TechInsights cannot tell you exactly which MCU device will be the best for your specific application. But what we can do is profile some of the recent MCU releases in this table.
Choosing a microcontroller is one of the most important aspects of
early stage system design. The chosen microcontroller can determine the
starting point of the schematic design; the overall clock speed;
how many and what type of peripheral components are needed;
the instruction set or operating system that will be used; and perhaps
most importantly--the software design environment.
And how does one choose an MCU? This is a question that many systems
designers wish was an easier one to answer. When getting feedback from
the audience while preparing the Fundamentals of Microcontrollers
course, it came up as a big issue. In response to the diverse market
demand, MCU vendors have introduced many devices to address new
markets, or to improve the performance for existing applications. So
there are just too many options currently available, and any advice on
how to choose the right device for a particular application becomes

summary table looks at some of the important aspects that are
considered when a systems designer needs to choose an MCU for their
design including price, processor, serial I/O, analog peripherals, and

Some other aspects of
the microcontroller world that could be worth exploring include design
/ evaluation kits, and code compatibility.
