PIC24F08KA102-I/ML Übersicht
What is a PIC24F XLP microcontroller? An XLP (eXtreme Low Power) microcontroller is a class of low-power MCU designed for sleep-current performance in the nanoampere range, integrating power-saving modes such as Deep Sleep, Sleep, Idle, and Doze with peripheral modules that can operate autonomously while the CPU is halted. Within Microchip's portfolio, the PIC24F XLP family sits between the 8-bit PIC16/PIC18 families and the higher-performance PIC24EP dsPIC families, offering 16-bit CPU performance at ultra-low sleep currents suitable for IoT edge nodes.
Key features of the PIC24F08KA102-I/ML include the nanoWatt XLP deep-sleep mode with Real-Time Clock/Calendar (RTCC) running from a dedicated 32 kHz crystal, hardware Real-Time Clock and Calendar, 4-channel DMA, 3-wire SPI/I2S, two I2C™ and two UART interfaces, a 10-bit ADC with up to 13 input channels and 500 ksps conversion rate, and four 16-bit timers. The device integrates a Charge Time Measurement Unit (CTMU) for capacitive touch sensing and a Peripheral Pin Select (PPS) system that remaps digital peripherals to any I/O pin, simplifying PCB layout.
Architecturally, the PIC24F08KA102 uses a modified Harvard architecture with a 16-bit wide datapath, 24-bit instructions, a single-cycle hardware multiplier, and a hardware divider supporting 32/16 and 16/16 signed and unsigned operations. The Flash program memory supports self-programmability under firmware control, enabling bootloaders and in-field firmware updates, while the data EEPROM supports up to 1M erase/write cycles and Flash supports up to 10K cycles endurance.
Typical applications include battery-powered sensor nodes, wearable health and fitness devices, remote controls, energy harvesting systems, capacitive touch user interfaces, low-power wireless sensor transmitters, and industrial IoT edge controllers. The wide operating temperature range of -40°C to +85°C (industrial grade) and the low typical sleep current (under 20 nA in Deep Sleep with RTCC) make it ideal for always-on applications.
When designing with this MCU, plan for an external 32.768 kHz crystal for the secondary oscillator (used by RTCC in Deep Sleep), select a 10 µF bulk + 0.1 µF decoupling pair near each VDD/VSS pair, and verify unused I/O configuration to prevent parasitic current paths in Deep Sleep mode. The PPS system must be initialized in firmware before peripheral use; failure to do so will leave peripherals disconnected from physical pins.

Typische Anwendungen
PIC24F08KA102-I/ML ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Node, Wearable Health Monitoring Band, Capacitive Touch User Interface, Remote Control / Home Automation, Industrial Sensor Transmitter, Energy-Harvesting Wireless Switch.
Battery-Powered IoT Sensor Node
The PIC24F08KA102-I/ML fits battery-powered IoT sensor nodes because its nanoWatt XLP Deep Sleep mode with the RTCC running from a secondary 32.768 kHz oscillator consumes a typical 20 nA. This allows a sensor node transmitting hourly from a CR2032 coin cell to operate for more than five years on a single battery. The 32 MHz/16 MIPS PIC24 core wakes the device, reads the sensor, processes the data, transmits via UART, and returns to Deep Sleep within milliseconds. The integrated 4-channel DMA offloads peripheral data movement while the CPU sleeps, and the Peripheral Pin Select (PPS) routes the UART to any I/O pin, eliminating the need for board respins when the antenna layout changes.
Empfohlen
Wearable Health Monitoring Band
Wearable health bands benefit from the PIC24F08KA102-I/ML because the device combines sub-20 nA Deep Sleep current with the CTMU peripheral, which performs capacitive touch sensing for buttons and proximity detection on the wearable housing. The integrated 10-bit ADC samples pulse-oximetry or body-temperature analog signals at 500 ksps, and the PPS system reassigns peripherals to the fewest possible I/O pins so the band can be built on a small PCB. With 8 KB Flash and 1.5 KB SRAM, the firmware fits heart-rate processing, BLE advertisement via a companion radio, and bootloader support. Industrial -40 C to +85 C operation covers the full skin-temperature and ambient range of body-worn use cases.
