PIC24F08KL302-I/SS - 32MHz 16-bit XLP MCU | Microchip
MPN: PIC24F08KL302-I/SS ✓ ActivePIC24F08KL302-I/SS Overview
A microcontroller is a programmable semiconductor that integrates a processor core, nonvolatile program memory, volatile data memory, and peripherals such as ADCs, timers, communication modules, and general-purpose I/O into one device. The PIC24F08KL302 belongs to the PIC24F family of 16-bit flash microcontrollers, a product hierarchy within embedded processors and microcontrollers. Its nanoWatt XLP technology is intended for low-power operation, while its 17 I/O ports provide connections to sensors, switches, indicators, and external interface circuits.
The principal device characteristics include 8 KB of Flash, 1 KB of SRAM, 512 bytes of EEPROM, operation up to 32 MHz, and a 10-bit ADC. The integrated Master Synchronous Serial Port supports I2C and SPI, while CCP and ECCP peripherals provide configurable capture, compare, and PWM-related capabilities. These resources allow a compact design to measure an analog input, exchange data with a sensor or peripheral, control outputs, and retain configuration or calibration data without adding several discrete components.
The 28-pin SSOP package provides a practical balance between pin availability and board area. A 3.3 V-class supply is central to the supplied operating information, and the industrial variant is reported for operation from -40°C to +85°C. Designers should treat the ADC, communication, and timer functions as the main architectural blocks: the ADC converts analog voltage into digital values, MSSP handles serial protocols, and the CCP/ECCP blocks support timing and output-control tasks.
Typical uses include low-power sensor nodes, industrial monitoring equipment, serial data bridges, compact consumer controls, cost-sensitive peripheral controllers, and embedded products that periodically wake from a low-power state. The combination of 16-bit processing, Flash program memory, EEPROM, ADC, MSSP, and 17 I/O pins is especially useful when the board must handle both control logic and real-world analog signals while maintaining a small component count.
A key design consideration is to confirm the exact pin assignments, electrical limits, and peripheral multiplexing in the manufacturer datasheet before laying out the PCB. Decoupling should be placed close to the supply pins, and unused I/O pins should be handled according to the device guidance. Because the available verified results do not provide exact prices, lead times, complete pin names, or thermal and package drawings, those fields require confirmation rather than inference.

Typical Applications
PIC24F08KL302-I/SS is suitable for 6 applications: Low-Power Sensor Node, Industrial Condition Monitoring, Serial Sensor and Peripheral Bridge, ADC-Based Analog Control Panel, Cost-Sensitive Consumer Appliance Controller, Embedded Data Acquisition Module.
Low-Power Sensor Node
The PIC24F08KL302-I/SS fits a compact sensor node because it combines nanoWatt XLP low-power technology with a 10-bit ADC and 17 I/O ports. The MCU can sample an analog sensor, evaluate the measurement, and control an indicator or actuator through available I/O. Its 32 MHz maximum clock provides useful processing headroom, while MSSP supports I2C or SPI links to digital sensors, memory, or remote sensor hubs. The 28-pin SSOP also limits board footprint without requiring the 28-QFN package used by the /MQ ordering code. Final power performance depends on the selected XLP mode, wake-up source, and peripheral activity, which must be confirmed from the manufacturer datasheet.
Recommended
Industrial Condition Monitoring
The PIC24F08KL302-I/SS is appropriate for industrial condition-monitoring equipment requiring an industrial-temperature controller with mixed-signal input and serial expansion. Its 10-bit ADC can acquire a conditioned analog voltage, while 17 I/O ports support switches, status indicators, relays, and digital sensors. The MSSP peripheral provides I2C or SPI connectivity to remote sensing modules, and the CCP and ECCP blocks support timing and output-control functions. The 8 KB Flash provides firmware space for acquisition logic and calibration behavior, while 512 bytes of EEPROM can support nonvolatile configuration storage. For production equipment, confirm the industrial temperature qualification and complete electrical limits before release.
