DSPIC33CK64MC102-E/SS Overview
A Digital Signal Controller combines the computational architecture of a digital signal processor (DSP) with the peripheral integration and control-oriented ease of use of a microcontroller (MCU). Within the power-management hierarchy, the DSC sits at the top of embedded control ICs, making it a natural fit for digital power conversion, motor control, and advanced sensing systems that require deterministic, cycle-accurate real-time performance.
Key features of this device include the 100 MIPS dsPIC33CK core with DSP instructions, 64 KB of program Flash with ECC and fault-injection testing support, and 8 KB of SRAM with Memory Built-In Self-Test (MBIST). These functional-safety-oriented features support the development of robust industrial and automotive-adjacent designs. The E-temperature suffix guarantees operation from -40C to +125C ambient, while the /SS suffix identifies the extended-temperature 28-lead SSOP (5.3 mm body, 0.65 mm lead pitch) package.
On the analog side, the dsPIC33CK64MC10X family integrates 12-bit high-speed ADCs, on-chip operational amplifiers (op amps), analog comparators, and a high-resolution PWM peripheral used for Field-Oriented Control (FOC) of motors and switching power supplies. Multiple DMA channels offload data movement from the CPU, and three serial communication interfaces support UART, SPI, and I2C connectivity.
Typical applications include brushless DC and PMSM motor control (FOC), digital power supplies and LED drivers, power-factor-correction stages, sensor acquisition and conditioning, and touch or advanced-sensing interfaces. The combination of a fast ADC, op amps, and 2 ns-resolution PWM in one chip eliminates several external components in these designs.
Design consideration: the core operates from a 3.0 V to 3.6 V supply; above +125C ambient the maximum operating speed is derated to 70 MIPS (per the H-suffix operating range), so verify thermal and timing margins in high-temperature enclosures.

Typical Applications
DSPIC33CK64MC102-E/SS is suitable for 6 applications: BLDC/PMSM Motor Control (FOC), Digital Power Supplies and PFC, LED Drivers and Lighting Control, Sensor Acquisition and Signal Conditioning, Industrial Automation and Control, Touch and Advanced Sensing Interfaces.
BLDC/PMSM Motor Control (FOC)
The DSPIC33CK64MC102-E/SS fits brushless DC and PMSM Field-Oriented Control because its 100 MHz (100 MIPS) DSP core executes the FOC current loop deterministically while the 12-bit high-speed ADC samples phase currents and the high-resolution PWM (2 ns family resolution) drives the inverter gate stages with fine duty resolution. On-chip op amps can amplify shunt-current signals internally, reducing BOM cost, and analog comparators support fast overcurrent trips independent of the CPU. In a typical topology the ADC is triggered by the PWM at the center of each switching period, ensuring ripple-free current sampling; the E-grade -40C to +125C range covers industrial drive enclosures.
Recommended
Digital Power Supplies and PFC
The DSPIC33CK64MC102-E/SS suits digital AC-DC and DC-DC power conversion, including power-factor-correction stages, because its high-resolution PWM provides the fine duty-cycle granularity needed for higher switching frequencies and lower output ripple, while the 12-bit ADC closes voltage and current loops with fast, deterministic sampling at up to 100 MIPS of control bandwidth. Cycle-accurate PWM latency and comparator-based fast fault trips protect the power stage during transients. The 64 KB ECC Flash holds compensation and sequencing firmware with headroom, and the 3.0 V to 3.6 V core supply integrates cleanly into the housekeeping rail of the supply.
Recommended
LED Drivers and Lighting Control
For high-power LED drivers, the DSPIC33CK64MC102-E/SS provides high-resolution PWM dimming with fine step size for flicker-free current regulation, plus the 12-bit ADC to monitor LED current and board temperature through external sensing resistors or NTC dividers. The on-chip op amps can condition low-level current-shunt signals internally, and analog comparators deliver fast short-circuit protection without CPU intervention. Running the control loop at 100 MIPS allows switching frequencies beyond what typical general-purpose MCUs achieve deterministically, and the extended -40C to +125C rating suits sealed luminaires and industrial lighting where ambient temperatures run high.
