PIC24FJ16MC101-I/SS 개요
What is a motor-control MCU? A motor-control microcontroller is a specialized MCU that integrates both a general-purpose CPU and dedicated motor-control peripherals such as high-resolution Pulse-Width Modulators (PWMs), Motor Control PWMs (MCPWMs), analog comparators with DAC references, operational amplifiers for current sensing, and peripherals like the Charge Time Measurement Unit (CTMU) for touch and sensor feedback. Motor-control MCUs sit inside the broader taxonomy of embedded microcontrollers, then microcontrollers, then microprocessors and SoCs, and ultimately fall under the Integrated Circuits > Microcontrollers category. The PIC24FJ16MC101 belongs to the PIC24F family, which uses a 16-bit modified Harvard architecture with separate program and data buses.
Key features include up to 16 MIPS throughput at 32 MHz, three 16-bit MCPWM channels with complementary outputs and programmable dead time, three 16-bit timers, a 10/12-bit ADC with up to 9 channels, two comparators with 10-bit DAC references, two op amps for in-line current sensing, an integrated CTMU, and Peripheral Pin Select (PPS) that remaps most digital I/O to nearly any pin. The device operates from 3.0 V to 5.5 V, supports 16 MIPS at 3.3 V, and includes a 10-bit ADC with 500 ksps conversion rate, dual comparators, and a 5-bit DAC for programmable threshold generation.
The PIC24FJ16MC101 architecture pairs a 16-bit CPU with a flexible peripheral set, eliminating external gate-driver logic and reducing PCB area. PPS enables late-stage pin assignment changes, which shortens hardware iterations. The device also integrates I2C, SPI, and UART interfaces for sensor and host communication, plus a Charge Time Measurement Unit (CTMU) that supports capacitive touch sensing and precise time-of-flight measurements.
Typical applications include sensorless BLDC ceiling fans, low-voltage cordless power tools, small drone ESCs (electronic speed controllers), appliance pumps and valves, and cost-optimized industrial pumps. The combination of MCPWM, op amps, and comparators on a single die eliminates the need for an external analog front-end in many 3-phase or 1-phase motor designs.
When designing with this part, populate both AVSS and AGND nets separately to the ground plane and place the Vcap decoupling capacitor within 5 mm of the dedicated Vcap pin. Programming is supported by Microchip's MPLAB X IDE and the MPLAB XC16 compiler; designers should use the MPLAB Code Configurator to initialize PPS and MCPWM modules.

일반적인 애플리케이션
PIC24FJ16MC101-I/SS 적합 용도: 6 애플리케이션s: Sensorless BLDC Ceiling Fan, Cordless Power Tool Motor Control, Small Drone ESC (Electronic Speed Controller), Appliance Pump and Valve Drive, Industrial Pump Variable-Frequency Drive, Capacitive Touch User Interface for Motorized Appliances.
Sensorless BLDC Ceiling Fan
The PIC24FJ16MC101-I/SS is a strong fit for cost-optimized sensorless BLDC ceiling fans where the three MCPWM channels drive a 3-phase half-bridge and the dual op amps inline-sense phase currents without external analog front-ends. The CTMU backs timer-based BEMF zero-crossing detection, avoiding dedicated BEMF comparators. PPS lets designers reassign PWM outputs to spare pins late in development, reducing board spins. Running sensorless 6-step commutation at 16 MIPS leaves headroom for UART-based remote control parsing and optional LED dimming. The 16 KB Flash accommodates Microchip AN1083 sensorless code plus application-level state machines, and the 1 KB SRAM is sufficient when the call stack is held small.

Cordless Power Tool Motor Control
For cordless drill and impact-driver electronics, the PIC24FJ16MC101-I/SS delivers 16 MIPS to handle back-EMF-based speed estimation and torque control via the three MCPWM outputs. The dual comparators with 10-bit DAC refs enable programmable current-limit thresholds for stall protection without external DACs, while the two on-chip op amps support in-line current sensing directly from low-side shunts. PPS allows designers to relocate PWM and ADC channels late in the design, which is critical when adapting the same firmware across 12 V, 18 V, and 20 V MAX battery platforms. The 3.0-5.5 V operating range is compatible with a single-cell Li-ion to 5-cell Li-ion stack after regulation.

