PIC24FV08KM202-I/SO Overview
A microcontroller (MCU) is a single-chip computer that contains a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and a rich set of peripherals such as ADC, timers, communication ports, and I/O pins. The PIC24F family uses a 16-bit modified Harvard RISC architecture with 16-bit wide instructions and 24-bit wide data paths, sitting in the hierarchy (in-band interconnect) PIC24F -> PIC24 -> PIC -> 8-bit microcontroller -> embedded processor -> semiconductor. The XLP designation denotes nanoWatt technology for sleep currents below 100 nA in deep sleep modes.
Key specifications include 32 MHz MIPS performance, 8 KB Flash (2.75K x 24 instruction words), 2 KB SRAM, integrated 12-bit ADC up to 500 ksps, two 8-bit DACs, three op-amps, two analog comparators, three 16-bit Capture/Compare/PWM (CCP) modules, two UART, one SPI, one I²C, and a 25 mA source/sink per I/O capability. The Configurable Logic Cell allows hardware-level combinational and sequential logic without burning CPU cycles, useful for glue-logic replacement and event-driven signaling.
Typical applications include portable medical devices (blood glucose meters, pulse oximeters), battery-powered IoT sensor nodes, low-power LCD or segment displays, consumer remote controls, smart thermostats, and industrial 4-20 mA loop-powered transmitters. The wide operating voltage makes it compatible with both 3.3V digital ICs and legacy 5V analog front-ends.
When designing with this MCU, choose a supervisor/MCU pair that matches your real-time response needs; the 32 MHz core delivers 16 MIPS. For lowest sleep current, route unused pins as outputs and disable unused peripherals via PMD registers. The 28-SOIC package supports easy hand-soldering and breadboard prototyping.

Typical Applications
PIC24FV08KM202-I/SO is suitable for 7 applications: Portable Medical Devices (Blood Glucose Meters), Battery-Powered IoT Sensor Nodes, LCD Segment Display Controllers, Industrial 4-20 mA Loop-Powered Transmitters, Consumer Remote Controls (IR/RF), Smart Thermostats and HVAC Controllers, Automotive Body Electronics (LIN Nodes).
Portable Medical Devices (Blood Glucose Meters)
The PIC24FV08KM202-I/SO fits blood-glucose-meter designs because its 12-bit ADC at 500 ksps handles electrochemical-strip readout, while three on-chip op-amps condition the microamp-level sensor current without external analog ICs. The wide 2.0-5.5 V operating range supports both 3 V coin cells and USB-powered 5 V charging. Per the Microchip datasheet, nanoWatt XLP sleep currents below 100 nA extend battery life beyond 1000 measurements on a single CR2032. The CLC implements hardware-level strip-detection timing without waking the CPU.
Recommended
Battery-Powered IoT Sensor Nodes
The PIC24FV08KM202-I/SO is ideal for wireless sensor nodes because its deep-sleep current below 100 nA and 32 MHz active performance let the MCU sleep most of the time and wake briefly for sensor sampling. Per the Microchip datasheet, the on-chip 12-bit ADC samples thermistor or soil-moisture outputs directly, and dual UART/SPI interfaces connect to radio modules such as LoRa or Sub-GHz transceivers. The 8 KB Flash fits a typical Contiki-style or proprietary 6LoWPAN stack with room for application code.
Recommended
LCD Segment Display Controllers
The PIC24FV08KM202-I/SO drives segment LCDs directly via its integrated LCD driver peripheral, eliminating the need for an external driver IC and reducing BOM cost by 30-50%. The 2.0-5.5 V operating range supports both 3 V battery and 5 V mains-powered display products. According to the Microchip datasheet, the integrated op-amps and 8-bit DAC generate the V_bias reference voltage and contrast adjustment without external analog components. The CLC handles segment-multiplexing timing without CPU intervention.
