Stepping Into the 16-bit World with the Microchip 16-bit PIC24F16KA102 Family Microcontroller
One of the commonly asked questions when we move to the bigger and powerful 16-bit microcontroller is do we really need it? As the 8-bit microcontroller is already suite almost all of our needs from a simple blinking LED to more sophisticated embedded application such as robotics. Despite the debate whether to use the 8-Bit or 16-Bit microcontroller or perhaps just go straight to 32-bit microcontroller in our embedded system design, first I will show you the Microchip PIC18F25J11 (8-Bit) and PIC24F16KA102 (16-bit) basic comparison.
I use the Microchip PIC18F25J11 for the comparison as this microcontroller is considered as the 8-Bit highest end class microcontroller equipped with Microchip nanoWatt XLP technology while the Microchip PIC24F16KA102 is considered as the 16-bit entry level class microcontroller also equipped with Microchip nanoWatt XLP technology. Both microcontrollers have a build in hardware RTCC (Real Time Clock and Calendar), I2C, SPI and CTMU (Charge Time Measurement Unit) for capacitance sensing.
Now here my opinion from the electronics hobbyist perspective, things that we always consider when learning a new microcontroller are how easy to quick prototyping it on the breadboard, how much the cost and the last is the development tools to be used. From the basic comparison above you’ve noticed that for the learning purpose these two types of microcontroller are almost identical. On the other hand let’s consider the advantages of learning the 16-bit microcontroller; the PIC24F16KA102 microcontroller families share the same architecture as the well known Microchip dsPIC (digital signal controlling) microcontroller families, therefore by learning the 16-bit PIC24F16KA102 microcontroller family will open your knowledge and richer your experiences to more advance application of the embedded world system and surely you will love and enjoy it.
…to explore a new 16-bit microcontroller world… new datasheet… and …new programming… to boldly go when the only true electronics hobbyists dare to go…
On this tutorial we are going to step into the 16-bit embedded world and I will use the Microchip PIC24F16KA102 microcontroller as our learning tools. Actually Microchip has a nice product to help you quickly learn the PIC24F16KA102 families features
