PIC24F08KL301-I/P 概要
A 16-bit microcontroller (MCU) is a microprocessor that executes instructions 16 bits at a time, delivering significantly higher code density and arithmetic throughput than 8-bit parts while remaining cheaper and lower-power than 32-bit Cortex-M devices. Within Microchip's portfolio, the PIC24F family sits between the PIC18 (8-bit) and dsPIC33/PIC32 (32-bit) families. The KL301 sub-family adds nanoWatt XLP extreme-low-power peripherals such as deep-sleep, RTC, and Windowed Watchdog Timer (WWDT) that allow typical sleep currents below 1 µA, making it a hybrid category of low-power MCU and ultra-low-power MCU positioned for battery-backed designs.
Key features include 12-bit ADC with up to 12 channels, two 8-bit timers plus one 16-bit timer, an enhanced CCP (ECCP) module, MSSP for both I²C and SPI, an UART, two analog comparators, a charge time measurement unit (CTMU), and a peripheral pin select (PPS) engine for flexible signal routing. The device supports up to three 16-bit PWM channels with ECCP and is offered in industrial (-40°C to +85°C) operating temperature.
The KL301 is built on an enhanced Harvard architecture with a 16-bit data path, hardware multiply, and a 32MHz instruction cycle. Its nanoWatt XLP technology combines Sleep, Deep Sleep, and Idle modes with peripheral clock scaling to deliver quiescent currents suitable for coin-cell and energy-harvesting applications, while the MSSP + CCP combination allows simple migration paths from PIC18 designs.
Typical applications include battery-powered sensor nodes, IoT edge devices, smart thermostats, low-power remote controls, wearables, and cost-sensitive industrial controllers that benefit from familiar PIC toolchains and the MPLAB X IDE ecosystem.
When designing with the KL301, choose LDO regulators (not switching) for the analog supply to preserve ADC accuracy, and provide adequate bulk decoupling of 1µF plus 0.1µF near the VDD pin. Ensure the ICSP™/ICD programming pins (PGECx/PGEDx) are accessible on the PCB.

主な用途
PIC24F08KL301-I/P の用途: 6 件s: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Smart Thermostat / HVAC Controller, Industrial Sensor / 4-20mA Transmitter, Wearable Fitness / Health Monitor, Low-Cost Industrial Control / Relay Driver.
Battery-Powered IoT Sensor Node
The PIC24F08KL301-I/P is a strong fit for battery-powered IoT sensor nodes thanks to its nanoWatt XLP deep-sleep current below 1 µA and 8KB Flash running at up to 32MHz. The device wakes periodically, samples sensors via the 12-bit ADC and CTMU, transmits over a UART- or SPI-attached radio, and returns to deep sleep - extending coin-cell life to multiple years. The 1KB SRAM and 256 bytes of flash-emulated EEPROM are sufficient for sensor calibration constants and rolling buffers. Same-family pin compatibility with PIC24F08KL201-I/P enables effortless capacity scaling.
おすすめ
Capacitive Touch User Interface
The PIC24F08KL301-I/P integrates Microchip's CTMU (Charge Time Measurement Unit) which enables reliable capacitive touch sensing without an external touch controller, reducing BOM cost in appliances and consumer UI panels. Combined with 17 I/O pins, PPS routing, and the ECCP for PWM-driven backlight dimming, the part can drive a complete touch-and-display control board in a 20-pin through-hole footprint. nanoWatt XLP idle currents below 1 µA preserve standby battery life in wall-switch and remote-control applications.
おすすめ
Smart Thermostat / HVAC Controller
In smart thermostat and HVAC controllers the PIC24F08KL301-I/P delivers 32MHz performance to run control loops, drive a small graphical LCD via SPI, and communicate over UART/Wi-Fi. The 8KB Flash fits a PID loop, scheduling logic, and a Modbus/thermostat protocol stack. The MSSP peripheral provides SPI for the display and I2C for sensors. Wide 1.8-3.6V operation supports both battery and 24VAC-derived rails, and the nanoWatt XLP sleep modes keep idle power low when the backlight turns off.
おすすめ
Industrial Sensor / 4-20mA Transmitter
The PIC24F08KL301-I/P serves as a low-power MCU for 4-20mA loop-powered sensor transmitters and industrial sensor interfaces. Its 12-bit ADC at 200 ksps provides sufficient resolution for pressure, level, and flow sensors, while the 32MHz core runs linearization math for RTDs and thermocouples. The MSSP drives an SPI DAC for the loop output, and nanoWatt XLP keeps the transmitter within strict loop-power budgets. The 20-pin PDIP package simplifies hand-soldering during prototyping and field service.
おすすめ
Wearable Fitness / Health Monitor
Wearables and fitness bands benefit from the PIC24F08KL301-I/P's nanoWatt XLP deep-sleep current below 1 µA combined with 32MHz burst performance for signal processing. The CTMU can be repurposed for body-impedance measurement, and the 12-bit ADC reads pulse-oximeter or accelerometer signals. UART/BLE modules attach via MSSP/UART for phone sync. The industrial -40C to +85C operating range tolerates body-heat and cold-weather scenarios, while 8KB Flash fits a step-counter, sleep tracker, and BLE GATT client.
おすすめ
Low-Cost Industrial Control / Relay Driver
In factory automation modules, the PIC24F08KL301-I/P provides a reliable 16-bit MCU core with the MSSP for I2C sensor expansion, UART for RS-485 links (via external transceiver), and ECCP for PWM-driven relays or solid-state switches. The 20-pin PDIP format is preferred for hand-rework in the field, while the nanoWatt XLP modes keep quiescent power low in always-on control cabinets. The industrial -40C to +85C temperature grade suits most factory environments.

設計ノート
Place a 1 µF ceramic + 0.1 µF ceramic decoupling pair as close as possible to the VDD pin (pin 20) of the PIC24F08KL301-I/P; add a second 0.1 µF on the AV analog rail to preserve 12-bit ADC noise performance. Use an LDO (not a switching regulator) for the MCU rail to keep ripple below 1 mVpp. For deep-sleep operation, ensure any unused I/O pins are set to outputs and driven low to eliminate floating-input leakage that can raise deep-sleep current above 1 µA.
Keep the ICSP programming/debug pins (PGECx / PGEDx) accessible on the PCB edge or test pads so the ICD can attach without removing the chip. Maintain a 100-mil keep-out around the 20-pin PDIP footprint for hand-soldering and rework. Route the MCLR line with a 10 kΩ pull-up to VDD and a 100 nF cap to ground to filter noise; avoid long MCLR traces which can couple reset glitches.
The 12-bit ADC at 200 ksps requires source impedance below 5 kΩ for full accuracy. Add a 1 nF C_foil cap + 100 Ω series resistor on each analog input if your sensor source impedance exceeds this. Decouple the VREF+/VREF- pair locally with 1 µF and 0.1 µF caps when using external ADC reference. Average 16 samples in software to further improve SNR by 12 dB.
Do not enable the 4x PLL with an FRC source below 4 MHz - the PLL requires a minimum input frequency per the datasheet and the device will fail to lock. Do not exceed 3.6 V on any pin - the KL301 is a 3.3 V part and 5 V tolerance is not guaranteed. Do not rely on the internal 8 MHz FRC without checking the calibration word if your UART baud rate is timing-critical.
