PIC24FV16KA302T-I/ML 概要
What is a Microcontroller (MCU)? A microcontroller is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM and EEPROM), and programmable peripherals on one die. An MCU hierarchy looks like: 16-bit MCU -> microcontroller -> embedded controller -> semiconductor -> integrated circuit. The 16-bit MCU class typically delivers 10-100 MIPS with deterministic interrupt response, sitting between 8-bit MCUs (lower cost, lower performance) and 32-bit ARM Cortex-M MCUs (higher performance, larger code). The PIC24F family is renowned for ultra-low-power XLP technology with sub-uA deep-sleep current.
Key differentiating features include eXtreme Low Power (XLP) technology with sub-uA Deep Sleep current, 12-bit ADC with up to 16 channels, Charge Time Measurement Unit (CTMU) for capacitive touch sensing, Real-Time Clock and Calendar (RTCC) that runs even in Deep Sleep mode, plus DSBOR and DSWDT (Deep Sleep Brown-Out Reset and Deep Sleep Watchdog Timer). The 'T' suffix denotes tape-and-reel packaging; the 'I' indicates the industrial -40 °C to +85 °C operating temperature range.
The device is built on a Harvard-architecture PIC24F CPU core with 16-bit instructions, allowing compact code density. The CTMU peripheral enables touch buttons, sliders, and proximity sensing. The integrated RTCC eliminates external clock chips for time-stamped data logging in low-power products. With 17 user I/O pins in the 28-QFN variant, the device provides flexible mixed-signal design.
Typical applications include IoT sensor nodes, wearable fitness devices, handheld instrumentation, low-power wireless sensor networks, capacitive touch user interfaces, and battery-powered industrial data loggers. The Deep Sleep modes with running RTCC enable years of operation from a single coin cell.
When designing with this MCU, choose the device's integrated RTCC over external RTC chips when PCB real estate and BOM cost matter. Always characterize sleep-mode entry/exit timing against worst-case Wake-from-Sleep scenarios.

主な用途
PIC24FV16KA302T-I/ML の用途: 6 件s: IoT Wireless Sensor Node, Wearable Fitness Tracker, Capacitive Touch User Interface, Battery-Powered Industrial Data Logger, Handheld Medical Monitoring Device, Low-Power Wireless Sensor Network Endpoint.
IoT Wireless Sensor Node
The PIC24FV16KA302T-I/ML is a great fit for IoT sensor nodes: its 1.8-3.6 V wide VDD range accepts single-cell Li-ion or 2xAA battery stacks directly without an LDO. The 32 MHz / 16 MIPS core handles sensor fusion, encryption, and radio protocol stacks in real time. XLP Deep Sleep current in the nano-amp range combined with the always-on RTCC enables multi-year battery life. Typical design uses 17 user I/O to drive SPI/IO2 sensors, a UART radio module, and status indicators. Holtek power design tip: duty-cycle the radio transmit at less than 1 percent to maximize battery life. Per the PIC24FV16KA304 family datasheet, integrating the CTMU allows capacitive moisture and proximity sensing without extra analog front-end ICs, reducing BOM cost by approximately $0.50 per node.
おすすめ
Wearable Fitness Tracker
The PIC24FV16KA302T-I/ML fits wearable fitness trackers because of its XLP sub-uA Deep Sleep current and wide 1.8-3.6 V supply that pairs with coin-cell and Li-Po batteries. The 12-bit ADC with up to 16 channels reads heart-rate, motion, and skin-temperature sensors simultaneously. The CTMU enables capacitive touch buttons and gesture sensing on the wristband without mechanical switches. With 17 user I/O, the MCU can drive an SPI OLED display, an IO2 accelerometer, and a Bluetooth Low Energy radio. The integrated RTCC keeps accurate timestamps in sleep logs. Trade-off: a 32-bit Cortex-M0+ might offer faster DSP for advanced heart-rate variability algorithms, but the PIC24F's lower cost and simpler toolchain are compelling for entry-to-consumer wearables.
