PIC24FV16KA301-E/P Overview
A 16-bit microcontroller (MCU) is a programmable integrated circuit that uses a 16-bit data path and instruction word, sitting between 8-bit MCUs (lower cost, simpler peripherals) and 32-bit MCUs (higher performance, larger address space). The PIC24F family specifically targets ultra-low-power applications, with XLP technology enabling nanoWatt deep-sleep modes. PIC24F MCUs are widely used in battery-powered, energy-harvesting, and always-on sensor applications where both computational throughput and quiescent current matter.
Key features of the PIC24FV16KA301 include integrated peripherals such as a 12-bit ADC (up to 16 channels), a Charge Time Measurement Unit (CTMU) for capacitive touch sensing, multiple UART/SPI/I²C interfaces, and unique deep-sleep peripherals including DSBOR (Deep Sleep Brown-Out Reset), DSWDT (Deep Sleep Watchdog Timer), and RTCC (Real-Time Clock Calendar) that continue to run while the CPU is asleep. The 'FV' variant indicates a wide-voltage (2.0V-5.5V) part versus the 'F' standard-voltage (1.8V-3.6V) variant.
The device uses a 16-bit modified Harvard RISC architecture with single-cycle instruction execution and hardware multiply support. Internal oscillator options eliminate the need for external crystals in many designs, reducing BOM cost. The 20-pin PDIP package provides breadboard-friendly through-hole mounting suited to prototyping, education, and legacy industrial designs.
Typical applications include battery-powered sensor nodes, wearable health monitors, remote controls, low-power wireless sensor networks, capacitive touch user interfaces, and industrial metering. The integrated CTMU simplifies touch-button and slider implementation without external timing circuits.
When designing with this part, leverage the deep-sleep modes aggressively: DSBOR, DSWDT, and RTCC retain functionality below 1µA. Use the internal FRC oscillator for active mode to minimize current draw, and switch peripherals off individually when not in use to maximize battery life.

