PIC24F08KA102-E/SP 概要
A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (typically Flash), data RAM, and a rich set of on-chip peripherals such as timers, ADC, communication interfaces, and general-purpose I/O on a single die. In the embedded hierarchy, microcontrollers sit alongside microprocessors inside the broader category of microcontrollers and embedded processors, which themselves are part of the larger semiconductor / integrated circuit (IC) family. Within Microchip's portfolio, the PIC24F family occupies the 16-bit segment between the 8-bit PIC16/PIC18 architectures and the 32-bit PIC32MX/PIC32MM families, offering a balance of deterministic performance, low power, and peripheral integration.
Key features of the PIC24F08KA102-E/SP include nanoWatt XLP deep-sleep modes with DSBOR (deep-sleep brown-out reset) and DSWDT (deep-sleep watchdog timer) that drop quiescent current into the sub-microamp range, a Real-Time Clock and Calendar (RTCC) that can operate during deep sleep, an internal oscillator that eliminates external clock components, and a wide operating voltage range suitable for 2-cell AA or single-cell Li-ion battery chemistries. The 28-pin SPDIP footprint offers generous I/O count for human-interface or sensor-conditioning designs.
Typical applications include wearable fitness/health monitors, remote control key fobs, battery-powered sensor nodes, smart thermostats, low-power IoT endpoints, and industrial data loggers. Engineers should note that the PIC24F08KA102-E/SP operates over the -40C to +125C industrial temperature range (the "E" temperature designator), making it suitable for harsh-environment deployments.

主な用途
PIC24F08KA102-E/SP の用途: 6 件s: Wearable Fitness & Health Monitors, Battery-Powered Remote Sensor Nodes, Remote Control Key Fobs & RF Tags, Smart Thermostats & HVAC Controllers, Low-Power IoT Data Acquisition Edge Nodes, Industrial Data Loggers.
Wearable Fitness & Health Monitors
The PIC24F08KA102-E/SP's nanoWatt XLP deep-sleep modes (DSBOR, DSWDT) drop quiescent current to sub-microamp levels while the RTCC keeps accurate timekeeping, enabling multi-month battery life on a coin cell. Its 32 MHz performance and 1.5 KB RAM handle heart-rate sampling, step counting, and BLE companion-control algorithms. The 28-SPDIP package is breadboard-friendly for prototype wearable PCBs.
おすすめ
Battery-Powered Remote Sensor Nodes
Industrial sensor hubs require wireless-friendly sleep currents, reliable wake-up, and deterministic ADC sampling. The PIC24F08KA102-E/SP delivers 9-channel 10-bit ADC for analog sensor arrays (temperature, humidity, gas) and SPI/I2C for digital sensors, all while consuming microamps in deep sleep. The -40C to +125C E temperature grade supports outdoor and factory-floor deployment without thermal derating.
おすすめ
Remote Control Key Fobs & RF Tags
RF key fobs spend 99% of their life in deep sleep and only wake on a button interrupt to transmit. The PIC24F08KA102-E/SP's DSBOR/DSWDT retention and sub-microamp deep sleep directly enable multi-year battery life on a CR2032. The integrated UART/SPI interfaces easily drive sub-GHz transceivers such as the Microchip MRF89XA for proprietary 868/915 MHz remote-control protocols.
おすすめ
Smart Thermostats & HVAC Controllers
Wall-mounted smart thermostats combine temperature/humidity sensing, LCD/button interfaces, and low-power wireless connectivity. The PIC24F08KA102-E/SP's 9-channel 10-bit ADC handles multiple analog sensors (NTC thermistor, humidity, light) while the 18 I/O drive keypads, relays, and triac interfaces. The RTCC supports time-based scheduling with deep-sleep retention, minimizing idle power.
おすすめ
Low-Power IoT Data Acquisition Edge Nodes
Edge IoT nodes aggregate sensor data, perform local filtering, and transmit via Wi-Fi/BLE/LoRa. The PIC24F08KA102-E/SP's 16 MIPS at 32 MHz handles basic DSP (moving-average, peak detection) before TX, and its deep-sleep modes allow scheduled-sampling at sub-Hz rates. The SPI interface connects directly to wireless modules; the I2C bus drives EEPROM datalogging for offline buffering.
おすすめ
Industrial Data Loggers
Stand-alone data loggers record process variables (vibration, pressure, current) over weeks or months without maintenance. The PIC24F08KA102-E/SP's 8 KB Flash stores firmware, 1.5 KB RAM buffers samples, and 512 B EEPROM retains calibration tables through battery swaps. The -40C to +125C E grade handles unheated enclosures, and the internal oscillator eliminates crystal-replacement failures.

設計ノート
Estimated: total power budget for a coin-cell design. With the PIC24F08KA102-E/SP in deep sleep at 20 nA (DSBOR+DSWDT active) versus 8 mA/MIPS active, a 220 mAh CR2032 coin cell lasts ~10 years if the MCU sleeps 99.9% of the time and wakes for 10 ms per second. Always consult the datasheet's nanoWatt XLP section for the actual current under your specific deep-sleep configuration.
Place a 100 nF decoupling capacitor as close as possible to VDD (pin 20) and a separate 100 nF on AVDD (pin 19). For analog sensor accuracy, add a 10 uF bulk capacitor on VDD and route AVSS as a Kelvin connection to VSS to avoid ground-bounce noise coupling into the ADC. Keep analog traces (AN0-AN6) away from switching nodes such as oscillator traces.
When migrating from PIC24F08KA102-E/SP to a lower-memory variant such as PIC24F04KA201-I/P, verify that your compiled code fits in 4 KB Flash - the linker will silently overflow otherwise. Also, on first prototypes confirm the MCLR pull-up resistor value (typically 10 kOhm to VDD) - a missing MCLR pull-up causes erratic resets when the ICSP programmer is disconnected. The internal oscillator typically provides +/-2% accuracy; use RTCC calibration or an external crystal if UART accuracy matters.
