PIC24FV08KM202T-I/ML Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (FLASH/ROM), data memory (RAM), and a rich set of on-chip peripherals such as timers, communication interfaces, ADCs, and DACs. The PIC24F family sits in the 16-bit MCU segment of Microchip's portfolio, above the 8-bit PIC16/PIC18 lines and below the 32-bit PIC32 line. The "XLP" (eXtreme Low Power) designation indicates the device targets battery-powered and energy-harvesting applications with sub-uA sleep currents. PIC24F devices generally operate from 1.8 V to 5.5 V (the FV variant retains 5 V tolerance and adds a wider flash endurance window), making them well-suited to coin-cell, 2xAA, and 3.3 V/5 V mixed-rail systems.
Key differentiating specifications of this part include integrated 12-bit ADC, an 8-bit DAC, on-chip operational amplifiers, and a Configurable Logic Cell (CLC) - features rarely bundled at this pin count. Communication peripherals include I2C, SPI, UART/USART, LIN, and IrDA. The 32 MHz CPU delivers up to 16 MIPS, sufficient for real-time control loops, sensor fusion, and basic signal processing.
Architecturally, the PIC24FV08KM202 uses a 16-bit modified Harvard core with a 24-bit instruction word, allowing single-cycle MAC operations and deterministic interrupt latency. The wide 1.8-5.5 V supply range, eXtreme Low Power modes (sleep, deep sleep, RTCC), and integrated analog make this device well suited for portable instrumentation, sensor hubs, and consumer electronics.
Typical applications include low-power IoT sensor nodes, battery-powered medical devices (glucose meters, pulse oximeters), LIN slave nodes in automotive body electronics, e-metering and smart thermostats, and small industrial HMI panels. The integrated op-amp + DAC chain enables direct photodiode or bridge-sensor interfaces without external analog ICs.
When designing with this part, pay attention to the 28-QFN PCB footprint and exposed pad layout - the e-pad must be soldered to a sufficient ground copper area (typically >= 1 square inch) to meet the datasheet's thermal resistance spec. Decoupling capacitors should be placed within 3 mm of the VDD/VSS pins.

Typical Applications
PIC24FV08KM202T-I/ML is suitable for 7 applications: Battery-Powered IoT Sensor Node, Portable Medical Device Controller, Automotive LIN Slave Node, Smart Thermostat / HVAC Controller, E-Metering / Energy Monitor, Industrial Sensor Hub / 4-20 mA Loop Transmitter, Consumer Remote Control / IR Transceiver.
Battery-Powered IoT Sensor Node
The PIC24FV08KM202T-I/ML is well suited for low-power IoT sensor nodes thanks to its XLP (eXtreme Low Power) architecture achieving sub-uA sleep current and integrated 12-bit ADC plus op-amps that eliminate external analog ICs. Operating from 1.8 V to 5.5 V lets it run directly from a single Li-ion cell or 2xAA battery pack. The 32 MHz CPU delivers 16 MIPS, sufficient for periodic sensor reads, simple filtering, and transmit-side protocol stacks (BLE/LPWAN beacons). Place the part on the lowest-quiet PCB layer near the battery with proper e-pad soldering to meet the datasheet's thermal spec.
Recommended
Portable Medical Device Controller
For portable medical devices like glucose meters, pulse oximeters, and Bluetooth-enabled thermometers, the PIC24FV08KM202T-I/ML provides deterministic 16-bit control with on-chip DAC for sensor excitation and op-amps for signal conditioning. The integrated analog chain reduces BOM cost and PCB area - critical for small-form-factor medical designs. The 32 MHz CPU handles real-time sensor sampling while the XLP sleep modes extend battery life to weeks or months. The device's 1.8-5.5 V range lets it share a single 3 V coin cell with peripheral sensors without boost converters.
Recommended
Automotive LIN Slave Node
In automotive body-electronics LIN slave applications (window switches, mirror controls, seat position sensors), the PIC24FV08KM202T-I/ML provides an integrated LIN bus interface and 12-bit ADC for direct sensor read, eliminating the need for an external LIN transceiver in cost-sensitive nodes. The 1.8-5.5 V supply range tolerates automotive 12 V rail transients when paired with a regulator. For underhood or harsher environments requiring AEC-Q100, the PIC24FV family offers related qualified variants - though the KM202T-I/ML itself is industrial-grade and suitable for cabin-mounted LIN nodes.
