PIC24FV32KA302-I/SS 개요
A 16-bit microcontroller (MCU) is a programmable processor that uses a 16-bit data path and instruction word, offering higher computational throughput, richer peripherals, and larger addressable memory than 8-bit MCUs while maintaining comparable code density. The PIC24F family specifically targets ultra-low-power embedded applications by combining a modified Harvard RISC architecture with nanoWatt XLP technology, fitting in the broader taxonomy: 16-bit MCU -> microcontroller -> embedded processor -> semiconductor IC.
Key features include nanoWatt XLP technology with deep-sleep currents under 1 µA, dedicated low-power peripherals like DSBOR (deep-sleep brown-out reset), DSWDT (deep-sleep watchdog timer), and RTCC (real-time clock calendar) that run in deep sleep mode, and configurable peripherals such as 5 CCP/ECCP, 3 UART, 2 SPI, 2 I2C, and a 12-bit ADC with 16 channels. The 32 MHz operation delivers up to 16 MIPS throughput for DSP-class signal processing in low-power systems.
The architecture uses a 16-bit modified Harvard core with single-cycle hardware multiply and divide, dual-cycle Flash read with prefetch, and a peripheral engine that supports DMA to RAM for energy-efficient background data movement. Its 5V tolerant digital I/O pins allow direct interfacing to legacy 5V logic without level shifters, simplifying mixed-voltage designs.
Typical applications include battery-powered IoT sensor nodes, wearable health monitors, remote controls, low-power wireless sensor networks, energy harvesting systems, and portable medical devices. The XLP features and wide supply range suit any design where sleep current, battery life, and active-mode MIPS-to-mA efficiency dominate BOM decisions.
When designing with this MCU, prioritize pin remap assignments early in the schematic to avoid routing congestion on the 28-pin SSOP, and ensure the CTMU is calibrated for absolute capacitance measurements if used for capacitive touch. Selecting SSOP over QFN improves hand-rework and breadboard prototyping for low-volume builds.

Battery-Powered IoT Sensor Nodes
The PIC24FV32KA302-I/SS is purpose-built for battery-powered IoT sensor nodes because its nanoWatt XLP technology delivers deep-sleep currents below 1 µA while the integrated RTCC keeps accurate wall-clock time during sleep. With 32 KB Flash it accommodates BLE/Zigbee/Thread protocol stacks plus sensor-fusion code, and the 12-bit ADC with 16 channels handles multi-sensor acquisition. The wide 1.8V-3.6V VDD range accepts a Li-ion cell across its entire discharge curve, eliminating boost/buck regulators. The CTMU enables precise temperature and capacitive-touch measurements without external analog ASICs, reducing BOM cost in space-constrained wireless sensor designs.
추천
Wearable Health Monitors
The PIC24FV32KA302-I/SS suits wearable health monitors where size, weight, and battery life dominate BOM decisions. Its SSOP-28 package provides a compact 5.30 mm footprint for wristbands and patches, while the 16 MIPS throughput executes heart-rate, SpO2, and step-count algorithms in real time without external DSP. The CTMU measures bio-impedance and capacitive touch (e.g., skin contact sensing) with hardware calibration, and the XLP deep-sleep mode plus RTCC alarm enable duty-cycled measurements that extend coin-cell life beyond six months. The 5V-tolerant I/O allows direct connection to analog front-ends with 5V excitation signals.
추천
Remote Controls and HID Devices
The PIC24FV32KA302-I/SS powers infrared/RF remote controls, game controllers, and keyboard/mouse HID devices because of its low active current and ultra-low sleep current that preserve battery life across years of standby. The CTMU with capacitive-touch capability replaces mechanical buttons with touch sliders, reducing mechanical wear and simplifying sealing against dust and moisture. With three UART, two SPI, and two I2C peripherals, it concurrently drives an RF transceiver, IR LED driver, and OLED display. The 32 KB Flash holds USB HID class descriptors, IR protocols (RC5/RC6/SIRC), and BLE pairing logic.
추천
Industrial Sensor Transmitters
The PIC24FV32KA302-I/SS industrial variant operates from -40C to +85C with the 5V-tolerant I/O enabling direct interface to legacy 4-20 mA loop-powered sensors and 24V industrial signaling via external protection. Its 12-bit resolution and 16-channel ADC handle multiple transducer inputs (temperature, pressure, flow) with hardware averaging and CTMU-based diagnostics. The 32 KB Flash accommodates Modbus RTU or HART protocol stacks, calibration coefficients, and digital signature verification for safety-critical installations. Its wide 1.8V-3.6V supply tolerates brownout events common in industrial power systems.
추천
Energy Harvesting Systems
The PIC24FV32KA302-I/SS suits energy-harvesting wireless switches and self-powered sensor nodes because its nanoWatt XLP sleep current (sub-µA) means the MCU consumes less power than the leakage of typical support components. The wide 1.8V-3.6V VDD range lets it operate directly from rectified solar, thermoelectric, or piezoelectric harvesters without boost regulation. The DSWDT and DSBOR functions continue to monitor the supply and reset conditions while the MCU is in deep sleep, ensuring reliable cold-start from fully depleted storage. CTMU measurements of harvested energy levels enable adaptive duty-cycling to match available power.
추천
Portable Medical Devices
The PIC24FV32KA302-I/SS targets portable medical devices such as glucose meters, pulse oximeters, and nebulizers where IEC 62304 firmware lifecycle and reliability requirements apply. Its 32 KB Flash and 2 KB RAM are sufficient for FDA Class II embedded firmware, while the 12-bit ADC delivers the resolution needed for electrochemical sensor readout (e.g., glucose test strips). The XLP architecture minimizes heat dissipation during skin contact measurements, improving patient comfort and battery runtime. Hardware CRC and memory-mapped checksum options simplify verification activities in regulated design processes.

설계 노트
Estimated: power budget at 3.3V, 16 MIPS active compute is about 8 mA (typical), while XLP deep-sleep with RTCC running is under 1 µA. For a duty cycle of 1% active and 99% sleep, average current is approximately 80 µA, which allows 250 mAh coin-cell operation for over 4 months. Configure the DSBOR and DSWDT to run during sleep to retain brownout and watchdog protection without exiting sleep state.
Place a 100 nF decoupling capacitor within 5 mm of each VDD/VDDCORE pin pair, and add a 10 µF bulk capacitor near the package. The 28-SSOP land pattern requires 0.65 mm pitch pads; ensure the PCB has adequate ground pour under the SSOP body to improve thermal dissipation. For designs using the CTMU, route the analog input traces as guarded differential pairs to minimize leakage.
Do not exceed VDD of 3.6V even though digital inputs are 5V tolerant - the 5V tolerance applies only to inputs, not VDD. The PIC24F V variant is mandatory for designs accepting 5V logic levels; the non-V PIC24F32KA302 has stricter VDD limits. Always configure unused I/O pins as outputs low to minimize sleep current and ensure no floating inputs cause spurious interrupts during deep sleep.
