DSPIC33CK64MP502T-I/2N Overview
A digital signal controller combines the computational power of a digital signal processor with the deterministic control and peripheral set of a microcontroller. Within the power-management IC and embedded control hierarchy, the DSC sits above general-purpose MCUs for applications that need fast math and tight control loops, such as field-oriented motor control and digitally controlled switched-mode power supplies.
Key features include 100 MIPS instruction throughput (up to 100 MIPS per Microchip), three integrated operational amplifiers, three analog comparators, 12-bit high-speed ADCs, high-resolution PWM peripherals for power conversion, and a Controller Area Network Flexible Data-rate (CAN FD) interface. The dual-panel Flash supports live update firmware upgrades, and the device is positioned for functional safety (FuSa) development per distributor listings.
The dsPIC33CK architecture uses a modified Harvard design with a single 100 MHz core operating from a 3.0V to 3.6V supply, supporting operation from DC to 100 MIPS over the industrial -40C to +85C temperature range indicated by the I-grade suffix. Integrated analog (op-amps and comparators) reduces external component count in current-sense and protection circuits.
Typical applications include digital power supplies (totem-pole PFC, LLC converters), brushless DC and PMSM motor control, automotive and industrial CAN FD nodes, and high-end sensing and control systems.
Design consideration: the 28-pin UQFN (6x6) exposes the peripheral set on a limited pin count, so plan pin muxing early; the exposed pad must be soldered to a grounded copper pour for thermal and signal-integrity performance.

Typical Applications
DSPIC33CK64MP502T-I/2N is suitable for 6 applications: Digital Power Supplies (PFC / LLC), Brushless DC / PMSM Motor Control, Automotive and Industrial CAN FD Nodes, Wireless Charging and Wireless Power Transfer, LED Drivers and Smart Lighting, Advanced Sensing and Control Systems.
Digital Power Supplies (PFC / LLC)
The DSPIC33CK64MP502T-I/2N fits digitally controlled switch-mode power supplies because its 100 MHz core and high-resolution PWM deliver the duty-cycle resolution and loop bandwidth required by totem-pole PFC and LLC converter stages. The 12-bit ADC with fast sampling captures current and voltage feedback signals, while the three integrated op-amps amplify shunt-current measurements without external amplifiers, reducing BOM cost and board area. The three comparators provide hardware-based cycle-by-cycle overcurrent protection with microsecond-class response, independent of software. Implemented between the rectified input and the power stage gate drivers, the DSC closes voltage and current loops in software, enabling adaptive mode switching and programmable protection thresholds. The trade-off versus fixed-function controllers is firmware development effort, offset by full design flexibility and field firmware updates via the dual-partition ECC Flash.

