PIC24F08KL301-I/SS - 16-bit 32MHz 8KB Flash XLP MCU | Microchip
MPN: PIC24F08KL301-I/SS ✓ Hoạt độngPIC24F08KL301-I/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O onto one die. The PIC24F family belongs to the 16-bit MCU category, which sits between 8-bit MCUs (PIC10/12/16/18) and 32-bit MCUs (PIC32). It is part of the broader embedded processor taxonomy that includes DSPs, application processors, and FPGAs. The 16-bit class targets cost-sensitive applications that need more computational headroom and code density than 8-bit parts but do not justify 32-bit pricing.
Key features include the nanoWatt XLP deep-sleep modes with currents down in the microamp range (specific values vary by mode), an integrated MSSP peripheral supporting both I2C and SPI, a CCP/ECCP module for PWM and capture/compare, 10-bit ADC, multiple timers, and configurable I/O. The device runs from 1.8V to 3.6V across two main operating ranges (2.5V/3.3V typical) with on-chip voltage regulation, making it compatible with both 2-cell battery and 3.3V regulated rails.
Architecturally, the PIC24F08KL301 uses a Harvard RISC core with a modified Harvard bus and a 16-bit wide instruction path, a 17-bit x 15-bit working register array, and a single-cycle hardware multiply. Its peripheral set is intentionally aligned with the PIC18 family to ease migration for designers upgrading from 8-bit to 16-bit performance. AEC-Q100 grade availability supports automotive deployment where 8-bit PICs are insufficient.
Typical applications include low-power battery-powered sensor nodes, consumer appliances, home automation, motor control peripherals, USB/CDC bridges, smart metering, and cost-sensitive IoT endpoints where the eXtreme Low Power modes extend coin-cell battery life. The wide 1.8V-3.6V supply also supports direct operation from 2xAA/2xAAA cells without a boost regulator.
When designing with this part, choose the correct oscillator mode (internal 8 MHz FRC or external crystal) early because the PLL configuration determines achievable system clock. Plan ICD/ICSP header pinout before PCB layout so that the low-pin-count debug (PGECx/PGEDx) pins remain accessible. Also reserve the analog supply rail even when ADC is unused, because the AVSS/AVDD pins must still be bonded.

Ứng dụng tiêu biểu
PIC24F08KL301-I/SS phù hợp cho 6 Áp dụngs: Battery-Powered Sensor Node, Home Appliance Control Board, USB-to-UART Bridge / CDC Device, Low-Cost IoT Endpoint with Sub-GHz Radio, Automotive Body Electronics (AEC-Q100), Educational / Maker Development Board.
Battery-Powered Sensor Node
The PIC24F08KL301-I/SS is purpose-built for low-duty-cycle sensor nodes where nanoWatt XLP Sleep and Deep Sleep modes dominate the energy budget. Drawing microamp-level quiescent current with RTCC and WDT active lets a coin-cell node run for years sampling temperature, humidity, or PIR events. The 16-bit PIC24F core handles 32 MHz bursts to process I2C sensor reads in microseconds, then returns to sleep. With 8 KB Flash and 1 KB RAM, firmware fits sensor drivers, a small RTOS loop, and over-the-air update stubs. The 20-pin SSOP remains hand-solderable for prototype rework while staying small for SMD mass production.

Home Appliance Control Board
In washing machines, dishwashers, and coffee makers, the PIC24F08KL301-I/SS drives triac-controlled AC loads via opto-isolated GPIO and reads keypad/encoder inputs through ADC. The CCP/ECCP module generates precise PWM for universal-motor speed control, while the MSSP serves I2C displays or SPI LED drivers. Operating from a rectified 3.3 V rail with the on-chip voltage regulator simplifies SMPS design and shrinks BOM cost. The 20-pin SSOP balances IO count with PCB space, leaving enough headroom for a small graphical LCD or segment display.

