Module selection for ADC application

I would like to start developing an application around a MXP board, but I'm having trouble selecting a specific compute module I can use. I'm a bit overwhelmed by the variety and unsure about which products can actually do what I need.

My understanding is that there are multiple SOCs that offer ADCs. I need something with higher compute power, and at least 4 ADC channels. Which specific development boards can I use, and which modules and boards can I use to build this application? Is there a supplier who can assist me selecting the specific boards I can purchase?

Re: Module selection for ADC application

I believe an MPU to ensure there's enough processing power, plus we are not so much worried about power consumption or cost. We are also interested in being able to use Profinet. And then it should have at least 4 ADC channels with more than 100ksps (per channel). My understanding is that an i.MX 9 MPU might fit.

One alternative on my mind would be getting a Raspberry Pi Pico with a separate ADC module and Ethernet module. But I suspect an NXP system should be able to offer everything I need. But there's such a variety of products even if I settle for a specific chip, and it's often unclear if I'll get a suitable ADC, which is the most important feature of all for me.

Hello,

What are you looking for?
is it an MCU? an MPU?
We can help you with that if you can provide more information about the project.

Also, we have a product search in the webpage

Re: Module selection for ADC application

Hello,

Yes, any of the i.MX9 familly should be usable, it would depend of the graphics and other peripherals which one should be better on your use case.

For this the i.MX91, i.MX93 & i.MX95 all three have FRDM boards and have the same specs on the ADC:
• It includes eight channels, four of them connected to pins in the package.
• Support the 1MS/s frequency of operation
• Multiple modes of starting conversion (Normal, Injected)
Normal mode supports One-Shot and Scan (continuous) conversion
Injected mode supports One-Shot conversions only
• Support TRGMUX to allow 16 trigger channels to be used by any ADC channel

Also, you may have a look the the EVKs for each one but as you have mentioned RPI I think the FRDM boards would be of interest for you.
