PIC24FV32KA302-I/SO 개요
A PIC24F microcontroller is a 16-bit RISC-based MCU from Microchip's PIC family that targets low-power and battery-constrained embedded applications. The "FV" prefix denotes the wide voltage operating range (2.0V-5.5V), the "32K" denotes 32 KB program Flash, the "A302" denotes the specific peripheral mix, and the "I/SO" suffix specifies the industrial temperature grade (-40C to +85C) in a 28-pin Small Outline IC package. PIC24F sits in the hierarchy PIC MCU -> 16-bit MCU -> low-power MCU -> embedded MCU.
Key features include a 12-bit ADC with up to 16 input channels, 5 CCP/SCCP modules, a charge time measurement unit (CTMU), real-time clock and calendar (RTCC), deep-sleep brown-out reset (DSBOR), deep-sleep watchdog timer (DSWDT), and multiple serial interfaces (UART, SPI, I2C). XLP technology with sleep currents down to 20 nA (typical) makes the part ideal for battery-powered and energy-harvesting designs. The 28-SOIC wide-body package provides 17 general-purpose I/O pins with peripheral pin select (PPS) routing flexibility.
The PIC24FV32KA302 uses a modified Harvard architecture with a 16-bit data path, 24-bit instruction word, and a hardware multiplier/DMA engine. The instruction set is highly orthogonal, and C-compiler friendly through MPLAB XC16. On-chip peripherals are mapped through the peripheral pin select (PPS) module, allowing flexible assignment of digital functions to physical pins. The integrated CTMU enables capacitive touch sensing and precision time measurement with sub-microsecond resolution.
Typical applications include low-power IoT sensor nodes, battery-operated handheld instruments, capacitive touch user interfaces, medical glucose meters and portable diagnostic devices, home automation controllers, and energy-harvesting wireless sensor platforms. The wide 2.0V-5.5V supply range allows direct operation from a single Li-ion cell, two AA cells, or a 5V regulated rail.
When designing with this device, enable the on-chip DSBOR and DSWDT for reliable deep-sleep wake-up behavior. Use the PPS module to remap peripherals to available pins, and place a 100 nF decoupling capacitor as close as possible to each VDD/VBAT pin pair. MPLAB X IDE with the free MPLAB XC16 compiler provides the standard toolchain.

일반적인 애플리케이션
PIC24FV32KA302-I/SO 적합 용도: 8 애플리케이션s: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Portable Medical Diagnostic Device, Home Automation Controller, Industrial Sensor Transmitter (4-20mA / 0-10V), Energy-Harvesting Wireless Sensor, Automotive Body Control Module, Smart Meter Data Logger.
Battery-Powered IoT Sensor Node
The PIC24FV32KA302-I/SO is well-suited for battery-powered IoT sensor nodes thanks to its 20 nA typical deep-sleep current with RTCC/DSBOR/DSWDT active, allowing multi-year battery life on a single coin cell. The wide 2.0V-5.5V operating range lets it connect directly to a 3V CR2032, two AA cells in series, or a 3.7V Li-ion cell without a voltage regulator. The CTMU enables capacitive soil-moisture or water-level sensing, while the 12-bit ADC with 16 channels reads temperature, humidity, and battery voltage. The 32 KB program memory stores the wireless protocol stack (e.g., LoRaWAN or Zigbee) plus sensor application code, and 2 KB RAM handles packet buffering. Design tip: enable the on-chip DSWDT with a 4-second timeout to recover from deep-sleep lockup conditions automatically.

Capacitive Touch User Interface
The integrated CTMU and 12-bit ADC allow the PIC24FV32KA302-I/SO to implement up to 16 capacitive touch buttons, sliders, or proximity sensors without an external touch controller. The PPS peripheral pin select module remaps the ADC and timer inputs to any available GPIO, simplifying PCB layout. The XLP nanoamp deep-sleep currents keep the touch wake-up power budget below 1 uA average, allowing always-on touch operation on battery-powered remote controls, white-goods HMIs, and industrial control panels. Microchip's AN1375 describes CTMU firmware implementation in detail. Trade-off: CTMU touch measurement requires calibrated baseline acquisition and environmental compensation for humidity/temperature drift.

Portable Medical Diagnostic Device
Medical devices such as glucose meters, pulse oximeters, and INR testers benefit from the PIC24FV32KA302-I/SO's combination of 16 MIPS CPU throughput for signal analysis, 32 KB Flash for algorithm storage, 2 KB RAM for sample buffers, and ultra-low deep-sleep current for battery life. The 12-bit ADC with 16 channels reads multiple sensor inputs simultaneously. The 2.0V-5.5V range allows direct operation from two AAA cells. The integrated RTCC provides accurate timestamp for medical data logging. Industrial temperature grade supports portable use across varied environments. Estimated: at 25 MHz operation with periodic sensor sampling, average current is below 500 uA, enabling 1+ year life on 2x AA cells.

Home Automation Controller
The PIC24FV32KA302-I/SO handles home automation hub duties including sensor reading (temperature, motion, door/window), actuator control (relays, dimmers), and serial communication to wireless modules. The peripheral mix - 5 CCP/SCCP modules for PWM dimming, UART/SPI/I2C for module interfacing, and PPS for flexible pin mapping - addresses most hub functions. The 32 KB Flash stores application code plus Zigbee/Z-Wave/Wi-Fi command handlers. The wide voltage range enables direct drive from 5V USB or 3.3V regulated rails. Design consideration: deep-sleep wake-up time from 20 nA mode is around 1 ms, which is acceptable for non-realtime sensors but requires external interrupt for time-critical events.

