DSPIC33FJ64MC804-E/ML 概要
A digital signal controller combines the computation throughput of a DSP engine with the peripheral set and ease of use of a microcontroller. Within the power-management hierarchy, the dsPIC33F family sits between general-purpose MCUs and standalone DSPs: it is a 16-bit processor core with integrated DSP multiply-accumulate instructions, making it a single-chip solution for control loops and signal processing.
Key features of this part include a 16-bit modified Harvard architecture running up to 40 MIPs, motor-control PWM and advanced analog peripherals, and pin compatibility with the PIC24HJ family, which eases migration between controller families. The 64 KB Flash supports in-circuit self-programming, and the 16 KB SRAM provides headroom for control algorithms and buffering.
The MC804 subfamily is specifically architected for precision motor control: dedicated motor-control PWM outputs, high-speed ADC sampling, and DSP instructions for field-oriented control (FOC) transforms. The advanced analog block integrates a fast ADC and comparators that offload the core in current-loop applications.
Typical applications include brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) drives, switch-mode power supplies and power factor correction, digital power metering, and industrial automation nodes where high-speed repetitive computation is required.
When designing with this device, decouple the 3.3 V rail locally at each VDD/VSS pair and follow the Microchip family reference manual for oscillator layout, since a stable 40 MIPS clock is central to control-loop timing.

主な用途
DSPIC33FJ64MC804-E/ML の用途: 6 件s: BLDC / PMSM Motor Control, Switch-Mode Power Supplies & Digital Power, Industrial Automation & Control Nodes, Power Metering & Energy Monitoring, Automotive-Adjacent & High-Temperature Embedded Control, Signal Processing & Sensor Fusion Nodes.
BLDC / PMSM Motor Control
The DSPIC33FJ64MC804-E/ML is purpose-built for precision motor control: its 40 MIPs DSP core executes field-oriented control (FOC) transform math fast enough for typical 10-20 kHz current loops, while the dedicated motor-control PWM block generates complementary or independent PWM outputs with dead-time insertion. The advanced analog front end with high-speed ADC sampling captures phase currents for closed-loop torque control. The 64 KB Flash holds the control firmware plus communication stacks, and 16 KB SRAM provides state storage. Used as the main controller between current-sense amplifiers and a three-phase gate driver, it replaces a separate MCU+DSP two-chip solution, cutting BOM cost and control-loop latency. The -40C to +125C E-grade rating suits sealed motor drives near heat sources.

Switch-Mode Power Supplies & Digital Power
In digital power supplies, PFC stages, and DC-DC converters, the DSPIC33FJ64MC804-E/ML acts as the digital compensator: its 40 MIPs core executes PID/2p2z compensation loops with DSP multiply-accumulate instructions, and the motor-control PWM block provides the precision duty-cycle resolution and phase-shift modes needed for LLC and phase-shifted full-bridge topologies. The advanced analog ADC samples output voltage and current synchronously with the PWM cycle, minimizing control delay. Running from a 3.3 V rail with the E-grade -40C to +125C rating, it tolerates hot power-supply enclosures. Compared with analog controllers, firmware-based control enables programmable soft-start, adaptive dead time, and in-field tuning without hardware changes.
おすすめ
Industrial Automation & Control Nodes
The dsPIC33F 16-bit family is, per Microchip, ideal for applications relying on high-speed, repetitive computations as well as control - exactly the profile of industrial automation nodes such as servo axes, pumps, conveyors, and actuator controllers. The DSPIC33FJ64MC804-E/ML delivers 40 MIPs for control-law execution while standard MCU peripherals handle serial links, encoders, and safety interlocks. Its 64 KB Flash supports field firmware updates over industrial buses, and the 44-QFN (8x8 mm) package fits compact distributed-control PCBs. The -40C to +125C rating covers unconditioned cabinets and machinery-mounted electronics. Designers often pair it with an isolated RS-485/CAN transceiver and a supervisor IC for robust 24 V industrial environments.
おすすめ
Power Metering & Energy Monitoring
Digital power metering requires simultaneous, phase-accurate sampling of voltage and current channels plus DSP-class math for RMS, power factor, and harmonic analysis - the DSPIC33FJ64MC804-E/ML covers both requirements with its 40 MIPs core, advanced analog ADC, and 16 KB SRAM for waveform buffers. The 3 V to 3.6 V low-power supply suits metering front ends, and the extended -40C to +125C temperature range meets outdoor meter enclosure requirements. Firmware flexibility allows a single hardware platform to serve multiple metering standards and tariffs via software updates written into the 64 KB Flash. Microchip literature identifies industrial power metering among the dsPIC33F MC-family target applications, and the 44-QFN package enables compact meter PCBs.
おすすめ
Automotive-Adjacent & High-Temperature Embedded Control
With the E suffix denoting -40C to +125C operation, the DSPIC33FJ64MC804-E/ML addresses under-hood-adjacent and high-temperature industrial locations - pump controllers, cooling-fan drivers, actuators, and solenoid control - where consumer-grade parts cannot survive. The 40 MIPs core runs deterministic control loops while motor-control PWM drives solenoids and small motors directly through external gate drivers. The 3 V to 3.6 V supply allows sharing a regulated rail with other automotive-style 3.3 V electronics. Note this part is not AEC-Q100 qualified by default; for formal automotive programs, consult Microchip for qualified variants. For environments guaranteed below +85C, the cheaper I-grade sibling offers identical function.
おすすめ
Signal Processing & Sensor Fusion Nodes
The dsPIC33F architecture combines MCU control with DSP engine speed, making the DSPIC33FJ64MC804-E/ML effective for embedded signal-processing tasks: digital filtering (FIR/IIR), FFT-based vibration analysis, and sensor fusion where multiply-accumulate throughput at 40 MIPs outperforms typical general-purpose MCUs. The advanced analog ADC feeds processing pipelines directly, and 16 KB SRAM holds filter states and window buffers. The 44-QFN (8x8 mm) 35-I/O footprint supports dense multi-sensor boards. Because the family is pin-compatible with PIC24HJ devices per Microchip, designers can start with the MC804 and re-target the same PCB footprint to a GP or higher-memory sibling if the processing profile changes - reducing redesign risk in evolving products.

設計ノート
Run the DSPIC33FJ64MC804-E/ML from a clean 3.3 V LDO output within its 3 V to 3.6 V specification. Place a 0.1 uF ceramic capacitor at every VDD/VSS pin pair plus one bulk 10 uF capacitor near the package. On motor-control boards where PWM switching injects noise into the ground plane, segregate the analog ground under the advanced analog pins and return it at a single point to the power ground - a noisy ground is the most common cause of ADC jitter in dsPIC33F motor-control designs.
The 44-QFN (8x8 mm) package has a center thermal/electrical pad - connect it to the ground plane with an array of thermal vias (typically 4x4) to improve heat spreading and grounding integrity, since the QFN pad is often the primary VSS connection. Keep the oscillator traces short and guarded; a stable clock is essential at 40 MIPs. Route PWM outputs away from the ADC input traces to prevent digital switching coupling into current-sense samples used by the FOC control loop.
Match the suffix grade to your environment: the E part is rated to +125C but costs more and stocks less deeply than the I-grade -40C to +85C variant; do not substitute I-grade into designs that can exceed +85C. Also, cross-family substitution to PIC24HJ or GP804 is pin-compatible but NOT firmware-compatible: motor-control PWM registers and analog configuration differ, so budget requalification time. Configure MCLR and configuration words (oscillator, watchdog, code protection) before first programming - a mis-set oscillator config is the leading cause of 'dead' new boards.
