PIC24EP64MC204-E/MV 概要
A motor-control MCU is a microcontroller integrated with analog feedback peripherals, timer/capture units, and deterministic PWMs intended to implement Field-Oriented Control (FOC), sinusoidal commutation, and PI current loops in a single chip. In the broader taxonomy, the PIC24EP64MC204 sits in the 16-bit MCU class, below 32-bit Cortex-M devices and above 8-bit PIC16/PIC18 controllers; it belongs to Microchip's dsPIC33/PIC24E family which combines MCU programmability with light DSP throughput for sensorless and sensored motor algorithms. The PIC24E architecture is designed to displace DSP+FPGA motor-control designs with a single deterministic core.
Key features include the MCPWM with up to 6 PWM outputs and 1.04 ns PWM resolution, dual 10-bit ADC modules with up to 1.1 Msps aggregate sampling, three on-chip op-amps for current sensing without external amplifiers, four analog comparators with DAC references, and a Peripheral Trigger Generator (PTG) that lets the CPU offload deterministic event sequences. It also integrates a Parallel Master Port (PMP) for graphics or external memory, multiple UART/SPI/I2C interfaces, and a Real-Time Clock Calendar (RTCC) for time-stamping.
Typical applications include field-oriented control (FOC) of 3-phase PMSM/BLDC motors in drones, e-bikes, appliances, and industrial drives, single-phase and three-phase PFC power conversion, solar micro-inverters, and digital uninterruptible power supplies. The integrated op-amps and comparators cut BOM cost by eliminating external analog front-ends.
When designing with the PIC24EP64MC204-E/MV, allocate a 4-layer PCB with a solid ground pour beneath the exposed pad to keep the -40 C to +125 C junction profile within safe limits. The UQFN-48 has a thermal pad that MUST be soldered to the PCB ground plane for both electrical and thermal performance. Use the MPLAB X IDE with the MPLAB XC16 compiler plus the Motor Control Library (MCLv2) for development.

主な用途
PIC24EP64MC204-E/MV の用途: 7 件s: Field-Oriented Control (FOC) of 3-Phase PMSM/BLDC Motors, Sensorless BLDC Motor Control with Back-EMF Detection, Single-Phase and Interleaved PFC Power Conversion, Solar Micro-Inverter and Small String Inverter Control, Industrial Variable Frequency Drive (VFD) Low-Power Stage, Appliance and White Goods Motor Control, Drone and E-Bike Motor Control.
Field-Oriented Control (FOC) of 3-Phase PMSM/BLDC Motors
The PIC24EP64MC204-E/MV is purpose-built for FOC motor control. Its 6-channel MCPWM provides complementary outputs with programmable dead-time to drive a 3-phase inverter bridge, the 3 on-chip op-amps condition shunt-resistor current signals without external amplifiers, and the 4 analog comparators implement hardware overcurrent protection. The 70 MIPS performance runs the FOC algorithm at 20 kHz+ loop rate with adequate headroom for space-vector modulation. Microchip's Motor Control Library (MCLv2) provides ready-compiled FOC firmware. Compared to a general-purpose MCU plus external op-amp/ comparator circuitry, this part eliminates 2-3 active components from the BOM.
おすすめ
Sensorless BLDC Motor Control with Back-EMF Detection
The PIC24EP64MC204-E/MV supports sensorless BLDC commutation by sampling back-EMF voltages through its 10-bit ADC and using on-chip comparators for zero-crossing detection. The Peripheral Trigger Generator (PTG) sequences ADC samples to back-EMF windows automatically. The 64 KB Flash architecture fits zero-crossing state machines plus speed PI control loops, and the 8 KB SRAM holds the lookup tables for trapezoidal commutation. The integrated analog chain removes the need for an external comparator IC typically required for sensorless commutation.
おすすめ
Single-Phase and Interleaved PFC Power Conversion
For digital PFC converters, the PIC24EP64MC204-E/MV runs CCM/DCM control loops at 50-100 kHz switching frequency using the MCPWM. The high-speed ADC samples the rectified mains voltage and inductor current, while the on-chip op-amps condition current-sense signals. The DSP engine accelerates RMS power calculations for THD optimization. The 3.3 V supply, 64 KB Flash and industrial -40 C to +125 C range cover PFC requirements across consumer and appliance product lines.
