PIC24FJ32MC104-I/ML - 16-bit 16 MIPS 32KB Flash Motor MCU | Microchip
MPN: PIC24FJ32MC104-I/ML ✓ פעילPIC24FJ32MC104-I/ML סקירה
A PIC24F microcontroller is a 16-bit RISC MCU family from Microchip Technology that combines the legacy PIC16/PIC18 peripheral ecosystem with a 16-bit modified-Harvard core running up to 16 MIPS. Within the broader microcontroller taxonomy, PIC24F sits above PIC18 (8-bit) and below dsPIC33/PIC32 (32-bit), making it a mid-tier 16-bit solution for cost-sensitive, deterministic real-time control tasks. Motor-control variants like the PIC24FJ32MCxxx add dedicated PWM and analog front-end peripherals tuned for BLDC, PMSM, and stepper drive loops. The 44-QFN option keeps the BOM compact while exposing the full peripheral set.
Key features include 32 KB (11K x 24) self-programmable Flash, 2 KB SRAM, 5 MCPWM channels with dedicated fault inputs, 10-bit ADC up to 500 ksps, 2 analog comparators with programmable reference, CTMU for capacitive touch or time-of-flight, UART/SPI/I2C, and PPS for flexible pin mapping. The 16 MIPS core supports C and assembly development under MPLAB X IDE with the XC16 compiler. On-chip debug is provided through the standard 2-wire ICD interface.
Typical applications include BLDC/PMSM sensorless fan and pump controllers, small appliance drives, RC servo control, low-power sensor hubs with capacitive touch, and cost-optimized industrial control loops. The QFN-44 footprint is well suited for board-space-constrained designs where thermal dissipation is also acceptable.
When designing with the PIC24FJ32MC104-I/ML, place a 10 uF plus 0.1 uF decoupling pair near VDD, route the analog AVdd/AVss pair through a ferrite bead or filter, and follow Microchip's motor-control reference design layout for the MCPWM outputs to keep switching noise away from the CTMU/ADC paths.

יישומים טיפוסיים
PIC24FJ32MC104-I/ML מתאים עבור 7 יישוםs: BLDC Sensorless Fan and Pump Controller, Small Appliance Motor Drive (Mixer, Blender, Vacuum), Capacitive Touch User Interface, RC Servo and Drone ESC Controller, Industrial Sensor Hub with Motor Feedback, Medical Infusion Pump Stepper Controller, IoT Smart Home Fan with Wireless Connectivity.
BLDC Sensorless Fan and Pump Controller
The PIC24FJ32MC104-I/ML fits BLDC sensorless fan and pump control because its 5-channel MCPWM block and dual analog comparators provide back-EMF zero-cross detection without an external position sensor. With 32 KB Flash it accommodates trapezoidal or simple FOC firmware plus a UART command interface, and 2 KB SRAM is enough for state-machine commutation tables. At 16 MIPS the loop rate easily stays above 20 kHz for 4-pole fans and small centrifugal pumps. The 44-QFN 8x8 mm footprint keeps the controller area small enough to integrate on the motor PCB itself.
מומלץ
Small Appliance Motor Drive (Mixer, Blender, Vacuum)
For small-appliance drives the PIC24FJ32MC104-I/ML provides integrated fault-protected MCPWM outputs and a 10-bit ADC at 500 ksps for current sensing, eliminating most analog glue logic. The industrial -40C to +85C temperature grade covers kitchen and laundry environments. PPS allows the same firmware to map PWM to multiple board layouts, accelerating product variants. The 32 KB Flash is sized for sensorless FOC plus BLE or Wi-Fi co-processor command handling.
מומלץ
Capacitive Touch User Interface
The PIC24FJ32MC104-I/ML integrates the CTMU (Charge Time Measurement Unit) which enables reliable capacitive touch sensing on up to 16 channels without an external touch IC. The 16 MIPS core scans a 12-button keypad in under 2 ms with average firmware. PPS remaps CTMU inputs to spare GPIO when MCPWM channels consume the dedicated pins. 2 KB SRAM holds debounce, slider, and gesture state without taxing the Flash budget.
מומלץ
RC Servo and Drone ESC Controller
Hobby-grade RC servos and small drone ESCs benefit from the PIC24FJ32MC104-I/ML's deterministic 16 MIPS performance and 5 MCPWM channels with hardware fault shutdown. The 32 KB Flash fits DSHOT and standard PWM protocols plus on-the-fly throttle calibration. The 44-QFN small footprint suits 20-30 A ESC boards where PCB area is at a premium. Dual analog comparators provide BEMF sensing for sensorless trapezoidal commutation down to 1 kV bus voltage.
מומלץ
Industrial Sensor Hub with Motor Feedback
The PIC24FJ32MC104-I/ML serves as a sensor hub that combines analog sensor sampling with on-board motor trim control. The 10-bit ADC reads up to 13 analog channels, while MCPWM drives a small position-control motor. The CTMU adds capacitive level/proximity sensing. 2 KB SRAM is sufficient for Kalman-filter state vectors. The -40C to +85C industrial rating supports factory-floor deployment.
מומלץ
Medical Infusion Pump Stepper Controller
Stepper-controlled medical infusion pumps use the PIC24FJ32MC104-I/ML for precise microstepping drive and redundant safety monitoring. The MCPWM and dual comparators enable closed-loop stall detection without external position sensors. PPS allows the same firmware to drive bipolar or unipolar stepper topologies. The 32 KB Flash accommodates IEC 62304-style firmware plus a watchdog and self-test routine. Industrial temperature grade supports clinical and home-care environments.
מומלץ
IoT Smart Home Fan with Wireless Connectivity
Smart-home ceiling fans and exhaust fans pair the PIC24FJ32MC104-I/ML with an external Wi-Fi or BLE module to enable app and voice control. The MCU handles sensorless BLDC commutation while the wireless module manages connectivity. PPS lets designers assign UART/SPI pins to the wireless module without remapping motor-drive signals. 32 KB Flash is enough for the motor-control state machine and a small command parser, leaving room for OTA-bootloader stub.

הערות תכנון
Place a 10 uF bulk + 0.1 uF ceramic decoupling pair within 5 mm of the VDD pin and a separate pair near AVdd. According to the PIC24FJ32MC101/102/104 datasheet, AVdd should be filtered from Vdd through a ferrite bead or 10 ohm resistor to keep ADC and CTMU noise isolated from digital switching noise.
Route the MCPWM output traces as short, matched-length pairs to the gate driver inputs. Keep switching traces away from the CTMU/ADC analog inputs. Per Microchip motor-control reference designs, expose a low-impedance thermal pad under the 44-QFN to the inner ground plane with multiple stitching vias for thermal dissipation.
Do not exceed the maximum core clock of 32 MHz (16 MIPS). When using PPS, remember that analog functions have fixed pin assignments and cannot be remapped. Leave the ICD PGC/PGD pins (RB6/RB7) accessible for in-circuit debug headers during prototyping.
For back-EMF sensing, the analog comparators' reference ladder must be bypassed with a 100 nF capacitor. Route comparator inputs in parallel-trace fashion with a ground guard. Per Microchip AN1078, common-mode noise on BEMF inputs is the most common cause of sensorless start-up failure.
