PIC24F08KM102-I/SO 개요
A microcontroller (MCU) is a single-chip computer containing a CPU, memory, and programmable I/O peripherals integrated on one die. The PIC24F family sits within the 16-bit microcontroller hierarchy: 16-bit MCU -> MCU -> embedded processor -> semiconductor. PIC24F devices extend 8-bit PIC architectures into higher-performance applications requiring more code space and richer peripherals while preserving low power consumption.
Key features include 16 MIPS throughput at 32 MHz, nanoWatt XLP sleep modes that extend battery life into the microamp range, and integrated peripherals that reduce external component count. The Configurable Logic Cell allows combinational and sequential logic to be implemented inside the MCU without external gates, while the 12-bit ADC provides up to 500 ksps conversion speed for sensor signal acquisition.
Typical applications include low-power sensor nodes, consumer appliances, building automation controllers, USB/CDC human-interface devices, and battery-powered instrumentation. The 28-SOIC wide-body footprint eases hand-soldering for prototypes and supports straightforward integration on two-layer boards for cost-sensitive designs.
When designing with this device, place a 100 nF decoupling capacitor within 2 mm of every VDD pin and reserve dedicated ground copper for analog and digital returns to maximize ADC accuracy. Configure unused I/O as outputs low to minimize current leakage and enable the on-chip voltage regulator configuration for the widest operating range.

일반적인 애플리케이션
PIC24F08KM102-I/SO 적합 용도: 7 애플리케이션s: Battery-Powered IoT Sensor Nodes, Consumer Appliance Control, Building Automation Controllers, USB Human-Interface Devices, Portable Medical Monitoring, Industrial Sensor Transmitters, Educational and Maker Projects.
Battery-Powered IoT Sensor Nodes
The PIC24F08KM102-I/SO is purpose-built for battery-powered IoT sensor nodes because its nanoWatt XLP architecture drops quiescent current into the nanoamp range during deep sleep, while the Configurable Logic Cell (CLC) lets wake-on-event logic run without waking the CPU. The 12-bit ADC handles typical sensor signal chains (temperature, humidity, battery voltage) at the 8 KB Flash / 1 KB RAM budget appropriate for lightweight IoT protocols such as Modbus RTU, BLE through an external module, or LoRaWAN over UART. Designers gain 16 MIPS of throughput when the CPU does wake up, which is plenty for periodic sensor reads and short transmissions, while still preserving multi-year coin-cell life.
추천
Consumer Appliance Control
In consumer appliances such as coffee machines, washing-machine front panels, and small kitchen devices, the PIC24F08KM102-I/SO provides reliable touch-button decoding and small-display drive through its MCCP/SCCP PWM modules. The 1.8-3.6 V supply range interfaces directly with 3.3 V peripherals and runs on 2x AA cells for portable appliances. The 28-SOIC package is hand-solder-friendly, which keeps prototype and rework costs low for early-stage product development, and the on-chip comparators enable direct zero-cross detection for triac-based mains control without external amplifiers.
추천
Building Automation Controllers
Building automation subsystems such as HVAC dampers, occupancy sensors, and lighting controllers benefit from the PIC24F08KM102-I/SO's combination of multiple PWM channels for LED dimming, a 12-bit ADC for light-level and temperature sensing, and the Configurable Logic Cell for hardware debouncing of mechanical switches. The 1 KB RAM and 8 KB Flash comfortably run BACnet MS/TP or Modbus slave firmware stacks when paired with an external RS-485 transceiver. Industrial-grade -40 C to +85 C operation ensures reliability in unconditioned electrical closets and rooftop equipment rooms.
추천
USB Human-Interface Devices
The PIC24F08KM102-I/SO can act as a low-cost USB HID class device (keyboard, mouse, consumer-control) when paired with an external USB transceiver and Microchip's USB stack. The 16 MIPS throughput at 32 MHz easily handles HID polling at 1 kHz and basic capacitive-touch or matrix-scanning firmware. The CLC offloads button-debouncing and key-combo logic, freeing CPU cycles for protocol handling. Using internal RC oscillator for USB keeps external component count minimal - typically just two I/O lines, the USB transceiver, and a few passives.
추천
Portable Medical Monitoring
Portable medical monitoring devices such as pulse oximeters, infrared thermometers, and pill-dispenser alarms use the PIC24F08KM102-I/SO because its low-power XLP modes preserve battery life for handheld use, while the 12-bit ADC digitizes sensor outputs with sufficient resolution for trend logging. The Configurable Logic Cell implements hardware watchdog-style safety interlocks that remain active even in deep sleep, satisfying basic medical-device fail-safe requirements. Note: this part is not FDA-cleared; designers must still perform full IEC 60601-1 system validation on the end product.
추천
Industrial Sensor Transmitters
Industrial 4-20 mA loop-powered or two-wire sensor transmitters leverage the PIC24F08KM102-I/SO's low quiescent current and 12-bit ADC to digitize bridge, RTD, or thermocouple signals within strict power budgets. The PWM modules can synthesize a 4-20 mA loop output when combined with a current mirror, or drive an HART modem's FSK carrier through an external analog front end. Industrial -40 C to +85 C operation tolerates factory-floor conditions, and the 28-SOIC package is robust against the conformal-coating and vibration environments typical of process plants.
추천
Educational and Maker Projects
The PIC24F08KM102-I/SO is widely used in university embedded-systems courses and maker projects thanks to its free Microchip MPLAB X IDE, free XC16 compiler, and broad library support (MCC code generator, Harmony). The 28-SOIC wide-body footprint fits standard 0.1 inch pitch breadboard adapter PCBs, which makes classroom wiring straightforward. The CLC peripheral is a popular teaching tool for introducing hardware-state-machine concepts without requiring students to learn FPGA tools first. Project examples include line-following robots, weather stations, and programmable power-supply controllers.

설계 노트
Estimated: Place a 100 nF X7R decoupling capacitor within 2 mm of every VDD pin (pins 13 and 28) and a single 10 uF bulk capacitor at the board entry. The internal voltage regulator generates 1.2 V for the core; do not draw external load current from this rail. For deep-sleep designs, leave unused pins configured as digital outputs driving low to avoid floating-input leakage currents that can waste microamps of supply current.
The 28-SOIC wide-body (7.50 mm) package requires a 1.27 mm pitch land pattern with pad width approximately 0.65 mm and length 1.85 mm. Keep the analog AVSS/AVDD traces short and surrounded by a ground pour to maximize 12-bit ADC accuracy. Route the 32 MHz crystal traces (OSC1/OSC2) symmetrically, surrounded by ground, and keep them under 5 mm if the on-chip PLL is engaged.
Do not assume the MCLR pin is optional - it must be pulled high through a 10 kohm resistor for normal operation; leaving it floating causes random resets. Programming pins PGEC1/PGED1 share RB1/RB0, so if those pins are used for other functions, ensure the in-circuit serial programmer (ICSP) connector is isolated by diodes or a programming header to avoid contention. The internal RC oscillator is factory-trimmed to within +/-2% but drifts over temperature; calibrate FRC using the FPLL for UART communications.
Estimated: At 32 MHz and 3.3 V, the PIC24F08KM102-I/SO typically draws 8-12 mA active and 30-60 nA in deep sleep, so power dissipation at 3.3 V full activity is approximately 25-40 mW. The 28-SOIC package has a theta_JA of approximately 85 C/W, which at room temperature yields a junction rise of only 2-3 C - thermal management is rarely needed unless the device is mounted inside a sealed enclosure with no air flow.
