DSPIC33CK64MP202-E/2N 概要
A digital signal controller combines the compute architecture of a microcontroller with the mathematical acceleration of a DSP, sitting in the hierarchy between general-purpose MCUs and full DSPs within the broader embedded processor category. The dsPIC33CK core executes one instruction per cycle with DSP multiply-accumulate and divide support, making it well suited to closed-loop control algorithms such as field-oriented motor control and average-current-mode power conversion.
Key features of the DSPIC33CK64MP202 include the dual-panel flash architecture that allows live firmware updates while executing from the alternate panel, up to 3.5 Msps 12-bit ADC operation for fast current sampling, integrated operational amplifiers that offload external signal conditioning, and high-resolution PWM peripherals with dead-time control for bridge topologies. The -E extended temperature grade and Functional Safety (FuSa) support documented by distributors make the device suitable for demanding industrial environments.
Technically, the 100 MHz dsPIC DSC core delivers 100 MIPS with a fixed-point DSP engine supporting two 40-bit accumulators, while the peripheral ecosystem includes UART, SPI, I2C, and configurable logic modules. The 8 KB of SRAM supports control-loop state variables and communications buffers, and the 64 KB flash provides ample space for control firmware and a bootloader.
Typical applications include digital power supplies, brushless DC and PMSM motor drives, solar micro-inverters, LED drivers, and advanced sensing and control nodes. The integrated op-amps and fast ADCs reduce bill-of-material cost in current-sensing power stages, and the PWM resolution suits phase-shifted and synchronous converter topologies.
For design, place the VCAP bulk capacitor close to the core-regulator pin and keep the analog supply filtered from the digital rail to preserve ADC accuracy at full sample rate.

主な用途
DSPIC33CK64MP202-E/2N の用途: 6 件s: Digital Power Supplies, Brushless Motor Drives (BLDC/PMSM), Solar Micro-Inverters and Power Conversion, LED Drivers and Lighting Control, Advanced Sensing and Control Nodes, Industrial Automation and Robotics.
Digital Power Supplies
The DSPIC33CK64MP202-E/2N fits digitally controlled AC-DC and DC-DC converters where its 100 MHz core executes average-current-mode loops at switching frequencies well above 100 kHz. The 12-bit ADC with fast sampling captures inductor current at mid-PWM-cycle for peak- and average-mode control, while integrated op-amps condition shunt-resistor signals without external amplifiers, cutting BOM cost per channel. High-resolution PWM provides sub-nanosecond duty resolution, critical for phase-shifted full-bridge and LLC topologies where pulse-level accuracy limits efficiency. The dual-panel flash supports field firmware updates for remote power systems. Place the ADC sample trigger from the PWM peripheral, not software, to guarantee loop timing determinism, and budget CPU cycles so the control ISR completes before the next PWM period to avoid loop jitter that degrades transient response and audible-noise performance.
おすすめ
Brushless Motor Drives (BLDC/PMSM)
Field-oriented control of PMSM and BLDC motors demands fast, deterministic execution - the 100 MHz dsPIC33CK core runs FOC inner loops with single-cycle multiply-accumulate from its DSP engine. The DSPIC33CK64MP202's 12-bit ADC samples two phase currents synchronously with PWM center, its on-chip op-amps amplify low-value shunts directly, and the high-resolution PWM generates complementary outputs with precise dead-time insertion for the three-phase inverter. The -E extended temperature grade of this part tolerates +125C ambient near hot motor drive environments where standard industrial parts derate. Implement the current-loop ISR at the PWM frequency and the speed loop at 1 kHz; use the hardware dead-time registers rather than software delays so dead time stays constant across duty range, preventing shoot-through at light load and low duty cycles.
おすすめ
Solar Micro-Inverters and Power Conversion
Micro-inverter control requires simultaneous MPPT execution, grid-synchronization, and safety monitoring - the 64 KB dual-panel flash of the DSPIC33CK64MP202 holds MPPT algorithms, PLL grid-lock code, and a bootloader for field upgrades without halting power conversion. The 12-bit ADC's multiple scan channels track PV voltage/current and grid voltage concurrently, and the 100 MHz core sustains the DSP-heavy grid synchronization math at switching frequencies typical of interleaved boost stages. Extended -40C to +125C operation suits rooftop enclosures exposed to solar heating. Keep the analog front-end grounds star-routed to a single point at the IC, since switching-stage ground bounce of even tens of millivolts is measurable by a 12-bit ADC and corrupts MPPT decisions; use the integrated op-amps close to the shunts to preserve signal margin.
