16-Bit PIC® MCU Peripherals

Every 16-Bit PIC® MCU or dsPIC® device is equipped with a variety of hardware peripherals. Having an understanding of the peripheral's operations and details on their functional use can be helpful for application designers. The following table contains a list of peripherals available on the latest 16-bit PIC MCU devices. We have provided links further down on this page to descriptions of the operation and use of the peripherals as well as sample code.

The MPLAB® Code Configurator can help produce peripheral initialization code for 8 and 16-bit devices.