Recommended
Industrial 4-20 mA Loop-Powered Transmitters
The PIC24FV08KM202-I/SO is well-suited for 4-20 mA loop-powered transmitters because it operates down to 2.0 V supply and includes integrated 12-bit ADC, op-amps, and DAC. Per the Microchip datasheet, the 2.0 V minimum Vrail makes it compatible with loop-surplus voltages typical of 12 V and 24 V industrial loops regulated by low-dropout linear regulators. The op-amps condition the sensor bridge, and the 8-bit DAC generates the 4 mA offset trim.
Recommended
Consumer Remote Controls (IR/RF)
The PIC24FV08KM202-I/SO is well-suited for IR/RF remote controls because of its nanoWatt XLP sleep current below 100 nA, which lets the MCU idle until a button-press interrupt wakes it within microseconds. Per the Microchip datasheet, the CCP modules generate precise carrier frequencies (36 kHz, 38 kHz, 40 kHz) for IR protocols without external timing ICs. The 28-SOIC footprint is hand-solderable for prototype builds, and the 25 mA I/O source/sink directly drives IR LEDs through current-limiting resistors.
Recommended
Smart Thermostats and HVAC Controllers
The PIC24FV08KM202-I/SO fits smart-thermostat designs because its analog-rich integration handles temperature-sensor signal conditioning without external components. The 12-bit ADC reads thermistor or RTD outputs directly, while on-chip op-amps implement the active low-pass filter for noise rejection. Per the Microchip datasheet, the wide 2.0-5.5 V range supports both battery-backed RTC and 24 VAC HVAC bus power after rectification. The CLC generates zero-crossing detection for TRIAC dimming of backlight displays.
Recommended
Automotive Body Electronics (LIN Nodes)
The PIC24FV08KM202-I/SO with its extended-temperature -E variant (PIC24FV08KM202-E/SO) suits LIN-bus automotive body electronics such as mirror controllers and seat-position nodes. Per the Microchip datasheet, the E variant operates over -40°C to +125°C and meets AEC-Q100 Grade 1 requirements. The integrated op-amps and ADC interface directly with LIN bus transceivers and motor-current sensors, eliminating external analog components.

Design Notes
The PIC24FV08KM202-I/SO supports nanoWatt XLP deep-sleep mode with currents below 100 nA. To achieve this in real designs, set all unused I/O pins to outputs driving low, disable unused peripherals via the PMD (Peripheral Module Disable) registers, and use the Deep Sleep mode (DSEN bit in DSCON) instead of regular Sleep. The on-chip voltage regulator (SVDD) and brown-out reset (BORVPO) must be enabled to ensure reliable wakeup. Wake-up time from Deep Sleep is typically 1 ms, dominated by the FRC oscillator stabilization.
Place decoupling capacitors (100 nF ceramic + 10 µF bulk) as close as possible to the VDD (pin 6) and VSS (pin 7) pins. Use a solid ground plane under the MCU with vias around the VSS pads for thermal dissipation. The 28-SOIC has 1.27 mm pitch; route signals with 0.15 mm trace width and 0.15 mm spacing to maintain signal integrity. For ADC accuracy, route analog signals (RA0-RA4, RA7-RA9) on the opposite side of digital signals and keep them short to minimize crosstalk.
Do not exceed the absolute maximum VDD of 6.5 V or the ESD rating of 2 kV HBM. The MCLR pin (pin 11) requires a 10 kΩ pull-up to VDD and a 100 nF capacitor to VSS for proper reset; leaving MCLR floating causes erratic behavior. The PGED1/PGEC1 pins (RB0/RB1) and PGED2/PGEC2 pins (RB6/RB7) must not be assigned to other functions unless in-circuit programming is disabled. Ensure the configuration bits are programmed to enable the appropriate oscillator mode and watchdog timer.
When using the 12-bit ADC, place a 10 nF capacitor on each analog input pin (Ra0-RA4, Ra7-Ra9) close to the MCU to filter RF noise. Enable the ADC's hardware averaging feature for sensor readings, and use a low-impedance source (< 10 kΩ) to drive the ADC inputs for full 500 ksps throughput. The on-chip op-amps should be configured in unity-gain buffer mode when driving the ADC directly to minimize ADC input leakage. See Microchip application note AN2699 for ADC design guidelines.
