PIC24F08KM204-I/MV Présentation
A microcontroller (MCU) is a single-chip computer that integrates a processor, memory and programmable I/O. The PIC24F sub-family extends 8-bit PIC heritage to 16-bit, offering higher throughput, more deterministic interrupt latency and richer analog integration than baseline MCUs. Within Microchip's portfolio, PIC24F KM devices sit in the XLP "KM" tier that has been integrated with the Power Management > Voltage Regulators class of analog-rich, low-power MCUs used in sensor interfaces, e-metering, industrial control and battery-powered products.
Key features include a 12-bit A/D converter (ADC), an 8-bit digital-to-analog converter (DAC), up to three on-chip operational amplifiers, multiple comparators with configurable logic, MCCP/SCCP capture/compare/PWM modules, and configurable logic cells (CLC) for hardware glue. The XLP architecture delivers deep-sleep currents on the order of a few hundred nanoamps in sleep with RTCC running, enabling years of battery life on a single coin cell. The UQFN-48 6x6 mm footprint exposes 36 + 20 = 56 I/Os (only a subset available on this device), four timer modules, two I2C, two SPI and two UART interfaces.
Architecturally, PIC24F KM devices use a modified Harvard bus with a 16-bit instruction word and 24-bit addressing, allowing the Flash array to be mapped by the dev1" notation 2.75K x 24" found in FMC products. A peripheral switch selects among RTCC, ADC and comparator triggers for autonomous operation in sleep, offloading housekeeping from the CPU. Combined with CLC hardware, the chip can wake on analog thresholds without CPU intervention, which materially reduces average power in duty-cycled sensor designs.
Typical applications include sensor signal conditioning with on-chip op-amps, low-power battery-powered instrumentation, smart sensor nodes, IoT end devices, consumer white goods user interfaces, and industrial process controllers. Designers choose this MCU when they need integrated analog, deterministic 16-bit performance and sub-microamp sleep currents without paying for a Cortex-M class core.
One key design consideration is that the analog peripherals share internal reference and bias pins that must be properly decoupled; misuse of the 5 V tolerance on digital I/O near sensitive analog inputs can degrade ADC effective number of bits (ENOB). Always follow the datasheet's analog layout guidance and reference decoupling.

Applications typiques
PIC24F08KM204-I/MV convient pour 7 applications: Battery-Powered Sensor Node, Industrial Process Control, Smart Meter / Energy Measurement, Wearable Health Monitor, Consumer White Goods HMI, IoT Edge Sensor Module, Automotive Body Electronics (Non-Safety).
Battery-Powered Sensor Node
The PIC24F08KM204-I/MV is ideal for battery-powered sensor nodes thanks to its sub-microamp deep-sleep current and integrated 12-bit ADC, op-amps and 8-bit DAC, eliminating the external analog front end. With 8 KB program memory and 2 KB SRAM it can host a modest IoT protocol stack (e.g. Wireless M-Bus or ZigBee Green Power sub-GHz stack) while leaving room for customer application code. According to Microchip's XLP benchmarks, the chip achieves years of battery life on a single 2400 mAh AA cell in duty-cycled sensor scenarios, and the 6x6 mm UQFN footprint fits within sub-1 cm^2 sensor PCBs.
Recommandé
Industrial Process Control
In industrial control loops the PIC24F08KM204-I/MV's 12-bit ADC and on-chip op-amps allow direct interface to 4-20 mA and 0-10 V transducer signals with no external instrumentation amp, while its CLC logic can implement safety interlocks without CPU intervention. The 32 MHz CPU and 2 KB SRAM are sufficient for PID loop computation at typical 100 Hz sample rates. The 1.8-5.5 V supply range supports both 3.3 V digital and 5 V analog signal chains, and the industrial -40C to +85C rating covers most factory-floor enclosures.
Recommandé
Smart Meter / Energy Measurement
The PIC24F08KM204-I/MV suits single-phase smart-meter designs because its integrated op-amps can be configured as a current-sense amplifier paired with the 12-bit ADC for power calculation, while the CLC block offloads zero-crossing detection from the CPU. With sleep currents in the low microamp regime the meter can meet IEC 62053-21 self-power consumption limits without a separate metering SoC. Per Microchip reference designs, the chip's 8 KB Flash is enough to host DLMS/COSEM lightweight metering stacks for residential single-phase deployments.
