DSPIC33AK64MC105-E/M7 Overview
A digital signal controller combines the processing capabilities of a digital signal processor (DSP) with the peripheral integration and ease of use of a microcontroller (MCU). This hybrid architecture enables real-time signal processing tasks such as filtering, FFT, and field-oriented motor control, while also managing system-level functions like communication and I/O control in industrial automation and digital power systems.
Key features include the 200MHz operating frequency, 32/64-bit FPU for accelerated floating-point math, MC-PWM peripherals for motor control, and multiple 12-bit ADC channels sampling at up to 40MSPS. The integrated op amps and comparators reduce external component count, lowering BOM cost and board area.
From a technical perspective, the dsPIC33A core is designed for deterministic real-time execution with hardware multiply-accumulate (MAC) units, barrel shifter, and DMA controllers. The FPU supports single and double precision operations, enabling complex control algorithms such as FOC to run efficiently at high loop rates.
Typical applications include field-oriented control of BLDC and PMSM motors, digital power conversion (PFC, LLC converters), industrial automation, and advanced sensing systems requiring fast, precise analog interfacing.
When designing with this device, ensure proper decoupling of supply pins and a solid ground plane; solder the exposed pad of the VQFN package to the PCB for thermal dissipation. Prices referenced are as of 2026-08-29.

Typical Applications
DSPIC33AK64MC105-E/M7 is suitable for 6 applications: BLDC/PMSM Motor Control (FOC), Digital Power Conversion, Industrial Automation and Sensing, Automotive Embedded Control, Renewable Energy Inverters, Audio Signal Processing.
BLDC/PMSM Motor Control (FOC)
The DSPIC33AK64MC105-E/M7 excels in field-oriented control of brushless DC and permanent-magnet synchronous motors. Its MC-PWM peripheral generates complementary PWM with programmable dead-time, while 40MSPS 12-bit ADCs sample phase currents synchronously with PWM for minimal control-loop latency. The 200MHz core with 32/64-bit FPU executes Park/Clarke transforms and PI current loops at high rates without fixed-point scaling effort. Integrated op amps amplify shunt-current signals, reducing external component count in servo drives, e-mobility traction, and industrial robotics.
Recommended
Digital Power Conversion
For PFC stages, LLC converters, and DC-DC digital power, the DSPIC33AK64MC105-E/M7 provides deterministic 200MHz loop execution and high-speed analog. The 40MSPS 12-bit ADCs capture fast voltage/current transients, on-chip comparators support cycle-by-cycle overcurrent protection without CPU intervention, and the FPU accelerates nonlinear control laws. Integrated 100MHz op amps condition feedback signals, enabling compact AC-DC and telecom power supplies with firmware-configurable control and protection.
Recommended
Industrial Automation and Sensing
The extended -40C to +125C temperature rating and rich analog integration suit industrial automation nodes, sensor fusion, and condition-monitoring systems. The 200MHz FPU core runs FFT and digital filtering on vibration or current signatures in real time, while 16KB SRAM buffers sampled data via DMA. High-bandwidth op amps and comparators directly interface with sensors, and the compact 48-VQFN (6x6) package fits dense DIN-rail and embedded IO modules operating in harsh factory environments.
Recommended
Automotive Embedded Control
With the -E extended temperature grade (-40C to +125C), the dsPIC33A supports automotive-adjacent applications such as pump control, HVAC blowers, and auxiliary motor drives. The MC-PWM and fast ADCs handle inverter control, while the FPU offloads math-heavy diagnostics. Note: verify AEC-Q100 qualification status with Microchip for formal automotive programs; this device targets harsh-environment industrial and transportation applications where its analog integration and deterministic control reduce system cost.
Recommended
Renewable Energy Inverters
Solar microinverters, MPPT converters, and battery storage power stages benefit from the DSPIC33AK64MC105-E/M7's combination of DSP throughput and analog integration. The 40MSPS ADCs sample panel and bus voltages for maximum-power-point tracking, the FPU accelerates MPPT and grid-synchronization algorithms (SOGI PLL), and MC-PWM drives the power stage with precise dead-time. On-chip comparators implement hardware overcurrent shutdown, protecting SiC/GaN stages during grid faults.
Recommended
Audio Signal Processing
The 200MHz dsPIC33A core with 32/64-bit FPU executes real-time audio filtering, active crossover, and effects algorithms efficiently. DSP heritage means hardware MAC units and DMA-based sample streaming sustain multi-channel processing at low latency. While the integrated analog targets control rather than hi-fi audio, the device suits powered-speaker control combining DSP, protection, and motor/fan control in a single chip, and pairs naturally with dedicated audio codecs over SPI/I2C.

Key Differentiators
- 32/64-bit double-precision FPU (vs DSPIC33CK64MC105-E/M7)
- 40MSPS ADC sampling (vs DSPIC33CK64MC105-E/M7)
- Extended -40C to +125C operation (vs DSPIC33AK64MC105-I/M7)
Design Notes
Solder the exposed pad (EP) of the 48-VQFN (6x6) package to a solid ground plane with an array of thermal vias. At 200MHz operation, the EP is both the primary heat-removal path and the low-inductance ground return; skipping the EP solder joint is a leading cause of erratic ADC results and thermal shutdown in dsPIC33A designs.
Decouple each VDD pin with 100nF ceramic capacitors placed within 2mm of the pin, plus bulk 10uF per supply domain. The VDDCORE regulator output requires its specified capacitor per the Microchip datasheet - do not load it externally. At 40MSPS ADC sampling, keep the analog supply clean; consider an LC filter or dedicated LDO for AVDD in precision motor control designs.
The dsPIC33A core at 200MHz is fast enough that PWM dead-time and ADC sampling triggers must be hardware-synchronized via the peripheral trigger system rather than software polling - software latency at this clock rate can still miss PWM-cycle boundaries. Use the MC-PWM trigger to start ADC conversions for deterministic current-loop timing, per Microchip motor-control application notes.
Compliance Information
RoHS compliance per distributor listings; other compliance statuses require verification against Microchip product documentation.
