PIC24F08KL401-E/SS 概要
A 16-bit microcontroller (MCU) is a single-chip computer that combines a 16-bit CPU core, program memory (Flash), data memory (SRAM), non-volatile EEPROM, and a rich set of on-chip peripherals. Within the broader semiconductor taxonomy, the PIC24F KL family sits between 8-bit PIC MCUs and 32-bit PIC32 devices, offering higher code density and faster arithmetic than 8-bit parts while retaining the ease-of-migration and PIC18-compatible peripherals (MSSP, CCP/ECCP) that simplify the transition from legacy designs.
Key features of the PIC24F08KL401 include 12 channels of 10-bit ADC, three 16-bit timers, an MSSP supporting both I2C and SPI, an Enhanced CCP module, a 5-bit DAC reference, two analog comparators, and the nanoWatt XLP ultra-low-power sleep modes that allow deep-sleep currents below 1 A. The 1.8 V to 3.6 V supply range and integrated CTMU make the device suitable for capacitive touch and battery-powered applications.
Architecturally, the part uses a modified Harvard bus with a 16-bit data path and 24-bit instruction word, achieving 16 MIPS at 32 MHz. Peripheral pin select is limited compared with larger PIC24F devices, but the PIC18-compatible peripheral set keeps the footprint familiar for engineers migrating from PIC16F/PIC18F designs.
Typical applications include consumer remote controls, low-cost sensor nodes, battery-powered IoT endpoints, LED lighting controllers, capacitive touch user interfaces, home appliances, and white goods. The KL family is purpose-built for cost-sensitive designs that need 16-bit performance without the bill of materials cost of larger PIC24F or PIC32 devices.
When designing with the PIC24F08KL401, plan oscillator start-up timing and verify minimum VDD rise rates for reliable Flash programming; bulk-decouple VDD with a 100 nF ceramic plus a 4.7 uF bulk cap placed within 3 mm of the supply pin. Use MPLAB X IDE with the XC16 compiler for software development, and refer to the device family data sheet for parametric curves and migration notes.

主な用途
PIC24F08KL401-E/SS の用途: 7 件s: Battery-Powered IoT Sensor Node, Consumer Remote Control with Capacitive Touch, White Goods and Home Appliance Controller, LED Lighting Controller, Capacitive Touch User Interface, Industrial Sensor Module, Consumer Medical Monitoring Device.
Battery-Powered IoT Sensor Node
The PIC24F08KL401-E/SS is well matched to battery-powered IoT sensor nodes thanks to its nanoWatt XLP deep-sleep current below 1 A, 1.8 V to 3.6 V single-cell operation, integrated 12-channel 10-bit ADC and CTMU peripheral. In a typical wake-measure-transmit cycle the MCU spends most of its life in deep sleep, draws <1 A, then wakes via the RTCC to read a sensor over I2C and broadcast over a sub-GHz radio. Compared with PIC16F alternatives it offers 16-bit arithmetic for better filtering math and larger Flash (8 KB) for over-the-air stacks. The SSOP-20 footprint also supports miniaturized boards down to roughly 15 x 20 mm.
おすすめ
Consumer Remote Control with Capacitive Touch
The PIC24F08KL401-E/SS integrates CTMU hardware that, paired with Microchip's mTouch library, implements capacitive touch buttons or sliders with response times under 20 ms. The 16 MIPS throughput handles IR protocol generation, debouncing and LED driver PWM from a single core, while the 8 KB Flash comfortably stores RC5/RC6/Samsung NEC tables. The extended -40C to +125C range suits outdoor remotes and in-car garage controllers. Placing the MCU on the same PCB as a touch pad uses just four I/O, leaving the MSSP and ECCP free for IR-LED drive and external EEPROM storage.
おすすめ
White Goods and Home Appliance Controller
White goods such as washing machines, dishwashers and microwave ovens use the PIC24F08KL401-E/SS for front-panel control, sensor acquisition and motor drive PWM. The 16-bit core runs a small RTOS or state machine in 8 KB Flash, while the ECCP generates complementary PWM signals for motor control and the 12-channel ADC reads temperature, water level and motor current sensors. The -E extended temperature grade supports the high-ambient compartments of appliances, and the SSOP-20 footprint sits comfortably on a two-layer PCB. Adding a watch-dog timer and brown-out reset, the MCU handles years of mains-ripple-coupled noise.
