PIC24F16KM102-I/ML - 16-Bit 32MHz MCU | Microchip Technology
N.º da peça: PIC24F16KM102-I/ML ✓ AtivoPIC24F16KM102-I/ML Visão geral
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals on one device. The PIC24F family belongs to the broader embedded-controller hierarchy, combining general-purpose processing with timers, communication interfaces, analog conversion, and low-power control. This makes the PIC24F16KM102-I/ML suitable for applications in which local sensing, control, and communication must coexist on a small circuit board.
The device offers 16 KB of Flash memory, equivalent to 5.5K by 24 bits, and operates at 32 MHz. Its integrated features include a 12-bit ADC, comparators, flexible Capture/Compare/PWM modules, and Configurable Logic Cells. The family supports both 3 V and 5 V applications, while the PIC24FV naming used in one distributor listing identifies a related family variant with a 2.0 V to 5.5 V operating range. Confirm the exact electrical limits for the ordered MPN in the manufacturer documentation.
PIC24F16KM102-I/ML belongs to the low-pin-count PIC24F XLP portfolio, where XLP denotes nanoWart eXtreme low-power operation. Its architecture is intended to balance responsive processing with reduced energy consumption in battery-operated and intermittently powered equipment. Multiple programming and programming-verification pin pairs are available according to the device-specific programming information, so firmware tooling and PCB access must be planned before fabrication.
Typical uses include battery-powered environmental sensors, compact industrial monitoring equipment, consumer controls, LED lighting interfaces, and low-power embedded instruments. The 12-bit ADC supports analog measurement, the comparators support threshold detection, and the PWM peripherals can drive indicators or actuator controls. The small 6 mm by 6 mm QFN format also supports space-constrained products with dense mixed-signal layouts.
Design the decoupling network close to the supply pins and reserve adequate exposed-pad copper for thermal dissipation. Confirm programming connector access, pin multiplexing, analog reference requirements, and the exact voltage range for the selected ordering code before release. Treat the 28-QFN land pattern as unsuitable for direct assembly without a qualified PCB footprint and a deliberate package-orientation plan.
This product page combines the manufacturer's family-level characteristics with distributor-confirmed order information, a same-package comparison, and engineering guidance for low-power PCB design. It also distinguishes the target ordering code from package variants and similar family members that are not automatically drop-in replacements.

Aplicações típicas
PIC24F16KM102-I/ML é adequado para 6 aplicaçãos: Battery-Powered Environmental Sensor, Industrial Condition Monitoring, LED Lighting Control, Low-Power Consumer Control, Digital Control and Interface Hub, Portable Measurement Instrument.
Battery-Powered Environmental Sensor
The PIC24F16KM102-I/ML fits compact environmental sensors because it combines a 16-bit PIC24F processor, 16 KB of Flash, a 12-bit ADC, and nanoWatt eXtreme low-power capabilities. The ADC can digitize a resistive or ratiometric sensor output, while programmable digital peripherals support threshold detection and periodic wake-up behavior. At 32 MHz maximum frequency, the controller can process samples and format results without requiring a separate host processor. A practical design uses the ADC and comparators for sensor conditioning, places the MCU between sleep and active operating modes, and powers the sensor only during measurements. The principal trade-off is that firmware execution time and sensor current can dominate overall battery life, so the system should be scheduled around actual measurement intervals rather than continuous polling.
Recomendado
Industrial Condition Monitoring
PIC24F16KM102-I/ML is appropriate for industrial condition-monitoring modules that need local analog measurement and low-power control in a small board area. Its 12-bit ADC can capture sensor data, while comparators and the Configurable Logic Cell can establish local thresholds and combine digital events without continuous processor intervention. The 32 MHz maximum clock rate provides enough computational headroom for filtering, diagnostics, and communication formatting. The industrial-grade ordering designation supports use in industrial temperature conditions when the complete device limits are met. A robust implementation should isolate analog inputs from switching nodes, provide stable references, and use the comparator or external supervision for safe shutdown. Because the device is a low-pin-count MCU, careful pin multiplexing is necessary when both sensing and serial communication are required.
