dsPIC33A Support Documentation
The first step in development is choosing a device and downloading basic documentation for it. This page shows you how to do this.
Parametric Search
To locate dsPIC33A design documentation, the first step is to locate a suitable device and jump to the product home page. Visit our Parametric search tool.
Using the available pull-downs in the upper-left corner, list all dsPIC33A devices by selecting Microprocessors and Microcontrollers, Digital Signal Controllers, and dsPIC33A DSC as shown. After reviewing available device features, select a device, and click on the product identifier link as shown to navigate to the product home page.
Product Home Page
The product home page is your one-stop location for all collateral and information related to your selected device. Top-level menus are conveniently located to allow you to navigate to product-specific information.
Data Sheet and Errata Documents
The product data sheet is the primary design document, containing detailed descriptions of all subsystems, as well as basic peripheral configuration code examples.
| The errata document outlines performance deviations from the device specification and, where possible, outlines firmware recommendations to mitigate the effects.

Other Design Documents
The following documents are highly recommended for those new to the dsPIC33A:
The dsPIC33A Programmer’s Reference Manual is key to understanding the low-level programming interface and assembly language instructions for dsPIC33A.
The dsPIC33CK to dsPIC33AK Migration and Performance Enhancement Guide highlights the new architectural features of the device and is particularly useful if you need to migrate existing firmware from an older dsPIC33 device.
Finally, we have the MPLAB® XC-DSC C Compiler User’s Guide, which is available online and in the documentation folder of your XC-DSC installation. This is probably the most important document for C programmers to get the most out of their C programs written for the dsPIC33A.
