PIC24F08KA101-I/SS 概要
An MCU (microcontroller unit) is a single-chip computer containing a CPU core, program and data memory, and programmable peripherals. The PIC24F belongs to Microchip's 16-bit modified-Harvard architecture family, sitting above the 8-bit PIC18 and below the 32-bit PIC32 in Microchip's MCU hierarchy. Within power-management IC taxonomy, MCUs are distinct from linear regulators and DC-DC converters but frequently pair with them as host controllers for sensor nodes, motor drivers, and human-machine interfaces. The XLP variants extend battery life through sub-microamp deep-sleep currents that competitor MCUs cannot match without external RTC chips.
Key features include 16 channels of 10-bit ADC, 4 timers, and communication peripherals (I2C, IrDA, SPI, UART/USART). The device operates from 1.8V to 3.6V across an industrial temperature range of -40C to +85C, supporting brown-out detect/reset and power-on reset for robust operation in noisy environments.
The PIC24F08KA101 uses a 16-bit modified-Harvard architecture with a 24-bit instruction word, providing 16 MIPS throughput at 32MHz. The integrated nanoWatt XLP technology enables run currents below 1 mA/MIPS and deep-sleep currents in the nanoamp range, with RTCC, DSBOR, and DSWDT operating even in deep sleep to maintain real-time functionality.
Typical applications include battery-powered sensor nodes, IoT edge devices, portable medical instruments, and remote controls. Its wide operating voltage and low power consumption also suit industrial 4-20 mA loop-powered transmitters and wearables.
When designing with this part, ensure the 20-pin SSOP footprint matches the SSOP land pattern on the PCB. Provide a 0.1 uF decoupling capacitor within 5 mm of each VDD pin, and place the bulk capacitor near the voltage regulator output to handle transient loads during deep-sleep wake events.

主な用途
PIC24F08KA101-I/SS の用途: 6 件s: Battery-Powered IoT Sensor Nodes, Portable Medical Instruments, Remote Controls and Consumer Wireless, Industrial 4-20 mA Loop-Powered Transmitters, Wearable Fitness and Health Trackers, Smart Home Sensor Hubs.
Battery-Powered IoT Sensor Nodes
The PIC24F08KA101-I/SS's nanoWatt XLP technology achieves deep-sleep currents below 100 nA with RTCC active, allowing coin-cell CR2032-powered sensor nodes to operate for years. The 16 MIPS throughput at 32MHz handles sensor sampling from the 10-bit ADC and UART command processing to an external BLE or LoRa module. The 1.8V minimum operating voltage lets the MCU run directly from a depleted 2xAA battery stack without boost converter overhead.
おすすめ
Portable Medical Instruments
The PIC24F08KA101-I/SS suits portable medical devices such as glucose meters, pulse oximeters, and digital thermometers due to its low-power operation and integrated EEPROM for storing calibration constants. The 8KB Flash holds firmware for sensor signal conditioning algorithms, while 1KB RAM is adequate for sample buffers. Wide 1.8-3.6V input allows direct Li-ion battery operation with no LDO dropout concerns at low charge states.
おすすめ
Remote Controls and Consumer Wireless
The PIC24F08KA101-I/SS paired with an external 2.4 GHz transceiver creates an ultra-low-power remote control with months-long battery life. Its deep-sleep mode with wake-on-I/O-change allows the MCU to sleep until a button press, drawing minimal current between transmissions. The 10-bit ADC and PWM outputs drive LED backlighting, while UART/SPI interfaces connect to RF modules like the Microchip MRF24XA or third-party BLE SoCs.
おすすめ
Industrial 4-20 mA Loop-Powered Transmitters
The PIC24F08KA101-I/SS operates directly from the 4-20 mA loop voltage after a small shunt regulator, eliminating the need for separate power conditioning circuits in field-mounted sensors. Its industrial -40C to +85C operating range handles outdoor and process-plant environments, while integrated 10-bit ADC digitizes sensor signals for HART or IO-Link communication. The 16 MIPS handles protocol stack layers without external ASIC.
おすすめ
Wearable Fitness and Health Trackers
The PIC24F08KA101-I/SS's XLP nanoWatt deep-sleep mode extends wearable battery life by allowing the MCU to sleep between heart-rate measurements while RTCC maintains accurate timekeeping. The integrated EEPROM stores user profile data, and the small 20-SSOP package fits wristband form factors. The 10-bit ADC reads PPG (photoplethysmography) signals from optical sensors with sufficient resolution for step counting and heart-rate algorithms.
おすすめ
Smart Home Sensor Hubs
The PIC24F08KA101-I/SS serves as a low-power edge node in smart home systems, aggregating multiple I2C sensors (temperature, humidity, motion) and forwarding data over Wi-Fi via a co-processor. Its deep-sleep mode allows the hub to sleep until motion or environmental thresholds trigger a wake event. The 8KB Flash holds custom protocol firmware, and 16 GPIO support multiple sensor connections.

設計ノート
Estimated: at 32MHz and 3.3V VDD, active current is approximately 8 mA. Switching to 1 MHz internal oscillator drops active current to ~250 uA. For battery life maximization, use Sleep mode with RTCC active (~500 nA) and wake only on external interrupts. Place a 0.1 uF decoupling capacitor within 5 mm of each VDD pin (pins 8, 19 are VSS; pin 20 is VDD on this package) to suppress switching transients.
Route the ICSP clock (PGC, pin 17) and data (PGD, pin 18) traces away from high-frequency switching nodes and keep them under 50 mm to maintain reliable in-circuit programming. The MCLR pin (pin 1) requires a 10 kohm pull-up to VDD and a 100 nF capacitor to ground for proper reset behavior. Keep analog inputs (AN0-AN3) traces short and away from digital switching lines to minimize ADC noise coupling.
Do not exceed the absolute maximum VDD of 4.0V or damage will occur. The 10-bit ADC requires the bandgap reference to be stable for at least 20 us before conversion starts. When migrating firmware from PIC24F08KA101 to PIC24F04KA201, verify that code size does not exceed 4KB or Flash write errors will occur. The configuration bits must be set correctly for the oscillator mode or the device will not start.
