PIC24FJ32MC104-E/TL 개요
A 16-bit microcontroller (MCU) is a single-chip processor that combines a 16-bit CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and a rich set of on-chip peripherals such as timers, ADCs, communication interfaces, and PWM channels. The PIC24F family sits within Microchip's broader taxonomy of PIC microcontroller -> 16-bit MCU -> motor-control MCU -> power-conversion and motion-control subsystem, and is widely used in appliances, fans, pumps, small drones, and consumer-embedded systems.
Key features include 16 MIPS performance at 32 MHz, 32KB Flash (11K x 24 words), 2KB SRAM, an integrated MCPWM with dedicated fault inputs, multiple 16-bit timers, a 10-bit A/D converter, and CTMU support for capacitive touch and current measurement. PPS allows most digital peripherals to be remapped to a wide range of I/O pins, simplifying PCB routing in compact motor-drive layouts. The CTMU enables time-based current sensing and touch sensing without external analog front-ends.
Architecturally, the PIC24FJ32MC104-E/TL uses a modified Harvard architecture with a 16-bit data path, hardware multiplier, and deterministic interrupt latency, which is essential for closed-loop field-oriented control (FOC) and trapezoidal commutation. The MCPWM block includes independent duty-cycle and period registers plus a dedicated PWM fault input that can shut down outputs within one PWM cycle when an overcurrent event is detected by an external comparator.
Typical applications include BLDC and PMSM motor control, sensorless fan and pump drivers, small appliance motor boards (mixers, blenders, hair tools), RC servo and drone ESC prototypes, and general-purpose low-pin-count industrial control. The wide operating voltage range and on-chip CTMU also enable capacitive user-interface buttons alongside the motor drive.
When designing with this device, place bypass capacitors (100 nF ceramic plus 4.7 uF or 10 uF bulk) within 5 mm of every VDD/VSS pair and ensure the exposed thermal pad is soldered to a continuous ground plane for thermal dissipation. Use the dedicated PWM fault pin to gate the MCPWM outputs whenever a hardware overcurrent trip occurs, never rely solely on firmware to disable the inverter.

일반적인 애플리케이션
PIC24FJ32MC104-E/TL 적합 용도: 6 애플리케이션s: BLDC / PMSM Motor Control, Sensorless Fan and Pump Motor Drivers, Small Appliance Motor Boards (Mixers, Blenders, Hair Tools), RC Servo and Drone ESC Prototypes, Industrial Low-Voltage Motor Drivers, Capacitive Touch User Interface with Motor Drive.
BLDC / PMSM Motor Control
The PIC24FJ32MC104-E/TL is purpose-built for 3-phase brushless DC and permanent-magnet synchronous motor control, integrating the Motor Control PWM (MCPWM) block with a dedicated hardware fault input that can shut down all PWM outputs within one PWM cycle on overcurrent events. Its 16 MIPS core running at 32 MHz is sufficient to execute field-oriented control (FOC) loops at 20 kHz PWM with ADC-triggered current sampling, while CTMU provides time-based current measurement for sensorless back-EMF zero-crossing or shunt-based FOC. The 44-pin VTLA package exposes enough I/O for three-phase complementary PWM, three current-sense ADCs, Hall sensors, encoder inputs, and UART/CAN to a host controller. Use the dedicated PWM fault pin tied to the gate-driver desaturation output to guarantee hardware-level inverter protection.

Sensorless Fan and Pump Motor Drivers
Compact consumer fans, CPU coolers, water pumps, and small appliance pumps benefit from the PIC24FJ32MC104-E/TL's CTMU and PPS peripherals. The CTMU enables accurate back-EMF zero-crossing detection for sensorless trapezoidal commutation, while PPS lets designers remap PWM and ADC channels to any available I/O pin for cleaner PCB routing. The 32 KB Flash is ample for sensorless start-up routines with BEMF filtering and speed PI control, and the -E extended temperature grade (-40 C to +125 C) tolerates the enclosed thermal environment of pump and fan housings. A typical design runs sensorless BEMF at 1-2 kHz PWM with current-limited soft-start.