Recommended
Smart Thermostat / HVAC Controller
Smart thermostat and HVAC control designs benefit from the PIC24FV08KM202T-I/ML's integrated analog chain - the 12-bit ADC reads thermistor bridges, the 8-bit DAC sets reference voltages for comparator thresholds, and the op-amps condition the sensor signals. The CLC (Configurable Logic Cell) implements custom glue logic without external gates. UART/I2C peripherals connect to Wi-Fi modules and display drivers, while the 28-QFN package fits inside small wall-mount enclosures. The XLP sleep current keeps idle display/sensor power below 50 uW.
Recommended
E-Metering / Energy Monitor
Single-phase e-metering and energy-monitoring front-end designs leverage the PIC24FV08KM202T-I/ML's 12-bit ADC, integrated op-amps for current-shunt amplification, and Configurable Logic Cell for power-factor calculation. The 32 MHz CPU computes RMS values, harmonics, and accumulated kWh in real time while staying within the device's power envelope. Communication via UART/IrDA reports consumption to remote displays or PLCs. The 1.8-5.5 V range lets the device run from a single 3.3 V LDO downstream of the AC mains isolation barrier.
Recommended
Industrial Sensor Hub / 4-20 mA Loop Transmitter
For industrial sensor hubs and 4-20 mA loop transmitters, the PIC24FV08KM202T-I/ML provides the 12-bit ADC to digitize field sensors (pressure, flow, level), the integrated DAC to drive the 4-20 mA loop, and the op-amp to buffer the output. The CLC implements proprietary sensor compensation without external logic. UART/SPI peripherals carry Modbus or wireless uplinks. The industrial -40 C to +85 C temperature grade is adequate for cabinet-mounted industrial environments, while the exposed-pad QFN enables compact DIN-rail module designs.
Recommended
Consumer Remote Control / IR Transceiver
Consumer IR remote controls and bidirectional IR transceivers benefit from the PIC24FV08KM202T-I/ML's integrated IrDA peripheral, low-power XLP modes, and small 28-QFN package. The 32 MHz CPU runs IrDA stack protocols, while sleep current below 1 uA extends coin-cell battery life. The 12-bit ADC reads button matrices or capacitive sense channels, and the Configurable Logic Cell implements custom IR encoding patterns. The wide 1.8-5.5 V supply range accepts single-cell Li-ion or 2xAAA alkaline sources.

Key Differentiators
- Highest-density analog integration in PIC24F family at this pin count (vs PIC24FV08KM202-I/ML)
- Extended flash endurance for write-intensive applications (vs PIC24FJ08KM202)
- XLP architecture achieves lowest sleep current in PIC24F line (vs PIC24F16KA102 (older 16-bit PIC))
Design Notes
The 28-QFN package relies on the exposed thermal pad (e-pad) on the underside for heat dissipation. Per the datasheet, the e-pad must be soldered to a copper pour on the top layer (typically >= 1 square inch) and thermally connected via an array of thermal vias to inner ground planes. Failing to solder the e-pad will increase junction-to-ambient thermal resistance significantly and risk thermal shutdown under sustained loads. Estimated: with 1 square inch copper pour on a 4-layer JEDEC board, theta_JA is approximately 28 C/W.
Place decoupling capacitors (100 nF ceramic + 4.7 uF bulk) within 3 mm of the VDD/VSS pins to minimize supply noise on the analog rail. The 12-bit ADC requires a clean AVDD supply - use a ferrite bead or LC filter to isolate AVDD from the digital VDD if the board has switching regulators nearby. Keep the analog input traces short and avoid running them parallel to high-frequency digital lines to preserve ADC SNR.
Do not exceed the absolute maximum supply of 5.5 V on VDD - transients above this can damage the internal flash memory. The PPS (Peripheral Pin Select) module must be configured in firmware before using remappable peripherals (UART, SPI, etc.) - leaving default assignments will leave pins stuck in GPIO mode. When migrating from PIC24FJ to PIC24FV, verify that your firmware does not depend on older device errata workarounds that may no longer apply to the FV silicon revision.
Route the crystal oscillator traces (OSCI/OSCO, pins 27-28) as short as possible, symmetrically, and surrounded by a ground pour to minimize EMI coupling. Use guard traces if the crystal traces run near analog inputs. For USB/LIN/CAN-style differential signaling, route the pair with 100-ohm characteristic impedance and matched lengths within 50 mils. Place the programming/debug connector near the IC with a direct, short trace to MCLR/PGED/PGEC pins to ensure reliable ICSPM programming.
