PIC24F08KM202-E/SO Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash/RAM), and programmable peripherals into one package. The PIC24F08KM202 sits within the broader hierarchy of PIC24F -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. Within Microchip's nanoWatt XLP™ portfolio it is positioned as a low-power, mixed-signal device, combining digital control with on-board analog blocks so designers can shrink board area and BOM cost on battery-powered products.
Key features include 8 KB Flash, 2 KB SRAM, a 12-bit A/D converter with multiple input channels, a 8-bit DAC, up to three on-chip op amps, configurable logic cells (CLC), multiple Capture/Compare/PWM modules, and serial interfaces including I2C, SPI, UART/USART, IrDA, and LINbus. The integrated peripheral set means designers often eliminate external ADC, DAC, and op-amp ICs, reducing both PCB footprint and quiescent current budget.
The PIC24F08KM202 uses Microchip's modified Harvard architecture with a 16-bit data path and a 24-bit instruction word, executed through a pipelined RISC core. The nanoWatt XLP sleep modes typically drop consumption into the sub-µA range, allowing multi-year battery life on a single coin cell for sensor and metering duties. On-chip FRC and LPRC oscillators plus a PLL provide flexible timing without external crystals in many designs.
Typical applications include portable medical and consumer devices, e-metering and energy-harvesting nodes, automotive body and LIN sub-net nodes, IoT sensor end-points, and industrial sensor interfaces. The -E extended temperature grade is required wherever the operating environment exceeds +85 °C. When designing with this part, verify your compiler choice (XC16) supports the specific silicon revision and budget enough decoupling capacitance close to the AVDD/VDD pins for clean ADC sampling.

Typical Applications
PIC24F08KM202-E/SO is suitable for 6 applications: Battery-Powered IoT Sensor End-Points, Automotive LIN Bus Body Electronics, Portable Medical and Health Monitoring Devices, Industrial Sensor Interface and Process Monitoring, Smart Energy Metering and Energy Harvesting Nodes, Consumer Appliance User Interface and Control Boards.
Battery-Powered IoT Sensor End-Points
The PIC24F08KM202-E/SO suits battery-powered IoT sensor nodes because its nanoWatt XLP™ sleep modes typically draw sub-µA, allowing multi-year life on a single coin cell. The integrated 12-bit ADC, 8-bit DAC, and three on-chip op amps condition thermistor, photodiode, and Wheatstone-bridge signals directly, eliminating external analog ICs. Its 1.8 V to 3.6 V operating range matches Li-ion, 2xAA, and coin-cell chemistries without an additional LDO, simplifying the power tree and reducing BOM cost in space-constrained end-point designs.
Recommended
Automotive LIN Bus Body Electronics
With LINbus-capable EUSART, -E/+125 °C temperature grade, and on-chip 12-bit ADC, the PIC24F08KM202-E/SO is a strong fit for automotive body-control sub-nets such as door modules, seat controllers, mirror adjusters, and rain/light sensors. The on-chip op amps directly buffer automotive sensor outputs (Hall, thermistor) before ADC sampling, reducing analog BOM. Its wide 28-SOIC footprint simplifies hand-soldering during service and supports high-vibration automotive environments where smaller QFN packages can fail.
Recommended
Portable Medical and Health Monitoring Devices
The PIC24F08KM202-E/SO powers portable medical devices such as pulse oximeters, glucose meters, and wearable health monitors where its 16-bit core, low power, and integrated 12-bit ADC provide accurate biosignal acquisition. The on-chip operational amplifiers can directly amplify photodiode or biopotential electrode signals, eliminating an external analog front-end IC. With nanoWatt XLP™ modes drawing sub-µA in sleep, the device extends battery life across weeks of wear time, a critical factor in patient adherence.
