PIC24FV16KA304-I/MV Overview
What is a microcontroller? A microcontroller (MCU) is a single-chip computer that contains a CPU core, program memory (Flash), data memory (RAM), non-volatile storage (EEPROM), and a range of peripherals such as analog-to-digital converters, timers, and communication interfaces. MCUs belong to the broader category of embedded processors, sitting below microprocessors in complexity but above discrete logic in integration. The PIC24F 'XLP' (eXtreme Low Power) family targets energy-constrained applications where quiescent current in nanoamps and active current in microamps per MHz are critical design parameters.
Key features of the PIC24FV16KA304 include a 12-bit ADC with up to 16 input channels, a Charge Time Measurement Unit (CTMU) for capacitive touch and precise time measurement, a Real-Time Clock and Calendar (RTCC) that operates in Deep Sleep mode, plus Deep Sleep Brown-Out Reset (DSBOR) and Deep Sleep Watchdog Timer (DSWDT). These Deep Sleep peripherals enable nanoamp-level standby currents while keeping essential housekeeping functions alive.
The device uses a 16-bit modified RISC instruction set with a 24-bit instruction word for code density, supports 17 general-purpose I/O, and provides peripheral interfaces including UART, SPI, and I²C. Its combination of low-power modes, integrated EEPROM, and the CTMU peripheral makes it a single-chip platform for sensor nodes, touch interfaces, and battery-powered instrumentation.
Typical applications include IoT sensor nodes running on coin-cell batteries, wearable medical monitoring devices, remote controls, low-power wireless sensor transmitters, and home automation end-points. The RTCC plus DSWDT architecture is also well suited to industrial data loggers that sleep for long intervals between measurements.
When designing with this MCU, size the decoupling network according to the ADC sampling rate and prefer sleep modes that retain the RTCC for wake-up scheduling; designers can compensate with external resistor inputs when the on-chip ADC dynamic range is insufficient.

Typical Applications
PIC24FV16KA304-I/MV is suitable for 6 applications: Battery-Powered IoT Sensor Node, Wearable Health Monitoring, Capacitive Touch User Interface, Industrial Data Logger, Remote Control / Wireless End-Node, Home Automation Sensor Hub.
Battery-Powered IoT Sensor Node
The PIC24FV16KA304-I/MV fits battery-powered IoT sensor nodes thanks to its 1.8V-3.6V supply range, deep-sleep currents in the nanoamp range, and on-chip RTCC that keeps time-stamping alive while the CPU sleeps. CTMU enables precise temperature or capacitance measurements. Typical 32 MHz active mode draws only a few mA; sleep current is well under 1 uA.
Recommended
Wearable Health Monitoring
For wearable health monitors, the PIC24FV16KA304-I/MV's XLP nanoamp Deep Sleep modes with RTCC wake-up extend coin-cell battery life to months or years. The 12-bit ADC supports bio-signal channels such as pulse oximetry or skin conductance, while the 2 KB RAM and 16 KB Flash are sufficient for simple on-device DSP and BLE control logic. The 6x6 mm UQFN package fits space-constrained wearables.
Recommended
Capacitive Touch User Interface
The on-chip CTMU (Charge Time Measurement Unit) makes the PIC24FV16KA304-I/MV ideal for capacitive touch buttons, sliders, and proximity sensors. It times capacitor charge/discharge cycles with picosecond resolution, enabling reliable touch detection through glass or plastic overlays. Combined with deep-sleep wake-on-touch, the design can idle below 1 uA between user interactions.
Recommended
Industrial Data Logger
Industrial data loggers benefit from the PIC24FV16KA304-I/MV's deep-sleep DSBOR and DSWDT peripherals that monitor system health while the CPU is off. The 512-byte EEPROM stores calibration and logging parameters without external memory, and 16 KB Flash supports several months of compressed log retention at low sampling rates. The wide-voltage FV supply tolerates industrial 3.3V rails directly.
Recommended
Remote Control / Wireless End-Node
For handheld remote controls and wireless end-nodes, the PIC24FV16KA304-I/MV's low 1.8V minimum supply lets it run directly from two AA alkaline cells, while deep-sleep with wake-on-GPIO preserves battery for years of standby. The CTMU can drive simple touch keys, and the 32 MHz core can host lightweight RF protocol stacks for sub-GHz or BLE control links.
Recommended
Home Automation Sensor Hub
In home automation hubs the PIC24FV16KA304-I/MV functions as a low-power sensor concentrator that wakes periodically to read temperature, humidity, or motion sensors via I2C/SPI, then returns to deep sleep. The on-chip RTCC schedules wake-ups precisely, and the CTMU can drive self-capacitive soil/moisture probes. Its 1.8V minimum supply is compatible with single-cell LiFePO4 chemistries.

Key Differentiators
- Lowest supply-voltage minimum in the 48-UQFN PIC24F XLP family (vs PIC24F16KA304-I/MV)
- Industrial-grade temperature coverage vs. extended-grade alternatives (vs PIC24FV16KA304-E/MV)
- Integrated CTMU for capacitive touch without external ICs (vs PIC24FJ64GA702-I/MV)
Design Notes
Decoupling: place 100 nF ceramic plus 1 uF to 10 uF bulk ceramic on each VDD pin, located within 3 mm of the pin. For the wide-voltage FV variant, ensure the supply never drops below 1.8 V during sleep-to-active transitions, or the POR may issue an unwanted reset. Estimated: with two VDD pins (33, 47) and one exposed pad, three 100 nF caps are minimum.
I/O configuration: many RA and RB pins share analog functions; clearing the corresponding ANS bit in firmware is required before using them as digital GPIO. Forgetting this step is a leading cause of 'dead pin' debugging. The CTMU requires explicit initialization of the current source before touch measurements; see the PIC24F family reference manual section 32 for the configuration sequence.
Exposed-pad thermal connection: the 48-UQFN has a center exposed pad (pin 46 listed as VSS) that must be soldered to a ground pad on the PCB with multiple thermal vias for proper heat dissipation and electrical grounding. Missing this connection can cause erratic resets and ADC inaccuracy. Route analog and digital grounds to a star point at the exposed pad.
ADC accuracy: the 12-bit ADC reaches full resolution only when the source impedance is below 5 kohm. For higher-impedance sensors, add an op-amp buffer such as MCP6001 close to the pin. Use a separate analog AVdd/AVss rail when available and decouple it from VDD with a ferrite bead to avoid digital switching noise coupling into ADC readings.
Compliance Information
RoHS compliant per Microchip product page. AEC-Q100 not applicable for I-grade; choose PIC24FV16KA304-E/MV for automotive.
