PIC24FJ32MC101-E/P - 16-Bit 32MHz Motor MCU | Microchip
部品番号: PIC24FJ32MC101-E/P ✓ 生産中PIC24FJ32MC101-E/P 概要
A PIC24 microcontroller is a programmable semiconductor combining a CPU core, memory, timers, communication peripherals, and analog functions on one integrated circuit. The PIC24 family uses a 16-bit modified Harvard architecture with an enhanced instruction set and addressing modes. This places the device in the hierarchy of embedded microcontroller, 16-bit RISC controller, embedded processor, and semiconductor, making it suitable for control systems that need more computation than an 8-bit MCU without the complexity of a higher-power application processor.
The PIC24FJ32MC101-E/P includes dedicated motor-control resources such as motor-control PWM modules, CTMU, and peripheral pin selection. Its 16 MIPS processing capability gives motor algorithms, communication routines, and supervisory logic more throughput than typical 8-bit designs. The 10-bit ADC supports analog feedback from current, position, speed, and temperature sensing networks, while I2C, SPI, and UART interfaces enable connection to sensors, drivers, debug equipment, and human-interface modules.
The 32 KB Flash memory provides 11K × 24 words of program storage, while 2 KB of SRAM supports working variables, control state, and communication buffers. Fifteen I/O pins offer access to digital control signals in a 20-pin PDIP package measuring 0.300 inches wide with a 7.62 mm row spacing. The device supports an industrial temperature range of -40 °C to +125 °C and is identified as an AEC-Q100 automotive-grade option.
Typical applications include single- or two-phase brushed motor controllers, low-power pump and fan controllers, compact power tools, appliance drive systems, automotive accessories, and industrial actuator modules. The combination of dedicated PWM, CTMU, and peripheral pin selection permits functions and measurements to be routed efficiently among the limited package pins while preserving CPU time for control algorithms.
Designers should allocate decoupling and analog grounding carefully because the ADC, CTMU, and motor-control peripherals may share a compact 20-pin board area. Motor power-stage switching should remain physically separated from sensitive control traces, and protection should cover transient, reverse-voltage, and ESD events. The PIC24FJ32MC101-E/P is particularly appropriate when a through-hole 20-pin package, 32 MHz processing, and dedicated motor-control peripherals are required in the same device.
This product page combines the manufacturer family information with package, memory, interface, temperature, and purchasing details. It also provides application guidance, design considerations, and a strict drop-in assessment so engineers can distinguish electrically similar controllers from genuine pin-compatible replacements.

主な用途
PIC24FJ32MC101-E/P の用途: 6 件s: Compact Brushed Motor Controller, Low-Power Pump Controller, Portable Power-Tool Controller, Automotive Accessory Motor Control, Industrial Fan and Actuator Module, Educational Motor-Control Platform.
Compact Brushed Motor Controller
The PIC24FJ32MC101-E/P fits compact brushed DC motor controllers because its 32 MHz PIC24 CPU provides 16 MIPS of throughput while MCPWM peripherals handle deterministic switching functions. The 3.0 V to 3.6 V operating range aligns with typical low-voltage motor-control power systems, and the 10-bit ADC can supervise current or speed feedback. Its 32 KB Flash and 2 KB SRAM provide space for control algorithms, fault handling, and communication buffers without moving the controller into a larger package.
おすすめ
Low-Power Pump Controller
The PIC24FJ32MC101-E/P is suitable for small pump and fluid-system controllers where deterministic PWM output, closed-loop feedback, and serial diagnostics are needed. Its 10-bit ADC can digitize pressure, level, or current feedback, while UART, SPI, and I2C provide flexible links to a sensor, display, or service interface. The 32 MHz CPU leaves processing headroom for soft-start routines, dry-run detection, and fault recovery, while the 20-pin PDIP package simplifies through-hole assembly and field service.
おすすめ
Portable Power-Tool Controller
The PIC24FJ32MC101-E/P works well in portable power tools and appliances where a compact 20-pin controller must coordinate motor drive, trigger input, and protection functions. Its MCPWM resources and peripheral pin selection help place motor-control functions on the available pins, while 15 I/O lines support buttons, hall sensors, status indicators, and serial programming. The -40 °C to +125 °C rating and AEC-Q100 identification also suit demanding environments when the complete product is validated for its intended duty cycle.
おすすめ
Automotive Accessory Motor Control
The PIC24FJ32MC101-E/P can support compact automotive accessory functions such as pumps, valves, small fans, and positioning actuators. The AEC-Q100 identification, enhanced -40 °C to +125 °C temperature range, and dedicated motor-control peripherals allow one controller to coordinate PWM drive and analog feedback. Its 3.0 V to 3.6 V supply operates directly in regulated 3.3 V automotive subsystems, while UART or SPI can link the controller to a body or powertrain controller for diagnostics and coordinated shutdown.
おすすめ
Industrial Fan and Actuator Module
The PIC24FJ32MC101-E/P is appropriate for modular industrial fans, dampers, and small actuators where local control reduces wiring and improves responsiveness. Its 16 MIPS performance can execute PID loops, ramp profiles, and sensor filtering while MCPWM generates the actuator command. The 15 I/O lines allow digital encoders, limit switches, interlocks, and status LEDs to share the controller, and the serial interfaces permit configuration, telemetry, or service communication with a higher-level controller.
おすすめ
Educational Motor-Control Platform
The PIC24FJ32MC101-E/P offers an accessible platform for learning PIC24 programming, PWM generation, ADC feedback, and motor-control sequencing. Its 20-pin PDIP package is easy to prototype on a breadboard or through-hole training board, while 32 KB Flash and 2 KB SRAM permit structured examples, diagnostic state machines, and communication experiments. The manufacturer data sheet covers the PIC24 CPU, CTMU, MCPWM, and PPS resources, providing a coherent reference for comparing motor-control techniques before moving to a production design.

設計ノート
Place the required bypass capacitors close to the PIC24FJ32MC101-E/P power and ground pins, and provide a quiet return path for ADC and CTMU signals. The 20-pin PDIP footprint offers generous through-hole spacing, but motor-drive traces can still couple into adjacent analog inputs. Route high-current switching paths away from the controller and use a clear separation between the power stage and measurement network.
Assign motor-control outputs, ADC inputs, serial signals, and programming interfaces from the manufacturer pin-description table before fixing the PCB layout. Peripheral pin selection can change signal routing options, so finalize the pin plan and firmware requirements together. Keep programming and debug access reachable, maintain consistent ground references between the microcontroller and analog sensor circuitry, and verify that external motor-driver fault signals can deactivate the power stage.
Do not substitute a related PIC24FJ16MC101 or a controller in another package without checking memory capacity, pin functions, and firmware support. The PIC24FJ32MC101-E/P requires a 3.0 V to 3.6 V operating environment, and its 20-pin PDIP package is not interchangeable with small-outline variants. Also avoid deriving motor current directly from an unfiltered ADC channel when accurate protection depends on fast, repeatable current measurements.
Treat the motor power stage and control PCB as separate electromagnetic domains. Use short gate-drive paths, maintain a compact motor-current loop, and apply filtering at sensor inputs so PWM edges do not corrupt feedback readings. If the motor and controller share a harness, separate motor current from sensor wiring and consider filtering and shielding at the analog input connector. Validate the completed assembly with an oscilloscope under worst-case duty cycle and supply transients.
