DSPIC33CK32MP102-E/SS 概要
A digital signal controller combines the computational throughput of a digital signal processor with the peripheral integration and control-oriented architecture of a microcontroller, sitting between a general-purpose MCU and a dedicated DSP in the embedded processor hierarchy. The dsPIC33C family executes one instruction per cycle with DSP multiply-accumulate (MAC) instructions, rounding, and saturation support, making it a common choice where deterministic control loops run at high frequency.
Key features of this device include the 100 MHz single-core CPU with integrated DSP engine, high-speed 12-bit ADCs, on-chip operational amplifiers, analog comparators, and a high-resolution PWM module - the peripheral mix Mouser summarizes as 100MHz, 32K Flash, 8K RAM, OpAmps, 12bit ADCs, PWM. DigiKey additionally classifies the part as a Functional Safety (FuSa) capable dsPIC33CK device.
The integrated op amps allow current-sense amplification for phase-current feedback without external amplifiers, reducing BOM cost and board area in power conversion designs. The high-resolution PWM supports industry-leading edge placement resolution, which is critical for peak-current-mode and phase-shifted converter topologies.
Typical applications include digital power supplies (the dsPIC33CK32MP102 is used in the EPC9143 48 V-to-12 V DC/DC brick reference design with EPC eGaN FETs), brushless DC and PMSM motor control, and advanced sensing and control systems. The AEC-Q100 qualification reported by distributors makes it suitable for automotive subsystems as well.
Design consideration: the dsPIC33CK core requires a VCAP capacitor on the internal regulator output for stable operation, and the 3.3 V supply should be decoupled per the manufacturer datasheet guidance.

主な用途
DSPIC33CK32MP102-E/SS の用途: 6 件s: Digital Power Conversion, Brushless DC and PMSM Motor Control, Advanced Sensing and Control Systems, Automotive Electronic Subsystems, LED Drivers and Lighting Power, Embedded Power Module Reference Designs.
Digital Power Conversion
The DSPIC33CK32MP102-E/SS is a proven controller for switched-mode power supplies and DC/DC brick converters. Its 100 MHz single-cycle core executes voltage- and current-loop compensation in well under one switching period, while the high-resolution PWM provides fine edge placement needed for phase-shifted full-bridge and LLC topologies. The 12-bit high-speed ADC samples feedback with low latency, and the integrated op amps amplify shunt current signals without external amplification. Microchip's EPC9143 48 V-to-12 V reference design with EPC eGaN FETs demonstrates this device controlling a 1/16th brick module, giving engineers a validated starting point. The AEC-Q100 E-temp grade also supports automotive onboard charger and auxiliary power stages where ambient temperatures reach 125C.
おすすめ
Brushless DC and PMSM Motor Control
For sensorless FOC and trapezoidal BLDC drives, the DSPIC33CK32MP102-E/SS combines the DSP throughput needed for field-oriented control with the exact analog front end the task requires. The on-chip operational amplifiers condition low-side shunt phase currents directly, the 12-bit ADC triggers synchronously with the PWM, and comparator outputs can support fast overcurrent shutdown paths. The 100 MHz core closes current loops at switching frequency with headroom for observers such as sliding-mode or back-EMF estimators. Its 28-pin SSOP footprint keeps drive boards compact, and the -40C to +125C E-temp rating suits under-hood and industrial drives. Microchip motor-control development boards (MCLV/MCHV families) support dsPIC33CK evaluation for rapid firmware bring-up.
おすすめ
Advanced Sensing and Control Systems
The DSPIC33CK32MP102-E/SS fits sensing nodes and closed-loop controllers that mix analog acquisition with real-time signal processing. The 12-bit high-speed ADC captures fast transients, the on-chip op amps buffer sensor outputs, and the DSP MAC instructions execute digital filters (IIR/FIR) cycle-deterministically - a capability general-purpose MCUs in the same price class often lack. The 3.3 V supply, compact SSOP-28 footprint, and FuSa-capable classification per DigiKey make it practical for functional-safety-adjacent industrial control. With 32 KB Flash and 8 KB RAM it hosts protocol stacks and filtering code comfortably for single-function sensing products, and the E-temp grade allows deployment in outdoor or enclosed equipment reaching 125C ambient.
