Part Number: MSP432P401R

Hi Team,

From this board we are planning to create

1. 1-I2C as Slave

2. 1-I2C as Master

3. 2-I2C as Multi-Master

Whether with part number this design is possible or not ?

Hello Praveen,

It depends slightly on the package, but the MSP432P401R can support up to 4x independent I2C buses (at least 3x I2C buses on even the smallest package.) You can see this in table 3-1 of the MSP432P401R datasheet.

Thanks,

Please Let me know in MSP432P401 will support I2C multi-master ?

If yes, can you share me any demo example for this.

Hey Praveen,

MSP432P401 can be multiple I2C masters. It has 4 completely independent eUSCI_B modules that can each act as I2C bus drivers, so it can be up to 4 I2C master's at once.

Unfortunately, I don't have any code examples configuring all the modules at one, only examples showing how to configure the first module.
