PIC24F08KM102T-I/ML Descripción general
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, peripheral I/O and often analog blocks. The PIC24F family uses Microchip's 16-bit modified-Harvard architecture with a 32MHz instruction pipeline, giving substantially higher MIPS/Watt than 8-bit PIC MCUs while retaining the deterministic interrupt model that PIC is known for. Within the broader microcontroller taxonomy, the PIC24F series sits between 8-bit PIC16/PIC18 and 32-bit PIC32MX families, optimized for low-power and mixed-signal embedded designs.
Key features of the PIC24F08KM102 include 12-bit ADC, comparators, CLC (Configurable Logic Cell), MCCP/SCCP timer modules, and support for both 3V and 5V applications. It also offers eXtreme Low Power (XLP) sleep currents in the nanoamp range, making it suitable for battery-powered products. The device integrates RTCC, multiple UART/SPI/I2C peripherals, and up to 23 I/O pins.
Technically, the PIC24F08KM102T-I/ML uses a 16-bit RISC architecture with 32MHz internal oscillator, single-cycle 16x16 hardware multiply, and a 7-channel 12-bit ADC at 100k samples/s. The 28-QFN package includes an exposed pad for thermal dissipation and ground reference, critical for ADC noise performance in mixed-signal boards.
Typical applications include portable medical devices, IoT sensor nodes, consumer electronics, motor control peripherals, low-power wireless sensor platforms, and industrial sensing modules. The 8KB Flash tier of the KM family targets cost-down designs that need 16-bit performance but not the 16KB/32KB Flash of higher-tier variants.
When designing with this part, remember the 28-QFN (6x6) package requires careful PCB layout because the exposed pad is the main thermal and ground path. Use adequate decoupling (100nF + 1uF) near the VDD pins, and program the CONFIG register early in firmware to lock the oscillator and watchdog behavior before any peripheral initialization.

Aplicaciones típicas
PIC24F08KM102T-I/ML es adecuado para 7 aplicacións: Battery-Operated IoT Sensor Node, Portable Medical Monitoring Device, Consumer Remote Control / HMI, Industrial Sensor Transmitter, Low-Power Wireless Sensor Platform, LED Lighting Controller, Motor Control Peripheral (Small BLDC/Fan).
Battery-Operated IoT Sensor Node
The PIC24F08KM102T-I/ML fits battery-operated IoT sensor nodes because of its nanoWatt XLP sleep currents in the sub-nanoamp range and 16-bit CPU throughput at 32MHz. Its 12-bit ADC handles analog sensor signals with 100k samples/s throughput, while CLC provides glue logic without external gates. Placed on a coin-cell powered PCB with a 32.768kHz crystal for RTCC, the MCU spends most of its life in sleep and wakes only to read sensors and transmit, extending battery life to multiple years. Compared to an 8-bit PIC18, the 16-bit core executes sensor processing algorithms faster, allowing more aggressive duty cycling.
Recomendado
Portable Medical Monitoring Device
The PIC24F08KM102T-I/ML fits portable medical monitoring devices because its 16-bit PIC24F core delivers deterministic real-time response for biosignal acquisition while XLP nanoWatt technology keeps average current draw low. The 12-bit ADC captures ECG, pulse oximetry or temperature signals with sufficient resolution, and CLC offloads simple logic operations for power-saving event detection. The 28-QFP expands to 28-QFN ML on a small medical PCB, with the exposed pad providing thermal stability for analog reference circuits. Designers leverage MCCP/SCCP for precise PWM-driven LED pulse generation in optical SpO2 measurement.
Recomendado
Consumer Remote Control / HMI
The PIC24F08KM102T-I/ML suits consumer remote control and human-machine interface products because its 32MHz 16-bit core handles IR protocol encoding/decoding and capacitive touch sensing in real time. The CLC block replaces external glue logic that traditional remote designs need, while the 12-bit ADC reads potentiometers and battery voltage. The 28-QFN (6x6 mm) ML package fits inside thin remote enclosures. XLP sleep currents in the sub-uA range enable multi-year battery life from two AAA cells, and the 8KB Flash accommodates larger IR code libraries than 8-bit PIC16 alternatives.