Recommended
Industrial Sensor Interface and Process Monitoring
In industrial sensor interfaces the PIC24F08KM202-E/SO converts 4-20 mA, 0-10 V, and RTD/thermocouple inputs to digital readings via its 12-bit ADC and integrated op-amp signal conditioning. The -40 °C to +125 °C extended temperature grade supports cabinet-mounted and field-edge installations, while UART/SPI/I2C enable seamless uplink to a host PLC or industrial gateway. The on-chip configurable logic cells (CLC) implement custom glue logic such as frequency-to-voltage conversion without an external CPLD.
Recommended
Smart Energy Metering and Energy Harvesting Nodes
For e-metering and energy-harvesting end nodes, the PIC24F08KM202-E/SO's sub-µA XLP sleep current and 1.8 V minimum operation maximize harvested energy utilization, while its 8-bit DAC and op amps drive proportional-integral control loops in switching converters. Its 8 KB Flash fits standard metering firmware including tamper logging, LCD driving, and one-shot calibration, and the device's LIN/EUSART simplifies integration with meter-bus and wireless M-Bus extensions.
Recommended
Consumer Appliance User Interface and Control Boards
Consumer appliances such as coffee machines, air purifiers, and washing machines benefit from the PIC24F08KM202-E/SO's combination of 12-bit ADC for sensor inputs (temperature, humidity, flow), PWM outputs for motor/valve control, and UART/I2C for display and connectivity modules. The on-chip CLC and op amps reduce external glue logic, enabling compact BOMs in cost-sensitive white goods. The wide 28-SOIC package is easy to hand-prototype, helping design teams iterate quickly on next-generation UI boards.

Key Differentiators
- Highest analog integration in the PIC24F 28-SOIC family (vs PIC24F08KL201-I/SO)
- Doubles Flash while staying pin-compatible (vs PIC24F08KM202 (this) vs PIC24F16KM202-E/SO)
- Extended -40 to +125 °C temperature grade (vs PIC24F08KM102-I/SO)
Design Notes
Estimated: at 32 MHz active and VDD 3.3 V, the PIC24F08KM202-E/SO draws roughly 8 mA typical. In Sleep mode with the on-chip peripherals off it drops to sub-µA. Place a 100 nF ceramic decoupling capacitor as close as possible to each VDD/VSS pair (pins 8, 15) and to AVDD/AVSS (pins 27, 28). For ADC accuracy, drive AVDD from a separate filtered LDO rail if the digital supply is noisy.
Keep the crystal or external clock traces (OSC1, OSCC2) short - ideally under 5 mm - and guard them with a ground pour to minimize EMI coupling. Route PGD/PGC (RB6/RB7) away from analog inputs and PWM outputs to reduce noise pickup during in-circuit programming. Expose the thermal pad area beneath the SOIC to a continuous ground pour for thermal spreading during heavy PWM/CCP loads.
For ADC measurements to achieve 12-bit accuracy, the source impedance driving any analog input pin must be less than approximately 5 kohm. Add an external op-amp buffer if the sensor impedance is higher. Acquire multiple ADC samples and average them in software; PIC24F KM parts support hardware accumulation in the ADC1 buffer to offload this work. Always recalibrate ADC offset/gain per the device errata sheet for your silicon revision.
Do not rely on the on-chip 8-bit DAC for AC audio signals - it is intended for low-bandwidth DC set-points (sensor excitation, comparator thresholds). Do not exceed the Absolute Maximum VDD of 4.0 V; the KM202 is not 5 V tolerant on any I/O. Finally, ensure the MCLR pull-up is strong (typically 10 kohm to VDD) because the device's BOR may not assert reliably with a weak MCLR bias in noisy industrial environments.
Compliance Information
RoHS and REACH compliant per Microchip product page; lead-free and halogen-free per PIC24F KM family datasheet (DS39997). Not AEC-Q100 qualified - choose PIC24F08KM202-E/SO only for non-automotive safety-critical applications or LIN body-electronics where AEC-Q100 is not required.
