PIC24FV16KA304-I/ML Übersicht
A 16-bit microcontroller (MCU) is an integrated circuit that combines a 32 MHz CPU core, program memory, data memory, peripherals, and I/O into a single chip. The PIC24F family sits between 8-bit PIC MCUs and 32-bit PIC32 devices, offering higher performance than 8-bit parts while maintaining the low-power and low-cost advantages of the PIC ecosystem. The PIC® XLP™ (eXtreme Low Power) designation indicates that this part family was engineered specifically for ultra-low quiescent current draw, with multiple deep-sleep modes suitable for battery-powered products.
Key differentiating features include 17 digital I/O pins, a 12-bit ADC, 5 capture/compare/PWM peripherals, a Charge Time Measurement Unit (CTMU) for capacitive measurement, and serial peripherals (I2C, SPI, UART). The wide 1.8V-5.5V supply voltage enables direct Li-ion battery operation, while deep-sleep modes draw less than 20 nA typical quiescent current. The 44-QFN package (8x8 mm) includes an exposed thermal pad for improved heat dissipation in continuous-operation applications.
The PIC24FV16KA304 architecture uses a modified Harvard structure with separate program and data paths, achieving 32 MHz / 16 MIPS throughput. The integrated RTCC (Real-Time Clock Calendar), DSBOR (Deep Sleep Brown-Out Reset), and DSWDT (Deep Sleep Watchdog Timer) all operate from a separate low-power domain, allowing system timekeeping and supervision while the main CPU is asleep. This combination is the core XLP value proposition for battery-powered designs.
Typical applications include battery-powered IoT sensor nodes, wearable health monitors, remote controls, electronic shelf labels, smart meters, low-power wireless sensor networks, and any portable device that must run for months or years on a single coin cell or AA battery. The CTMU peripheral is particularly valuable for capacitive touch buttons and sliders.
When designing with this MCU, choose decoupling capacitors (100 nF + 10 µF) close to the VDD pins and bond the exposed pad (EP) to a grounded copper pour for both thermal and electrical reasons. The ICD/PGD and PGC pins must be reserved for in-circuit debugging unless you give up debug visibility in production.