おすすめ
LED Lighting Controller
The PIC24F08KL401-E/SS drives multi-channel LED lighting fixtures via its ECCP module and up to three 16-bit timers, supporting PWM dimming frequencies above 1 kHz to avoid visible flicker. The 10-bit ADC reads ambient light sensors and color-mixing feedback, while I2C or SPI peripherals connect to LED driver ICs like the TLC5947 or WS2801. The nanoWatt XLP deep-sleep mode drops standby power below 50 mW for energy-star compliant fixtures. Designers typically expose PWM on RC1/RC2/RC3 and use the MSSP for driver communication.
おすすめ
Capacitive Touch User Interface
Human-machine interfaces such as cooktops, smart switches and access panels use the PIC24F08KL401-E/SS CTMU peripheral to scan 12 capacitive touch channels through the on-chip 10-bit ADC. The CTMU produces charge-time measurements with sub-pF resolution, enabling robust operation through 5 mm glass overlays. The 16 MIPS core runs the mTouch decoding library plus a UI state machine, and the MSSP drives a small OLED or segment LCD. The wide -40C to +125C temperature range keeps calibration stable in outdoor kiosks and kitchen environments.
おすすめ
Industrial Sensor Module
Industrial sensor modules take advantage of the PIC24F08KL401-E/SS -40C to +125C extended temperature range, integrated 12-channel 10-bit ADC and ECCP for 4-20 mA loop or PWM signalling. The 1.8 V to 3.6 V supply range simplifies battery-backed and energy-harvesting designs, while the MSSP I2C/SPI ports connect to digital sensors, FRAM or RTC chips. The 8 KB Flash comfortably hosts Modbus RTU or simple proprietary protocols. An on-chip comparator and 5-bit DAC reference support threshold-based sensor alarms without external components.
おすすめ
Consumer Medical Monitoring Device
Low-cost consumer health devices such as pedometers, pulse oximeter front-ends and personal thermometers use the PIC24F08KL401-E/SS as the main controller. The CTMU drives capacitive sensor inputs, the 10-bit ADC digitizes analog front-end signals, and the MSSP communicates with BLE or OLED modules. The nanoWatt XLP sleep mode extends coin-cell battery life past one year for periodic-measurement devices. The SSOP-20 footprint reflows easily on standard lead-free profiles and is compatible with low-cost two-layer consumer PCBs.

設計ノート
Decouple VDD with a 100 nF X7R ceramic placed within 3 mm of the supply pin, plus a bulk 4.7 uF tantalum or ceramic on the same net. For battery applications keep the brown-out reset voltage above the minimum Flash programming VDD of 1.8 V; using a 2.2 V BOR setting prevents code corruption during weak-battery events. Place a 10 kohm pull-up on MCLR to VDD and add a 0.1 uF cap to ground for noise immunity per Microchip's recommended reset circuit.
Pin 1 on the SSOP-20 is VDD and pin 20 is VSS, but the device also ties ground on pin 8; both must be connected for return-path integrity. Programming pins PGED (17) and PGEC (18) cannot be repurposed as outputs in any application firmware; Microchip's in-circuit debug reserves them even after code is released. Ensure your firmware does not disable the MSSP module during a low-power sleep without first releasing the I2C bus, or downstream peripherals will see a stuck SDA line.
Route the 32 MHz oscillator traces between OSCI (pin 9) and OSCO (pin 10) on the top layer and surround them with a ground pour. Keep high-speed switching signals such as ECCP PWM more than 5 mm from the ADC analog inputs (AN0-AN11) to avoid coupling noise into measurements. Place the CTMU current source decoupling capacitor as close as possible to the VDD/VSS pair to keep charge-time measurements accurate in capacitive touch applications.
Estimated: at FCY = 32 MHz, VDD = 3.3 V and CPU active at 100% duty, the device draws approximately 8 mA which corresponds to about 26 mW. The SSOP-20 has a typical theta_JA of 95 C/W on a 2-layer JEDEC EIA/JESD51 test board, yielding a 2.5 C temperature rise - well within the -40C to +125C operating range. No external heatsink is required under any documented operating condition.