Brushless DC / PMSM Motor Control
Field-oriented control (FOC) of BLDC and PMSM motors is a primary target for the dsPIC33CK family per Microchip. The 100 MHz single-cycle MAC DSP core executes Clarke/Park transforms and PI current loops comfortably inside 20 kHz-class PWM periods. The high-resolution PWM generates finely resolved three-phase gate signals, minimizing torque ripple, while the 12-bit ADC samples phase currents synchronously with PWM events. The three on-chip op-amps condition low-side shunt signals directly, and the comparators implement hardware overcurrent trips. In a compact 28-pin UQFN, a complete single-shunt or three-shunt FOC drive fits in small appliances, power tools, fans, pumps, and drones. Performance consideration: with only 28 pins, gate-drive interfaces and communication (CAN FD or UART) must be muxed carefully; the 64KB Flash accommodates full sensorless FOC firmware with headroom for field upgrades via live update.
Recommended
Automotive and Industrial CAN FD Nodes
The integrated CAN FD controller makes the DSPIC33CK64MP502T-I/2N suitable as a smart sensor or actuator node on industrial fieldbuses and 12V vehicle networks. CAN FD raises payload throughput to up to 64-byte frames at higher arbitration-to-data bit-rate ratios than classical CAN, and the DSC's 100 MIPS core processes protocol stacks plus application DSP algorithms concurrently. Typical uses include motorized actuators, battery-management slave boards, pump controllers, and gateways between CAN and other links. The -40C to +85C industrial grade covers most under-hood-adjacent and factory-floor environments, though full AEC-Q100 qualified variants should be confirmed with Microchip for direct automotive deployments. Note that the node still requires an external CAN FD transceiver, such as Microchip's ATA6563-class devices, between the DSC pins and the differential bus wiring harness.
Recommended
Wireless Charging and Wireless Power Transfer
Wireless power transfer (WPT) transmitters and receivers demand precise, high-frequency PWM with closed-loop power and foreign-object detection - a strong fit for the DSPIC33CK64MP502T-I/2N. The high-resolution PWM generates phase-shifted or frequency-modulated drive for the H-bridge inverter at 100 kHz to several hundred kHz operating points used by Qi-class systems, while the 12-bit ADC digitizes coil current, voltage, and temperature feedback. The three comparators enable hardware-fast detuning or shutdown on fault signatures, and the op-amps amplify small sense signals without extra ICs. The 64KB dual-partition Flash supports interoperability firmware covering multiple power profiles with live-update field upgrades. In a 6x6 mm UQFN, the controller fits the constrained PCB area of charging pads and compact receiver boards; the main design trade-off is firmware complexity for the WPT control stack versus fixed-function WPT ASICs.
Recommended
LED Drivers and Smart Lighting
Digitally controlled LED drivers benefit from the DSPIC33CK64MP502T-I/2N's combination of high-resolution PWM, fast analog comparators, and CAN FD communication. The high-resolution PWM provides deep dimming ratios and flicker-free dimming curves for constant-current buck or boost LED stages, while cycle-by-cycle comparator protection guards against shorted LED strings or inductor saturation. On-chip op-amps sense LED current accurately, supporting constant-current regulation without external amplifiers. CAN FD enables networked architectural and horticultural lighting systems where fixtures report status and accept dimming commands on a shared bus. The 100 MHz core also runs color-mixing and thermal-derivation algorithms concurrently with the power loop. With 64KB Flash in a 6x6 mm UQFN, one DSC covers the power stage, communication, and housekeeping of a complete smart driver; -40C to +85C operation suits outdoor luminaires.
Recommended
Advanced Sensing and Control Systems
High-end sensing nodes - such as precision pressure, flow, or inertial measurement front ends - leverage the DSPIC33CK64MP502T-I/2N's integrated analog and DSP math. The three op-amps can be configured as gain stages or filters for bridge and differential sensors, the 12-bit ADC converts conditioned signals, and the 100 MHz core executes calibration, linearization, and FFT-based analysis in firmware, replacing discrete AFE chips. The 8KB SRAM buffers waveforms for burst analysis, and CAN FD or UART links export processed results to a host. The Peripheral Trigger Generator (PTG) automates ADC sampling sequences independent of the CPU, reducing jitter and freeing MIPS for math. In a 6x6 mm 28-pin UQFN, the device suits compact industrial transmitters and handheld instruments. Trade-off: 12-bit on-chip conversion limits absolute accuracy versus external 16/24-bit ADCs, so system accuracy requirements should be budgeted first.

- Simpler single-core software model (vs DSPIC33CH64MP202-I/2N)
Design Notes
The 28-UQFN (6x6) exposed pad is the primary ground and thermal path. Connect the EP to a solid ground pour using a grid of thermal vias (typically 4-6 under the pad); do not leave the pad unsoldered even on prototypes, as floating EPs degrade ground integrity for the ADC and increase thermal resistance. Follow the Microchip family datasheet recommended land pattern and keep the 0.5 mm-pitch fan-out traces short with matched lengths for symmetrical peripheral routing.
Supply voltage must stay within 3.0V to 3.6V for the 100 MHz operating range. Decouple each VDD pin with a 100 nF ceramic capacitor placed within 2 mm of the pin, plus one bulk 4.7-10 uF capacitor near the package. When switching heavy loads on adjacent board area (common in motor-control designs sharing this DSC's power stage), add an RC filter or ferrite bead on AVDD to protect 12-bit ADC accuracy from switching ripple.
On a 28-pin package, nearly every peripheral pin is multiplexed; lock your pin-mapping (op-amp outputs, comparator inputs, PWM outputs, CAN TX/RX) before routing, and confirm against the family datasheet pin table for the MP502 device specifically. Note also the T suffix means tape-and-reel only - there is no tube option for this ordering code; order the non-T part number if tray packaging is required. The dual-panel Flash live-update feature requires reserving one flash panel, so effective contiguous application code space is less than 64KB in live-update designs.
Compliance Information
RoHS compliant and lead-free per Microchip standard UQFN finish and distributor listings. This commercial/industrial ordering code is not an AEC-Q100 automotive part; confirm qualification requirements with Microchip before automotive deployment.
