DSPIC33CK128MC102-E/2N Visão geral
A digital signal controller combines the computational throughput of a digital signal processor with the peripherals and ease of use of a microcontroller, occupying a level of the embedded hierarchy between general-purpose MCUs and dedicated DSP ICs. Within the dsPIC33C platform, the dsPIC33CK single-core family sits below the dual-core dsPIC33CH family and above the older dsPIC30F/dsPIC33F generations.
Key differentiating features include a single 100 MHz dsPIC DSC core with DSP-enhanced instruction execution, on-chip operational amplifiers that reduce external BOM in motor-control feedback paths, a 12-bit ADC for current and voltage sensing, and high-resolution PWM peripherals suited to power conversion. The extended-temperature (E) suffix supports demanding industrial environments.
The dsPIC33CK architecture integrates an internal bus architecture with multiple peripherals, including the PWM module with hardware dead-time insertion and fault protection essential to digital power and motor drive topologies. The 16KB of RAM provides headroom for control-loop state, field-oriented control (FOC) math, and communication buffers without external memory.
Typical applications span brushless DC and PMSM motor control, switch-mode power supplies and digital lighting, power factor correction stages, and sensorless FOC drives for appliances and industrial equipment.
When designing with this device, budget Flash carefully: 128KB is generous for single-motor FOC plus communication stacks, but the 28-pin package limits peripheral pin multiplexing, so verify pin map availability early.

Aplicações típicas
DSPIC33CK128MC102-E/2N é adequado para 6 aplicaçãos: Brushless DC / PMSM Motor Control, Switch-Mode Power Supplies, Power Factor Correction, Digital Lighting and LED Drivers, Industrial Automation Sensors and Actuators, Appliance Motor Drives.
Brushless DC / PMSM Motor Control
The DSPIC33CK128MC102-E/2N fits BLDC and PMSM motor control because its 100 MHz dsPIC33CK core executes field-oriented control with DSP multiply-accumulate throughput, while the high-resolution PWM module provides dead-time insertion and cycle-by-cycle current limiting essential to three-phase inverters. The 12-bit ADC samples phase currents fast enough for shunt-based FOC, and the integrated op-amps amplify shunt signals on-chip, cutting the external BOM. In sensorless drives the 128KB Flash holds the estimator, ramp, and fault-state code with headroom. Place it as the main inverter controller with hardware PWM fault inputs to the gate driver.
Recomendado
Switch-Mode Power Supplies
For digital SMPS, the DSPIC33CK128MC102-E/2N supplies high-resolution PWM with sub-nanosecond-class duty resolution and fast 12-bit ADC triggering synchronized to PWM events, enabling current-mode control loops for buck, boost, LLC, and PFC stages. The 100 MHz core closes voltage and current loops in software at frequencies adequate for digitally controlled converters, and the op-amps condition current-shunt feedback without external amplifiers. The extended -40C to +125C temperature range suits power supplies in industrial enclosures. Keep analog sensing traces away from gate-drive nodes for ADC accuracy.
Recomendado
Power Factor Correction
The DSPIC33CK128MC102-E/2N serves digital PFC by combining its fast 12-bit ADC (dual-sample capability) with the high-resolution PWM to control boost PFC stages with average-current-mode or predictive algorithms. The 100 MHz core executes the control mathematics with DSP efficiency, while 16KB RAM holds line-cycle averaged buffers without strain. Integrated op-amps accept current-transformer or shunt feedback directly. The 128KB Flash accommodates PFC control plus system housekeeping and communication, which reduces controller count in single-stage front ends. Boundary-condition protection via PWM fault inputs handles inrush and transient faults.
Recomendado
Digital Lighting and LED Drivers
LED driver designs use the DSPIC33CK128MC102-E/2N for its high-resolution PWM, which supports dimming beyond visual flicker thresholds, and its 12-bit ADC for output-current and temperature sensing loops. The 100 MHz core runs constant-current regulation plus dimming protocols such as DALI or 0-10V interfaces in firmware, with the 128KB Flash leaving room for multiple protocol stacks. The extended temperature range fits sealed luminaires. Integrated op-amps simplify current-sense front ends, and the 28-pin UQFN keeps board area small for driver modules inside lighting housings.

Industrial Automation Sensors and Actuators
In factory automation nodes, the DSPIC33CK128MC102-E/2N combines DSC throughput for filtering and FFT-based diagnostics with general microcontroller peripherals for industrial communication and I/O. The 12-bit ADC digitizes sensor channels such as pressure, position, or vibration inputs, and DSP instructions implement digital filters that improve measurement quality. Its -40C to +125C rating withstands cabinet and actuator environments. The 128KB Flash stores protocol stacks and calibration tables, while the small 6x6 mm UQFN permits embedding into compact sensor housings and actuator control boards without redesigning existing mechanicals.
Recomendado
Appliance Motor Drives
Appliance OEMs use the DSPIC33CK128MC102-E/2N for fan, pump, and compressor drives where sensorless FOC minimizes audible noise and improves energy efficiency. The integrated op-amps and 12-bit ADC deliver the current-feedback chain required by single-shunt or three-shunt sensing, and the high-resolution PWM suppresses torque ripple that causes acoustic noise. The extended temperature grade covers hot compressor compartments, and the 128KB Flash holds FOC plus housekeeping code with margin for firmware updates. The 28-pin UQFN supports cost-driven two-layer driver boards typical of volume appliance electronics.

Notas de projeto
The 28-pin UQFN package uses an exposed pad that must be soldered to a ground via array for both thermal dissipation and a low-inductance ground return; omitting the pad connection is a common cause of intermittent behavior at 100 MHz core frequencies. Decouple VDD with at least one 0.1 uF ceramic per supply pin placed within 2 mm of the pin, plus a 4.7 uF to 10 uF bulk capacitor. Verify the operating supply voltage range and current budget in the family datasheet electrical characteristics section before finalizing the regulator selection.
When using the integrated op-amps and 12-bit ADC for current sensing in motor or power applications, route shunt Kelvin connections directly to the op-amp input pins and keep the ADC reference (VREFH/VREFL) clean with dedicated local decoupling. Separate the analog ground region under the ADC/op-amp pins from PWM gate-drive return currents; a single-point ground tie near the exposed pad is a practical compromise on two-layer boards. Peripheral Pin Select allows relocating PWM outputs, so plan the power-stage pin assignment before routing.
The /E suffix denotes the extended -40C to +125C grade; do not substitute the /I grade in applications validated above +85C, even though the die is identical - derating and qualification data differ. The 28-pin package multiplexes many peripherals onto few pins: verify that your required combination of PWM, op-amp, ADC, and communication pins coexist using the Peripheral Pin Select tables in the family reference manual before committing the schematic. Migrating code between 64KB/128KB/256KB siblings requires only linker script changes.
