PIC24F08KL302-I/SO Présentation
A microcontroller unit (MCU) is a self-contained computer on a single die that integrates a CPU core, program memory, data memory, and configurable peripherals. The PIC24F family sits within the 16-bit MCU segment of the broader embedded processing hierarchy: MCU -> embedded processor -> semiconductor. The PIC24F08KL302 targets applications that need more arithmetic headroom than an 8-bit PIC18 while retaining low pin count and low power.
Key features include 8 KB Flash program memory (2.75K x 24-bit words), 1 KB SRAM, 256 B data EEPROM, a 16-bit architecture with hardware multiply/divide, and nanoWatt XLP sleep currents suitable for battery-powered products. The device integrates a 10-bit ADC, multiple 16-bit timers, UART, I2C, and SPI serial interfaces, and a real-time clock/calendar with alarm.
The PIC24F08KL302 uses Microchip's flash-based CMOS process, allowing in-circuit serial programming and reprogramming. Its instruction set is optimized for C compilation, and the device is supported by MPLAB X IDE, MPLAB XC16 compiler, and the MPLAB ICD/REAL ICE debugger ecosystem, which shortens development time for cost-sensitive designs.
Typical applications include portable medical monitors, battery-powered sensor nodes, consumer appliance control panels, smart meters, and industrial data loggers. The 28-pin SOIC package is easy to route on two-layer boards and is compatible with standard SOIC-28 land patterns.
When designing with this MCU, decouple VDD pins with 0.1 uF ceramic capacitors placed close to the package, and use the internal oscillator or an external crystal depending on timing accuracy requirements. The XLP sleep modes allow multi-year battery life when the CPU is duty-cycled.

Applications typiques
PIC24F08KL302-I/SO convient pour 6 applications: Portable Medical Monitors, Battery-Powered Sensor Nodes, Consumer Appliance Control Panels, Smart Meters and Utility Monitoring, Industrial Data Loggers, Handheld Instruments and Test Tools.
Portable Medical Monitors
The PIC24F08KL302-I/SO fits portable medical monitors because its nanoWatt XLP sleep modes and 1.8 V to 3.6 V supply allow long battery life while the 16-bit core at 32 MHz handles sensor sampling and display updates. Its 10-bit ADC digitizes physiological signals such as temperature or pressure, and the integrated RTC/calendar timestamps readings for trend logging. Placed as the main controller, it interfaces to an analog front end over SPI or I2C and to a small LCD over parallel or serial lines. The trade-off is limited 8 KB Flash, so complex algorithms must be kept compact or offloaded; for simple monitoring firmware this is not a constraint.
Recommandé
Battery-Powered Sensor Nodes
The PIC24F08KL302-I/SO is well suited to battery-powered sensor nodes because XLP technology keeps sleep current low and the 1.8 V to 3.6 V range allows direct operation from a lithium coin cell or a 3.3 V rail. The 10-bit ADC samples analog sensors, while MSSP (I2C/SPI) and UART connect to digital sensors and radio modules. In a typical duty-cycled topology the MCU wakes on a timer or external interrupt, reads the sensor, transmits a packet, and returns to sleep. The 8 KB Flash limits protocol stack size, so lightweight custom protocols are preferred over full TCP/IP stacks; this keeps the node simple and power-efficient.
Recommandé
Consumer Appliance Control Panels
The PIC24F08KL302-I/SO suits consumer appliance control panels because it combines a 16-bit core, 8 KB Flash, and integrated CCP/ECCP modules for PWM control of motors, heaters, or backlights at low cost. The 28-pin SOIC package is easy to route on single-sided or two-layer boards, and the 1.8 V to 3.6 V supply matches common 3.3 V logic. In this role the MCU scans buttons, drives a display, and runs a control loop, using the 10-bit ADC for temperature or position feedback. The trade-off is modest memory, so feature-rich user interfaces may require a larger family member; for basic panels the KL302 is sufficient.
Recommandé
Smart Meters and Utility Monitoring
The PIC24F08KL302-I/SO fits smart meters and utility monitoring because its 16-bit core provides the arithmetic headroom needed for energy accumulation and scaling, while the integrated RTC/calendar supports time-stamped billing intervals. The 10-bit ADC samples current and voltage channels through external conditioning, and UART or SPI links to metering AFEs or communication modules. The 1.8 V to 3.6 V supply and XLP modes allow the meter to remain powered from a backup cell during outages. The 8 KB Flash constrains the application, so metering algorithms must be efficient; for single-phase or sub-metering designs this is typically adequate.
Recommandé
Industrial Data Loggers
The PIC24F08KL302-I/SO is suitable for industrial data loggers because the 256 B EEPROM stores calibration constants and configuration without external memory, while the 10-bit ADC and serial interfaces acquire and forward measurements. The 16-bit core at 32 MHz handles timestamping and buffering, and the 28-pin SOIC package tolerates standard industrial assembly. In a typical logger the MCU samples sensors on a timer, stores records in RAM, and streams them over UART or I2C to a host or storage device. The 1 KB SRAM limits buffer depth, so records must be flushed frequently; for low-to-moderate sample rates this is not a limitation.
Recommandé
Handheld Instruments and Test Tools
The PIC24F08KL302-I/SO fits handheld instruments and test tools because its low-power 16-bit core and 1.8 V to 3.6 V supply extend battery runtime, while the 10-bit ADC and CCP/ECCP modules support measurement and signal generation tasks. The 28-pin SOIC package keeps the board small, and MSSP (I2C/SPI) connects to displays, EEPROM, or external converters. In this role the MCU runs the measurement state machine, formats results, and manages the user interface. The 8 KB Flash and 1 KB SRAM require compact firmware, so feature-heavy instruments may need a larger device; for basic handheld tools the KL302 is a cost-effective fit.

Principaux différenciateurs
- Extended-temperature option in the same footprint (vs PIC24F08KL302-E/SO)
- Tape-and-reel packaging for automated assembly (vs PIC24F08KL302T-I/SO)
- Higher peripheral integration than the KL201 (vs PIC24F08KL201-I/SO)
Notes de conception
Decouple every VDD pin (pins 20 and 28 on the 28-pin SOIC) with a 0.1 uF ceramic capacitor placed as close to the package as possible, plus a bulk 1 uF to 10 uF capacitor on the board rail. The PIC24F08KL302-I/SO operates from 1.8 V to 3.6 V, so verify that the chosen rail stays within this window under all load conditions. Estimated: at 32 MHz and 3.3 V the core current is in the low-mA range, so a 10 uF bulk capacitor provides ample transient headroom for typical control applications.
Keep the MCLR pin (pin 1) pulled up to VDD through a 10 kOhm resistor and route it away from noisy switching nodes to avoid spurious resets. Place the crystal or resonator, if used, within a few millimeters of the oscillator pins and guard it with a local ground pour. For the 28-pin SOIC land pattern, use standard 1.27 mm pitch footprints and keep analog input traces short and separated from digital lines to preserve 10-bit ADC accuracy.
Do not exceed the 3.6 V maximum VDD or apply voltages above VDD to any I/O pin, as this can damage the device or trigger latch-up. When migrating firmware from a larger PIC24F device, re-check peripheral register addresses and pin mapping because the KL302 has a reduced peripheral set. Also confirm the programming interface (ICSP) connections are accessible on the final board, since the 8 KB Flash is programmed in-circuit via MCLR, PGD, and PGC.