Empfohlen
Capacitive Touch User Interface
The PIC24F08KA102-I/ML is well-suited for capacitive touch keypads and sliders because its CTMU (Charge Time Measurement Unit) measures sub-picofarad capacitance changes through the 10-bit ADC at up to 500 ksps, supporting multi-button panels and slider tracks with a single MCU. The PPS system routes the touch channels to any GPIO, eliminating the rigid pin assignments of older touch controllers. The 32 MHz CPU performs touch decoding and debouncing within a few hundred microseconds, allowing the device to remain in Deep Sleep for the vast majority of the time. Industrial temperature grade ensures stable touch behavior in HVAC panels and outdoor kiosks.
Empfohlen
Remote Control / Home Automation
Infrared and RF remote controls for home automation rely on the PIC24F08KA102-I/ML because the part wakes from Deep Sleep on any I/O interrupt, transmits a button-press code via the UART or SPI/I2S interface, and returns to Deep Sleep in under a millisecond. With two UART interfaces and two I2C channels, the same MCU can drive an IR LED driver, read a MEMS accelerometer for gesture recognition, and interface to a small OLED display. The 8 KB Flash accommodates proprietary RF protocols and protocol stacks, and the 1.5 KB SRAM holds enough buffer space for display frames without external memory. Industrial temperature rating supports outdoor and automotive cabin use.
Empfohlen
Industrial Sensor Transmitter
Industrial 4-20 mA loop-powered sensor transmitters are well served by the PIC24F08KA102-I/ML because the nanoWatt XLP architecture allows the device to measure, linearize, and transmit data within the limited current budget of a 4-20 mA loop. The 10-bit ADC with 13 input channels multiplexes multiple sensor inputs such as pressure, temperature, and flow, while the integrated DMA transfers readings without CPU intervention. Industrial -40 C to +85 C operation covers most process environments, and the RTCC with Deep Sleep keeps the average current well below 3.5 mA even with periodic HART modulation via UART.
Empfohlen
Energy-Harvesting Wireless Switch
Energy-harvesting wireless light switches and door/window sensors fit the PIC24F08KA102-I/ML because its Deep Sleep current under 20 nA allows operation from the few hundred microjoules harvested per button press or per piezoelectric tap. The RTCC keeps time between events, and the integrated DMA wakes peripherals without the CPU. The PIC24 core processes the switch event, transmits an EnOcean-style or proprietary RF frame, and returns to Deep Sleep. The 8 KB Flash fits the application code plus bootloader, and 1.5 KB SRAM holds the transmit buffer.

Designhinweise
Estimated: at 3.3 V VDD with the CPU active at 32 MHz and all peripherals enabled, the PIC24F08KA102-I/ML draws approximately 8-10 mA. In Deep Sleep with RTCC running from SOSC, the typical current is under 20 nA per the datasheet, allowing a CR2032 coin cell (220 mAh) to power the device in always-on IoT nodes for more than five years assuming hourly wake events. Configure the DSBOR and DSWDT bits to further reduce Deep Sleep current where brown-out reset and watchdog are not required.
The 28-QFN (6x6 mm) package with exposed thermal pad requires the central EP to be soldered to a copper pour connected to VSS for both thermal dissipation and ground-return integrity. Place a 10 uF bulk decoupling capacitor near the VDD pin pair (pins 7 and 19) and a 0.1 uF ceramic cap adjacent to each VDD pin. Keep the 32.768 kHz SOSC crystal traces short and guarded by a ground ring to minimize clock jitter that would affect RTCC accuracy.
The Peripheral Pin Select (PPS) system must be unlocked and configured in firmware before any digital peripheral (UART, SPI, I2C, CTMU outputs) will drive the physical I/O pins. Failing to call the PPS unlock sequence leaves peripherals disconnected even though the peripheral module registers indicate successful configuration. Always initialize PPS immediately after POR, and lock PPS again after configuration to prevent runaway code from changing pin assignments.
For capacitive touch applications using the CTMU, route the touch electrodes as short PCB traces with a ground fill at least 5 mm from the electrode perimeter. The CTMU is sensitive to parasitic capacitance; keep the touch trace capacitance below 20 pF for reliable button detection. Adding a series resistor (1 kOhm to 10 kOhm) on each CTMU input pin reduces susceptibility to ESD and RF injection.
Compliance-Informationen
RoHS and REACH compliance per Microchip product page. Industrial temperature grade -40 C to +85 C; AEC-Q100 is not applicable to this commercial/industrial variant. Choose -E/ML for extended temperature grade.
