A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (typically Flash), working RAM, and a rich set of peripherals on one die. Microcontrollers sit at the lowest tier of embedded computing beneath microprocessors and SoCs, and they dominate the market for low-power, deterministic, cost-sensitive products such as sensor nodes, white goods, and wearable electronics. The PIC24F family in particular occupies the 16-bit tier of Microchip's portfolio between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX/dsPIC families, offering a meaningful performance step (16-bit data path, 24-bit instructions, hardware DSP-like operations) at modest cost and power.
Key features of the PIC24FV08KM102-I/SS include: nanoWatt XLP sleep currents in the nanoamp range for battery-backed applications, a 12-bit A/D converter with up to 12 channels, multiple Capture/Compare/PWM modules, a Configurable Logic Cell (CLC), comparators, and integrated peripherals such as Brown-out Reset, Low-Voltage Detect, Power-on Reset, PWM, and a Watchdog Timer. It also supports up to 23 I/O pins in the 28-pin SSOP package, giving designers ample headroom for mixed-signal interfaces. The wide 2.0V to 5.5V VDD range is unusual for PIC24F devices and simplifies designs that must operate from a single-cell Li-ion as well as a regulated 5V supply.
Architecturally, the PIC24FV08KM102 uses a modified Harvard CPU with a 16-bit data path and 24-bit instruction word, plus a hardware Multiply-Divide unit that completes a 16x16 multiply in a single cycle. The CLC peripheral is noteworthy: it allows the user to configure combinational and sequential logic from on-chip signals in firmware, replacing small external glue-logic ICs (gates, muxes, latches) with on-die equivalents - a feature Microchip also promotes for BOM reduction in motor-control and lighting designs.
Typical applications include low-power sensor interfaces, consumer electronics (remote controls, e-readers, fitness wearables), portable medical devices, industrial control nodes, battery chargers, smart-home sensors, USB/HID peripherals, and any low-pin-count mixed-signal design that benefits from a wide VDD range. Designers should note that the 28-SSOP footprint is the same as the pin-compatible PIC24F08KM102 (5V-only) variant, which is helpful when migrating between 3V and 5V rails. Pricing references are current as of 2026-09-30 from DigiKey and Mouser listings for the -40C to +85C industrial-grade -I/SS device.

典型應用
PIC24FV08KM102-I/SS 適用於 7 應用s: Battery-Powered Sensor Node, Industrial Control Node, Consumer Electronics Remote Control, Portable Medical Device, Smart Home Sensor Hub, USB/HID Peripheral Controller, LED Lighting Controller.
Battery-Powered Sensor Node
The PIC24FV08KM102-I/SS is a strong fit for battery-powered sensor nodes because it combines nanoWatt XLP technology (sleep currents in the nanoamp range) with a wide 2.0V-5.5V VDD range that lets it run directly from a single Li-ion, two AA cells, or a 3.3V regulated rail. The 12-bit ADC with up to 12 channels handles typical sensor front-ends (temperature, humidity, pressure) without an external analog front-end, while the Configurable Logic Cell (CLC) replaces small external gates used for sensor wake-up timing. Compared with switching to a higher-core MCU, the KM102 keeps active current and BOM cost low for periodic-sampling wireless sensor nodes.
推薦
Industrial Control Node
In a 24V industrial control node where the system is locally regulated to 5V, the PIC24FV08KM102-I/SS provides the digital control plane: PWM outputs for actuator drive, Capture inputs for quadrature encoder feedback, and Brown-out Reset plus Watchdog for field reliability. The -40C to +85C industrial temperature rating suits most cabinet environments, and the on-chip comparators can implement hardware overcurrent protection without an external supervisor IC. The 23 I/O pins are sufficient for typical 4-channel PWM + I2C + UART + discrete I/O nodes.
推薦
Consumer Electronics Remote Control
Low-cost IR/RF remote controls benefit from the PIC24FV08KM102-I/SS because its nanoWatt XLP sleep modes keep quiescent current negligible on coin-cell or alkaline pairs, while its PWM and Capture modules directly drive IR LED modulation or RF transceivers. The 8 KB Flash comfortably holds protocol stacks (RC5/RC6, NEC, BLE HID bridges), and the wide VDD range allows the same PCB to support both 3V coin-cell and 5V USB-powered configurations. Designers can replace external glue logic with the on-chip CLC to keep BOM cost under USD 1.