Industrial Sensor Transmitter (4-20mA / 0-10V)
Industrial 4-20mA or 0-10V analog output sensor transmitters require a microcontroller with high-resolution ADC, stable RTCC, and industrial temperature grade - all provided by the PIC24FV32KA302-I/SO. The 12-bit ADC reads pressure, flow, or level sensors with 0.024% resolution; PWM + output filter generates a 0-10V analog output; CCP modules drive H-bridges or DAC stages for 4-20mA current loops. The wide 2.0V-5.5V range and industrial -40C to +85C temperature grade handle harsh industrial environments. The 32 KB Flash stores linearization tables and HART or Modbus protocol stacks for smart transmitters.

Energy-Harvesting Wireless Sensor
Energy-harvesting wireless sensor platforms (solar, vibration, thermal) require sub-microamp deep-sleep currents to operate from harvested energy budgets. The PIC24FV32KA302-I/SO's 20 nA deep-sleep with RTCC/DSWDT active makes it ideal for these applications. The CTMU can wake the MCU on environmental change (capacitive sensing), and the 12-bit ADC reads the harvested energy storage voltage. The 2.0V-5.5V range allows direct connection to supercapacitor banks of 0.5F-10F. Trade-off: at 16 MIPS the CPU draws ~10 mA, so duty-cycling must keep active time below 1% to stay within harvested energy budgets.

Automotive Body Control Module
Body control modules (BCM) for non-safety automotive subsystems such as interior lighting, mirror control, and seat position memory can use the PIC24FV32KA302-E/SO (extended temperature variant). The 32 KB Flash stores control logic, 5 CCP modules generate PWM for LED dimming and motor speed control, and the 12-bit ADC reads position feedback. Note: this part is not AEC-Q100 qualified, so for safety-critical automotive subsystems (airbag, ABS, ADAS) choose a different PIC24 or dsPIC family with AEC-Q100 qualification. The wide 2.0V-5.5V supply range handles automotive 12V-battery transients when paired with external voltage regulation.
추천
Smart Meter Data Logger
Smart electricity, water, or gas meters benefit from the PIC24FV32KA302-I/SO's RTCC for accurate timestamping of consumption data, 32 KB Flash for storing several days of metering logs, 2 KB RAM for sample buffering, and 20 nA deep-sleep to extend battery life in battery-backed meters. The 12-bit ADC measures consumption signals from current transformers or pulse sensors, while UART or SPI interfaces connect to wireless M-Bus or LoRa modules for remote reading. The 2.0V-5.5V range allows direct connection to battery or supercapacitor backup power, and the 512-byte EEPROM stores calibration constants and meter ID over the product lifetime.

설계 노트
Estimated: At 32 MHz full-speed operation, the PIC24FV32KA302-I/SO draws approximately 10 mA active current. For battery-powered designs, duty-cycle the MCU so that active time stays below 1% of the period to fit within a 50-100 uA average budget. The deep-sleep mode with RTCC+DSWDT active achieves 20 nA typical, allowing multi-year battery life on a 220 mAh CR2032 cell if average current is kept below 5 uA. Always enable DSBOR and DSWDT in deep-sleep applications to recover from power-fault or firmware lockup conditions automatically.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 13) and the VSS pin (pin 8 or 28). For noisy supply rails (e.g., switching regulator driven), add a 10 uF bulk capacitor near the IC. Keep the crystal traces (OSC1/OSC2) short and symmetric, and route them away from high-speed digital signals. The exposed thermal pad is not present on the 28-SOIC, so no thermal pad soldering is required - this simplifies PCB layout compared to QFN packages.
Use the Peripheral Pin Select (PPS) module to remap digital peripherals (UART, SPI, I2C, PWM) to any available digital GPIO. This allows PCB routing optimization independent of firmware pin assignments. Note that analog functions (ANx inputs, VREF+/-, CTMU) are pin-fixed and cannot be remapped. For CTMU capacitive touch, dedicate quiet ground and shield the touch electrodes with a grounded trace to reduce false triggers from external noise.
Common pitfall: forgetting to configure the PPS module lock mechanism. The PPSUnlock macro sequence must be executed before re-assigning pins, otherwise the writes are silently ignored. Another pitfall: enabling ADC on shared analog pins without disabling digital input on those pins - this causes ADC reading instability due to digital input buffer cross-conduction. Use the AD1PCFGL register to configure each analog-capable pin as analog before enabling ADC sampling. Estimated: firmware developers typically require 2-3 hours for first-time PPS configuration.
When using the 28-SOIC wide-body package at 16 MIPS, signal integrity on high-speed digital lines (e.g., SPI at >10 MHz) is generally not an issue due to the moderate edge rates (5 ns typical). However, the CTMU and ADC analog inputs are sensitive to digital switching noise on adjacent pins. Place analog traces away from switching digital signals, and use a ground guard ring around sensitive analog sections. For applications requiring >40 dB ADC SNR, add an RC anti-aliasing filter at each ADC input (typically 1 kΩ + 100 pF for 1.6 kHz bandwidth).