Small Appliance Motor Boards (Mixers, Blenders, Hair Tools)
Household appliances such as hand mixers, blenders, and hair dryers use universal or BLDC motors controlled by a low-pin-count MCU with integrated PWM and protection. The PIC24FJ32MC104-E/TL's Motor Control PWM with hardware fault input provides reliable overcurrent protection required by safety standards for these products. Its 32 KB Flash stores user-interface state, motor speed profiles, and fault diagnostics, while CTMU supports capacitive touch buttons for sealed enclosures. Operating from 3.0 V to 3.6 V, the device easily interfaces to 3.3 V gate drivers and digital isolators in mains-powered appliance designs.

RC Servo and Drone ESC Prototypes
Electronic speed controllers (ESCs) for hobby drones and RC servos require fast PWM updates with hardware fault shutdown to protect FETs from shoot-through. The PIC24FJ32MC104-E/TL's 32 MHz / 16 MIPS core drives 8 kHz to 24 kHz FOC loops with adequate headroom, and its 44-pin VTLA footprint exposes UART for throttle command reception plus DShot or OneShot protocol decoding. The CTMU supports fast current-sampling for inner torque loops. The exposed thermal pad on VTLA helps dissipate the controller's heat when driving high-current drone motors.

Industrial Low-Voltage Motor Drivers
Industrial low-voltage drives for conveyors, automated valves, and small actuators benefit from the PIC24FJ32MC104-E/TL's extended -40 C to +125 C temperature range and integrated motor-control peripherals. The 32 KB Flash enables Modbus RTU or CANopen protocol stacks for industrial networking, while the CTMU and ADC support 4-20 mA analog feedback loops. The dedicated PWM fault pin can be tied to hardware overcurrent comparators for failsafe shutdown, essential in industrial safety systems. PPS allows UART, SPI, and I2C peripherals to be assigned to any available pin, simplifying layout in dense industrial enclosures.

Capacitive Touch User Interface with Motor Drive
Combining motor control with capacitive touch buttons in a single chip simplifies appliance designs, and the PIC24FJ32MC104-E/TL's CTMU peripheral enables direct touch sensing without external analog front-ends. The CTMU charges a sense line with known current and measures discharge time via timer capture, detecting finger proximity reliably through up to 5 mm of plastic or glass. Combined with the MCPWM block, a single MCU drives a motor and reads 4-8 touch pads simultaneously, eliminating separate touch-IC cost. PPS lets designers place touch electrodes on any unused pin.

설계 노트
Place a 100 nF ceramic bypass capacitor within 5 mm of every VDD/VSS pair on the PIC24FJ32MC104-E/TL, plus a single 4.7 uF to 10 uF bulk capacitor on the main 3.3 V rail. The VTLA package's exposed thermal pad is also the main ground return, so it MUST be soldered to a continuous ground plane stitched with multiple vias to the bottom layer. Inadequate decoupling causes MCPWM jitter and ADC noise that directly degrades motor-control loop stability.
Route the three-phase PWM outputs (PWM1H/L, PWM2H/L, PWM3H/L) as short matched-length traces to the gate driver, with a ground return path on an adjacent layer to minimize parasitic inductance that causes MOSFET ringing. Keep analog current-sense traces away from PWM switching traces, and use Kelvin connections at the shunt resistor sense points to avoid ground-loop errors. Place the ICSP programming pins (TMS, TCK, TDI, TDO) on a 0.1 inch header footprint for in-circuit debugging.
Do NOT skip the dedicated PWM fault pin (FLTA) connection to the gate-driver desaturation output - firmware-only overcurrent protection is too slow to prevent MOSFET shoot-through damage. The -E temperature suffix denotes -40 C to +125 C; the -I suffix is only -40 C to +85 C. Verify that the chosen suffix matches your application's thermal environment. PPS remapping requires unlocking the IOLOCK bit, so always include the unlock sequence in your initialization code.
For FOC motor control on the PIC24FJ32MC104-E/TL, sample phase currents in the middle of the PWM low-side ON interval using the MCPWM's special-event trigger to synchronize ADC sampling. This avoids switching noise from the FETs and produces clean current measurements for the Clarke/Park transforms. Add an RC anti-aliasing filter (typically 1 kohm and 470 pF) at each current-sense amplifier output before the ADC pin to suppress wideband noise.
