DSPIC33CK128MC102-E/SS Übersicht
A Digital Signal Controller combines the deterministic compute of a digital signal processor with the peripheral integration and interrupt structure of a microcontroller. Within the power-management hierarchy of embedded systems, the DSC sits between general-purpose MCUs and dedicated DSPs, making it the preferred choice for control loops that demand both fast math (multiply-accumulate in single cycle) and rich on-chip analog and timing peripherals.
Key differentiators of this device include the 100 MHz dsPIC33CK core delivering up to 100 MIPS of deterministic performance, a high-resolution PWM module purpose-built for Field-Oriented Control (FOC) of motors, an integrated 12-bit ADC for precision current and voltage sensing, and CAN FD connectivity for automotive and industrial networking. The -E extended temperature variant guarantees operation across the full -40C to +125C automotive and industrial range.
Architecturally, the dsPIC33CK family uses a modified Harvard pipeline with DSP engine instructions, hardware looping, and bit-reversed addressing, allowing FOC loops to execute in tens of microseconds. On-chip peripherals such as the high-speed PWM with fine edge placement resolution offload timing-critical tasks from the CPU, while the CAN FD module enables modern vehicle and factory bus topologies.
Typical applications include brushless DC and PMSM motor control (FOC), digital power supplies such as LLC and totem-pole PFC converters, automotive body and powertrain auxiliaries requiring CAN FD, and industrial sensing nodes. The combination of 100 MIPS headroom and high-resolution PWM makes it especially well suited to single-chip motor control designs.
When designing with this part, use the required PGECx/PGEDx pin pairs (any pair works, but the pair must be used together) for ICSP programming, and connect all VDD/VSS and AVDD/AVSS pin pairs.

Typische Anwendungen
DSPIC33CK128MC102-E/SS ist geeignet für 6 Anwendungs: BLDC / PMSM Motor Field-Oriented Control, Digital Power Conversion (LLC, Totem-Pole PFC), Automotive Body and Auxiliary Nodes with CAN FD, Industrial Sensing and Automation Nodes, Home Appliance and Consumer Motor Control, CAN FD-Connected Embedded Control Modules.
BLDC / PMSM Motor Field-Oriented Control
The DSPIC33CK128MC102-E/SS fits FOC motor control because its dsPIC33CK core delivers up to 100 MIPS of deterministic compute for Clark/Park transforms and PI current loops, while the high-speed PWM module provides complementary outputs with high edge resolution for three-phase inverters. The on-chip 12-bit ADC samples phase currents with tight synchronization to the PWM carrier, minimizing measurement latency in the control loop. In a typical topology, the DSC drives a three-phase gate-driver stage through the PWM pins, receives amplified shunt-current feedback through the ADC inputs, and closes current loops in tens of microseconds. The trade-off versus a general-purpose MCU is DSP-class math throughput with no external controller needed, but single-chip designs must budget Flash carefully for FOC libraries within the 128KB program memory.
Empfohlen
Digital Power Conversion (LLC, Totem-Pole PFC)
Digital power supplies benefit from the DSPIC33CK128MC102-E/SS because the 100 MHz core executes voltage- and current-loop compensators deterministically, and the high-speed PWM offers the fine phase-shift and dead-time control required by LLC half-bridge and totem-pole PFC topologies. The 12-bit ADC supports fast feedback sampling synchronized to PWM events, enabling peak-current-mode and average-current-mode control strategies on a single chip. In these designs the DSC replaces analog compensation networks, allowing programmable soft-start, adaptive dead-time, and protection state machines. A key performance consideration is PWM resolution at high switching frequency; the dsPIC33CK high-speed PWM maintains fine duty-cycle granularity, reducing output ripple versus legacy DSCs, while CAN FD permits digital telemetry and configuration in server and telecom power shelves.
Empfohlen
Automotive Body and Auxiliary Nodes with CAN FD
The -E extended temperature grade (-40C to +125C) and integrated CAN FD make the DSPIC33CK128MC102-E/SS a strong fit for automotive auxiliary modules such as pump controllers, flap actuators, lighting managers, and sensor hubs operating in harsh under-hood or cabin environments. CAN FD provides 64-byte payloads and faster data phases for richer diagnostics than classical CAN, while the 100 MIPS core runs local closed-loop control autonomously between bus transactions. In a typical node, the DSC reads position or current feedback through the ADC, drives actuators via PWM, and communicates with the vehicle gateway through an external CAN FD transceiver. The extended-temperature qualification of the -E suffix supports designs targeting AEC-grade environmental envelopes, though always verify specific qualification requirements with Microchip for safety-critical programs.
