PIC24FV32KA304-E/MV 概要
A 16-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and peripherals on one die. Microcontrollers sit within the embedded-computing hierarchy: MCU -> microprocessor -> computer. The PIC24F family uses a 16-bit modified Harvard architecture with a rich instruction set, ideal for mixed-signal and low-power embedded designs requiring more performance than 8-bit MCUs but without the cost of 32-bit Cortex-M devices.
Key features include a 12-bit A/D converter with up to 16 input channels, multiple 16-bit timers, an RTCC with Deep Sleep operation, PWM/SCCP/MCCP modules, UART/SPI/I2C interfaces, a Charge Time Measurement Unit (CTMU), and the proprietary eXtreme Low Power (XLP) technology with Deep Sleep Brown-Out Reset (DSBOR) and Deep Sleep Watchdog Timer (DSWDT). These peripherals continue operating in Deep Sleep mode at currents measured in nanoamperes.
Architecturally, the device combines a 16-bit modified RISC core with a peripheral set optimized for low duty-cycle sensor applications. The 32 MHz MIPS performance enables real-time control loops while the XLP sleep modes (<100 nA typical) allow multi-year battery operation. CIP (Core Independent Peripherals) such as the CLC and 16-bit PWM reduce CPU overhead for deterministic mixed-signal tasks.
Typical applications include battery-powered sensor nodes, IoT edge devices, medical wearables, industrial remote monitoring, smart metering, automotive body electronics (non-safety), and Human-Machine Interface (HMI) controllers. The 48-UQFN package provides a compact footprint for space-constrained PCB designs.
When designing with this MCU, ensure the input voltage on Vdd stays within 2.0 V to 5.5 V and that decoupling capacitors are placed adjacent to all Vdd/Vss pairs. Configure unused pins as outputs to minimize power consumption, and use Deep Sleep mode aggressively for battery applications.

主な用途
PIC24FV32KA304-E/MV の用途: 6 件s: Battery-Powered IoT Sensor Nodes, Medical Wearable Devices, Industrial Remote Monitoring, Smart Energy Meters, Human-Machine Interface (HMI) Controllers, Automotive Body Electronics (Non-Safety).
Battery-Powered IoT Sensor Nodes
The PIC24FV32KA304-E/MV is well suited for battery-powered IoT sensor nodes because of its nanoWatt XLP technology and sub-100 nA Deep Sleep current consumption. With 32 KB Flash and 2 KB RAM, the MCU can run a small RTOS or state-machine protocol stack for LoRaWAN, Zigbee, or BLE beacon transmissions. The 12-bit ADC with up to 16 channels reads multiple analog sensors while the RTCC with Deep Sleep operation maintains accurate time-stamping without waking the CPU. The 2.0 V to 5.5 V wide Vdd range lets the design run directly from a single CR2032 (3 V) or two AA cells (3 V). The 48-UQFN 6x6 mm footprint minimizes PCB area, leaving more room for the battery.

