Looking for MCU having 2× MDIO interfaces,3× I2C bus interfaces

[Ganapriya]

I am currently evaluating microcontroller options for our project and need your support in identifying a suitable MCU.
Our key interface requirements are as follows:

  2× MDIO interfaces,3× I2C bus interfaces

If you could recommend an MCU that supports these features or share any relevant technical details/datasheets, it would be very helpful.
If not, please also suggest alternate part numbers that can meet this requirement.

Hello @Ganapriya and welcome to the ST community,

You can use MCU finder downloadable from this link. Or CubeMx downladable from here to find tune your finding.

Meanwhile, to my knowledge no STM32 microcontroller currently offers two native MDIO interfaces. Only one MDIO (slave only) is available for example on STM32H7 and 4xI2C are available.

Hi,

  We need MCU which has pins of 64 and 100 pins and supports I2C on STM32H7. Can you suggest the extract part number from this series?

That depends also on the RAM%/Flash size/Max frequency to optimize the price.

For 64/100 pins and using CubeMx tool, these are the part numbers proposed for only LQFP64 and LQFP100 with their corresponding unit price for 10kU:

You need to fine tune your choice by reading the product datasheet based on the flash size and the memory size and your application needs. 

For example for the case of STM32H742 (DS12110), the internal memory sizes (Flash and SRAM) change according to the part number:

.

All the part numbers listed in this datasheet have one MDIO slave instance:

And four I2C instances:

The ordering information chapter gives more information about the part number:

Hope that I've answered your question.

Hi,

Suggest me MCU which has MDC/ MDIO, I2C and 64 pins Package.
