PIC24FV32KA304-I/MV Présentation
A 16-bit MCU (microcontroller unit) is an embedded computing device that uses a 16-bit wide data path and instruction word to deliver higher code density, richer peripherals, and better computational throughput than 8-bit MCUs while consuming less power and costing less than 32-bit alternatives. The PIC24F family sits in Microchip's mid-range MCU portfolio, between the PIC16/PIC18 8-bit families and the PIC32 32-bit families, targeting general-purpose and low-power embedded applications.
Key features of the PIC24FV32KA304 include four 16-bit timers, two I2C, two SPI, two UART modules, a 12-bit A/D converter with up to 16 channels, and a Real-Time Clock and Calendar (RTCC) that operates during Deep Sleep. The 48-pin UQFN package provides compactness for space-constrained designs while exposing 36 general-purpose I/O pins. The integrated DMA controller and 16-bit wide data path accelerate data movement in signal-processing and control loops.
The device is built on a low-power CMOS process with multiple low-power modes including Doze, Idle, Sleep, and Deep Sleep, with the RTCC and select peripherals continuing to run in Deep Sleep for wake-up events. This enables sub-microamp standby current for battery-powered IoT endpoints and remote sensors, while the 32 MHz MIPS core provides the headroom for protocol stacks such as Modbus, BLE HCI, or LoRaWAN MAC layers.
Typical applications include IoT sensor nodes, wearable health monitors, battery-powered data loggers, low-power remote controls, home automation controllers, and industrial sensor interfaces. The wide-voltage support (2.0V to 5.5V) also enables direct connection to 3.3V and 5V mixed-voltage systems, simplifying analog front-end designs.
When designing with this part, ensure that the Decoupling capacitor is placed within 4 mm of VDD/AVDD pins, and that the UQFN exposed pad is properly soldered to the ground plane for thermal and electrical performance. Programming is supported by Microchip's MPLAB X IDE and XC16 compiler, with ICD debugging via standard 4-wire ICSP.

Applications typiques
PIC24FV32KA304-I/MV convient pour 6 applications: IoT Sensor Nodes and Edge Devices, Battery-Powered Wearable Health Monitors, Low-Power Remote Controls and HIDs, Industrial Sensor Interfaces and Data Loggers, Home Automation and Smart Home Controllers, Automotive Body Electronics and Accessories.
IoT Sensor Nodes and Edge Devices
The PIC24FV32KA304-I/MV fits IoT sensor nodes thanks to its nanoWatt XLP Deep Sleep current with RTCC wake-up and 2.0V-5.5V supply range that accepts coin cells and 3.3V system rails directly. The 32 KB Flash and 2 KB RAM run Bluetooth HCI, LoRaWAN MAC, or Zigbee stacks, while the 32 MHz MIPS core keeps protocol overhead low. Placing the MCU between the battery and sensor I/O with a 4.7uF decoupling cap minimizes sleep current and maximizes battery life.
Recommandé
Battery-Powered Wearable Health Monitors
The PIC24FV32KA304-I/MV suits wearable health monitors because its Deep Sleep current stays in the nanoamp range with RTCC still running, preserving multi-year battery life on a CR2032 coin cell. The 12-bit ADC with up to 16 channels reads multiple biometric sensors (heart rate, SpO2, temperature), and the 2.0V-5.5V range supports direct connection to lithium-polymer batteries. Designers route the analog AVDD pin through a ferrite bead to isolate sensor noise from the digital core.
Recommandé
Low-Power Remote Controls and HIDs
The PIC24FV32KA304-I/MV is well matched to remote controls and human interface devices because its wide supply range supports direct 3V coin-cell operation, while the two UART/SPI peripherals drive wireless transceivers like sub-GHz radios or BLE modules. The 36 GPIO pins handle key matrices, LED indicators, and haptic feedback without external expanders. Designers typically run the CPU at 1 MHz or less via the internal oscillator to keep active current below 1 mA.
Recommandé
Industrial Sensor Interfaces and Data Loggers
The PIC24FV32KA304-I/MV serves industrial sensor interfaces due to its 12-bit ADC accuracy, 5V-tolerant I/O, and RTCC with Deep Sleep wake-up for periodic sampling at multi-second intervals. The 32 KB Flash stores calibration constants and Modbus RTU protocol libraries, while 2 KB RAM buffers samples between transmission bursts. Pair with a 4-20 mA loop transmitter and isolated RS-485 transceiver for industrial PLC replacement designs.
Recommandé
Home Automation and Smart Home Controllers
The PIC24FV32KA304-I/MV integrates well into home automation hubs and sensor nodes because its dual I2C buses drive multiple sensor breakouts (temperature, humidity, light) simultaneously, while the SPI bus interfaces with wireless modules like LoRa or sub-GHz radios. The 32 MHz CPU runs local control loops and Zigbee or Thread border router routines without offloading to a host processor. Wide supply tolerance enables direct wall-wart or USB 5V input.
Recommandé
Automotive Body Electronics and Accessories
The PIC24FV32KA304-I/MV is suitable for non-safety automotive body electronics such as ambient lighting controllers, seat heaters, and accessory modules where its 5V-tolerant I/O interfaces directly with vehicle 12V-derived rails through external regulators. The wide industrial temperature range and 32 KB Flash support CAN-based body networks via external transceivers. For safety-critical systems, designers migrate to AEC-Q100-qualified PIC18 or dsPIC variants.

Principaux différenciateurs
- Wider operating voltage range (vs PIC24F32KA304-I/MV)
- Twice the Flash memory (vs PIC24FV16KA304-E/MV)
- Lower power consumption and nanoWatt XLP (vs PIC24FJ64GA702-I/MV)
- Identical industrial temperature range (vs PIC24FV32KA304-E/MV)
Notes de conception
Place a 10uF ceramic decoupling capacitor within 4 mm of each VDD/AVDD pin pair. Use separate analog and digital supply rails joined at a single point near the MCU's VCAP pin. Add a 1uF cap on VCAP to stabilize the internal core voltage regulator; bypassing this cap is a common source of oscillator drift and ADC reference noise.
Estimated: at 32 MHz full-speed operation with all peripherals active, the PIC24FV32KA304-I/MV draws approximately 15 mA, dissipating roughly 75 mW at 5V. The UQFN-48 package's exposed pad must be soldered to a continuous ground plane (at least 100 mm^2 of copper) to keep junction temperature rise below 30C above ambient at this dissipation level.
Route the crystal traces (OSC1, OSC2) with short, symmetric lengths and surround them with a ground guard ring to prevent coupling of digital switching noise into the oscillator. Keep ADC input traces away from PWM or high-speed digital traces; the 12-bit ADC is sensitive to ground bounce on the analog ground plane.
Do not omit the VCAP capacitor on pin 41 - the internal 1.8V regulator will not regulate without it, causing erratic behavior and brown-out resets. Ensure the MCLR pull-up resistor is 10 kohm to VDD; floating MCLR leads to spurious resets during power-up. The UQFN exposed pad MUST be soldered to ground - missing solder here causes thermal runaway and analog reference drift.
