PIC24FV08KM202-I/SS Overview
A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture RISC processor designed by Microchip, sitting within the broader MCU > microcontroller > embedded processor > semiconductor hierarchy. The 16-bit PIC24F family targets low-power, analog-rich embedded designs and is widely used in consumer, industrial, and IoT products where deterministic behavior, integrated peripherals, and low sleep current matter more than raw MHz.
Key features include a 12-bit A/D converter with up to 16 channels, two 8-bit DACs, two operational amplifiers, two analog comparators, three op-amp/comparator/timer modules, and Microchip's Configurable Logic Cell (CLC) for hardware-level glue logic without external gates. Communication peripherals cover I2C, SPI, UART, and CCP/CCP capture/compare/PWM modules for motor and lighting control. The 'FV' prefix specifically guarantees 5V-tolerant operation alongside 3.3V systems, enabling designs that mix legacy 5V analog with modern 3.3V logic.
Typical applications include low-power sensor nodes, e-metering, battery-powered medical devices, LED lighting controllers, HVAC control panels, and small appliance human-machine interfaces. The XLP sleep currents in the nanoamp range extend battery life for products that wake infrequently and need years of standby operation.
When designing with this part, reserve at least two GPIO for SWD-style programming/debug if you plan to use ICSP, and verify the FV voltage tolerance if your rails exceed 3.6V. The internal 7.37MHz FRC oscillator with PLL gives you a free 32MHz system clock without any external crystal, saving BOM cost in cost-sensitive designs.

Typical Applications
PIC24FV08KM202-I/SS is suitable for 6 applications: Battery-Powered IoT Sensor Node, LED Lighting and Luminaire Controller, Industrial HVAC Control Panel, Portable Medical Monitor, Consumer Appliance HMI Board, Smart Energy Meter / Sub-Meter.
Battery-Powered IoT Sensor Node
The PIC24FV08KM202-I/SS fits battery-powered IoT sensor nodes because its XLP Deep Sleep current sits around 20-50 nA with the RTCC running, while the 2.0-5.5V FV range supports single-cell Li-ion, two-AA alkaline, and even 5V USB-supplied charging topologies. The 12-bit ADC with 16 channels can read multiple sensors (temperature, humidity, light) directly, eliminating external analog front-end parts. The CLC block lets the MCU wake on a comparator edge without CPU intervention, so the part can spend >99% of its life asleep. Compared with Cortex-M0+ alternatives at similar prices, the KM2 part often wins on integrated op-amp count and 5V tolerance, while losing on raw active-mode MIPS.
Recommended
LED Lighting and Luminaire Controller
The PIC24FV08KM202-I/SS is well suited to LED lighting controllers because the 2x 8-bit DACs and 2x on-chip op-amps can drive constant-current sinks or color-mixing circuits without external amplifiers. The MCCP/SCCP PWM modules deliver flexible dimming frequencies (up to 32MHz time base), and the CLC block can implement hardware-level thermal foldback or color-blending logic. The 5V FV tolerance lets the part directly drive 5V analog reference strings for tunable-white or RGBW fixtures. Compared with bare 8-bit MCUs at the same price, the KM2 part offers more PWM resolution and integrated analog, while costing less than STM32-based lighting controllers.
Recommended
Industrial HVAC Control Panel
In industrial HVAC control panels, the PIC24FV08KM202-I/SS brings 5V analog tolerance for legacy 0-10V actuator interfaces and 23 GPIO for keypad, LCD, relay, and triac control lines. The two on-chip op-amps can condition thermistor or pressure-transducer signals directly into the 12-bit ADC. UARTs and SPIs handle Modbus, BACnet, or proprietary panel-bus links. The -40C to +85C industrial grade and 5V supply range cover rooftop unit, indoor air-handler, and thermostat environments. Compared with ARM Cortex-M0 designs at similar cost, the KM2 part offers more integrated analog and lower sleep current, at the expense of active MIPS.
