1 Mapping Peripheral Capabilities When Migrating From 8-bit to 16-bit PIC MCUs Peripherals Summary When migrating from one PIC microcontroller (MCU) family to another, you get to stay within the same MPLAB ecosystem and MPLAB Code Confi gurator to minimize your learning curve and speed your application development. The PIC MCU families include fl exible, integrated peripherals that allow for fast system response time. The core independent peripherals offl oad the CPU to focus on other tasks or sleep in order to minimize power consumption. You can customize application functions with smart internal interconnections of analog and digital peripherals. Smart peripherals facilitate intelligent operations with the ability to implement simultaneous function control and self-sustaining closed loop control. This document helps decode the peripheral capabilities when migrating from 8-bit (PIC16 and PIC18) to 16-bit (PIC24 and dspic33) devices.
