7.1  Mid-Range PIC Architecture

In Chapter 6 we analyzed the three major PIC families of 8-bit devices. From the descriptions and functionality one can see that as the PIC architecture increases in complexity and power, so does the size, intricacy, and cost of the devices. For the embedded systems covered in this book, the PICs of the mid-range family provides sufficient power and functionality. It can be argued that the baseline PICs do find extensive use and are quite practical for many applications; in fact, some of the embedded systems covered in the text could have been implemented with baseline devices. On the other hand, the baseline PICs are quite similar in architecture and programming to their ...
