Which MCU Platform supports the best way to implement IIoT?

Most IoT applications require more than just adding a sensor to a physical object. When people talk about ‘smart objects,’ they are usually talking about the addition of an Internet-connected microcontroller (also known as an MCU).

Microcontrollers can be thought of as tiny computers that are added to any physical object or space to give it a ‘brain.’ They contain one or more computer processors, along with memory and programmable input/output peripherals — all in a single integrated circuit.
Bits: Microcontrollers are typically sold by the number of bits that they offer. This impacts the speed at which they are able to perform non-trivial computations.

RAM: RAM is a fast-access memory that does not retain data in an absence of power. All MCUs come with certain amounts of RAM, which allows your microcontroller to quickly perform various actions. The more you have, the better, but the added RAM increases the cost of the MCU.

Flash: Flash is computer memory that retains data in the absence of power. At least some of this is essential, and it’s very useful for features like offline storage.

GPIO: GPIO stands for general-purpose input/output pins. These are the pins that you will use for connecting your sensors and actuators to the MCU and the internet. The number of pins can range from one to the hundreds, depending on the microcontroller.
