PIC24F08KL402-E/SP 개요
A 16-bit microcontroller (MCU) is an integrated circuit containing a CPU, program memory, RAM, and peripherals on a single die. The PIC24F family uses a modified Harvard architecture with 16-bit wide instructions and data paths, offering a balance between the simplicity of 8-bit PIC MCUs and the performance of 32-bit devices. Within the broader taxonomy: microcontroller -> 16-bit MCU -> PIC24F family -> PIC24F08KLx series -> low-power (XLP) variant. This part targets cost-sensitive applications where 16-bit performance is needed without 32-bit complexity.
Key features include extreme low-power operation with nanoWatt XLP sleep currents, a 32 MHz internal oscillator, 23 digital I/O pins with interrupt-on-change capability, and 12 channels of 10-bit analog-to-digital conversion at 500 ksps. The device operates from 1.8V to 3.6V with on-chip voltage regulation, supports in-circuit serial programming (ICSP) and in-circuit debugging (ICD), and offers multiple communication interfaces including I2C, SPI, and UART.
The PIC24F08KL402-E/SP uses a 16-bit RISC-style core with single-cycle multiply and hardware divide, providing deterministic interrupt latency for real-time control. Its nanoWatt XLP technology enables sleep currents below 1 uA, making it suitable for battery-powered sensor nodes, wearable electronics, and remote monitoring equipment where idle power dominates total energy consumption.
Typical applications include IoT sensor nodes, low-power wireless devices, portable medical instruments, consumer electronics with battery backup, industrial sensor interfaces, and home automation controllers. The wide -40C to +125C operating range also supports industrial and outdoor deployments requiring extended temperature tolerance.
When designing with this part, allocate careful attention to the ICSP programming header placement to avoid interference with debug access. The MSSP peripheral requires careful I2C pull-up resistor sizing and timing-budget analysis for multi-master or long-bus configurations.

일반적인 애플리케이션
PIC24F08KL402-E/SP 적합 용도: 6 애플리케이션s: IoT Wireless Sensor Nodes, Battery-Powered Wearable Health Devices, Industrial Sensor Interface Modules, Home Automation Controllers, Portable Medical Instruments, Automotive Body Electronics.
IoT Wireless Sensor Nodes
The PIC24F08KL402-E/SP fits IoT wireless sensor nodes due to its nanoWatt XLP deep-sleep current below 1 uA at 3.3 V, which lets a 2xAA pack run a sensor-and-radio duty cycle for 3 to 5 years without replacement. The integrated 12-channel 10-bit ADC at 500 ksps handles multiple analog sensors, while hardware MSSP drives sub-GHz transceivers over SPI. The 32 MHz 16 MIPS core is sufficient to run MAC stacks, AES-style encoding, and sensor pre-processing before transmitting, and the 1 KB RAM and 8 KB Flash accommodate a lightweight Zigbee or LoRa-style link layer.

Battery-Powered Wearable Health Devices
For wearable health devices like fitness bands and pulse-ox patches, the PIC24F08KL402-E/SP's XLP sleep modes with sub-1 uA idle current and 1.8 V minimum supply enable coin-cell operation for months. The integrated 12-channel ADC reads PPG, temperature, and motion-sensor analog channels simultaneously, and the I2C/SPI peripherals connect to low-power IMUs and biometric sensors. The 8 KB Flash accommodates on-device filtering, while the small SPDIP footprint suits through-hole discrete prototype builds during development.
추천
Industrial Sensor Interface Modules
The PIC24F08KL402-E/SP is well suited for industrial 4-20 mA loop-powered sensor transmitters because its 1.8 V minimum supply operates from the loop, and the -40C to +125C extended operating range survives factory-floor thermal stress. The 12-channel ADC handles multiple transducer inputs at 10-bit resolution, and the ECCP module generates the loop-current modulation signal. The SPDIP package simplifies hand-soldered field replacement, while ICSP allows in-situ firmware updates without removing the module from service.
추천
Home Automation Controllers
For home-automation hubs controlling relays, dimmers, and sensor inputs, the PIC24F08KL402-E/SP's 23 digital I/O pins with interrupt-on-change directly drive Triac gates, sense AC zero-cross events, and read multiple button inputs simultaneously. The hardware I2C/SPI supports lighting-bus bridges and expansion peripherals, while the UART provides a debug console. The 32 MHz throughput runs real-time scheduling and Z-Wave or Zigbee-style bridge logic without external co-processors, and the SPDIP-28 through-hole design simplifies prototyping on perfboard.
추천
Portable Medical Instruments
Medical portable instruments such as handheld glucose meters and portable spirometers benefit from the PIC24F08KL402-E/SP's low 1.8 V supply and sub-1 uA sleep currents, extending battery life across long patient-use cycles. The 10-bit ADC with 12 channels captures both sensor inputs and battery-monitoring signals, while the UART connects to Bluetooth or USB interface modules for data upload. The 8 KB Flash runs lightweight medical-data processing, and the extended -40C to +125C range supports clinical-environment reliability.
추천
Automotive Body Electronics
In automotive body-electronics modules like seat controllers and interior lighting, the PIC24F08KL402-E/SP's extended -40C to +125C operating range handles under-dash thermal conditions, and its 12-channel ADC reads multiple sensors including thermistors and Hall-effect switches. The ECCP module drives LED-driver FETs and motor-control PWM, while the I2C peripherals interface with body-network companion chips. The 8 KB Flash and 1 KB RAM cover seat-position memory and lighting-sequence logic, and the SPDIP package suits aftermarket accessory designs.

설계 노트
Estimated: at VDD = 3.3 V, 32 MHz active current is approximately 6 mA (typical from PIC24F KL family datasheet). For sleep-mode designs, the nanoWatt XLP Deep Sleep mode reduces idle current below 1 uA but requires careful peripheral-state retention planning. Configure unused pins as digital outputs tied low (not floating) to minimize parasitic current draw, and place a 100 nF decoupling capacitor within 5 mm of the VDD pin.
Do not assume any PIC24F KL variant will run on a 5 V supply - the maximum VDD is 3.6 V absolute. Over-voltage damages the part. Also, when migrating between KL402 and KL401, re-verify the program-memory map and I/O pin assignments, since KL401/402/400 differ in peripheral channel count even when pinout appears identical. Finally, ensure the MCLR pin has a 10 kohm pull-up and a 100 nF to VSS for clean reset behavior; floating MCLR is a common source of unreliable startups.
For the 28-SPDIP through-hole footprint, place a 0.1 uF decoupling capacitor on each VDD-VSS pair within 5 mm of the package, and add a bulk 10 uF tantalum or ceramic capacitor near the IC. Keep the MCLR trace short to minimize reset-noise pickup, and route the ICSP PGC/PGD traces with ground-guard separation to avoid debug-session interference during EMI events. Place the crystal or oscillator components within 10 mm of the OSC1/OSC2 pins to minimize clock distortion.