Small Drone ESC (Electronic Speed Controller)
In hobby-class drone ESCs where cost and weight dominate BOM decisions, the PIC24FJ16MC101-I/SS integrates MCPWM, op amps, and CTMU into one 20-pin SSOP — eliminating the analog front-end and shrinking PCB area. Running at 16 MIPS supports fast PWM switching (typically 24-32 kHz) and active freewheeling for FOC lite or 6-step commutation. CTMU provides a hardware-timed input capture for BEMF zero-crossing detection that frees CPU cycles for throttle mixing. PPS enables PCB routing optimizations that are critical for compact 4-in-1 ESC boards. The 16 KB Flash holds the FOC lite algorithm plus bootloader for field firmware updates via UART.

Appliance Pump and Valve Drive
The PIC24FJ16MC101-I/SS suits appliance pumps, washing-machine drain pumps, and dishwasher diverter valves that demand reliable BLDC or PMSM control in a small footprint. The three MCPWM channels drive a 3-phase bridge; the dual comparators with 10-bit DACs support overcurrent and dry-run detection without external analog components. Industrial -40C to +85C operation handles under-hood and chassis-mount environments. With 16 KB Flash the firmware can host both sensorless startup and fault-recovery state machines. UART or I2C interfaces enable integration with the appliance main controller.
추천
Industrial Pump Variable-Frequency Drive
Small industrial dosing pumps and peristaltic drives benefit from the PIC24FJ16MC101-I/SS on-chip op amps and comparators that close the current loop directly without external amplifiers. The MCPWM generates the variable-frequency drive waveform with programmable dead time, preventing shoot-through in the half-bridge. Industrial -40C to +85C operation supports outdoor enclosures. The 16 MIPS CPU runs Microchip application notes AN1078 (sensorless FOC) for smoother torque and lower acoustic noise. PPS remaps peripheral pins late in the layout cycle, which is valuable for fluid-handling PCBs where mechanical constraints dictate placement.

Capacitive Touch User Interface for Motorized Appliances
The PIC24FJ16MC101-I/SS integrates the Charge Time Measurement Unit (CTMU) that powers capacitive touch buttons and sliders without dedicated touch ICs. In a motorized coffee grinder or blender, the CTMU reads 4-6 touch pads alongside the MCPWM controlling the BLDC motor — eliminating the second IC that would otherwise be required. The 10-bit ADC with up to 9 channels reads motor current and temperature, while PPS routes I2C to the board edge for the display. The 16 KB Flash holds both the motor-control loop and the touch firmware, and 1 KB RAM is sufficient when touch events are queued rather than buffered wholesale.

설계 노트
Place the Vcap decoupling capacitor (typically 10 uF ceramic) within 5 mm of the dedicated Vcap pin (SSOP pin 20 on some variants; refer to datasheet DS30009728). Route AVSS directly to the ground plane with a separate trace that joins digital ground only at the power-supply return. Place analog input RC filter components within 5 mm of the input pin to avoid pickup from switching PWM traces.
Route MCPWM output traces as differential pairs (PWMxH/PWMxL) with matched length to avoid timing skew across the half-bridge; skew >5 ns can cause shoot-through. Keep analog op-amp feedback traces short and away from PWM switching nodes. The CTMU channel capacitance lines should be guarded by ground traces to prevent motor noise coupling into touch measurements.
Do not skip configuring the PPS registers before relying on PWM outputs — pins default to GPIO on reset. Also configure the PWMLOCK bit before updating the MCPWM control registers, otherwise writes are silently ignored. When using the internal FRC oscillator for motor control, ensure the PLL is locked before enabling MCPWM output, or PWM frequency will drift during startup causing audible motor noise.
At 32 MHz full MIPS load, the PIC24FJ16MC101-I/SS dissipates roughly 30 mW — thermal management is rarely a concern. However, in 20-pin SSOP (5.30 mm body) designs the exposed thermal pad is not present, so verify that the surrounding copper area is sufficient to keep junction temperature below 125C in enclosed appliance enclosures. Estimated: T_J rise above ambient is approximately 3-5 C with 100 mm^2 of top-side copper.
규정 준수 정보
RoHS compliant per Microchip product page and DigiKey SKU 2712476 listing. Not AEC-Q100 qualified in the -I/SS industrial grade; the -E/SS extended temperature variant (-40C to +125C) is not automotive-qualified either — for AEC-Q100 designs use dsPIC33 variants.