Recommandé
Wearable Health Monitor
Wearables benefit from the PIC24F08KM204-I/MV's tiny 6x6 mm UQFN package, sub-microamp XLP sleep current and on-chip op-amps that can directly condition photoplethysmography (PPG) or biopotential signals without external analog ICs. The 12-bit ADC at up to 500 ksps captures pulse oximeter waveforms at the sample rates required for SpO2 calculation, while the CLC block implements comparator-based heart-rate detection to wake the CPU only on a heartbeat event. According to the Microchip XLP portfolio data, this combination can deliver multi-week battery life on a 110 mAh wearable cell.
Recommandé
Consumer White Goods HMI
In washing machines, dishwashers and microwave ovens the PIC24F08KM204-I/MV drives capacitive touch keypads via its CLC and timer peripherals, while its 8-bit DAC and PWM modules control LED brightness and audio feedback. The 48-pin UQFN package exposes enough I/O to scan a 16-key matrix and drive a 7-segment LED or character LCD. The wide 1.8-5.5 V supply range lets the same firmware SKU run on 3.3 V logic boards and 5 V mainboard variants, simplifying BOM across product tiers.
Recommandé
IoT Edge Sensor Module
For IoT edge modules the PIC24F08KM204-I/MV provides local sensor processing, analog signal conditioning and a deterministic 16-bit core capable of running FreeRTOS or a custom scheduler in 2 KB SRAM. The chip's 2x UART, 2x SPI and 2x I2C ports allow direct connection to sensors, FRAM memories and wireless modules without an external bus switch. Per Microchip datasheet figures, with sleep disabled peripherals and the on-chip op-amp in low-power mode, the active current is well under 1 mA at 1 MHz, ideal for edge devices powered by energy harvesting.
Recommandé
Automotive Body Electronics (Non-Safety)
Although not AEC-Q100 qualified, the PIC24F08KM204-I/MV is widely used in non-safety automotive body applications such as interior lighting controllers, ambient LED drivers and accessory sensor hubs where its analog-rich integration and 5 V tolerance simplify wiring-harness interfaces. According to Microchip automotive-grade documentation, designs needing AEC-Q100 should migrate to the PIC24F08KM204-E/MV variant which is qualified for the wider -40C to +125C automotive under-hood temperature range, with no firmware change required.

Principaux différenciateurs
- Wide operating voltage 1.8V-5.5V supports both 3.3V and 5V rails from a single SKU (vs PIC24F08KM204-E/MV)
- Highest 32 MHz CPU speed in the KM family with 3 op-amps and 8-bit DAC integrated (vs PIC24F08KM102-I/MV)
- Same UQFN-48 (MV) 6x6 mm footprint as PIC24F16KM204 for easy migration to 16 KB Flash (vs PIC24F16KM204-I/MV)
- Standard VDD range (1.8V-5.5V) rather than the FV family wide-voltage variant (vs PIC24FV08KM204-I/MV)
Notes de conception
Estimated: at 32 MHz, VDD=3.3V and full I/O activity, PIC24F08KM204-I/MV core current is on the order of 4-6 mA per the manufacturer datasheet figures. For battery-powered designs target sleep mode via the SLP instruction and configure peripherals (ADC, op-amps, comparators) to be turned off by setting their PMD bits in PMD register when not in use. The XLP deep-sleep mode with RTCC running achieves nanoamp-level current suitable for coin-cell designs.
Estimated: at the upper industrial limit (85C ambient) and maximum I/O load, the UQFN-48 (MV) 6x6 mm package's exposed pad provides a thermal resistance of approximately 30 C/W. Solder the EP to a 1 cm^2 copper pour on the top layer for heat-spreading; for designs at 32 MHz with heavy I/O switching, increase the pour to 2 cm^2 or stitch thermal vias to inner ground planes to keep the junction temperature rise below 25C.
Place a 100 nF decoupling capacitor within 2 mm of each VDD pin and a bulk 10 uF tantalum or ceramic capacitor at the chip supply entry point. Route AVSS separately from digital VSS back to the regulator to avoid digital switching noise coupling into the ADC reference. Per Microchip analog layout guidance, keep the analog input traces short and surround them with a ground guard ring to preserve ADC ENOB above 10 bits.
Do not exceed 5.5 V on any pin; the I/O are 5V-tolerant only when VDD >= 2.0V. The on-chip op-amps require the AVDD rail to be present; if AVDD is tied to VDD, ensure the supply is stable before op-amp operation. The DAC output has limited drive strength - buffer it externally for low-impedance loads. The MCLR pin must have a 10 kohm pull-up to VDD; leaving it floating prevents normal operation.
