PIC24F08KL302-I/MQ Übersicht
A 16-bit microcontroller (MCU) is an embedded computing device with a 16-bit-wide data path, instruction set architecture (ISA), and registers. Compared with 8-bit MCUs, 16-bit devices offer higher code density, faster arithmetic, and richer peripherals while consuming less power than 32-bit Cortex-M parts. The PIC24F family sits in Microchip's nanoWatt XLP hierarchy: PIC10/12/16/18 (8-bit) -> PIC24F (16-bit low-power) -> PIC24E/dsPIC (16-bit high-performance / DSP). The 8KB Flash and 1KB RAM position this MCU between bare-bone 8-bit PICs and higher-end PIC24EP/dsPIC parts, targeting cost-sensitive applications that need 16-bit performance with eXtreme Low Power consumption.
Key features include three power-managed modes (Run, Idle, Sleep), multiple oscillator options (HFINTOSC 8 MHz with 4x PLL up to 32 MHz, LFINTOSC 31 kHz), up to 23 I/O pins, and CTMU for capacitive-touch and mTouch sensing. The wide 1.8V-3.6V VDD range supports battery-powered designs including single-cell Li-Ion and two-AA operation. Hardware capacitive-touch support and Sleep currents below typical XLP targets make it suited for always-on sensor nodes.
Architecture uses the 16-bit enhanced modified Harvard design with 24-bit instructions and 16-bit data, a 16-level hardware stack, and vectored interrupts. The 32 MHz system clock with PLL delivers 16 MIPS, sufficient for sensor-fusion edge algorithms, motor-control loops, and low-rate wireless protocol stacks. Cipher/HASH accelerators are absent, but CCP/ECCP provides PWM capture/compare for motor and lighting control.
Typical applications include low-power sensor hubs, capacitive touch HMIs, handheld instruments, battery-powered IoT edge nodes, and cost-sensitive motor/lighting controls. Its drop-in migration path to other PIC24F KL/KA devices preserves firmware and PCB design across product families.
When designing with the PIC24F08KL302-I/MQ, ensure ICD-capable pin assignments for in-circuit debug and reserve MCLR pull-up to meet Microchip programming-voltage requirements. Power-rail decoupling per datasheet recommendations (0.1 µF + bulk) is mandatory for ADC accuracy.

Typische Anwendungen
PIC24F08KL302-I/MQ ist geeignet für 7 Anwendungs: Low-Power IoT Sensor Hub, Capacitive Touch HMI, Battery-Powered Handheld Instrument, Cost-Sensitive LED Lighting Controller, Small Motor / Fan Speed Control, Wearable Fitness / Health Patch, Automotive Body / Accessory Module (non-safety).
Low-Power IoT Sensor Hub
The PIC24F08KL302-I/MQ fits IoT sensor hubs where sub-µA Sleep current and battery life dominate. With nanoWatt XLP technology under 350 µA/MHz at 1.8V and an integrated 10-bit ADC, it reads temperature, humidity, and motion sensors before returning to Sleep. Its 8 KB Flash handles ZigBee/LoRaWAN node firmware with margin; the 1 KB SRAM buffers pre-transmission payloads. Compared with 32-bit Cortex-M0+ alternatives, the KL302 draws less Sleep current while costing roughly 30% less.
Empfohlen
Capacitive Touch HMI
The CTMU peripheral and mTouch library make the PIC24F08KL302-I/MQ ideal for capacitive-touch HMIs on consumer appliances and entry-level industrial panels. With up to 23 I/O pins, it drives 8-12 touch channels plus LEDs or a small graphic OLED. The 16 MIPS CPU executes touch-scan plus debounce in real time, while XLP Sleep below 1 µA keeps battery-operated remote controls alive for years. Designers migrating from PIC18 can reuse firmware concepts thanks to PIC24F register compatibility.
Empfohlen
Battery-Powered Handheld Instrument
The 1.8-3.6 V VDD of the PIC24F08KL302-I/MQ supports direct 2x AA or single Li-Ion cell operation, ideal for handheld multimeters, environmental loggers, and medical spot-checkers. Run-mode current under 350 µA/MHz keeps continuous-logging battery life above 100 hours on 2x AA. The 32 MHz MIPS core computes RMS and peak-detect in real time; the 10-bit ADC at 9 channels covers voltage, current, and temperature inputs in one scan loop. Compared with discrete 8-bit PIC designs, the KL302 simplifies BOM with integrated EEPROM and stronger peripherals.