Recomendado
LED Lighting Control
The PIC24F16KM102-I/ML can control dimmable LED systems by using its flexible Capture/Compare/PWM modules to generate the required drive waveform. A microcontroller-based approach supports dimming profiles, status feedback, fault handling, and configurable logic without requiring a dedicated LED-driver IC for moderate current levels. The 16-bit architecture and 32 MHz maximum frequency are suitable for timing multiple channels and updating control parameters. In a practical design, the PWM output drives a suitable transistor or LED-driver stage rather than powering an LED string directly. The 12-bit ADC may also monitor a current-sensing or temperature signal, allowing closed-loop brightness control. Component selection must account for the LED load, switching frequency, thermal conditions, and whether the required dimming method is compatible with the selected PWM channel and pin mapping.
Recomendado
Low-Power Consumer Control
PIC24F16KM102-I/ML suits compact consumer controls where a small 28-QFN footprint, local logic, and low standby energy are more important than a high pin count. The controller can combine button or touch inputs, LEDs, timing functions, and a serial interface in a single device. Its 16 KB of Flash supports a focused control application with configuration storage and diagnostics, while the 12-bit ADC can monitor a analog control element such as a potentiometer. A typical implementation keeps the processor inactive between user events and uses the timer or an external interrupt to wake it for action. Product designers should define the exact sleep and wake behavior in firmware and ensure that all connected peripherals do not prevent the intended low-current state. Firmware update and programming access also need to remain practical in the final enclosure.
Recomendado
Digital Control and Interface Hub
The PIC24F16KM102-I/ML can serve as a compact digital control hub for a subsystem that requires several timers, configurable logic, and analog supervision. The Configurable Logic Cell is useful for deterministic event handling or combining peripheral outputs, while Capture/Compare/PWM modules support waveform generation and input capture. With a 32 MHz maximum processor frequency and 16 KB of program memory, the device is suited to coordinated control tasks rather than large protocol stacks or graphical interfaces. A practical implementation can use one PWM channel for an actuator, capture inputs for speed or position timing, and the ADC for feedback. Pin multiplexing and interrupt priorities should be planned early because the 28-pin package offers limited I/O. Programmable Logic Cell assignments and peripheral pin ownership must be confirmed against the device documentation for the exact configuration.
Recomendado
Portable Measurement Instrument
PIC24F16KM102-I/ML is useful in a portable measurement instrument that combines an analog input, timing functions, and compact user feedback. The 12-bit ADC can acquire the primary analog value, while comparators can implement threshold events and the PWM modules can generate excitation or reference waveforms. At 32 MHz maximum frequency, the controller can perform calibration, filtering, and display updates while preserving headroom for serial data transfer. A battery-operated implementation should sequence analog and digital power carefully and exploit the family's XLP characteristics between measurement cycles. The 28-QFN package also allows the instrument to remain small, although exposed-pad layout and programming access require deliberate planning. For measurements requiring greater resolution, accuracy, or channel count, the ADC specification should be compared with the instrument's actual signal-to-noise and calibration requirements.

Notas de projeto
Treat the 28-QFN HVQCCN footprint as a no-lead assembly package with a central exposed pad. Confirm the manufacturer's land pattern, solder-mask opening, and paste-aperture dimensions against the current package drawing before releasing Gerber files. Place input and output decoupling capacitors close to their associated device pins, and provide a continuous ground path beneath the exposed pad. Incorrect thermal-via placement can impair both soldering consistency and heat dissipation.
Separate analog and digital supply requirements during power-tree design, then use the exact electrical-characteristics table to confirm which supply pins may be connected together. Place bulk and local ceramic capacitance according to the recommended application circuit. If the analog section is sensitive to switching noise, route its return current away from PWM and high-current load paths. Review startup, sleep current, and operating current together rather than optimizing only active-mode consumption.
Preserve access to a matched programming pair because the device provides multiple PGEC and PGED options, and each pair must be used together. Mark the PCB orientation clearly because the 28-QFN has no obvious lead sequence. Keep the programming interface away from high-voltage isolation barriers, motor nodes, and antenna keep-out regions. Before fabrication, compare the schematic symbol pin numbers and names with the manufacturer's 28-QFN pin-description table.
Do not substitute a device merely because it has 16 KB of Flash and the same nominal package size. For each candidate, compare the pin table, exposed-pad connection, supply pins, programming pins, oscillator connections, analog-reference requirements, and peripheral multiplexing. Firmware built for one part may require changes even when the board remains physically compatible. Treat cross-reference candidates as design-review items until the application and programming requirements have been validated.
Informações de conformidade
Compliance status requires confirmation from the manufacturer product documentation for the exact ordering code. The -I suffix identifies the industrial-temperature option but does not by itself establish AEC-Q100 qualification.