Medical Wearable Devices
Wearable medical devices benefit from the PIC24FV32KA304-E/MV's low power consumption and high-performance 16-bit core. The 32 MHz / 16 MIPS throughput enables real-time processing of heart-rate, SpO2, or temperature sensor data while the 12-bit ADC captures analog front-end signals with sufficient resolution. The CTMU peripheral simplifies touch/proximity sensing used in user interfaces. The -40 C to +125 C extended temperature grade supports wearable applications exposed to body heat and outdoor environments. Microchip's MPLAB X IDE and XC16 compiler provide FDA-relevant design history documentation, and the XLP modes under 100 nA extend battery life to multi-month operation between charges in continuous-monitoring wearables.
おすすめ
Industrial Remote Monitoring
The PIC24FV32KA304-E/MV fits industrial remote monitoring stations that need wide temperature operation (-40 C to +125 C) and reliable sensor data acquisition. The DSBOR and DSWDT peripherals continue monitoring system health in Deep Sleep, ensuring the MCU recovers gracefully from brown-out events at unattended installations. The 16 ADC channels accept multiple analog inputs from 4-20 mA current loops or 0-10 V sensor signals through external resistor dividers. The wide 2.0 V to 5.5 V supply range allows direct connection to 24 V industrial bus through a simple buck regulator. The 32 KB Flash accommodates Modbus or proprietary protocol stacks with data logging to internal EEPROM.
おすすめ
Smart Energy Meters
Smart electricity and water meters benefit from the PIC24FV32KA304-E/MV's low-power operation, real-time clock, and robust peripheral set. The RTCC with Deep Sleep maintains accurate time-of-use billing timestamps at 32.768 kHz crystal accuracy while consuming microamps. The 16 ADC channels read voltage and current sensors from the metrology front-end, while the UART/SPI/I2C interfaces connect to wireless M-Bus, LoRa, or NB-IoT modems. The 32 KB Flash holds the metering algorithm, calibration constants, and communication protocol stacks. With XLP sleep currents under 100 nA, the design supports 10+ year battery life in remote AMR/AMI deployments, reducing operational costs for utilities.
おすすめ
Human-Machine Interface (HMI) Controllers
The PIC24FV32KA304-E/MV drives small HMI panels with up to 16 capacitive-touch buttons through the CTMU peripheral and 16-bit PWM outputs for LED dimming or LCD backlight control. The 16-bit core executes state machines for button debouncing, slider gestures, and LED animations at speeds sufficient for 100 Hz refresh without DMA. The 2 KB RAM buffers small display frames, and the 32 KB Flash stores multi-language UI strings, button mappings, and motor control profiles. SPI and I2C interfaces connect to external OLED or character LCDs. The wide 2.0 V to 5.5 V Vdd lets the HMI board run directly from 5 V industrial supplies or 3.3 V battery rails.
おすすめ
Automotive Body Electronics (Non-Safety)
The PIC24FV32KA304-E/MV's -40 C to +125 C extended temperature grade suits automotive body electronics applications such as interior lighting controllers, seat-position memories, mirror adjusters, and HVAC blend-door actuators. The 16-bit PWM modules drive DC motors and LED strings with fine resolution, while the 12-bit ADC reads potentiometer positions for accurate position feedback. The wide 2.0 V to 5.5 V input tolerates 12 V battery transients through external TVS protection and voltage regulators. The DSBOR and DSWDT ensure recovery from load-dump events. Note: this part is NOT AEC-Q100 qualified - for safety-critical ADAS or powertrain applications, choose AEC-Q100 qualified PIC24HJ or dsPIC33 devices.

設計ノート
Place a 0.1 uF ceramic decoupling capacitor adjacent to every Vdd/Vss pin pair and a single bulk 10 uF tantalum or ceramic capacitor near the MCU power pin. The wide 2.0 V to 5.5 V operating range allows direct operation from a CR2032 coin cell (3 V) for IoT sensor applications, but battery impedance rises as cells discharge - ensure firmware handles voltage droops during radio transmissions. For sub-100 nA Deep Sleep operation, all unused pins must be configured as digital outputs driving low to minimize pin leakage currents, per Microchip PIC24F XLP design guidelines.
The 48-pin UQFN (6x6 mm) package has an exposed thermal pad (EP) that MUST be soldered to a corresponding PCB copper pad for mechanical reliability and thermal dissipation. Connect the EP to the ground plane through at least 9 thermal vias (0.3 mm drill, 0.6 mm pitch) under the EP area. Route all analog signals (ADC inputs, Vref+, Vref-) away from high-frequency digital switching traces to minimize coupling. Use a continuous ground plane under the MCU body and avoid signal traces beneath the package.
Estimated: at maximum 32 MHz CPU clock with all peripherals enabled and 3.3 V supply, the MCU consumes approximately 18 mA active current, dissipating 60 mW. At 85 C ambient, junction temperature rise is roughly 6 C above ambient using the UQFN thermal resistance of approximately 100 C/W (per Microchip package datasheet). For applications near +125 C ambient, derate CPU duty cycle to 50% or use Sleep modes aggressively to maintain junction temperature within the 150 C maximum rating. Per the manufacturer datasheet, exact thermal resistance figures depend on PCB copper area and airflow.
Do not apply 5 V signals to digital I/O pins when Vdd is below 4.5 V - the GPIO absolute maximum ratings are Vss-0.3 V to Vdd+0.3 V. Always configure the Configuration bits (FOSC, FICD, FWDT) using MPLAB X IDE BEFORE programming Flash - incorrect Configuration bits can lock the device or prevent debugging. The RTCC requires a 32.768 kHz crystal on SOSCO/SOSCI pins with proper load capacitors (typically 4-7 pF) for accurate timekeeping. Per Microchip errata documentation, ignore any spurious ADC channel readings during the first ADC conversion after wake-up from Deep Sleep.
