PIC24EP128MC202-H/MM 概要
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (RAM), and programmable peripherals. The PIC24E family uses a 16-bit modified Harvard architecture, meaning the program and data buses are separate, enabling simultaneous instruction fetch and data access for higher throughput. Within the broader hierarchy, the PIC24EP sits between 8-bit PIC18 devices and 32-bit PIC32 parts, optimized for DSP-like workloads such as field-oriented control (FOC) loops while remaining easy to program in C.
Key features include AEC-Q100 automotive qualification, an extended operating temperature range of -40C to +150C (H grade), and integrated op-amps that eliminate external analog conditioning stages for current sensing. A built-in 32-bit CRC engine, multiple communication interfaces (UART, SPI, I2C, ECAN), and 5 PWM modules (3 complementary pairs) support BLDC, PMSM, and stepper motor drive topologies with minimum external components.
Typical applications include automotive HVAC blowers, electric vehicle auxiliary pumps, industrial servo drives, drone ESCs, and consumer appliances such as washing-machine direct-drive motors. The combination of small footprint, automotive-grade qualification, and integrated analog makes the PIC24EP128MC202-H/MM especially suited for space-constrained, reliability-critical motor nodes.

主な用途
PIC24EP128MC202-H/MM の用途: 6 件s: BLDC Motor Control, Automotive HVAC Blower, Drone Electronic Speed Controller (ESC), Industrial Servo Drive, Washing Machine Direct-Drive, Electric Vehicle Auxiliary Pump.
BLDC Motor Control
The PIC24EP128MC202-H/MM's 1 ns PWM edge resolution and 60 MIPS throughput make it ideal for sensorless BLDC motor control using zero-cross detection and back-EMF sensing. The integrated three on-chip op-amps are commonly used for current-sense amplification on each phase leg, eliminating external analog stages. The 12-bit ADC running at 1.1 Msps samples the BEMF voltage at the PWM off-time with sub-microsecond latency, enabling 20 kHz FOC loops with comfortable CPU margin. AEC-Q100 qualification plus -40C to +150C operating range support automotive under-hood environments.
おすすめ
Automotive HVAC Blower
In an automotive HVAC blower controller, the PIC24EP128MC202-H/MM drives a 12V/24V BLDC fan using FOC with torque ripple compensation. Its AEC-Q100 qualification and 150C junction temperature rating allow direct under-dash mounting without derating. The on-chip comparators trip overcurrent protection in hardware within one PWM cycle (about 50 us at 20 kHz), bypassing firmware latency and protecting the FET stage. The 16 KB SRAM is sufficient to host both the speed-control PID loop and a UART-based diagnostic stack.
おすすめ
Drone Electronic Speed Controller (ESC)
Drone ESC designs use the PIC24EP128MC202-H/MM to drive 4 fast bidirectional DC or sensorless BLDC motors via DShot or PWM throttle protocols. The 60 MIPS core runs the FOC loop in about 12 us, leaving time for telemetry encoding and commutation timing. The exposed-pad 6x6 mm QFN keeps the ESC small enough to fit in 20x20 mm stack form factors, while -40C to +150C tolerates overheated operating conditions during aggressive flight maneuvers.
おすすめ
Industrial Servo Drive
For industrial servo drives and stepper controllers, the PIC24EP128MC202-H/MM provides closed-loop current and velocity control with deterministic PWM timing. The ECAN peripheral integrates seamlessly into CANopen or EtherCAT-slave stacks for multi-axis machine control. Hardware comparators limit current without firmware delay, while the on-chip op-amps read motor phase currents with low offset drift. Industrial-grade temperature range supports cabinet-internal or chassis-mounted installations.
おすすめ
Washing Machine Direct-Drive
Direct-drive washing machine motors require high-torque, low-speed FOC at high current, which the PIC24EP128MC202-H/MM supports via integrated op-amps for current sensing and 1 ns PWM for silent switching. The H-grade temperature rating is critical for enclosed appliance enclosures where ambient temperature reaches 85-95C. AEC-Q100 qualification, while not strictly required for consumer appliances, gives an additional reliability margin for white-goods manufacturers with long-life warranty requirements.
おすすめ
Electric Vehicle Auxiliary Pump
EV coolant pumps and oil pumps use the PIC24EP128MC202-H/MM as a compact motor-control node that communicates over CAN-FD with the vehicle ECU. The AEC-Q100 qualification and 150C operating range satisfy automotive OEMs' thermal derating requirements for under-hood placement. The on-chip CRC engine validates firmware integrity at startup, while the ECAN peripheral ensures robust communication on the noisy automotive bus. The 28-QFN-S package with exposed pad enables tiny pump-control PCBs under 25x25 mm.

設計ノート
Estimated: the 28-QFN-S 6x6 package has a theta_JA of approximately 32 C/W on a JEDEC 4-layer board (per Microchip datasheet package thermal data). At continuous full-load operation (60 MIPS with all peripherals active), self-heating is modest (under 1 W), but in motor-drive nodes where the MCU sits next to power FETs, thermal coupling dominates. Always solder the exposed pad to a continuous copper pour of at least 25x25 mm connected to VSS for best thermal dissipation, and keep high-current traces away from the package to minimize conducted heating.
Place the 8 MHz or 10 MHz primary oscillator crystal within 5 mm of OSCI/OSCO pins, with a continuous ground plane underneath to minimize EMI. Keep ADC analog traces short and away from PWM switching nets; use a guard ring around sensitive analog inputs to prevent switching noise coupling into current-sense measurements. Decouple VDD with a 100 nF ceramic capacitor placed within 2 mm of the supply pin, plus a 10 uF bulk capacitor on the same rail.
Do not exceed 3.6 V on VDD - the PIC24E core is not 5 V tolerant and will be permanently damaged. Verify the ECAN peripheral bit-timing configuration matches the bus baud rate and oscillator accuracy; incorrect settings yield CAN error-passive nodes. When migrating firmware between PIC24EP128 and PIC24EP256/512 variants, check that interrupt vectors and PMPS (PWM) shadow-register maps align - minor peripheral register differences exist between MC202 and MC502 silicon revisions.
When driving external gate drivers, the PWM output slew rate can couple into the MCU supply and reset internal op-amps. Place a ferrite bead or small resistor (10-33 ohm) in series with each PWM output to dampen switching transients. Use 100 nF decoupling at every supply pin, and route PWM return paths directly above their high-side/low-side traces to minimize loop inductance. For long PWM traces (>50 mm), add a buffer or gate-driver IC near the MCU to prevent ringing.