おすすめ
Solar Micro-Inverter and Small String Inverter Control
The PIC24EP64MC204-E/MV provides the control plane for sub-300 W micro-inverters. The MCPWM drives the full-bridge inverter stage, the ADC samples PV panel voltage/current and grid voltage, and the DSP engine runs MPPT plus grid-synchronization algorithms. The PTG synchronizes ADC sampling to PWM timing to eliminate switching noise in measurements. Compared to using a discrete DSP plus MCU architecture, this part saves PCB area and BOM cost while meeting small-form-factor micro-inverter requirements.
おすすめ
Industrial Variable Frequency Drive (VFD) Low-Power Stage
The PIC24EP64MC204-E/MV targets low-power industrial VFDs up to ~1 kW. It implements V/Hz or sensorless vector control algorithms, drives IGBT/MOSFET inverter stages through its MCPWM, and the QEI accepts encoder feedback for closed-loop vector control. The extended -40 to +125 C temperature range meets harsh industrial requirements, and the 64 KB Flash holds application-specific motor profiles plus protective firmware. The 48-UQFN package is small enough for compact IPM-based inverter designs.
おすすめ
Appliance and White Goods Motor Control
The PIC24EP64MC204-E/MV is widely used in washing machines, dishwashers, refrigerator compressors, and HVAC fans. The MCPWM drives the BLDC/PMSM motors common in modern appliances, the on-chip op-amps handle current sensing for torque control, and the integrated comparators implement safety overcurrent shutdown. The -40 to +125 C industrial temperature range suits appliance environments, and the small UQFN-48 package fits compact motor-control boards. The 70 MIPS performance runs advanced wash-cycle algorithms in real time.
おすすめ
Drone and E-Bike Motor Control
The PIC24EP64MC204-E/MV fits the high-RPM motor-control requirements of drones and e-bikes. The 70 MIPS PIC24E core runs fast FOC algorithms for brushless gimbal motors, propeller motors, and e-bike hub motors. The MCPWM provides the high-frequency PWM needed for low-inductance high-RPM motors, and the 3 on-chip op-amps handle current sensing on drone ESC boards. Compared to general-purpose MCUs, this integrated analog chain saves critical PCB space in space-constrained drone ESC designs.

設計ノート
The UQFN-48 (MV) package has a thermal pad on the bottom that serves as the primary heat-dissipation path. The thermal pad MUST be soldered to a PCB ground plane with adequate copper area (at least 1 square inch, ideally 2+ square inches of continuous copper) to keep junction temperature within the -40 to +125 C operating range. Without proper PCB thermal design, the part can thermally throttle or fail in motor-control applications where the MCU processes interrupts continuously. Use 4-layer PCB with ground pour beneath the package for best thermal performance.
Place the 0.1 uF + 10 uF decoupling capacitor pair as close as possible to each VDD/AVDD pin pair. The AVDD analog supply pin should be filtered with a ferrite bead or inductor to isolate from digital switching noise, since the ADC and comparators are sensitive to digital rail noise. Use a star-ground topology connecting the analog ground (AVSS) and digital ground (VSS) at a single point near the MCU for best ADC performance.
Route the high-current PWM traces to the gate driver with impedance matched to 50 ohms if traces exceed 25 mm, and keep the gate-driver loop area minimal to reduce parasitic inductance. Place the current-sense shunt resistors as close as possible to the low-side FET source pins, with the differential traces to the on-chip op-amps routed as a matched pair. For QEI encoder signals, keep traces short and use ground shielding to prevent PWM switching noise from coupling into encoder signals.
Estimated: programming NAND flash before Power-On Reset (POR) is released will lock the module. Avoid using the JTAG pins (TMS, TCK, TDU, TDI) as GPIO unless JTAG is disabled in configuration bits - leaving JTAG enabled by default causes accidental pin contention. Configure the PWM fault pins (FLT1, FLT2) before enabling the MCPWM module to prevent unexpected shutdowns. Do not exceed the absolute maximum 3.6 V on VDD or 4.0 V on any I/O pin.
The MCPWM outputs switch at high dV/dt rates that can inject common-mode noise into analog signals. Use differential routing for current-sense signals to the on-chip op-amps, and add a small RC filter (100 ohm + 1 nF) at the op-amp inputs to filter switching transients. The analog comparators can be used for hardware overcurrent protection with sub-microsecond response time, but the comparator output must be debounced in software if the input signal has noise.
