PIC24FV16KA302-I/SP Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and programmable peripherals into one package. Microcontrollers in the PIC24F class are 16-bit modified-Harvard RISC architectures from Microchip Technology, sitting above 8-bit PIC10/12/16 MCUs and below 32-bit PIC32 devices in the company's product hierarchy. Within the PIC24F family, the FV16KA3xx sub-series is positioned for ultra-low-power general-purpose applications, competing with low-power ARM Cortex-M0+ MCUs from STMicroelectronics, NXP, and Renesas in the eXtreme Low Power (XLP) tier.
Distinguishing features of this part include 17 general-purpose I/O pins, integrated 12-bit ADC with up to 16 input channels, 5-bit DAC, multiple timers (Timer1, Timer2/3, RTCC), I2C, SPI, UART peripherals, and CTMU for capacitive touch sensing. The 'FV' prefix confirms a wide VDD range of 2.0 V to 5.5 V, supporting both 3.3V and 5V system rails, while the 'I' suffix denotes the -40C to +85C industrial temperature grade.
Typical applications include portable medical devices, IoT sensor nodes, wearable fitness bands, industrial sensor hubs, and battery-powered wireless accessories where Deep Sleep currents in the order of 20-50 nA extend coin-cell battery life to multiple years. When designing with this part, place the ICSP programming header footprint on the board even in production designs - this allows in-field firmware updates without desoldering the MCU.

Applications typiques
PIC24FV16KA302-I/SP convient pour 7 applications: Battery-Powered IoT Sensor Node, Portable Medical / Wearable Device, Industrial Sensor Hub / Data Logger, Capacitive Touch User Interface, USB HID Consumer Device, Smart Home Sensor / Building Automation, Automotive Aftermarket Accessory.
Battery-Powered IoT Sensor Node
The PIC24FV16KA302-I/SP fits battery-powered IoT sensor nodes because of its eXtreme Low Power (XLP) Deep Sleep current measured in tens of nanoamperes and its 12-bit ADC with 16 inputs for connecting multiple analog sensors. Placed on a 2-layer PCB with the MCU in Deep Sleep most of the time and waking periodically via the RTCC alarm or Watchdog Timer, a coin-cell CR2032 battery can power the node for 3-5 years at a 1% duty cycle. The 2.0 V to 5.5 V VDD range supports both primary Li-ion (3.7 V) and 2xAA (3.0 V) battery stacks without external regulators.
Recommandé
Portable Medical / Wearable Device
The PIC24FV16KA302-I/SP fits portable medical devices such as glucose meters, pulse oximeters, and wearable fitness bands because its low-power architecture and 12-bit ADC enable accurate biosignal acquisition with minimal battery drain. The CTMU peripheral supports capacitive touch electrodes for user input without mechanical buttons, reducing BOM and improving water-sealing. With 16 KB Flash and 2 KB SRAM, the device runs lightweight DSP filtering for heart-rate or SpO2 algorithms while keeping total system cost low.
Recommandé
Industrial Sensor Hub / Data Logger
The PIC24FV16KA302-I/SP fits industrial sensor hubs and remote data loggers because its 2.0-5.5 V supply range handles 24 V industrial bus power through a small LDO, while the 17 GPIO and 12-bit ADC accommodate multi-channel analog sensor arrays. The 16 KB Flash stores compressed log records and calibration constants; the 512-byte EEPROM retains configuration across power cycles. Hardware peripherals including UART, SPI, and I2C enable interfacing to industrial sensors (4-20 mA loops, Modbus RTU transceivers) for predictive maintenance and SCADA telemetry.
Recommandé
Capacitive Touch User Interface
The PIC24FV16KA302-I/SP fits capacitive touch user interfaces because its integrated CTMU (Charge Time Measurement Unit) measures capacitance on multiple GPIO pins without external touch controller ICs. With 17 GPIO available on the 28-SPDIP, designers can build 8-12 button keypads, slider controls, or proximity sensors for appliances, smart locks, and consumer products. The XLP Deep Sleep mode keeps idle touch-scan current in single-digit microamperes while still detecting user wake events.
Recommandé
USB HID Consumer Device
The PIC24FV16KA302-I/SP fits USB HID consumer devices such as keyboards, mice, presenters, and game controllers because its 32 MHz CPU and 16 MIPS throughput handle USB HID report generation, debouncing, and LED control without external MCU. While the part lacks native USB, a software-only USB 1.1 low-speed stack can run on the PIC24F at 16 MIPS for HID-class devices. The wide 2.0-5.5 V VDD range tolerates the 5 V USB VBUS rail directly without level shifting.
Recommandé
Smart Home Sensor / Building Automation
The PIC24FV16KA302-I/SP fits smart home sensors including temperature/humidity transmitters, leak detectors, and HVAC controllers because its eXtreme Low Power architecture supports battery or energy-harvesting power sources. The I2C/SPI/UART peripherals connect to wireless modules (LoRa, Sub-GHz RF, Wi-Fi co-processors) for cloud connectivity, while the 12-bit ADC digitizes thermistor, humidity, and gas-sensor analog outputs. The 28-SPDIP package suits through-hole designs in DIN-rail enclosures.
Recommandé
Automotive Aftermarket Accessory
The PIC24FV16KA302-I/SP fits automotive aftermarket accessories such as GPS trackers, OBD-II dongles, and tire-pressure monitor sensors because its 2.0-5.5 V supply range and -40C to +85C industrial temperature grade tolerate automotive 12 V rails through a regulator. For OEM automotive designs that require AEC-Q100, Microchip offers qualified PIC24 variants - the PIC24FV16KA302-I/SP is appropriate for non-safety aftermarket use cases only.

Notes de conception
The PIC24FV16KA302-I/SP supports 2.0 V to 5.5 V on the main VDD pin and requires an external 1 uF to 10 uF low-ESR ceramic capacitor on the VCAP pin (pin 20 on 28-SPDIP) to stabilize the internal core voltage regulator. Place this VCAP capacitor as close as physically possible to the pin with a short, wide trace to VSS; excessive trace inductance can cause core-voltage ripple and erratic behavior at 32 MHz operation.
Route the ICSP signals (PGECx/PGEDx on RB1/RB0 by default, or alternate remap pins) to an in-circuit programming header even in production designs. Use a 0.1 uF decoupling capacitor on each VDD pin (multiple VDD pins are present on the 28-SPDIP) located within 5 mm of the pin, plus a bulk 10 uF tantalum or ceramic capacitor at the board entry point. Keep the MCLR trace short and add a 10 kΩ pull-up and a transient-voltage-suppression diode if the design operates near inductive loads.
Do not confuse the I-suffix (industrial -40C to +85C) with the E-suffix (extended -40C to +125C) or the V-suffix (extended voltage). The 'V' in PIC24FV denotes wide-voltage 2.0 V to 5.5 V - PIC24F non-V variants are limited to 1.8 V to 3.6 V and will fail at 5 V. Also remember to configure unused I/O pins as outputs (not inputs) to minimize supply current in Deep Sleep mode; floating inputs can leak several microamperes each, defeating the XLP low-power advantage.
When using the analog inputs for ADC measurements, dedicate AVSS/AVDD to a quiet ground/power island separated from digital switching currents. Use the AVDD pin (if present in the chosen package variant) to power the analog supply domain. Keep analog traces short and shielded by ground pours; route digital switching signals (PWM, timers) away from sensitive analog traces to preserve 12-bit ADC SNR at full 32 MHz CPU operation.