推薦
Portable Medical Device
Portable medical peripherals such as glucose meters, pulse-oximeter front-ends, and wearable patch controllers use the PIC24FV08KM102-I/SS for its wide VDD range (single Li-ion or 2xAA), low sleep current, and integrated 12-bit ADC for sensor readout. The hardware 16x16 multiplier accelerates simple DSP-like filtering of photoplethysmography or impedance signals, and the CLC peripheral replaces small analog-timer ICs. Designers must validate IEC 60601-1 and IEC 62304 compliance paths at the system level; the -I industrial grade suffices for body-worn accessories.
推薦
Smart Home Sensor Hub
Smart-home sensor hubs (Zigbee/Sub-GHz bridge nodes, BLE beacons, LoRaWAN end nodes) commonly use the PIC24FV08KM102-I/SS as a host MCU because its PWM, UART, SPI, and I2C peripherals cover the radio + sensor bus, while its nanoWatt XLP sleep modes extend battery life between transmissions. The 28-SSOP footprint is hand-solderable for prototyping and the wide 2.0V-5.5V range lets a single board support battery, USB, and PoE-derived rails. The CLC can be configured to wake the MCU on a radio IRQ without an external interrupt expander.
推薦
USB/HID Peripheral Controller
For low-cost USB HID peripherals (keyboards, mice, presentation clickers, custom input devices), the PIC24FV08KM102-I/SS can act as the device-side controller when paired with an external USB FS transceiver. The 28-SSOP footprint exposes enough I/O for a matrix-scanned keyboard plus indicator LEDs, and the CLC peripheral debounces key presses in hardware to reduce firmware wake-ups. Designers who need full-speed USB OTG on-chip should consider the PIC24FJ64GB002-I/SS as a higher-memory alternative on the same 28-SSOP footprint.
推薦
LED Lighting Controller
The PIC24FV08KM102-I/SS suits multi-channel LED lighting controllers because its Capture/Compare/PWM modules directly drive LED FETs with hardware dead-time control, and the Configurable Logic Cell can implement hardware overcurrent shutdown paths without external glue. The wide VDD range allows direct operation from 5V USB-LED strips or 3.3V battery-powered fixtures. The 23 I/O pins are enough for an RGBW channel plus a rotary encoder and I2C sensor bus.

主要差異化特點
- Wider operating voltage range than the F subfamily sibling (對比PIC24F08KM102-I/SS)
- Lower unit cost and same package as the higher-memory USB-enabled sibling (對比PIC24FJ64GB002-I/SS)
- On-chip Configurable Logic Cell (CLC) for glue-logic replacement (對比PIC24FJ16GA002-I/SS)
設計說明
Decouple VDD (pin 20) and the secondary VSS (pin 19) with a 100 nF ceramic capacitor placed within 5 mm of the package, plus a bulk 4.7 uF-10 uF ceramic or tantalum at the regulator output. The PIC24FV08KM102-I/SS will operate from 2.0V to 5.5V, so a single TPS7A0220PDBVR LDO or direct Li-ion/3xAA connection is sufficient. Place the bulk capacitor first on the rail, then the 100 nF, to suppress high-frequency switching noise from the PWM and ADC references.
Configure the Configuration Words correctly: enable the watchdog timer for field-deployed designs, set the BOR (Brown-out Reset) voltage to match your supply tolerance, and choose the correct oscillator mode (internal FRC vs external crystal). Failure to lock the Configuration Words can leave the device in an undefined startup state on brown-out events. Also, leave MCLR (pin 1) pulled up to VDD through a 10 kohm resistor - leaving it floating can cause spurious resets in noisy environments.
Keep analog traces (ANx inputs, VREF+, VREF-) short and routed away from PWM and digital switching traces to minimize crosstalk on the 12-bit ADC. For mixed-signal designs, use a ground plane split between the analog ground island (under the VREF/ANx pins) and the digital ground, joined at a single point at the VSS pin (pin 19). If using the on-chip comparators for overcurrent protection, keep the comparator input traces short and bypass the C1IN+/C1IN- pins to ground with 100 pF ceramics.
For 28-SSOP hand-prototyping, use a fine-pitch (0.65 mm) SSOP breakout board or solder to an SOIC-to-DIP adapter. Reserve a 4-layer PCB with a dedicated ground plane for production; the SSOP thermal pad is not present on this package, so thermal management is not a concern at the 32 MHz / 16 MIPS operating point. Keep trace lengths to the OSCI/OSCO pins (9 and 10) under 5 mm to avoid oscillator startup failures with low-ESR crystals.
