DSPIC33CK128MC506-E/PT 概要
A digital signal controller combines the computational throughput of a DSP with the peripheral integration and control architecture of a microcontroller. Within the embedded-system hierarchy, the DSC sits between a general-purpose MCU and a dedicated DSP, making it the preferred device class for closed-loop control loops that require both fast math execution and rich on-chip analog and timing peripherals. The dsPIC33CK family represents Microchip's single-core, 100 MHz generation of this device class.
Key features include an integrated DSP engine with single-cycle MAC and dual 40-bit accumulators, on-chip operational amplifiers, a 12-bit high-speed ADC, high-resolution PWM peripherals, and CAN FD connectivity for automotive and industrial networks. These peripherals offload deterministic control tasks from software, reducing interrupt latency in time-critical loops.
Architecturally, the DSPIC33CK128MC506 uses a modified Harvard pipeline running at up to 100 MIPS, with hardware division and DSP multiply-accumulate instructions. The 128 KB of Flash supports self-programming and firmware field updates, while the 16 KB RAM accommodates control variables, filter histories, and communication buffers for motor-control and digital-power algorithms.
Typical applications include brushless DC and PMSM motor control, digital power supplies (LLC, totem-pole PFC), solar inverters, and industrial sensing nodes requiring CAN FD backhaul. The combination of high-speed PWM and fast ADC sampling suits sub-100 kHz switching power stages with cycle-by-cycle current limiting.
For design, budget the ADC sampling and PWM update timing so control-loop jitter stays below one PWM period, and verify the -40C to +125C (E-grade) temperature derating on Flash endurance in your end application.

主な用途
DSPIC33CK128MC506-E/PT の用途: 6 件s: Brushless DC and PMSM Motor Control, Digital Power Supplies (LLC and Totem-Pole PFC), Solar String Inverters and Energy Storage, Industrial Sensing and Condition Monitoring Nodes, Automotive-Adjacent Pumps, Fans, and Actuators, Networking Gateways and Embedded Control Heads.
Brushless DC and PMSM Motor Control
The DSPIC33CK128MC506-E/PT fits motor control because its 100 MHz core executes field-oriented control (FOC) loops well inside one PWM period, while high-speed PWM peripherals generate complementary outputs with dead-time insertion in hardware. The integrated op-amps condition shunt-based phase current measurements without external amplifier ICs, and the 12-bit ADC provides synchronized sampling for dq-axis current reconstruction. In a typical 48 V BLDC drive, the controller closes current loops at 20-50 kHz and speed loops at 1 kHz, with CAN FD handling command traffic from the host. The 128 KB Flash accommodates FOC algorithms, parameter identification, and a Modbus or CANopen stack simultaneously. The E-grade -40C to +125C range suits industrial drive enclosures where ambient temperatures approach 85C.

Digital Power Supplies (LLC and Totem-Pole PFC)
Digital power conversion benefits from the DSPIC33CK128MC506-E/PT's fine-resolution PWM edges and fast ADC triggering, which together support cycle-by-cycle current limiting in 65-500 kHz LLC and totem-pole PFC stages. The 100 MIPS DSP engine computes the control law - typically a PID or 3P3Z compensator - within a single switching period, avoiding loop delay that degrades phase margin in high-bandwidth converters. Integrated op-amps amplify current-transformer or shunt signals, saving board area in compact AC-DC designs. Burst mode, phase shedding, and soft-start profiles are implemented in firmware, letting one hardware platform serve multiple power ratings. With 128 KB Flash, multiple converter firmware images and diagnostic logging coexist on-chip, and the E temperature grade covers power-supply internal ambients up to 105C with margin.
おすすめ
Solar String Inverters and Energy Storage
In solar string inverters and battery energy-storage converters, the DSPIC33CK128MC506-E/PT runs MPPT (maximum power point tracking) algorithms on its 100 MHz core while simultaneously closing the grid-side current loop with the high-speed PWM and 12-bit ADC. The CAN FD interface implements CAN 2.0/FD battery-management communication to string inverters' storage packs, a common requirement in ESS architectures. The 128 KB Flash holds MPPT scheduling, anti-islanding protection, and grid-code compliance tables, and the 16 KB RAM supports running averages and notch-filter histories for grid harmonic compensation. The -40C to +125C rating matches outdoor NEMA enclosure conditions, and hardware PWM fault inputs provide nanosecond-scale shutdown on overcurrent events independent of software latency.
おすすめ
Industrial Sensing and Condition Monitoring Nodes
Industrial condition-monitoring nodes use the DSPIC33CK128MC506-E/PT to sample vibration, current, and temperature channels through the 12-bit ADC at kilohertz rates, execute FFT or RMS computations on-chip via the DSP MAC instructions, and forward condensed health metrics over CAN FD or UART to a SCADA gateway. The integrated op-amps buffer low-level sensor signals, and the 128 KB Flash stores calibration tables and feature-extraction code alongside the communication stack. Because computation happens at the edge, the network carries kilobits of results instead of megabytes of raw waveforms, reducing bus loading. The E-grade temperature range and surface-mount 64-TQFP package support DIN-rail and motor-junction-box installations exposed to -40C cold starts and sustained +85C ambients.