Empfohlen
Cost-Sensitive LED Lighting Controller
The PIC24F08KL302-I/MQ drives entry-level LED lighting controllers, where its CCP/ECCP peripheral generates PWM dimming up to 32 MHz without external timing ICs. The 8 KB Flash hosts DMX-512 or DALI lite stacks; 1 KB RAM buffers scene memory. Industrial temperature grade (-40 to +85 °C) supports outdoor fixtures, while XLP Sleep prevents parasitic drain when fixtures are off. The 28-QFN package fits behind COB LED carriers in 5x5 mm space.
Empfohlen
Small Motor / Fan Speed Control
Brushless DC and small stepper-motor controllers use the PIC24F08KL302-I/MQ for closed-loop speed regulation. Its ECCP module with PWM and fault inputs drives 3-phase BLDC commutation tables in firmware; the 16 MIPS core updates the PID loop every 50 µs. With 1.8-3.6 V operation, the MCU sits on a single-rail logic supply alongside gate drivers at 12-24 V. Designers targeting ceiling fans or pump controllers benefit from the same PCB for both 4 KB and 8 KB firmware variants within the KL family.
Empfohlen
Wearable Fitness / Health Patch
Wearable fitness patches and disposable health monitors fit the PIC24F08KL302-I/MQ due to its sub-µA Sleep current and 1.8 V minimum supply. The MCU sleeps between heart-rate or SpO2 samples, wakes via RTCC, reads the sensor via MSSP I²C, logs to 256 B EEPROM, and re-entits Sleep. With 8 KB Flash, firmware supports BLE-beacon advertising logic on a companion radio; the 28-QFN 5x5 mm package drops into coin-cell wearable PCBs. AEC-Q100 grade is not required, but industrial temperature range suffices.
Empfohlen
Automotive Body / Accessory Module (non-safety)
The PIC24F08KL302-I/MQ powers non-safety automotive body modules such as interior lighting, seat controllers, and accessory multiplexers. Operating across -40 to +85 °C handles cabin environments, and 1.8-3.6 V matches 12 V battery post-regulator rails. The MSSP peripheral drives LIN slaves or SPI-controlled LED drivers. For safety-critical applications (airbag, braking), migrate to PIC24F KA/Q automotive-grade parts; for body electronics, the KL302 is a cost-optimized fit.

Wichtigste Unterscheidungsmerkmale
- Highest Flash in 28-QFN PIC24F KL family at this I/O count (vs. PIC24F08KL301-I/MQ)
- nanoWatt XLP deep-Sleep current leadership (vs. PIC24F08KA102-I/MQ)
- 16-bit performance at 8-bit BOM cost (vs. PIC18F equivalent)
Designhinweise
Decouple VDD with a 0.1 µF ceramic capacitor placed within 5 mm of the VDD/VSS pins, plus a 1-10 µF bulk capacitor per Microchip datasheet recommendations. For battery designs, an MCP1700 LDO is preferred over switching regulators to avoid injecting noise into the 10-bit ADC readings. Estimated: at VDD=3.3 V with all peripherals disabled, Sleep current falls below 1 µA thanks to nanoWatt XLP technology.
The 28-QFN (MQ) package has an exposed thermal pad that must be soldered to a 5x5 mm copper pour on the top layer for thermal relief and ground reference. Maintain continuous ground returns under the MCU and avoid routing analog ADC traces across digital switching nodes. Recommended: 4-layer stackup with dedicated ground plane.
Do not exceed 32 MHz FOSC: configuring HFINTOSC + PLL while VDD < 2.7 V causes unstable operation per the Microchip datasheet. Verify MCLR is pulled up through 10 kΩ to VDD; omitting it prevents ICD programming. When migrating from PIC18 to PIC24F, remap legacy I/O names to RA/RB/RC ports and recalculate ADC acquisition delays.
Place the 32.768 kHz crystal close to the SOSCO/SOSCI pins with a ground guard ring for low-noise RTCC operation. Route ICSP signals (ICSCLK/ICSDAT) so they are accessible at the PCB edge for in-circuit debug. Recommended trace width 0.2 mm for signal integrity on this 5x5 mm QFN footprint.
Compliance-Informationen
RoHS and REACH compliance per Microchip product page; lead-free matte-tin finish confirmed by MQ package suffix. AEC-Q100 not qualified - use automotive-grade variants (e.g. PIC24F08KL302-I/MQ VAO) for AEC applications.