Typische Anwendungen
PIC24FV16KA304-I/ML ist geeignet für 6 Anwendungs: Battery-Powered IoT Sensor Nodes, Wearable Health Monitors, Remote Controls (Consumer IR / RF), Electronic Shelf Labels (ESL), Smart Meters (Water / Gas / Heat), Industrial Sensor Transmitters (4-20 mA / WirelessHART).
Battery-Powered IoT Sensor Nodes
The PIC24FV16KA304-I/ML is purpose-built for battery-powered IoT sensor nodes thanks to its deep-sleep current under 20 nA typical and 1.8-5.5 V wide-voltage input that accepts a single CR2032 coin cell or 2x AA alkaline pack directly. Its 32 MHz / 16 MIPS performance handles sensor sampling and protocol stack tasks, while the XLP deep-sleep mode with active RTCC keeps time-of-day awareness at nanoamp-level draw. Placed between a battery and a low-power radio (e.g., Sub-GHz or BLE module) with 100 nF + 10 µF decoupling at VDD, this MCU can run a duty-cycled sensor node for 3-5 years on a single coin cell. Compared with 8-bit PIC MCUs, it adds DSP extensions and larger 16 KB Flash for over-the-air firmware update routines.
Empfohlen
Wearable Health Monitors
The PIC24FV16KA304-I/ML fits wearable health monitors (heart rate, SpO2, temperature patches) where its 12-bit ADC and CTMU peripheral enable direct connection to analog front-ends and capacitive touch electrodes. The wide 1.8-5.5 V input eliminates boost regulators for Li-ion coin cells, shrinking the BOM by 4-6 passive components. Active-mode draw around 200 µA/MHz keeps thermal management trivial in skin-contact devices, while the 44-QFN 8x8 mm package fits inside a typical 25 mm patch form factor. Engineers typically pair it with an SPI-connected bio-sensor AFE and a low-power BLE module, using the RTCC to schedule periodic wake-ups.
Empfohlen
Remote Controls (Consumer IR / RF)
The PIC24FV16KA304-I/ML is well suited for universal remote controls, RF key fobs, and smart-home handheld controllers thanks to its deep-sleep draw under 20 nA, which preserves battery life across months of standby. The 17 I/O pins support a full matrix keypad (up to 4x4) plus IR LED drivers and buzzer outputs, while the 32 MHz CPU encodes NEC/RC5/RC6 IR protocols without burdening the firmware stack. Its 1.8-5.5 V input accepts a single CR2032 directly, eliminating boost circuitry. With 16 KB Flash, the part easily accommodates multiple protocol libraries, IR code databases, and device-pairing logic.
Empfohlen
Electronic Shelf Labels (ESL)
The PIC24FV16KA304-I/ML is widely deployed in electronic shelf labels where thousands of battery-powered displays receive pricing updates via Sub-GHz RF or NFC. Its deep-sleep current and 1.8-5.5 V wide-voltage input allow ESL labels to operate 5-10 years on coin cells, while the 32 MHz CPU handles RF packet decoding and e-paper display refresh bursts quickly enough to return to sleep. The 16 KB Flash accommodates link-layer stack, display drivers, and product-SKU storage. Pair it with a low-power e-paper driver over SPI and a 2.4 GHz or Sub-GHz transceiver.
Empfohlen
Smart Meters (Water / Gas / Heat)
The PIC24FV16KA304-I/ML fits battery-powered smart meters (water, gas, heat) that must run 10-15 years on a primary lithium cell. Its XLP architecture with sub-20 nA deep-sleep current and DSBOR/DSWDT supervision ensures autonomous operation across extreme temperature swings, while the 12-bit ADC interfaces directly with pulse-output flow sensors or thermistor bridges. The 32 KB maximum Flash variant (PIC24FV32KA304) provides headroom for wireless M-Bus or LoRaWAN stack integration.
Empfohlen
Industrial Sensor Transmitters (4-20 mA / WirelessHART)
The PIC24FV16KA304-I/ML operates in industrial loop-powered sensor transmitters where its industrial -40°C to +85°C temperature range and 1.8-5.5 V input tolerate unregulated 24 V loops with simple linear regulation. Its 12-bit ADC and PGA interface directly with bridge pressure/temperature sensors, while the 32 MHz CPU runs compensation math in real time. The 44-QFN package offers a small footprint suitable for in-head transmitter enclosures, and the XLP sleep modes extend battery life in wireless HART field devices to multi-year service intervals.

Wichtigste Unterscheidungsmerkmale

- 32 KB Flash headroom for OTA-ready firmware (vs. PIC24FV32KA304-I/ML)
- Tape-and-reel packaging for high-volume production (vs. PIC24FV16KA302T-I/ML)
Designhinweise
Place a 100 nF decoupling capacitor as close as physically possible to every VDD pin (pins 14 and 33 on the 44-QFN) plus a shared 10 µF bulk capacitor on the main VDD rail. The PIC24FV16KA304 draws fast transient currents when exiting deep-sleep, and inadequate decoupling can cause voltage dips that trigger spurious brown-out resets. For battery applications, use a low-ESR ceramic (X5R/X7R) on the VCAP pin to stabilize the internal voltage regulator output.
The exposed thermal pad (EP) on pin 45 of the 44-QFN package MUST be soldered to a grounded copper pour of at least 1 square inch (≈ 6.45 cm²) for both thermal dissipation and electrical ground reference. Skipping the EP solder connection is a common production defect that causes the MCU to overheat at sustained 32 MHz operation and increases EMI susceptibility on analog ADC channels.
Keep the SOSC secondary oscillator traces (pins 17-18) short and routed over a continuous ground plane to minimize leakage into the 32 kHz crystal circuit. Analog ADC inputs (AN0-AN10) should be routed away from digital switching signals (PWM, UART, SPI clocks) and bypassed with a small RC filter when high-impedance sensors are connected. The ICD pins TMS/TCK/TDI on pins 22-24 must be accessible or routed to an in-circuit debug header for production firmware bring-up.
Do not confuse the PIC24FV16KA304 (wide-voltage 1.8-5.5 V) with the PIC24F16KA304 (narrow-voltage 1.8-3.6 V). Substituting F for FV in 5 V systems will permanently damage the MCU due to absolute-maximum Vdd violation. Also note that 'I' (industrial -40C to +85C) and 'E' (extended -40C to +125C) suffixes use different package thermal grades; verify the desired temperature range matches the production environment before PCB layout finalization.
