PIC24FV32KA301T-I/SS 概要
This part belongs to the PIC24F family of 16-bit microcontrollers. PIC24F devices combine a modified Harvard RISC CPU core with a rich peripheral mix including 12-bit ADC, comparators, CTMU (Charge Time Measurement Unit), RTCC, and configurable logic. They sit at the high-performance end of the 8/16-bit MCU spectrum, often used as migration targets for PIC16/PIC18 designs that have exhausted program-memory or peripheral headroom. The 'FV' voltage-supply variant supports wide-range 1.8 V to 3.6 V operation.
Key features of the PIC24FV32KA301T-I/SS include eXtreme Low-Power (XLP) technology with Deep Sleep modes supporting DSBOR, DSWDT, and RTCC running while the CPU is halted; 12-bit A/D converter with up to 16 channels and CTMU support for capacitive touch sensing; 16-bit timers, input capture, output compare, and configurable logic cells; and a peripheral pin-select (PPS) system that allows flexible function-to-pin mapping. It also provides a 16-bit data bus, hardware multiplier, and nested interrupts for responsive real-time performance.
Typical applications include IoT sensor nodes, wearable health monitors, remote controls, low-power wireless sensor hubs, capacitive touch user interfaces, battery-powered instrumentation, and any design where Deep Sleep current is a primary design constraint. The 20-pin SSOP variant suits compact PCBs while retaining sufficient I/O for human-interface and sensor front-ends.
When designing with this MCU, observe the maximum clock rate of 32 MHz at 3.3 V and derate accordingly at 1.8 V. Use Microchip's MPLAB X IDE with the XC16 compiler, and verify Deep Sleep current budgets in your actual PCB layout because leakage paths can dominate at <1 µA standby targets.

主な用途
PIC24FV32KA301T-I/SS の用途: 6 件s: IoT Sensor Node, Wearable Health Monitor, Capacitive Touch User Interface, Remote Control / Wireless HMI, Battery-Powered Instrumentation, Home Automation / Smart Sensor.
IoT Sensor Node
The PIC24FV32KA301T-I/SS suits battery-powered IoT nodes because of its eXtreme Low Power (XLP) Deep Sleep current below 1 µA, 16 MIPS throughput, and 5V-tolerant digital I/O. According to the Microchip family datasheet, DSBOR, DSWDT, and RTCC remain active in Deep Sleep, enabling multi-year coin-cell operation while still executing scheduled wake-and-transmit cycles. The 32 KB Flash accommodates a small RTOS or state-machine plus a wireless-protocol companion driver. Hardware multiplier accelerates sensor-fusion math. The CTMU can read capacitive soil-moisture or proximity sensors directly, removing an external touch IC. PPS (peripheral pin select) reassigns UART/SPI/I2C to different physical pins, simplifying antenna isolation. Wide 1.8 V-3.6 V operation allows direct connection to 2x AA alkaline or single Li-ion cells. This combination of low active current (~8 mA at 32 MHz), tiny Deep Sleep draw, and rich analog peripherals makes the PIC24FV32KA301T-I/SS a strong fit for wireless sensor nodes that spend >99% of the time in sleep and burst-transmit periodically.