おすすめ
LED Drivers and Lighting Control
High-power LED drivers benefit from the DSPIC33CK64MP202's high-resolution PWM, which achieves dimming resolution beyond the flicker-perception threshold even at deep dim levels, where an 8-bit-equivalent PWM would produce visible steps. The 12-bit ADC monitors LED current through a shunt amplified by the on-chip op-amp, closing a constant-current loop at the 100 MHz core's control rate. The extended -E temperature grade suits enclosed luminaires where ambient near the driver electronics regularly exceeds 85C. Use the part's complementary PWM outputs for synchronous buck LED stages to improve efficiency over asynchronous topologies, and implement thermal foldback in firmware by scaling the current reference from a measured board-temperature channel - the ADC sample sequence keeps the temperature loop independent of the fast current loop without CPU contention.
おすすめ
Advanced Sensing and Control Nodes
Industrial sensing nodes use the DSPIC33CK64MP202 to acquire analog signals through its 12-bit ADC and integrated op-amps, apply DSP filtering (IIR/FIR) with the hardware MAC engine, and transmit results over UART, SPI, or I2C. The 8 KB SRAM buffers sample streams while the 100 MHz core keeps up with millisecond-scale control tasks. Functional Safety (FuSa) support documented by distributors makes the part appropriate for sensing paths feeding safety-related shutdown decisions, subject to the applicable safety development flow. Execute the digital filter in the main loop and communication in interrupt context so sensor latency stays bounded; oversample and average the ADC in hardware where the channel allows, since the 3.5 Msps-class conversion rate gives ample headroom to trade speed for effective noise-free resolution in slow physical measurements.
おすすめ
Industrial Automation and Robotics
Within automation equipment, the DSPIC33CK64MP202-E/2N serves as a dedicated real-time motion or power-stage controller subordinate to a system host. Its 100 MHz core closes current loops while communicating setpoints over UART or SPI to a supervisory controller; deterministic interrupt latency ensures repeatable torque response for robotic joint modules. The -40C to +125C extended rating tolerates cabinet-hot factory floors and enclosed drive electronics, and the FuSa support streamlines documentation for machinery integrators following safety-driven development processes. Offload encoder decoding to the peripheral set rather than software counting to keep ISR load low, and reserve the dual-panel flash for staged firmware rollout across a robot fleet - the alternate panel lets a verified image roll back automatically if a new control profile fails a power-on self-test sequence.

設計ノート
On the 28-UQFN 6x6 land pattern, the exposed thermal pad under the die is the primary ground path - connect it to a solid ground plane with a 3x3 or 4x4 via array. Place the VCAP (core regulator) capacitor within 2 mm of its pin with a short, wide trace; core-supply impedance is the most common source of erratic reset behavior on dsPIC33CK designs. Keep the analog supply pin filtered with an LC or ferrite bead from the digital rail to protect ADC accuracy at high sample rates.
Estimated: at 100 MHz core frequency, dsPIC33CK supply current is typically in the tens of milliamps per the family reference manual (exact figure depends on your operating frequency and peripheral load - consult the datasheet current-vs-frequency table). Size the local 3.3 V rail budget accordingly and add bulk capacitance near the IC for PWM-peripheral switching transients. At +125C ambient, derate the supply regulator's output current and verify its own thermal margin before finalizing the design.
Verify the temperature grade before substituting parts: the -E grade runs to +125C while the cheaper -I grade stops at +85C, and commercial-grade stops at +70C - a hidden substitution can pass bench tests and fail in the field. Additionally, dsPIC33CK peripheral pin select (PPS) means pin functions are software-assigned; re-compiling firmware from a different family member can silently remap UART/SPI pins. Always diff the configuration-word and PPS register settings when porting code between the alternatives listed on this page.
