AM2634: AM2634 VS AM2434 WHAT IS THE MAJOR DIFFERANCE

Hey Enis, 

Thanks for your good question. First let me start with pricing. AM2434 has production pricing on ti.com while AM2634 is still only showing preproduction pricing (X-part number). Preproduction pricing is usually more expensive than production pricing, so be careful when trying to compare a production price vs a preproduction price. We can give production AM2634 pricing through our quoting system if you are interested. 

For technical differences besides the core frequency you pointed out, the main difference is that AM2634 has more real-time control peripherals and features. For example, 64-ch of high resolution (150ps) PWMs and 30-ch of 4-MSPS ADC's. So AM2634 is very well suited to real-time control applications. 

Here are some articles and application notes on some of the real-time control features we have an applications we are targeting:

Also, AM2634 also has automotive versions (https://www.ti.com/product/AM2634-Q1) have auto-qualifcation, functional safety, and 150C Tj support for automotive applications.

On the other hand, AM2434 has more industrial communication protocols and encoder performance:

I hope that helps highlight some differences with AM2634 and AM2434, but finding the right device also very much depends on your application and requirements. Hope that helps!