Empfohlen
Industrial Sensing and Automation Nodes
Industrial automation nodes use the DSPIC33CK128MC102-E/SS where deterministic signal processing meets modest I/O count: the 28-pin 28-SSOP footprint conserves board area in dense sensor boards, while the 100 MHz DSP core performs digital filtering, FFT-based diagnostics, and calibration math on sampled sensor data. The 12-bit ADC with fast sampling converts bridge or current-sensor outputs, and SPI/I2C/UART peripherals link external precision converters, EEPROMs, and displays. The industrial -40C to +85C class of sibling -I variants allows cost-optimized factory-floor deployments, while this -E/SS covers high-temperature enclosures. Performance consideration: 128KB Flash accommodates filtering plus protocol stacks, and CAN FD enables direct attachment to industrial networks without a separate communication controller.
Empfohlen
Home Appliance and Consumer Motor Control
Fans, pumps, compressors, and small appliances increasingly use sensorless FOC on the DSPIC33CK128MC102-E/SS, replacing trapezoidal control for quieter, more efficient operation. The 100 MIPS core runs sensorless observers (sliding-mode or BEMF-based) alongside current loops, the high-speed PWM generates the three-phase drive, and the 12-bit ADC handles DC-bus and phase-current feedback. The compact 28-SSOP package suits cost- and space-constrained appliance PCBs, and the 128KB Flash holds FOC middleware plus housekeeping code. Compared with a basic MCU plus analog control, the DSC approach adds programmability for variable-load efficiency and fault diagnostics, with the trade-off of firmware complexity and the need for careful EMC-aware PWM layout in high-voltage appliances.
Empfohlen
CAN FD-Connected Embedded Control Modules
General embedded control modules that must join modern CAN FD networks - gateways, I/O expanders, diagnostic nodes - are a natural fit for the DSPIC33CK128MC102-E/SS because the CAN FD controller is integrated, eliminating an external CAN controller and reducing BOM cost and latency. The 100 MHz dsPIC33CK core provides headroom for protocol handling, application logic, and local control simultaneously, and the 12-bit ADC supports analog multiplexing of up to a dozen sensor channels into one node. In such modules the DSC sits between the CAN FD transceiver and the local actuator/driver stage, executing cyclic tasks on timer interrupts. A design consideration is transceiver selection: pair with an FD-capable transceiver such as the MCP2562FD to realize the bus speeds the controller supports.

Designhinweise
Connect ALL VDD/VSS pairs (pins 7/10/15/16) and the AVDD/AVSS pair (pins 28/27). Per Microchip documentation and the northernsoftware.com dsPIC33CK128MC102 programming guide, all VDD and VSS pins must be connected for programming and operation. Decouple each VDD with a 100 nF ceramic capacitor placed within 2 mm of the pin, and decouple AVDD through a ferrite bead from the digital rail with its own 100 nF plus 1 uF capacitor to preserve 12-bit ADC accuracy.
ICSP wiring: the dsPIC33CK128MC102 provides multiple PGECx/PGEDx pairs (pins 13/14, 22/23, 24/25, 2/3). Any pair may be used for ICSP, but the two pins of a pair must be used together - e.g., PGEC2 (ICSPCLK) must pair with PGED2 (ICSPDAT), per Microchip documentation. Mixing pins from different pairs is the most common cause of failed in-circuit programming. Route the chosen pair to a 5-pin header (MCLR, VDD, GND, PGECx, PGEDx) with series 100 ohm resistors recommended on MCLR.
When driving a three-phase inverter from the high-speed PWM outputs, keep PWM traces short and routed away from ADC input traces (pins 2-6, 11-14) to prevent switching-induced noise coupling into current-sense samples. Synchronize ADC conversions to PWM events using the built-in trigger rather than free-running sampling; this samples phase currents at the PWM center, rejecting switching ripple and improving FOC loop accuracy at high switching frequencies.
Estimated: budget the core supply for full-speed operation - dsPIC33CK-class cores at 100 MHz draw peak active current on the order of tens of mA; consult the manufacturer datasheet electrical characteristics table for the exact ICC figure and the required supply voltage range (not listed in the verified web data for this page). Provide at least 10 uF of bulk capacitance at the board supply entry plus per-pin 100 nF decoupling to handle flash-write and PWM-transition transient loads.
Compliance-Informationen
RoHS compliance stated in distributor comparison data (etei.com comparison table). Not AEC-Q100 qualified data confirmed; the -E extended temperature suffix indicates extended-range qualification but formal automotive qualification status should be verified with Microchip.