Recommended
Sensor Acquisition and Signal Conditioning
The DSPIC33CK64MC102-E/SS is a strong fit for precision sensing nodes because the integrated 12-bit high-speed ADC digitizes sensor signals at high sample rates while the on-chip op amps provide gain and filtering in analog, eliminating external instrumentation amplifiers in many designs. Four DMA channels stream ADC results to RAM without CPU cycles, leaving the 100 MIPS core free for DSP filtering (IIR/FIR), calibration, and protocol handling across the three serial interfaces. The 64 KB ECC Flash stores multi-point calibration tables, and the MBIST-backed SRAM plus FuSa support benefit functional-safety-oriented measurement systems in industrial equipment.
Recommended
Industrial Automation and Control
In industrial automation subsystems such as actuator control, pump and fan drives, and embedded controllers, the DSPIC33CK64MC102-E/SS combines 100 MIPS of deterministic control with three serial interfaces (UART, SPI, I2C) for fieldbus and HMI connectivity. The -40C to +125C E-grade rating tolerates cabinet temperatures, and the ECC Flash with fault-injection testing plus SRAM MBIST support reliability requirements common in factory equipment. The high-resolution PWM directly drives motor or heater power stages, while comparators provide hardware-level fault shutdown. Its 28-SSOP footprint keeps controller PCB area compact inside dense I/O modules.
Recommended
Touch and Advanced Sensing Interfaces
Microchip positions the dsPIC33CK64MC10X family for touch and advanced sensing and control applications, and the DSPIC33CK64MC102-E/SS supports these by scanning capacitive-touch channels through its ADC with CPU-driven charge transfer at 100 MIPS, sustaining fast response times even while running the main control loop. The on-chip op amps and comparators additionally support inductive, resistive, and current-based sensing modalities. The 3.0 V to 3.6 V supply matches standard touch-panel rails, and the E-grade temperature range suits appliance and industrial touch panels exposed to wide environments, with 64 KB ECC Flash holding tuned touch libraries and application firmware together.

Design Notes
The dsPIC33CK64MC102 core requires a 3.0 V to 3.6 V supply. Decouple each VDD pin with 0.1 uF ceramic capacitors placed within 2-3 mm of the pin, plus one bulk 4.7-10 uF capacitor near the device. Per the device support notes, ALL VDD and VSS pins must be connected - do not leave any pair floating. If the ADC drives the control loop, consider a dedicated low-noise 3.3 V LDO for AVDD to reduce reference and analog noise.
For ICSP programming, route one complete PGECx/PGEDx pair to a standard 5-pin (MCLR, VDD, GND, PGD, PGC) programming header. Per Northern Software's dsPIC33CK64MC102 support notes, ICSPCLK and ICSPDAT must come from the same numbered pair (e.g., PGEC2 with PGED2); mixing pairs from different numbers will prevent communication. Keep the header traces short and away from PWM switching nodes.
Verify junction temperature against ambient: the E grade permits +125C ambient at full 100 MIPS operation, but at sustained high loads in sealed enclosures the effective ambient may exceed the room value substantially. Estimated: if your enclosure ambient reaches +85C and self-heating adds margin, retain at least 20C of headroom. Above +125C ambient, only the H-suffix variant (DSPIC33CK64MC102-H/SS, derated to 70 MIPS) is suitable - confirm your firmware timing closes loops at the reduced speed before switching grades.
Two frequent mistakes with dsPIC33CK parts: (1) selecting a package suffix without checking the pinout - the /2N QFN and /SS SSOP options for the same die are NOT pin-compatible, so footprint changes require PCB respin; (2) forgetting that MCLR must be pulled up (approximately 10 kohm) to VDD with ICSP access, since MCLR doubles as the programming voltage pin. Also confirm the 518-page family datasheet errata sheet for the exact device revision before tape-out.