Recomendado
Industrial Sensor Transmitter
The PIC24F08KM102T-I/ML suits industrial sensor transmitters because of its industrial -40C to +85C temperature range and robust 16-bit ADC for 4-20mA loop or HART-style signal conditioning. The MCCP/SCCP modules generate precise PWM outputs for actuator control, and CLC implements signal edge detection without external logic. The 28-QFN ML package with exposed thermal pad keeps the MCU cool even in sealed IP67 enclosures. XLP sleep modes let the transmitter idle between measurements, drawing <1uA average - critical for loop-powered 4-20mA field instruments.
Recomendado
Low-Power Wireless Sensor Platform
The PIC24F08KM102T-I/ML fits low-power wireless sensor platforms because its XLP nanoWatt sleep currents in the sub-nanoamp range and fast wake-up time make it ideal for duty-cycled wireless protocols. The 16-bit core handles packet framing, encryption, and sensor fusion before sleeping, while CLC offloads preamble detection. Paired with an SPI-connected sub-GHz or BLE transceiver, the PIC24F KM part runs on a coin cell for years. The 28-QFN ML package fits small wearable form factors. Designers migrate to PIC24F08KM202T-I/ML when more I/O pins are needed for multiple sensors.
Recomendado
LED Lighting Controller
The PIC24F08KM102T-I/ML is well suited for LED lighting controllers because its 32MHz 16-bit core and MCCP/SCCP modules generate precise PWM dimming curves while CLC implements hardware fault detection. The 12-bit ADC reads ambient light sensors and constant-current driver feedback for closed-loop brightness control. XLP sleep reduces standby power below regulatory limits for Energy Star and EuP compliance. The 28-QFN ML package's small footprint fits inside LED bulb base PCBs alongside the driver stage. Upgrading to PIC24EP256MC204-I/PT adds more Flash for complex lighting protocols like DALI or DMX.
Recomendado
Motor Control Peripheral (Small BLDC/Fan)
The PIC24F08KM102T-I/ML fits small BLDC and fan motor control peripherals because the MCCP/SCCP modules deliver complementary PWM outputs with dead-band control, and the 32MHz core handles sensorless back-EMF zero-crossing in real time. The 12-bit ADC samples motor current and back-EMF with low latency, while CLC implements hardware overcurrent protection that shuts down the FETs within microseconds - faster than firmware response. The 28-QFN ML package fits inside small motor housings and the exposed pad dissipates up to ~0.5W for indoor fan applications.

Notas de diseño
The 28-QFN (6x6 mm) ML package has an exposed thermal pad that MUST be soldered to the ground plane. Failure to solder the e-pad results in poor thermal dissipation, reduced ADC reference stability, and possible mechanical lift during vibration. Use an array of thermal vias (0.15mm drill, 0.5mm pitch) under the pad to connect top and bottom ground pours for optimal heat spreading and electrical reference integrity.
Place a 100nF decoupling capacitor within 3mm of each VDD pin (pin 18 and pin 28) and a bulk 1uF to 10uF capacitor near the MCU VDD traces. For the analog AVdd rail if used, isolate it with a ferrite bead from digital Vdd and add a dedicated 100nF + 10uF decoupling network. The KM family's XLP sleep currents are extremely low (<1uA), so the decoupling capacitors dominate the steady-state power budget - choose low-leakage X7R ceramics to preserve low-power behavior.
Estimated: The PIC24F08KM102 is in the KM (non-FV) family, so its VDD max is 3.6V - connecting it to a 5V rail will damage the part. Verify on the Microchip datasheet cover page before PCB bring-up. Also, the CONFIG words must be programmed at the very beginning of firmware; otherwise the MCU may boot with an undefined oscillator or watchdog state. Use MPLAB X IDE with the XC16 compiler for proper CONFIG bit support.
Keep the 32.768kHz crystal traces short and symmetric to minimize load capacitor mismatch. For ADC applications, route analog signals (ANx pins on PORTA) away from high-speed digital lines (PORTB, PORTC switching pins), and use a guard ring tied to analog ground around sensitive analog traces. The CLC outputs should be routed to avoid crossing clock signals to prevent glitch injection into the analog measurement.