Wearable Health Monitor
The PIC24FV32KA301T-I/SS is well-suited to wearable health monitors because of its <1 µA Deep Sleep current, integrated 12-bit ADC for biosensor front-ends, and CTMU for capacitive touch UI buttons. The 5 V-tolerant I/O lets it interface directly to analog-front-end ICs operating above VDD. With 32 KB Flash it can host heart-rate, SpO2, or temperature-sensor firmware and a small BLE companion driver without external memory. RTCC maintains accurate timestamps while the CPU is halted, essential for activity logging. PPS allows routing the I2C/SPI bus away from analog traces, reducing PCB crosstalk. At 16 MIPS the MCU executes signal-processing for pulse oximetry or step counting within tight duty cycles. Industrial -40C to +85C temperature rating ensures reliable operation next to body heat and inside cold-weather garments.
おすすめ
Capacitive Touch User Interface
The PIC24FV32KA301T-I/SS is a strong fit for capacitive touch UIs thanks to its on-chip CTMU (Charge Time Measurement Unit) which, combined with the 12-bit ADC, scans up to 16 touch electrodes without an external touch controller. According to the Microchip family datasheet, the CTMU operates in Sleep modes, so an idle product can wake on touch at microamp current. mTouch® libraries from Microchip provide ready-made firmware for buttons, sliders, and proximity sensors. The 32 KB Flash holds a touch UI plus wireless/BLE companion protocol stack. PPS remaps the CTMU output channels to any GPIO, simplifying PCB routing. Internal comparators enable guard-ring or self-capacitance measurement schemes. This removes $0.30-$0.50 from the BOM versus discrete touch ICs and reduces board area on appliances, IoT hubs, and consumer white goods.
おすすめ
Remote Control / Wireless HMI
The PIC24FV32KA301T-I/SS is appropriate for handheld remote controls because of its low active current (~8 mA at 32 MHz), CTMU capacitive touch sensing for sealed enclosures, and ability to wake from RTCC or button press in Deep Sleep below 1 µA. The 32 KB Flash supports a sub-GHz radio companion driver plus button/scroll-wheel firmware. The 16 MIPS throughput handles debounced key-scan, LED PWM dimming, and LCD segment driving in real time. 5 V-tolerant digital I/O tolerates ESD-signaling of recycled batteries, extending field reliability. PPS simplifies routing for SPI to radio, I2C to OLED, and PWM to backlight driver across an irregular PCB. The wide 1.8 V-3.6 V range supports 2x AA alkaline and single Li-ion chemistries without a boost converter.
おすすめ
Battery-Powered Instrumentation
The PIC24FV32KA301T-I/SS fits battery-powered instrumentation like handheld multimeters, portable gas detectors, and field data loggers because of its <1 µA Deep Sleep, 12-bit ADC, and integrated RTCC. The CTMU supports precision resistance/capacitance measurement by timing the discharge of an unknown capacitor against a reference, removing the need for a separate impedance-converter ASIC. 32 KB Flash is sufficient for calibration tables, user-interface menus, and data logging. Hardware multiplier enables digital filtering on sampled data without overrunning the 16 MIPS core. The 5 V-tolerant I/O accepts industrial-signaling inputs directly through resistive dividers. Industrial -40C to +85C operation suits outdoor and factory-floor environments. PPS allows the user to remap analog channels after PCB layout revisions without board rework.
おすすめ
Home Automation / Smart Sensor
The PIC24FV32KA301T-I/SS is a strong choice for smart-home sensors such as occupancy detectors, smart thermostats, and connected leak sensors thanks to its XLP Deep Sleep current below 1 µA, CTMU for ambient-light or capacitive user-interface buttons, and RTCC for time-stamping events. The 32 KB Flash fits Wi-Fi/Zigbee/BLE companion-processor firmware plus local control logic. The 12-bit ADC reads thermistor, PIR, or CO2-sensor analog outputs directly. 5 V-tolerant digital I/O accepts industrial-style pushbutton and dry-contact wiring without external protection. Wide 1.8 V-3.6 V supply allows direct operation from 2x AA or USB-derived rails. Industrial -40C to +85C operation handles outdoor and attic installations. PPS simplifies routing for mixed analog and digital signals on a small PCB.

設計ノート
Estimated: Active current at 32 MHz is roughly 8 mA at 3.3 V, so average system current for a 1% duty-cycle sensor node is about 80 µA plus Deep Sleep current. PIC24FV32KA301T-I/SS Deep Sleep current is documented as <1 µA typical at 25C, which means a 1000 mAh battery lasts several years. Always disable unused peripherals in software (PMDx bits) before entering Sleep and use DSBOR/DSWDT/RTCC wake sources selectively - leaving the ADC or comparator running in sleep can increase quiescent current by orders of magnitude.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 6) and a 10 µF bulk capacitor near the MCU power input. For analog applications, add a ferrite bead between the digital VDD and analog AVDD pins to suppress digital switching noise. Keep the analog inputs (AN0-AN15) routed away from switching traces and clock lines, and use a ground pour under the IC to provide a low-impedance return path. For 32 MHz operation, the SSOP package's exposed thermal pad (if present on your PCB footprint) should be soldered to a thermal relief pad connected to ground to dissipate transient switching current.
PIC24FV32KA301T-I/SS is rated only to 3.6 V on VDD even though the I/O are 5 V-tolerant - applying 5 V to VDD will damage the part. Always verify VDD with an oscilloscope during board bring-up because many SE/UW series PIC24F parts have higher VDD tolerance (5.5 V) and a careless cross-reference can destroy the chip. Also confirm the MCLR pin (pin 20) is pulled high through a 10 kΩ resistor - leaving it floating can cause spurious resets in noisy environments. Finally, use MPLAB X with the latest Device Pack to ensure CTMU and PPS register definitions match the silicon revision.
At 32 MHz CPU clock, fast GPIO toggling can produce ground bounce and supply noise. If the application drives high-speed signals (e.g., SPI >10 MHz), use series damping resistors (22-33 Ω) on the SPI lines and ensure the ground return path is uninterrupted. The CTMU-driven capacitive-touch electrodes must be guarded against moisture and ESD - add series resistors (1 kΩ) on each touch electrode and clamp reference transient current to 0 V using low-leakage TVS diodes for medical or outdoor applications.