Recommended
Serial Sensor and Peripheral Bridge
The PIC24F08KL302-I/SS can act as a compact serial bridge between an I2C or SPI sensor and a higher-level embedded controller. Its MSSP peripheral handles the serial link, and the 16-bit core running up to 32 MHz can translate data, apply filtering, or manage a simple command protocol. Sixteen-bit arithmetic can be useful when scaling sensor readings or performing fixed-point operations, while 8 KB of Flash accommodates protocol handling and application logic. The 28-pin SSOP footprint is convenient for space-conscious secondary controller boards. Because the verified information does not specify maximum bus rates or detailed peripheral operating conditions, those limits must be taken from the current manufacturer datasheet.
Recommended
ADC-Based Analog Control Panel
The PIC24F08KL302-I/SS supports a compact analog control panel that converts sensor voltages into digital measurements and drives user or machine outputs. The integrated 10-bit ADC handles basic measurement tasks, while 17 I/O ports provide connections to buttons, encoders, indicators, and discrete actuators. Its CCP and ECCP peripherals add configurable timing and output functions, and the 1 KB SRAM provides working memory for acquisition and control routines. The processor operates up to 32 MHz, allowing control logic and communication to share one device rather than requiring separate analog and digital components. The number of usable ADC channels and analog operating limits still need verification in the manufacturer documentation.
Recommended
Cost-Sensitive Consumer Appliance Controller
The PIC24F08KL302-I/SS suits cost-sensitive consumer appliances that need local control, serial communication, and occasional analog measurement without a high-performance processor. Its 16-bit architecture and 32 MHz maximum clock can manage user inputs, drive indicators, and coordinate an I2C or SPI peripheral through MSSP. NanoWatt XLP technology is relevant for products that spend substantial time idle, while Flash supports field-updatable application code and EEPROM can retain configuration values. The 28-pin SSOP package is compatible with automated surface-mount assembly. Designers should verify startup behavior, brownout handling, and the precise low-power current figures in the manufacturer datasheet before optimizing standby consumption.
Recommended
Embedded Data Acquisition Module
The PIC24F08KL302-I/SS can serve as the controller in a small data-acquisition module that samples an analog signal, stores operating parameters, and forwards results over a serial link. The 10-bit ADC provides the conversion function, 1 KB of SRAM supports temporary processing, and 512 bytes of EEPROM preserves configuration or calibration data. MSSP enables I2C or SPI communication with external sensors or a host, while CCP and ECCP can support precise timing tasks. Its 32 MHz clock allows the acquisition sequence and communication protocol to operate without a separate processor. The available data does not state ADC channel count or acquisition timing, so those specifications must be confirmed before fixing the sampling architecture.

Design Notes
Treat the 28-SSOP footprint as a constrained mixed-signal layout problem. Place the device where short analog traces can reach the ADC-related pins while keeping switching supplies and high-current outputs away from sensitive input routing. The verified snippets do not provide exact pin numbers, so assign I/O, ground, supply, and analog functions only after checking the current Microchip 28-pin pinout and package drawing; do not infer them from the /MQ QFN variant.
The verified supply range for this ordering code is 3 V to 3.6 V, so the power system should be designed around a 3.3 V-class rail with appropriate tolerance and sequencing. Decoupling capacitance, bulk capacitance, and allowable supply ramp rate must be selected from the manufacturer datasheet rather than inferred from generic MCU practice. Because nanoWatt XLP can reduce average consumption only when unused peripherals and I/O are configured correctly, measure the complete operating mode rather than a single idle state.
Do not substitute PIC24F08KL302-I/MQ for the /SS target. The verified distributor listings identify /SS as 28-SSOP and /MQ as 28-QFN, 5 mm by 5 mm, so the land patterns are not interchangeable despite the shared base device name. Likewise, do not assume that a lower-memory same-family part is interchangeable without checking Flash usage, RAM demand, ADC configuration, MSSP resources, and temperature requirements.
Reserve a clean, low-impedance return path for the MCU and analog measurement circuitry. If the board combines this controller with switching power conversion, keep the supply regulator’s high-current path and its high-di/dt node separated from the ADC input and reference routing. The available verified information does not include package dimensions or exposed-pad details, so confirm the mechanical drawing and recommended land pattern directly from Microchip before fabrication.
Compliance Information
RoHS compliance is reported by the verified JLCPCB listing. The supplied sources do not explicitly establish REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status, so those values remain unknown.