Typical Applications
PIC24FV16KA301-E/P is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Wearable Health Monitors, Capacitive Touch User Interfaces, Remote Controls and Wireless Sensor Endpoints, Industrial Metering and Data Loggers, Educational and Hobby Electronics.
Battery-Powered IoT Sensor Nodes
The PIC24FV16KA301-E/P is well-suited for battery-powered IoT sensor nodes due to its XLP eXtreme Low Power technology with deep-sleep currents below 1µA, allowing multi-year battery life from a single coin cell. The wide 2.0V-5.5V operating range natively supports both 3.0V CR2032 coin cells and 3.7V Li-ion batteries without external regulators. The integrated 12-bit ADC with up to 16 channels handles multiple sensor inputs (temperature, humidity, light) while the 16KB Flash accommodates moderate-sized sensor-fusion firmware. Compared to 32-bit Cortex-M0 alternatives, the PIC24FV16KA301 offers lower active current at equivalent MIPS throughput and a simpler programming model with the free XC16 toolchain.
Recommended
Wearable Health Monitors
The PIC24FV16KA301-E/P fits wearable health monitors where extended battery life and small form factor matter more than raw CPU speed. Its nanoWatt XLP deep-sleep mode draws less than 1µA while retaining RTCC for accurate timestamping of health events, and the 16KB Flash supports heart-rate, step-counter, and BLE command-processing firmware. The wide 2.0V-5.5V range accepts a single 3.7V Li-ion cell directly without boost/buck conversion, minimizing quiescent losses. Integrated CTMU enables capacitive touch on small wearable enclosures without mechanical buttons, improving water resistance. The 20-pin PDIP through-hole package also simplifies wearable-prototype assembly on perfboard during early development.
Recommended
Capacitive Touch User Interfaces
The PIC24FV16KA301-E/P excels in capacitive touch user interfaces thanks to its integrated Charge Time Measurement Unit (CTMU), which simplifies touch-button, slider, and proximity-sensor implementation without dedicated touch controller ICs. The CTMU provides consistent capacitance measurement independent of supply voltage, supporting reliable touch detection across the 2.0V-5.5V range and through overlays up to several millimeters thick. With 17 GPIO pins and 16 ADC channels, a single PIC24FV16KA301 can serve multiple touch zones plus LEDs, haptic drivers, and communication interfaces. Deep-sleep current below 1µA enables battery-powered touch remotes and IoT control panels that last years on a single cell.
Recommended
Remote Controls and Wireless Sensor Endpoints
The PIC24FV16KA301-E/P is ideal for remote controls and wireless sensor endpoints where the MCU spends most of its time in deep sleep and wakes briefly to transmit. DSWDT (Deep Sleep Watchdog Timer) and RTCC operate below 1µA, enabling duty-cycled wake-up for sub-MHz wireless protocols like LoRa, Sub-GHz proprietary, or BLE beacons. The 32MHz performance at 16 MIPS handles pre-encryption, packet framing, and sensor aggregation in microseconds before returning to sleep. Wide voltage operation lets a single PIC24FV16KA301 pair with 2xAA alkaline cells (3.0V nominal, 2.0V end-of-life) without regulation, maximizing usable battery capacity over the product lifetime.
Recommended
Industrial Metering and Data Loggers
The PIC24FV16KA301-E/P suits metering and data-logging applications needing reliable EEPROM-backed parameter storage and RTC timekeeping. The 512-byte EEPROM stores calibration constants and logged events without external memory, while the RTCC provides timestamps in deep sleep at sub-microamp current. The 12-bit ADC with 16 channels accepts multiple sensor inputs from CT-operated current shunts, thermistors, and flow sensors common in industrial metering. Extended -40°C to +125°C temperature grade (E suffix) supports outdoor enclosures, factory floors, and uncontrolled industrial environments where commercial-grade parts would fail. PDIP through-hole packaging also simplifies conformal-coated retrofit installations.
Recommended
Educational and Hobby Electronics
The PIC24FV16KA301-E/P is ideal for educational and hobby projects because the 20-pin PDIP package fits standard breadboards and IC sockets, allowing students to swap chips during experiments without soldering. The free MPLAB X IDE and XC16 compiler provide a complete toolchain at no cost, and the PICkit 4 or Snap programmer supports in-circuit debugging and programming. The wide 2.0V-5.5V supply tolerance means beginners can power projects from a 9V battery through a simple LM7805 regulator without worrying about brown-out resets. Robust XLP peripherals and forgiving electrical characteristics make this an excellent teaching platform for embedded systems courses.

Key Differentiators

- Through-hole PDIP package for prototyping and legacy socket compatibility (vs PIC24FV16KA301-E/SO)
Design Notes
Leverage XLP deep-sleep modes aggressively for battery-powered designs. The PIC24FV16KA301-E/P draws less than 1µA in deep sleep with DSWDT and RTCC active, enabling multi-year operation on CR2032 coin cells. Configure unused peripherals to OFF in their respective PMDx registers rather than leaving them in reset, and avoid unnecessary ADC conversions. Use Sleep() with RTCC wake-up for periodic sensor sampling rather than busy-wait loops.
The extended-grade PIC24FV16KA301-E/P operates from -40°C to +125°C junction temperature, well beyond commercial 0-70°C and industrial -40 to +85°C ranges. For outdoor or industrial installations, ensure the PDIP package thermal resistance is acceptable. Estimated: at maximum 32MHz operation, typical supply current is around 8mA at 5V (~40mW), so self-heating is negligible and standard PCB copper pours are sufficient.
Do not confuse the PIC24FV16KA301 (wide-voltage 2.0V-5.5V) with the PIC24F16KA301 (standard-voltage 1.8V-3.6V) when sourcing parts - the wrong variant may behave erratically above 3.6V. Also verify the MCLR pin has a proper 10kΩ pull-up to VDD; a floating MCLR can cause spurious resets or programming failures. When using the internal FRC oscillator at 32MHz, the PLL must be configured correctly (CLKDIV register) or the core will not reach the rated MIPS.
Place a 100nF decoupling capacitor as close as possible to the VDD pin (pin 13) and a 10µF bulk capacitor on the supply rail. For analog measurements, add a small ferrite bead or 10Ω resistor between digital and analog VDD if using a shared rail. Route the crystal traces (OSC1/OSC2) short and direct, guarded by ground, when using an external crystal for precision timing applications.