Recommended
Portable Medical Monitor
The PIC24FV08KM202-I/SS is a good fit for portable medical monitors (pulse oximeters, glucose meters, INR testers) where XLP sleep current and integrated analog matter most. The 12-bit ADC can directly digitize photodiode or electrochemical-sensor signals with 5V op-amp conditioning, while the on-chip DAC drives a buzzer or LED reference. CLC logic can debounce buttons or generate fault flags without CPU wakeup, extending coin-cell battery life. The 5V FV tolerance simplifies designs that must drive legacy LCD contrast pumps. Compared with MSP430 alternatives, the KM2 part offers more GPIO and a richer analog block, but somewhat higher active-mode current.
Recommended
Consumer Appliance HMI Board
For consumer appliance HMI boards (coffee machines, washing machines, microwave ovens), the PIC24FV08KM202-I/SS offers 5V tolerant I/O to drive triac drivers, seven-segment LEDs, and buzzer transducers directly without level shifters. The 23 GPIO can multiplex a keypad, a TFT or character LCD, status LEDs, and rotary encoder, while the 2x UART enables Bluetooth/Wi-Fi module control for smart-appliance variants. CLC logic handles button debounce and triac zero-cross detection in hardware, offloading the CPU. Compared with Cortex-M0 parts at similar cost, the KM2 offers more analog integration and 5V tolerance; trade-off is lower active-mode MIPS.
Recommended
Smart Energy Meter / Sub-Meter
The PIC24FV08KM202-I/SS is well suited to smart electricity sub-meters and e-metering front-ends because the 12-bit ADC plus 2 on-chip op-amps can directly digitize shunt or current-transformer signals. The 5V FV tolerance simplifies current-sense amplifier rails, and the CLC can implement tamper-detection logic in hardware without firmware overhead. UART, SPI, and I2C connect to wireless M-Bus, LoRa, or Wi-Fi modules for AMI backhaul. Deep-sleep nanoamp currents enable battery-backed tamper logging. Compared with dedicated metrology ICs, the KM2 part is more general-purpose but lower cost and easier to integrate.

Key Differentiators
- 5V-tolerant FV supply range (vs PIC24FJ64GA002-I/SS)
- Higher temperature grade available (vs PIC24FV08KM202-I/SS)
- Lower unit cost than larger-memory siblings (vs PIC24FJ64GB202-I/SS)
Design Notes
The PIC24FV08KM202-I/SS supports 2.0V to 5.5V on VDD. Place a 10uF bulk plus 0.1uF decoupling capacitor within 5mm of each VDD pin (pins 13 and 28). For battery applications, MCP1700 or MCP1702 LDOs are recommended low-Iq partners. Estimated: with all peripherals off in Deep Sleep, Vdd=3.0V, the part draws ~20-50 nA, so a 1000mAh Li-ion cell could power a wake-every-minute sensor for years.
Keep the 28-SSOP's exposed-pad (if present) soldered to a copper island for thermal relief. Route ICSP lines (PGD1/PGC1, pins 4 and 5) directly to a 5-pin header so a PICkit or Snap can program the board in-circuit without removing the MCU. Per Microchip layout notes, keep crystal traces short (under 5mm) and guard them with a ground ring if accuracy is critical.
Do not exceed 5.5V on any pin including MCLR - even transient overshoot can damage the FV-tolerant input. The /I suffix is industrial (-40C to +85C); for hotter or colder environments, choose PIC24FV08KM202-E/SS instead. Finally, MCLR must be pulled high through a 10k resistor; leaving it floating causes spurious resets. Per Microchip errata, the first production runs of the KM2 family had a specific ADC issue at 5V operation that is fixed in current revisions - always check the datasheet errata sheet before committing to 5V designs.
The on-chip op-amps and comparators share analog pins with digital I/O. To prevent digital noise coupling into analog measurements, configure ADC channels in software to disable unused digital input buffers (per Microchip ADC AN application note). Place analog signals on PORTA pins and digital signals on PORTB/PORTC where possible. A small RC filter (100 ohm + 100pF) on the analog inputs often improves ADC noise performance in motor-control boards.
Compliance Information
