check if it's possible to do the same with FDC2214.

    Hi Isaac,
    It is possible to setup 2 FDC2214s on one I2C line, but you can't configure any more than that. As you can see from the datasheet section 7 Pin Functions table, when ADDR is low, I2C address is 0x2A and when ADDR is high, I2C address is 0x2B. You can't configure or add more addresses. If you wish to add more than two devices to the same I2C line, you will need an I2C expander. I hope this helps!
