PIC24FV32KA304-E/ML 概要
What is a 16-bit microcontroller? A 16-bit MCU executes instructions on 16-bit-wide data paths, giving a better balance between code density and arithmetic throughput than 8-bit parts while remaining simpler than 32-bit Cortex-M devices. The PIC24F family from Microchip targets low-power embedded designs and sits in the broader hierarchy: microcontroller -> embedded MCU -> 16-bit MCU -> low-power MCU -> power management node. The PIC24FV variant extends the VDD range higher than the standard PIC24F, enabling 5V analog signal interfacing.
Key features include a 16 MIPS 16-bit CPU core with modified Harvard architecture, a 12-bit A/D converter with up to 16 channels, a 16-bit/32-bit timer/counter block, multiple UART/SPI/I2C peripherals, a Charge Time Measurement Unit (CTMU) for capacitive touch and precise time measurement, and nanoWatt XLP technology that typically draws less than 20 nA in Deep Sleep mode. The 44-pin QFN package exposes up to 17 general-purpose I/O pins on this code.
Typical applications include battery-powered IoT sensor nodes, low-power wireless modules, capacitive touch user interfaces, portable medical monitoring devices, energy harvesting systems, smart meters, and consumer electronics that require long battery life combined with 5V-tolerant analog I/O. The combination of 32 KB Flash and 2 KB RAM fits small RTOS or bare-metal designs.
When designing with this part, ensure the VDD rail stays within the datasheet limits and use the internal LDO mode where supported. For capacitive touch designs, follow the CTMU layout guidelines in the Microchip TB3019 application note. Pricing is shown as of 2026-09-30 from authorized distributors and depends on quantity breaks.

主な用途
PIC24FV32KA304-E/ML の用途: 6 件s: Battery-Powered IoT Sensor Nodes, Capacitive Touch User Interface, Portable Medical Monitoring Devices, Smart Metering and Energy Harvesting, Industrial Sensor Transmitters, Consumer Remote Controls and HIDs.
Battery-Powered IoT Sensor Nodes
The PIC24FV32KA304-E/ML is ideal for battery-powered IoT sensor nodes because it delivers 16 MIPS of 16-bit processing while drawing less than 20 nA in Deep Sleep mode. Its 32 KB Flash and 2 KB RAM are sufficient for BLE/Zigbee stack snippets or LoRaWAN MAC code, and the 1.8 V to 5.5 V VDD range lets the MCU run directly from a 3.6 V lithium-thionyl chloride primary cell. The unique RTCC that runs in Deep Sleep keeps wall-clock time accurate without waking the core, dramatically extending battery life in remote deployments.
おすすめ
Capacitive Touch User Interface
The on-chip CTMU peripheral enables robust capacitive touch buttons, sliders, and proximity sensing with minimal firmware overhead. Hardware-implemented charge timing removes the need for external touch ICs and provides stable readings even under moisture or noise. The 32 KB Flash is sufficient for mTouch reference firmware plus the application layer, while the 1.8 V to 5.5 V range simplifies operation directly from a USB-powered 5 V rail. Engineers should follow Microchip TB3019 layout guidelines for optimal touch performance.
おすすめ
Portable Medical Monitoring Devices
The PIC24FV32KA304-E/ML fits portable medical monitors such as pulse oximeters, glucose meters, and wearable patches. Its 12-bit ADC with up to 16 channels can read multiple biosensors simultaneously, and the extended -40C to +125C temperature grade covers sterilization and skin-contact thermal ranges. The Deep Sleep current under 20 nA allows multi-month battery life on coin cells. The wide VDD range simplifies direct connection to a single lithium primary or rechargeable cell.
おすすめ
Smart Metering and Energy Harvesting
In smart electricity, gas, or water meters, the PIC24FV32KA304-E/ML provides the computation headroom for metering algorithms plus the low sleep current required for 10+ year battery life. The on-chip DSBOR and DSWDT allow brown-out recovery and watchdog operation even in Deep Sleep, which is critical for unattended endpoints. The 12-bit ADC can read shunt current sensors or temperature transducers, and the RTCC keeps accurate time-of-use billing data.
おすすめ
Industrial Sensor Transmitters
For 4-20 mA loop-powered or industrial wireless transmitters, the PIC24FV32KA304-E/ML delivers industrial temperature operation and 5 V tolerance for analog sensor interfacing. The CTMU can measure RTD or thermistor resistance accurately through charge-time methods, eliminating some analog front-end components. The 32 KB Flash holds wireless stack snippets such as WirelessHART or IO-Link device firmware, while 2 KB RAM handles protocol state buffers.
おすすめ
Consumer Remote Controls and HIDs
The PIC24FV32KA304-E/ML is a strong fit for TV remote controls, air-conditioner remotes, game controllers, and other human-interface devices that spend most of their life asleep. Its sub-20 nA Deep Sleep preserves coin-cell life for years, while the IR timer/counter and CTMU enable capacitive buttons plus IR transmit on a single chip. The 32 KB Flash fits full HID descriptor tables and wake-on-touch or wake-on-IR routines.

設計ノート
Estimated: Deep Sleep current is typically less than 20 nA with RTCC and DSWDT disabled. Enable only the peripherals required for wake (DSBOR, DSWDT, RTCC) to minimize sleep current. Use Idle mode when CPU clock can stop but peripherals must run; Sleep when the entire core may stop. Refer to the PIC24F Family Reference Manual DS39708 for sleep configuration.
Place a 100 nF decoupling capacitor as close as possible to each VDD pin and a single bulk capacitor (4.7 uF to 10 uF) on the main VDD rail. The VCAP pin requires a low-ESR 1 uF to 10 uF capacitor to ground for internal regulator stability. The QFN package exposed pad must be soldered to a continuous ground plane for thermal dissipation.
Do not exceed 5.5 V on any VDD pin or the absolute maximum ratings. Configure unused I/O as outputs low to minimize current. When migrating from PIC24F to PIC24FV variants, confirm 5 V analog tolerance is required, since both share pinouts but differ in VDD range. Use Microchip's MPLAB X IDE and XC16 compiler for proper configuration bit programming.
Keep analog input traces short and routed away from digital switching lines to minimize ADC noise coupling. Provide a ground ring around the CTMU touch electrodes and keep the sensor traces of similar length for matched charge timing. Follow Microchip application note TB3019 for capacitive touch PCB layout recommendations.
