PIC24F08KM202T-I/ML Übersicht
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, peripherals, and I/O. The 16-bit PIC24F architecture sits between 8-bit PIC MCUs and 32-bit PIC32 devices in Microchip's portfolio, offering higher code density, wider data paths, and DSP-like instructions while retaining the PIC ecosystem's low power characteristics. The PIC24F KM family in particular targets mixed-signal embedded designs that need on-chip analog functions alongside digital control, reducing external component count and BOM cost.
Key features: 8 KB self-programmable Flash, 2 KB SRAM, 512 B EEPROM, 32 MHz operation delivering 16 MIPS, 19 channels of 12-bit ADC, 2 channels of 8-bit DAC, integrated op amps, comparators, Configurable Logic Cell (CLC), MCCP/SCCP timers, and peripheral trigger generator. XLP technology yields nanoWatt sleep currents suited for battery-powered and energy-harvesting applications. The 28-QFN (6x6 mm) footprint keeps the BOM footprint small.
Architecturally, the PIC24F uses a 16-bit modified Harvard CPU with single-cycle 16x16 MAC, supporting C-compiled code with predictable interrupt latency. The peripheral trigger generator and CLC allow hardware-based signal routing without CPU intervention, freeing the core for application logic and reducing firmware complexity.
Typical applications: portable medical and consumer devices, IoT sensor nodes, low-power wireless remote controls, battery monitoring and management, e-metering, and small-format industrial sensors. The combination of on-chip analog (12-bit ADC, 8-bit DAC, op amps) and flexible digital peripherals (CLC, MCCP/SCCP) makes the device a good fit for sensor conditioning and closed-loop regulation loops in compact designs.
Design consideration: at 32 MHz with 3.3 V supply the core current is in the single-digit mA range; sleep currents in the nanoWatt regime enable duty-cycled battery operation. Plan the ADC acquisition timing and reference decoupling around the integrated analog peripherals.

Typische Anwendungen
PIC24F08KM202T-I/ML ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, Portable Medical Monitoring Device, Industrial Sensor Conditioning and Loop Control, Low-Power Wireless Remote Control, Smart Home and Building Automation, Consumer Audio and Mixed-Signal Display Control.
Battery-Powered IoT Sensor Node
The PIC24F08KM202T-I/ML fits IoT sensor nodes because its XLP nanoWatt sleep currents keep quiescent draw in the nanoampere range between measurement bursts, directly extending battery life. Its 1.8-5.5 V supply range accepts a single Li-ion cell or 2xAA pack without a boost regulator. The 19-channel 12-bit ADC and integrated op amps condition thermocouple, strain-gauge, or electrochemical sensor signals on-chip, eliminating external analog front-ends. Configurable Logic Cell (CLC) handles wake-up event routing without waking the CPU, and the 8 KB Flash runs simple LoRaWAN or BLE beacon stacks.
Empfohlen
Portable Medical Monitoring Device
The PIC24F08KM202T-I/ML suits portable patient monitors where low noise, deterministic response, and low power matter. Its integrated 12-bit ADC, 8-bit DAC, and op amps condition ECG/PPG/biopotential signals directly, reducing analog BOM. The 16 MIPS performance runs R-peak detection and basic arrhythmia algorithms in real time at 32 MHz, while industrial -40 to +85 °C operation tolerates skin-contact thermal rise. XLP sleep between samples keeps average current in the microampere range, allowing multi-day battery operation for wearable pulse oximeters or glucose patch designs.
Empfohlen
Industrial Sensor Conditioning and Loop Control
The PIC24F08KM202T-I/ML is a strong fit for industrial 4-20 mA loop transmitters and process sensor conditioners thanks to its integrated op amps (programmable gain), 12-bit ADC, and 8-bit DACs. The wide 1.8-5.5 V supply tolerates 24 V loop drop after regulation, and CLC logic implements hardware-based interlocks that bypass CPU latency for safety-critical trip thresholds. MCCP/SCCP timers support PWM-based proportional outputs, while 24 I/O lines interface to keypads, displays, and HART modems. The 28-QFN footprint suits compact DIN-A-3 sensor head enclosures.