おすすめ
Automotive Electronic Subsystems
Distributor data classifies the DSPIC33CK32MP102-E/SS as Automotive, AEC-Q100 qualified, within the dsPIC33CK series. Combined with the -40C to +125C E-temp operating range and Functional Safety (FuSa) capability flagged by DigiKey, the device addresses automotive control functions such as DC/DC auxiliary converters, pump and fan motor control, and actuator position control. Designers benefit from deterministic 100 MIPS DSP performance for loop control plus integrated analog (12-bit ADC, op amps, comparators) that reduces external component count on constrained PCB areas. For production programs, confirm the exact safety integrity level support with Microchip, and consider the same-footprint I-temp part for non-temperature-critical cost-optimized variants of the same board.
おすすめ
LED Drivers and Lighting Power
Digitally controlled LED drivers use the DSPIC33CK32MP102-E/SS for constant-current regulation, dimming, and power-factor-corrected front ends. The high-resolution PWM drives switching stages and supports precise dimming resolution, while the 12-bit ADC closes the current loop with low latency and the on-chip op amps sense shunt currents without added amplifiers. The 100 MHz core manages PFR compensation and communication (UART/SMBus-style interfaces) concurrently. The 28-pin SSOP package suits compact driver boards used in industrial and architectural lighting, and the -40C to +125C E-temp rating accommodates hot luminaire environments near the LED source. Firmware upgrade paths within the pin-compatible dsPIC33CK 28-pin family protect the design across power levels.
おすすめ
Embedded Power Module Reference Designs
The dsPIC33CK32MP102 serves as the control element in reference designs that pair wide-bandgap semiconductors with digital control - most notably the EPC9143 1/16th brick power module, developed by Microchip with Efficient Power Conversion, which controls EPC2053 eGaN FETs in a 48 V-to-12 V DC/DC application. This validates the device in high-frequency GaN-based converter environments where loop bandwidth, ADC trigger latency, and PWM resolution determine efficiency. Engineers designing power modules with GaN or SiC stages can adopt the same controller with proven firmware architecture, using the SSOP-28 footprint for controller daughter cards. The E-temp grade supports thermally aggressive module environments typical of dense power conversion.

設計ノート
Supply the dsPIC33CK core from a clean 3.3 V rail and fit the VCAP capacitor required by the internal core regulator per the manufacturer datasheet recommendations - omitting or mis-sizing this capacitor is the most common cause of erratic reset or core brownout behavior on dsPIC33C designs. Place the VCAP capacitor physically adjacent to pin 11 with a short, direct return path to VSS. Decouple each VDD pin (pins 7 and 16 in the 28-SSOP) with local ceramic capacitance, and route analog grounds for the ADC and op amps to a quiet ground point per the datasheet PCB layout guidance.
For digital power layouts, keep the PWM outputs (remappable RP pins) on short traces to gate drivers, and route the op-amp current-sense inputs as Kelvin connections directly to the shunt resistor sense nodes to preserve the accuracy the integrated amplifiers enable. Trigger the 12-bit ADC from the PWM module rather than software loops so that sampling instant is deterministic relative to the switching edge. Use the PGD/PGC programming pin pairs (they double as RP I/O in this pinout) with series resistors if they drive external circuitry, so in-circuit programming is not impeded.
Do not confuse the DS (extended, -40C to +125C) suffix parts with I-grade parts in production BOMs: only the -E/SS grade is qualified across the full automotive ambient range even though the die is identical. Also verify package-footprint compatibility when cross-referencing within the dsPIC33CK family - the MP102 exists in 28-pin SPDIP (/2N and /SP variants), SOIC, and SSOP packages with the same die but different mechanical footprints; only the /SS variants are drop-in on a 28-SSOP land pattern.
