MSPM0L1305: Pull-up on I2C + low power peripherals

Part Number: MSPM0L1305

Hi, 

I'd like to know if the IOs have internal pull-ups or if we need to use external pull up resistors for the I2C ? 

Also what peripherals are considered as low power ? For example for a low power application, would you recommend SPI or I2C ? 

Thank you

Geoffrey

    Hi Geoffrey

    >> I'd like to know if the IOs have internal pull-ups or if we need to use external pull up resistors for the I2C ?

    Both SDA and SCL are open-drain bidirectional and must be connected to a positive supply voltage using a pullup resistor.

    >> Also what peripherals are considered as low power ? For example for a low power application, would you recommend SPI or I2C ?

    I will select I2C because I2C can work on power domain 0 and SPI only can work on power domain 1.

    Thanks!
