16-bit PIC® MCU Peripherals
Last modified by Microchip on 2023/11/10 11:07
Every 16-bit PIC® MCU or dsPIC® Digital Signal Controller (DSC) 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 in the Peripheral Index section of this page to descriptions of the operation and use of the peripherals as well as sample code.
MPLAB® Code Configurator (MCC) can help produce peripheral initialization code for 8-bit and 16-bit devices.
