Supported Devices
The MCHP Blockset supports a wide range of Microchip microcontrollers and digital signal controllers across multiple families.
dsPIC33A Family (32-bit Digital Signal Controller with FPU)
dsPIC33A (Latest Generation - 32-bit Architecture)
| Series | Architecture | Example Devices | Key Features | Compiler |
|---|---|---|---|---|
| dsPIC33AK | 32-bit with FPU | 33AK128MC106, 33AK512MPS512, 33AKV512GMS510 | Hardware FPU, Advanced PWM with FEP, 12-bit ADC, Enhanced Security, ISA v3 | XC-DSC v3.30+ |
Important: dsPIC33A is fundamentally different from other dsPIC families - it features a 32-bit architecture with hardware floating-point unit (FPU), providing 10-100x faster performance for floating-point operations compared to traditional 16-bit dsPICs. This makes it ideal for advanced motor control and digital power applications requiring real-time floating-point computation.
