PIC24FV08KM102-E/SS - 16-bit 32MHz 8KB Flash XLP MCU | Microchip
MPN: PIC24FV08KM102-E/SS ✓ Hoạt độngPIC24FV08KM102-E/SS Tóm tắt
A 16-bit MCU is a microcontroller whose data path, registers and ALU are 16 bits wide, sitting hierarchically between 8-bit MCUs (PIC16, AVR) and 32-bit MCUs (PIC32, ARM Cortex-M). The PIC24F family specifically targets low-power embedded applications, occupying the cost/power sweet spot for sensor hubs, human-machine interfaces and battery-powered consumer devices. Within Microchip's portfolio the PIC24FV08KM102 sits inside the KM1xx sub-family of the PIC24F family, which adds a Configurable Logic Cell (CLC) and Peripheral Pin Select (PPS) for flexible peripheral routing.
Key features include a 12-bit ADC with up to 13 input channels, two analog comparators, a charge time measurement unit (CTMU) for capacitive touch, four 16-bit timers, capture/compare/PWM peripherals and multiple communication interfaces including UART, SPI and I2C. The on-chip RTCC, deep sleep current in the nanoamp range, and Peripheral Module Disable allow overall system draw to drop below 1 µA in sleep, which is why this part appears in long-life battery designs.
Architecturally, the device uses a modified Harvard bus with separate program and data paths, a 16-bit instruction set optimized for C compilation, and a wide operating voltage range from 2.0V to 5.5V. The PIC24FV (wide Vdd) variant extends the 1.8V–3.6V F-series limit up to 5V, making it compatible with legacy 5V analog and industrial buses without level shifters.
Typical applications include low-power sensor nodes, capacitive touch user interfaces, battery chargers and power monitors, industrial control panels, and portable medical accessories. When designing with this MCU, ensure PPS is configured before peripheral use and that the 12-bit ADC's acquisition time matches the source impedance to avoid gain errors.

Ứng dụng tiêu biểu
PIC24FV08KM102-E/SS phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Industrial 5V Control Panel, Portable Medical Accessory, Automotive Body Electronics, Smart Energy Meter / Sub-Meter.
Battery-Powered IoT Sensor Node
The PIC24FV08KM102-E/SS fits battery-powered IoT sensor nodes because its nanoWatt eXtreme Low Power architecture drops deep-sleep current into the sub-microamp range, the wide 2.0V-5.5V supply runs directly from a single Li-ion or 3xAA pack, and the 12-bit ADC with 13 input channels handles multiple sensors. The on-chip CTMU enables touch or capacitive proximity wake-up, while UART/SPI/I2C ports interface to a sub-GHz or BLE radio. Designers typically route the PIC24FV08KM102-E/SS between a sensor I2C bus and the radio module, keeping the CPU asleep until a CTMU threshold or ADC comparator fires.
Được đề xuất
Capacitive Touch User Interface
The PIC24FV08KM102-E/SS is a natural fit for capacitive touch panels because its CTMU measures sub-picofarad capacitance changes, and the 12-bit ADC converts them with high resolution. Combined with Peripheral Pin Select (PPS) the touch channels can be reassigned to any IO pin, simplifying PCB layout for sliders, wheels and matrix buttons. Designers use the MPLAB Code Configurator touch library to map capacitance to button events on this part. Typical use: front-panel control for appliances, white goods, and consumer audio gear running from a 5V supply.
Được đề xuất
Industrial 5V Control Panel
The PIC24FV08KM102-E/SS suits industrial 5V control panels because its PIC24FV wide-Vdd variant operates directly on 5V rails without level shifters, interfacing with legacy 5V analog sensors, optocouplers and 5V relay drivers. The 28-SSOP package gives easy hand-solder access for prototyping while remaining surface-mount for production. MCCP/SCCP PWM channels drive motor or valve actuators, and the 12-bit ADC reads 4-20mA loop signals through a burden resistor. Pair the MCU with a watchdog supervisor and brown-out reset for industrial EMC resilience.
Được đề xuất
Portable Medical Accessory
The PIC24FV08KM102-E/SS serves portable medical accessories because its extended -40C to +125C temperature grade handles sterilisation environments, the wide supply range accepts common medical bus voltages, and the 12-bit ADC plus on-chip EEPROM securely stores calibration data. The CLC block can implement hardware safety interlocks independent of firmware, supporting fail-safe designs. Realistic fits: pulse-oximeter signal conditioning front-end, glucose-meter temperature compensation, and disposable drug-delivery pump controllers.
Được đề xuất
Automotive Body Electronics
The PIC24FV08KM102-E/SS extended temperature grade (-40C to +125C) and wide 2.0V-5.5V supply allow it to operate from 12V automotive rails after a 5V regulator, handling body-domain tasks such as LED lighting controllers, mirror adjust, or seat-position memory. The CCP/PWM peripherals drive MOSFETs for LED dimming or small DC motors, while the ADC monitors current sense resistors. Although the E-grade part is not AEC-Q100 qualified, the same die is offered as PIC24FV08KM102-E/SS in production automotive designs when paired with a qualified upstream supervisor.
Được đề xuất
Smart Energy Meter / Sub-Meter
The PIC24FV08KM102-E/SS is a fit for low-cost smart energy meters and sub-meters because the 12-bit ADC with internal references can sample current transformers or shunt resistors, the CLC implements zero-crossing detection in hardware, and the UART/SPI/I2C links to a metrology AFE or wireless module. The wide 5V supply handles mains-derived rails through an isolated supply. With 8 KB Flash and 1 KB SRAM the firmware fits basic tariff, peak detection and Modbus/CAN reporting tasks.

Ghi chú thiết kế
Use the nanoWatt XLP sleep modes (Sleep, Deep Sleep, Retention Sleep) aggressively. Estimated: with the CPU idle and RTCC running from a 32.768 kHz crystal, total quiescent draw can fall below 1 µA at 3.3 V, which is critical for battery-powered IoT designs. Verify measured sleep current against the datasheet DC characteristics section before committing to a battery budget.
Place a 100 nF decoupling capacitor as close as possible to the VDD pins (pin 8 and pin 20 on the 28-SSOP package) and a 10 µF bulk capacitor near the MCU supply. Both VDD pins must be tied together on the PCB, and the VSS pins must share a single ground plane. The MCLR pin requires a 10 kΩ pull-up to VDD; add a 100 nF cap on MCLR for noise immunity per Microchip AN585.
Peripheral Pin Select (PPS) lets you remap digital peripherals to any digital IO pin, which simplifies PCB routing but introduces a small remap latency. Configure PPS once at startup using the __builtin_write_OSCCONL and PPS_unlock macros; do not change PPS mappings during interrupt service routines. Source: Microchip MPLAB XC16 peripheral library documentation.
The PIC24FV (wide-Vdd) and PIC24F (narrow-Vdd) variants have identical pinouts and Flash but different VDD ranges; substituting a PIC24F08KM102 into a 5V design will damage it. Always confirm the FV prefix for 5V-tolerant operation. Likewise, ensure the ADC acquisition time is configured for the source impedance - a default 2 µS Tad may not be enough for high-impedance sensors.
