PIC24F08KM102-E/ML - 32MHz 8KB Flash 28-QFN | Microchip
N.º de pieza: PIC24F08KM102-E/ML ✓ ActivoPIC24F08KM102-E/ML Descripción general
A microcontroller is a programmable semiconductor that integrates a CPU, memory, and peripherals into one device for embedded control. The PIC24F08KM102 belongs to the Microchip PIC24F family and combines a 16-bit core with analog signal conversion and low-power operation. Its 28-QFN surface-mount package supports space-constrained products while retaining enough I/O and analog resources for sensor reading, actuator control, and embedded communications.
The 32 MHz core provides faster instruction execution than lower-clock microcontroller designs, while the 8 KB Flash capacity stores application firmware. The 1 KB SRAM provides working memory and the 512-byte EEPROM supports nonvolatile parameter retention. According to the Microchip manufacturer product page, the integrated peripherals include a 12-bit ADC, DAC, op amps, and comparators, reducing the external component count in analog signal-chain designs.
The device uses a 1.8 V to 5.5 V operating range, allowing operation from low-voltage battery-derived rails and conventional 3.3 V or 5 V systems. Integrated MCCP and SCCP communication peripherals support serial interface requirements, while the analog block allows a design to measure inputs and generate an analog output without separate converter ICs. Exact converter channel counts, pin assignments, and electrical limits should be confirmed against the manufacturer pin-description and electrical-characteristics tables before layout release.
Typical uses include industrial sensor nodes, compact environmental monitors, building-control modules, compact motor controllers, battery-powered instruments, and low-cost embedded control boards. The small package is particularly useful where board area is limited but the design still needs programmable control, data acquisition, and a calibrated analog output in one device.
Design the decoupling network around the manufacturer power-pin recommendations and keep analog inputs short, shielded where appropriate, and away from fast-switching traces. Confirm the exposed-pad connection, operating voltage range, available I/O, and peripheral multiplexing against the exact -E/ML package variant before compiling firmware or releasing a PCB footprint.
This page combines manufacturer specifications, practical application guidance, package information, and qualified same-family alternatives to support component selection, PCB planning, and replacement decisions for the PIC24F08KM102-E/ML.

Aplicaciones típicas
PIC24F08KM102-E/ML es adecuado para 6 aplicacións: Low-Voltage Environmental Sensor Node, Compact Industrial Control Module, Battery-Powered Measurement Instrument, Building Control and HVAC Interface, Compact Motor and Actuator Controller, Programmable Analog Output Controller.
Low-Voltage Environmental Sensor Node
The PIC24F08KM102-E/ML fits an environmental sensor node that must measure analog inputs while conserving power. Its 1.8 V to 5.5 V operating range supports low-energy sensor rails, while the 12-bit ADC provides the conversion function needed for temperature, humidity, or air-quality sensing. The 32 MHz core can manage sampling, filtering, configuration, and communication tasks, and the integrated comparator can provide a simple threshold function. The principal design limit is the 8 KB Flash capacity, which favors compact firmware and table-driven control logic.
Recomendado
Compact Industrial Control Module
The PIC24F08KM102-E/ML is appropriate for compact industrial control modules that combine sensor acquisition, threshold decisions, and actuator outputs. Its 16-bit core runs at 32 MHz, providing useful processing headroom for control logic, while 1 KB SRAM supports working buffers and 512 bytes of EEPROM can retain calibration or configuration values. The integrated 12-bit ADC, DAC, op amps, and comparator reduce board area. Designers should still verify available I/O and ensure that motor or relay transients remain outside sensitive analog and MCU supply pins.
Recomendado
Battery-Powered Measurement Instrument
The PIC24F08KM102-E/ML can serve as the controller in a battery-powered measurement instrument where low supply voltage and integrated analog functions are important. Operation from 1.8 V to 5.5 V enables use with low-voltage cells or regulated rails, and the 12-bit ADC supports common sensor and resistive-divider measurement stages. The DAC permits simple analog excitation or reference generation, while the 1 KB RAM supports working calculations. Firmware must keep buffering and logging within the 1 KB SRAM and 8 KB Flash limits while accounting for radio and display loads in the power budget.
Recomendado
Building Control and HVAC Interface
The PIC24F08KM102-E/ML is well suited to small building-control and HVAC interface boards that monitor sensors and control outputs. The 32 MHz 16-bit core can execute periodic sampling and control routines, the 12-bit ADC handles conditioned analog sensor signals, and the comparator supports independent threshold detection. Its 28-QFN 6 x 6 mm package leaves room for communication and relay-driver circuitry on a compact board. Confirm the exact -E/ML environmental grade and protect communication and output interfaces from inductive surges before deployment.
Recomendado
Compact Motor and Actuator Controller
The PIC24F08KM102-E/ML can coordinate a compact actuator or motor-control subsystem when the system requires programmable logic, sensor feedback, and an analog command path. The 32 MHz processor supports deterministic control tasks, the 12-bit ADC can digitize a current or position signal, and the DAC can generate a command voltage for an analog drive stage. The MCU should remain isolated from motor transients through appropriate driver circuitry, filtering, and separate return-current paths. The integrated analog block reduces signal-chain parts, but its 1 KB SRAM requires careful allocation for control state.
Recomendado
Programmable Analog Output Controller
The PIC24F08KM102-E/ML is suitable for programmable test, excitation, and analog-output products where the DAC and op amps simplify the signal chain. Its 32 MHz core can update set points and supervisory logic, while the integrated 12-bit ADC provides a measurement path for closed-loop control or output verification. The 1.8 V to 5.5 V range supports low-voltage portable equipment, and the compact 28-QFN package improves board utilization. Validate output settling, DAC reference requirements, and analog pin multiplexing in the manufacturer documentation before finalizing analog routing.

Notas de diseño
Follow the Microchip recommended decoupling network and connect the 28-QFN exposed pad according to the package land pattern and thermal guidance in the manufacturer documentation. Place input capacitors close to the corresponding supply pins and provide a short, low-impedance return path for analog ground currents. Confirm exposed-pad copper and solder-mask requirements against the selected board-assembly process before releasing fabrication data.
Route analog inputs away from switching nodes, high-current return paths, and digital clock signals. If the ADC monitors a sensitive sensor, use a quiet reference and ground arrangement, maintain short analog traces, and place any filtering network close to the MCU pin. The integrated op amps and comparator help reduce board area, but external resistor networks still require tolerance analysis because they directly influence scaling, offset, and threshold accuracy.
Do not assume every 28-QFN device with the same family name has identical multiplexing, peripheral assignments, or environmental ratings. Confirm the complete ordering code, supply limits, analog-pin configuration, startup behavior, and programming requirements for PIC24F08KM102-E/ML. The -E and -I ordering codes must match the product's required temperature grade, and firmware should be tested at the intended minimum and maximum operating voltages.
Estimate the average and peak supply demand using the MCU operating current, analog peripheral state, communication activity, and external load rather than a single nominal current value. For battery-powered equipment, include sensor, radio, and actuator loads in the complete power budget. The 1.8 V to 5.5 V operating range provides flexibility, but regulator efficiency, quiescent current, and startup current can determine whether a cell supports the intended service interval.
