dsPIC33CK Single-Core Digital Signal Controllers

dsPIC33CK DSCs are ideal for implementing math-intensive functions such as DSP filtering of sensor inputs and offer the right mix of features to address many applications.

• 100 MIPS core to handle real-time operations and system functions
• Scalable memory from 32 KB to 256 KB Flash and available in small-form-factor 28- to 80-pin packages
• CAN FD interface for robust communication and increased bandwidth
• CodeGuard™ security to protect code and One-Time Programmable (OTP) Flash (ICSP™ programming capability)
• Range of serial communication peripherals including UARTs, LIN, SPI, I²C and SENT

Target Applications:

Implement high-efficiency, high-precision variable speed, constant torque, and Field Oriented Control (FOC) motor control applications with the dsPIC33CK and its DSP engine.

• Analog integration, including high-speed Analog-to-Digital Converters (ADCs), op amps and analog comparators, to reduce BOM cost and board space
• High-resolution Pulse-Width Modulators (PWMs) with up to 16 channels to enable dual-motor control and integrated Power Factor Correction (PFC)
• Ideal for Permanent Magnet Synchronous Motor (PMSM), Interior Permanent-Magnet Synchronous Motor (IPMSM), AC Induction Motor (ACIM) and Brushless DC (BLDC) motor control

dsPIC33CK DSCs feature a DSP engine for high-speed control loop execution in demanding high-frequency power conversion applications.

• High-resolution 250 pS PWMs with the flexibility to control various power topologies
• Tightly coupled CPU, PWMs and ADCs to reduce latency and improve control loop response, leaving more CPU bandwidth for housekeeping and system functions
• Maximum analog integration including high-speed ADCs, Digital-to-Analog Converters (DACs) with programmable waveform generator, fast analog comparators and op amps
• Live update of firmware for high-availability systems that cannot afford down-time to update firmware
