1.3 Device Structure
Each part of the dsPIC30F device can be placed into one of three groups:
1. CPU Core
2. System Integration
3. Peripherals
1.3.1 CPU Core
The CPU core pertains to the basic features that are required to make the device operate. The
sections of the manual related to the CPU core include:
1. CPU
2. Data Memory
3. Program Memory
4. DSP Engine
5. Interrupts
1.3.2 System Integration
System integration functions help to:
• Decrease system cost
• Increase system reliability
• Increase design flexibility
The following sections of the manual discuss dsPIC30F system integration functions:
1. Oscillator