USB-to-UART Bridge / CDC Device
The PIC24F08KL301-I/SS, paired with an external USB transceiver or a software-only USB stack on capable PIC24F variants, implements a CDC bridge that appears as a virtual COM port on a host PC. UART speeds to 1 Mbps are easily handled by the 32 MHz core with hardware buffering in 1 KB RAM. Industrial 3.3 V RS-485 adapters built around this MCU use the MSSP for SPI flash storage of configuration profiles. The small SSOP-20 footprint is ideal for inline cable dongles and panel-mount modules.

Low-Cost IoT Endpoint with Sub-GHz Radio
Combined with an SPI-driven Sub-GHz transceiver such as the Microchip MRF89XA or equivalent, the PIC24F08KL301-I/SS forms a battery-friendly IoT endpoint for smart metering, agricultural sensing, and asset tracking. The MSSP drives the SPI bus at the radio's full data rate, while the 16-bit core executes MAC-layer timing with microsecond precision. Deep-sleep current near 100 nA (per datasheet DC table) lets a 2xAA pack survive multi-year deployments in the field.

Automotive Body Electronics (AEC-Q100)
The PIC24F08KL301 family includes AEC-Q100-qualified variants that handle interior lighting, mirror control, and seat-position memory in body-electronics modules. The 16-bit core runs LIN-stack software in firmware while the ECCP module drives LED dimming via PWM. Operating from an automotive 12 V rail stepped down to 3.3 V, the MCU survives load-dump and cranking transients when paired with proper TVS protection. The -40 C to +125 C extended-temp grade is mandatory for under-hood modules.
Được đề xuất
Educational / Maker Development Board
The PIC24F08KL301-I/SS is a popular 16-bit teaching platform thanks to its 20-pin SSOP breadboard-friendly breakout, MPLAB X IDE support, and XC16 compiler. Students learn 16-bit timer architecture, ADC sequencing, and I2C/SPI peripherals without the cost of a 32-bit part. The ICSP pins (PGECx/PGEDx) enable real programmer/debugger use, reinforcing embedded workflow skills that scale up to PIC32 and dsPIC families.

Ghi chú thiết kế
Estimated: at VDD = 3.3 V, 32 MHz active, the PIC24F08KL301 typically draws 5-8 mA. Switching to nanoWatt XLP Sleep mode (no peripherals) drops current to a few microamps, and Deep Sleep with RTCC can reach single-digit microamps or lower depending on configuration bits. For battery-life calculations, read the datasheet DC table for the exact Sleep/Deep Sleep current at your chosen VDD, and add any peripheral bias currents (WDT, RTCC, BOR). Decoupling: place a 0.1 uF ceramic on VDD/AVDD and a 1 uF bulk near the MCU; add a 10 uF tantalum or polymer if the rail is shared with radio modules.
Reserve the ICSP/ICD footprint (PGECx and PGEDx pins) on every prototype PCB, even if you do not plan to populate a header in production. The 20-pin SSOP variant exposes these on Port B, so a 2x3 100-mil header is easy to add and lets you re-program or debug in-circuit later. Keep the ICSP traces short (<50 mm) and isolated from switching nodes; add a small series resistor on MCLR if the pin is also used as a reset button to avoid programming interference.
AVDD/AVSS pins must always be bonded even when the ADC is unused; leaving them floating can inject noise into the digital VDD rail via the internal voltage regulator. Place the analog ground pour directly under the analog I/O traces and stitch to digital ground at a single point near the AVSS pin. For high-precision ADC readings (10-bit or 1 LSB target), keep analog traces away from PWM outputs and clock lines, and add a small RC filter (10 ohm + 100 nF) on each analog input if the source impedance is above 2.5 kohm.
Configuration bits (FOSC, WDTE, BOR, MCLRE) silently change I/O function and clock source. A common mistake is leaving MCLRE disabled and expecting a reset button to work, or choosing an FOSC mode that needs a crystal when only the internal FRC is populated. Always review the Configuration Words register map in the datasheet and lock the device ID before mass programming. Also enable the on-chip voltage regulator's full-power mode (ENVREG tied properly) when running at 32 MHz; otherwise the MCU will run at FRC speed silently.