Automotive-Adjacent Pumps, Fans, and Actuators
Electric water pumps, cooling fans, and throttle actuators in commercial vehicles and off-highway equipment require -40C to +125C rated controllers with deterministic motor control and robust networking - a profile matched by the DSPIC33CK128MC506-E/PT. The device closes sensorless FOC loops using its 12-bit ADC and integrated op-amps, drives the three-phase bridge with hardware dead-time PWM, and reports diagnostics over CAN FD. The 100 MHz core executes position-estimation observers (sliding-mode or flux-linkage based) without external co-processors. Its 128 KB Flash supports functional-safety logging and multiple actuator firmware variants on one platform. Designers should verify the applicable AEC-Q100 qualification level with Microchip for direct in-vehicle placement, as this E-grade part is positioned for automotive-adjacent and off-highway zones.
おすすめ
Networking Gateways and Embedded Control Heads
Embedded control heads and protocol gateways leverage the DSPIC33CK128MC506-E/PT's combination of CAN FD, multiple UART/SPI/I2C ports, and a 100 MHz core to translate between fieldbus and local device networks. The 128 KB Flash hosts dual protocol stacks plus an in-field bootloader, and the 16 KB RAM buffers message queues for bursty traffic aggregation. The 12-bit ADC and integrated op-amps let the same device monitor local analog points such as bus voltage and enclosure temperature, consolidating I/O in one chip. The 64-TQFP package supplies enough general-purpose I/O for relay drive and status indication. Its E-grade temperature rating and RoHS-compliant, surface-mount construction suit industrial control panels where uptime targets exceed 50,000 hours.

設計ノート
Decouple every VDD pin pair with 100 nF X7R ceramic capacitors placed within 2 mm of the pins, plus at least one bulk 10 uF capacitor near the package. Connect all VSS pins to a solid ground plane through short vias; do not share a single thermal-relief via chain across multiple ground pins. Route the high-speed PWM outputs away from ADC input traces to prevent switching edges from coupling into current-sense channels, which would corrupt FOC feedback.
Estimated: at 100 MHz the dsPIC33CK core draws on the order of tens of milliamps; verify the exact IDD figure in the manufacturer datasheet electrical characteristics table before sizing your 3.3 V regulator. Add margin for simultaneous peripheral loading (ADC, op-amps, CAN FD) and select a regulator with at least 2x worst-case headroom to handle Flash-write current spikes during self-programming.
Confirm configuration-word settings (oscillator source, watchdog, code protection) match your programmer project file - mismatched config bits are the most common bring-up failure on dsPIC33 devices. When migrating between Flash-size variants of the MC506 family, rebuild rather than re-flash: linker memory maps differ. Also verify -40C to +125C (E-grade) Flash retention/endurance specifications in the datasheet if the product must endure sustained high-ambient operation.
