PIC24F08KL301-E/SO - 16-bit 32MHz 8KB Flash MCU | Microchip
MPN: PIC24F08KL301-E/SO ✓ Hoạt độngPIC24F08KL301-E/SO Tóm tắt
A 16-bit microcontroller (MCU) is a programmable processor that uses a 16-bit data path and instruction word to deliver higher code density, faster arithmetic, and richer peripherals than an 8-bit MCU while remaining lower cost and easier to migrate from than a 32-bit Cortex-M device. The PIC24F family sits in the middle of Microchip's 8/16/32-bit lineup, between the PIC16/PIC18 families and the dsPIC/PIC32 families. Within the 16-bit tier, the PIC24F 'KL' sub-family is the cost-optimized branch targeting high-volume consumer and IoT applications, while the 'KA' branch emphasizes smaller pin-count packages and the 'EP'/'dsPIC' branches add DSP and motor-control features.
Key features of the PIC24F08KL301-E/SO include a 16-channel 10-bit ADC with internal bandgap reference, two analog comparators, a Capture/Compare/PWM (CCP) and Enhanced CCP (ECCP) module for timer and PWM tasks, a Master SSP (MSSP) supporting both I²C and SPI, and the nanoWatt XLP sleep/idle modes that drop active current into the microamp range. It offers up to 18 I/O pins, an 8 MHz internal RC oscillator (with PLL to 32 MHz), and a CTMU for capacitive-touch sensing or simple metering.
Typical applications span home automation sensors, low-cost HMI panels, sensor nodes, battery-powered consumer products, and low-end motor or lighting controllers. The wide operating voltage (1.8–3.6 V) directly supports single-cell lithium or two-cell AA chemistries.
When designing, reserve one I/O for the in-circuit debug header (PGDx/PGECx) to keep MPLAB Xpress / ICD-3 programming possible, and add a 100 nF decoupling cap adjacent to every VDD pin.

Ứng dụng tiêu biểu
PIC24F08KL301-E/SO phù hợp cho 7 Áp dụngs: Battery-Powered IoT Sensor Nodes, Home Automation Wall Switches & Dimmers, Consumer Appliance User Interface Panels, Low-End DC Motor / Fan Speed Control, Portable Medical Accessories, Industrial Sensor Transmitters, LED Lighting Controllers.
Battery-Powered IoT Sensor Nodes
The PIC24F08KL301-E/SO's nanoWatt XLP sleep modes (sub-µA typical idle current) and 1.8–3.6 V operating range make it ideal for battery-powered IoT sensor nodes that wake periodically to read a temperature, humidity, or motion sensor and transmit over a low-power radio. Its 8 KB flash is sufficient for a small RTOS or state-machine plus a wireless protocol driver, and the MSSP handles I²C sensors directly. The 10-bit ADC and internal 8 MHz oscillator eliminate external components, shrinking BOM cost.

Home Automation Wall Switches & Dimmers
Cost-sensitive home-automation wall switches need low BOM cost, capacitive-touch capability, and triac/PWM drive for dimming. The PIC24F08KL301-E/SO integrates CTMU for capacitive touch buttons, an ECCP module for zero-cross triac control, and the MSSP for I²C connection to a Wi-Fi/BLE co-processor. The 32 MHz CPU handles dimming curves without an external crystal, and the 1.8–3.6 V range allows direct connection to rectified AC step-down supplies.

Consumer Appliance User Interface Panels
Washing machines, microwave ovens, and coffee makers need a 16-bit MCU to drive an LED or character LCD and read a small keypad. The PIC24F08KL301-E/SO provides 18 I/O for segment/key matrix scanning, an ECCP for buzzer tones, and the UART for communication with a main control MCU. The 8 KB flash stores menu strings and small state machines, while the 256-byte EEPROM retains user preferences across power cycles.

Low-End DC Motor / Fan Speed Control
Small DC fans, pumps, and BLDC tools require a 16-bit MCU with PWM, ADC for current sensing, and timers for back-EMF or tachometer feedback. The PIC24F08KL301-E/SO provides ECCP PWM at 32 MHz resolution, a 10-bit ADC for current/tach feedback, and an internal oscillator that eliminates an external crystal in cost-sensitive products. The 8 KB flash is enough for PI speed-loop firmware with safety limits.

Portable Medical Accessories
Portable medical accessories such as pill reminders, peak-flow meters, and pulse-oximetry front-ends benefit from the PIC24F08KL301-E/SO's low power consumption, small SOIC-20 footprint, and 16-bit arithmetic for sensor compensation math. The MSSP connects to I²C biosensors, the ADC reads analog front-ends, and the EEPROM stores calibration constants. The Extended -40C to +125C temperature grade supports storage and transport across varied climates.

Industrial Sensor Transmitters
Loop-powered 4–20 mA industrial transmitters and small industrial sensors need a robust MCU with extended temperature, good ADC, and low sleep current. The PIC24F08KL301-E/SO's -40C to +125C rating, 10-bit ADC with internal reference, and nanoWatt XLP sleep mode allow it to sit on a 4–20 mA loop or two-wire industrial bus without draining the loop. The MSSP handles HART or Modbus co-processor connections.
Được đề xuất
LED Lighting Controllers
Architectural and decorative LED drivers need PWM dimming, current sensing, and DMX/0-10 V control interfaces. The PIC24F08KL301-E/SO's ECCP module delivers smooth PWM at up to 32 MHz resolution for high-frequency dimming free of audible flicker, the ADC monitors LED current, and the UART handles DMX512 or 0-10 V dimming interfaces. The 1.8–3.6 V operation suits buck-driver designs with low-side current sense.

Ghi chú thiết kế
Place a 100 nF X7R decoupling capacitor adjacent to every VDD pin (pin 10) and a single 10 µF bulk capacitor within 25 mm of the MCU. The PIC24F08KL301-E/SO's nanoWatt XLP sleep current is highly sensitive to I/O leakage and to residual current in the core; unused I/O pins should be configured as outputs driving low (not left as inputs) to avoid floating CMOS input currents in the µA range. Estimated: at VDD=3.3 V and 8 MHz active, expect 6–10 mA active, dropping to under 1 µA in sleep with RTCC disabled.
Route the PGD (pin 18) and PGC (pin 17) traces as short, parallel pairs to the ICSP header, keeping them away from switching power traces to avoid programming/debug glitches. The MCLR pin (20) requires a 10 kΩ pull-up to VDD and a 100 nF cap to ground for proper reset; omitting the cap can cause intermittent reset under ESD or brown-out. A 4.7 kΩ series resistor on MCLR can add ESD protection without affecting in-circuit debug.
The PIC24F08KL301-E/SO's I/O are NOT 5 V tolerant when VDD is below 5 V; connecting a 5 V signal to any pin will forward-bias the I/O clamp diodes and potentially latch-up the part. Use a level translator (e.g., TXB0108 or discrete divider) when interfacing to 5 V logic. Additionally, do not enable the on-chip PLL unless the system clock source can sustain it; firmware must configure the OSCCON/CLKDIV registers correctly or the CPU will lock up with no instruction execution.
When using the MSSP in I²C mode at 400 kHz or 1 MHz, place 2.2–4.7 kΩ pull-ups on SDA/SCL — the internal weak pull-ups are too weak for reliable high-speed I²C. For SPI at 16 MHz or above, route CLK/MOSI/MISO as length-matched parallel traces and keep CS short; ground the unused pins of the SPI port to avoid floating emissions. The 10-bit ADC sample-and-hold requires the source impedance to be below 10 kΩ for full accuracy — add an op-amp buffer if the sensor output impedance is higher.