おすすめ
Capacitive Touch User Interface
The PIC24FV16KA302T-I/ML is ideal for capacitive touch user interfaces thanks to its integrated CTMU peripheral, which measures capacitance with femto-farad sensitivity using the 12-bit ADC. This enables reliable touch buttons, sliders, and wheel encoders without dedicated touch ICs, reducing BOM cost and PCB area. The 32 MHz core can poll up to 16 touch channels every 8 ms with sub-1 percent CPU load. The 1.8-3.6 V supply supports battery-powered, ranging to USB-powered, ranging to 24V industrial panels with appropriate front-end scaling. Trade-off: the CTMU requires careful PCB layout with ground flooding under touch pads; follow the Microchip AN2189 application note layout guidelines for noise-immune environmental designs.
おすすめ
Battery-Powered Industrial Data Logger
The PIC24FV16KA302T-I/ML fits battery-powered industrial data loggers because of its always-on RTCC that timestamps measurements during Deep Sleep, eliminating external RTC chips. The wide 1.8-3.6 V supply operates from 2xAA or single-cell Li-ion for multi-year deployments. With 17 user I/O, the device can drive IO2/SPI temperature, humidity, and pressure sensors plus a micro-SD card interface. The 12-bit ADC with 16 channels handles simultaneous multi-sensor sampling. The 16 KB Flash stores weeks of compressed data; upgrade to PIC24FV32KA302-I/ML for months of storage. Holtek power design tip: use the DSWDT to recover from software hangs in remote deployments without field service calls.
おすすめ
Handheld Medical Monitoring Device
The PIC24FV16KA302T-I/ML is suitable for handheld medical monitoring devices such as pulse oximeters, glucose meters, and spirometers, where its 12-bit ADC provides sufficient resolution for clinical-grade sensor readings and its XLP technology supports battery operation through a clinic shift. The CTMU enables capacitive touch buttons for hygienic, sealed user interfaces. The 16-bit core runs real-time DSP for heart-rate and respiration algorithms. With 17 user I/O, the device connects to SPI/IO2 sensors, UART/BLE radios, and segmented LCDs. Trade-off: FDA/IEC 62304 compliance requires additional firmware V&V, but the PIC24F family has established use in FDA-cleared devices. Per the PIC24FV16KA304 family datasheet, the RTCC enables accurate time-stamping for diagnostic records.
おすすめ
Low-Power Wireless Sensor Network Endpoint
The PIC24FV16KA302T-I/ML is a strong fit for low-power wireless sensor network endpoints, where its XLP sub-uA Deep Sleep current combined with a sub-GHz or BLE radio enables multi-year coin-cell operation. The 32 MHz core runs ZigBee, LoRa, BLE stack, or proprietary protocols. The 17 user I/O provides flexible IO2/SPI/UART sensor and radio connectivity. Per the PIC24FV16KA304 family datasheet, the integrated RTCC enables synchronized time-slot protocols without external RTC. Holtek trade-off: at 16 MIPS, this MCU handles low-rate sensor telemetry well; high-rate audio/video streaming requires 32-bit Cortex-M4-class performance.

設計ノート
Estimated: at VDD=3.3 V and CPU active at 32 MHz, core current is approximately 8 mA per the PIC24FV16KA304 family datasheet. In Deep Sleep mode, total current drops to sub-uA (typically 20-100 nA) with RTCC running. For battery-powered designs, duty-cycle the CPU below 1 percent to maximize runtime. Always use DSBOR (Deep Sleep Brown-Out Reset) to recover from low-voltage brown-out conditions during sleep, especially on battery-powered systems where VDD can sag unpredictably.
For the 28-QFN (6x6 mm) package, Microchip recommends a 4-layer PCB with continuous ground plane under the package thermal pad. The exposed pad must be soldered to the ground plane for mechanical and thermal reliability. Decoupling: place a 100 nF ceramic capacitor within 3 mm of VDD pin 6, plus a 10 uF bulk capacitor near the supply rail. For CTMU capacitive touch designs, follow AN2189 guidelines with ground flooding around touch pads and no ground pour under the touch electrode itself.
Do not exceed the absolute maximum VDD of 3.6 V on the 'FV' variant; the device is NOT 5 V tolerant on I/O. For programming/debugging, use the ICSP interface with PGECX/PGEDX pins - these are 3.3 V logic, not 5 V. Configuration bits must be set before code runs; an unconfigured device will not execute user code. For production programming, use Microchip's MPLAB X IPE or a third-party programmer with the latest device database. Watch out for the VDD rise minimum that will start the BOR correctly.
