PIC24F08KL302T-I/MQ Overview
Key features include run-mode currents under 350 uA/MHz at 1.8V, multiple low-power sleep modes (Doze, Idle, Sleep), and a wide industrial temperature range of -40C to +85C. The 28-QFN package is footprint-compatible across the PIC24F08KL/KA families, which enables PCB reuse between pin-compatible variants and code-compatible derivatives.
Architecturally, the PIC24F08KL302 uses the PIC24 16-bit modified Harvard core with a 16-element 16-bit working register file and a 32 kHz to 32 MHz internal oscillator, eliminating the need for an external crystal in many designs. The MSSP peripheral supports both SPI and I2C master/slave, while the 5 CCP/ECCP channels handle PWM and capture/compare functions. Integrated 10-bit ADC, comparators, and a hardware RTCC reduce BOM cost and PCB area.
Typical applications include consumer white goods, low-cost sensor nodes, battery-powered IoT peripherals, e-metering front ends, and small appliances. The XLP feature set also makes it suitable for always-on wearable accessories and remote-control keyfobs. Because the KL/KA series shares its peripheral set with PIC18, designs that start with PIC18 can migrate upward to PIC24 without rewriting drivers.
When designing with this part, note that the QFN package requires thermal vias under the exposed pad for proper heat dissipation. Decoupling capacitance of at least 100 nF placed within 3 mm of each power pin, plus a 10 uF bulk cap, is recommended for stable XLP sleep behavior.

Typical Applications
PIC24F08KL302T-I/MQ is suitable for 6 applications: Battery-Powered IoT Sensor Nodes, Consumer Appliance Control, Wearable Health Monitoring, Smart Home Lighting Control, Electronic Metering Front End, Remote Control Keyfobs.
Battery-Powered IoT Sensor Nodes
The PIC24F08KL302T-I/MQ is well-suited for battery-powered IoT sensor nodes thanks to its nanoWalt XLP low-power modes with run currents under 350 uA/MHz at 1.8V and a 1.8V-3.6V operating range. The 10-bit ADC samples temperature, humidity, or other analog sensors with minimal CPU intervention, while Sleep + RTCC modes keep quiescent current in the microamp range. The MSSP peripheral runs I2C or SPI sensor buses directly, and 8 KB Flash accommodates BLE/HoneyBee/LoRa command stacks.
Recommended
Consumer Appliance Control
The PIC24F08KL302T-I/MQ targets cost-sensitive consumer appliances such as rice cookers, washing machines, and induction cooktops. The CCP/ECCP peripheral generates precise PWM outputs for motor control, heater regulation, and triac-fired loads, while the 16-bit PIC24 core runs closed-loop control loops without sacrificing MIPS headroom. Industrial -40C to +85C operation covers kitchen environments, and 8 KB Flash supports graphical user interfaces and fault logging.
Recommended
Wearable Health Monitoring
Wearable health devices benefit from the PIC24F08KL302T-I/MQ's combination of nanoWalt XLP, small 28-QFN footprint, and PIC24 16-bit processing throughput. Sleep currents in the microamp range extend battery life for heart-rate, SpO2, and step-counter wearables, while the 32 MHz CPU processes sensor-fusion routines without external DSP. The MSSP I2C/SPI bus interfaces with biometric sensors and low-energy wireless companions, and 1 KB SRAM is sufficient for short BLE command buffers.
Recommended
Smart Home Lighting Control
The PIC24F08KL302T-I/MQ drives smart home lighting nodes including LED dimmers, color controllers, and DMX-compatible fixtures. The CCP/ECCP channels generate high-resolution PWM for dimming and color mixing, while the MSSP peripheral handles I2C or SPI control from external wireless modules such as BLE or Zigbee. Industrial temperature range and 1.8V-3.6V operation let it share a 3.3V regulator with downstream radios. XLP modes enable battery-powered remotes and wall switches that run for years on a coin cell.
Recommended
Electronic Metering Front End
Single-phase electronic meters and submetering front ends rely on the PIC24F08KL302T-I/MQ's 16-bit ADC sampling and compute performance. The CCP/ECCP channels drive metrology calibration signals and zero-cross detection for power-line cycle measurements, and 8 KB Flash holds calibration tables and metrology libraries. Low-power Sleep plus RTCC provides timekeeping for time-of-use billing while quiescent current stays minimal. The industrial temperature range supports outdoor meter enclosures.
Recommended
Remote Control Keyfobs
Remote control keyfobs for automotive, garage doors, and security systems use the PIC24F08KL302T-I/MQ to minimize idle current while remaining responsive to button events. XLP Sleep currents in the single-digit microamp range let coin-cell batteries last multiple years, and the wake-up time from Sleep is fast enough for instant button response. The MSSP peripheral drives sub-GHz transceivers over SPI, and the 16-bit PIC24 core runs rolling-code security algorithms efficiently.

- Pin-to-pin compatible with the broader KL/KA family (vs PIC24EP32GP202-I/MM)
Design Notes
The 28-QFN (MQ) package exposes a thermal pad on the underside that should be soldered to a copper pour on the PCB. Use an array of thermal vias (typically 0.3 mm drill, 0.6 mm pitch, 9-12 vias) connecting the pad to inner ground planes to spread heat. At 32 MHz and 1.8V the device dissipates only a few milliwatts, so thermal concerns are minor unless the part is used in a sealed enclosure above 70 C ambient.
Place a 100 nF decoupling capacitor within 3 mm of each VDD pin (pin 5 and pin 20) and add a single 10 uF bulk capacitor near the device. For XLP Sleep-mode operation, keep the bulk capacitor's leakage below 1 uA to avoid dominating the MCU's quiescent current. If the application uses a switched-mode supply, add a small ferrite bead on VDD to suppress switching noise from coupling into the analog inputs.
Do not skip the exposed-pad soldering step on the QFN package - an unsoldered thermal pad increases thermal resistance and reduces long-term solder-joint reliability. Confirm that your programmer/debugger supports the 28-QFN MQ pinout (pin 1 is at the dot marker on the upper left when reading the top marking). When migrating firmware from PIC24F08KL301, watch the configuration-word changes for the 8 KB Flash region and the additional CCP/ECCP channels.
Route the analog signals (RA0-RA3) away from the PWM outputs (RB5-RB7) and from the high-current traces of any nearby switching regulators. Keep the MSSP I2C/SPI traces short and matched, with a 4.7 kohm pull-up on each I2C line. Place the 32.768 kHz crystal (if used for RTCC) close to the SOSCO/SOSCI pins with a guarded ground pour to minimize coupling from digital signals.