Empfohlen
Low-Power Wireless Remote Control
The PIC24F08KM202T-I/ML serves low-power wireless remotes (Sub-GHz, BLE, proprietary RF) because its XLP sleep modes keep idle current below 1 µA while waiting for user input, and it wakes within microseconds on CLC interrupt events. The 16-bit PIC core runs encoder/scanner firmware and rolling-code security algorithms, while CLC debounces key matrices in hardware before waking the core. Its 1.8-5.5 V range accepts a single coin cell or 2xAAA battery, and the 28-QFN fits behind a membrane keypad without adding thickness.
Empfohlen
Smart Home and Building Automation
For smart-home sensor and actuator nodes (thermostats, occupancy sensors, smart dimmers) the PIC24F08KM202T-I/ML integrates the analog chain (ADC, op amps, DAC) on-chip and drives TRIAC/LED PWM directly through its MCCP/SCCP modules. CLC implements zero-cross detect and dimming phase control in hardware, freeing the CPU for higher-level protocols. The 8 KB Flash fits simple Zigbee/Z-Wave/BLE bridge or Matter-ready application code, and XLP sleep keeps battery-powered door/window sensors running for years. The 28-QFN (6x6 mm) supports compact in-fixture designs.
Empfohlen
Consumer Audio and Mixed-Signal Display Control
The PIC24F08KM202T-I/ML fits small consumer audio and display peripherals (Bluetooth speakers, LED controllers, simple HMI panels) where its DAC, op amps, and PWM combine to drive LEDs or small Class-D audio stages. CLC implements audio routing and pulse-density modulation in hardware. The 16 MIPS core runs audio effect DSP and LED pattern generation, while XLP extends portable playback on a single Li-ion cell. The 28-QFN (6x6 mm) keeps the footprint small for tight consumer enclosures.

Designhinweise
The PIC24F08KM202T-I/ML's XLP nanoWatt sleep modes require careful peripheral gating before entry. Estimated: with the ADC and op amps disabled and the CPU in Sleep, the datasheet's typical Sleep current is in the nanoampere range; leaving any analog peripheral active can push sleep current into the microampere range and erase the XLP benefit. Always disable unused analog modules in firmware before WFI/Sleep entry and verify with a µCurrent probe on a populated board.
The 28-QFN (6x6 mm) package has an exposed thermal pad that MUST be soldered to a copper pour on the PCB. Estimated: with the EP soldered to at least 1 cm² of 2-oz copper, the datasheet's thermal resistance θJA drops by roughly 30-40 % versus an unsoldered EP. Connect the EP to the ground plane with multiple thermal vias for best heat spreading. Decouple VDD with a 100 nF ceramic capacitor placed within 3 mm of the VDD pin, plus a bulk 4.7 µF capacitor on the same net.
When using the integrated 12-bit ADC, drive the analog inputs through an RC low-pass filter (typically 1 kΩ + 100 nF) to limit broadband noise folding into the ADC bandwidth. Estimated: at 32 MHz system clock the ADC's effective number of bits (ENOB) can drop by 1-2 LSB if the analog source impedance exceeds the datasheet's recommended maximum. The integrated op amps help buffer high-impedance sensors, but always route analog traces away from digital switching lines and keep the analog ground island contiguous with the EP ground.
A common pitfall is forgetting to configure the Configuration bits for the oscillator mode; leaving the default FRC (internal 8 MHz) without proper PLL setup will lock the firmware at 8 MHz instead of the intended 32 MHz. Always set the Configuration bits in the IDE project properties to match the hardware crystal/oscillator configuration. Another common error is leaving the MCLR pin floating; if MCLR is unused, tie it to VDD through a 10 kΩ resistor to prevent spurious resets from noise.
