PIC24F08KM202-I/SP - 32MHz 16-Bit Low-Power MCU | Microchip
MPN: PIC24F08KM202-I/SP ✓ ActivePIC24F08KM202-I/SP Overview
A PIC24F is a 16-bit reduced-instruction-set microcontroller within Microchip’s PIC family of embedded-control semiconductors. The XLP designation identifies devices intended for low-power operation, while the integrated analog peripherals reduce the need for separate components in compact systems. This combination of digital processing, Flash memory, and on-chip analog functions supports cost-conscious industrial, consumer, sensor, and control applications.
The PIC24F08KM202-I/SP integrates a 12-bit ADC, an 8-bit DAC, op amps, and configurable logic functionality. These resources can be used to acquire sensor signals, generate analog control or reference voltages, and implement local analog signal conditioning. The 8 KB Flash memory provides 2.75K words of program storage, while 2 KB of SRAM supports working data, buffers, and stack-intensive routines. A 32 MHz clock provides the processing headroom needed for responsive control loops and peripheral coordination.
The -I/SP ordering designation identifies the industrial-temperature, through-hole packaging option, supplied in a 28-pin SPDIP package. The specified package measures 0.300 inches in body width with a 7.62 mm lead pitch. Its operating range of 1.8 V to 5.5 V accommodates systems powered from low-voltage rails while allowing connection to sensors and actuators operating at lower thresholds. Exact peripheral counts, pin functions, and electrical limits should be confirmed in the manufacturer datasheet before schematic capture.
Typical uses include environmental monitoring, industrial sensor interfaces, compact control panels, low-power instrumentation, and consumer products requiring an analog output. In a sensor node, the ADC can acquire a conditioned input while the DAC provides a reference or actuator command. The integrated op amps can assist with signal conditioning when their electrical characteristics match the application, reducing component count and preserving an efficient board layout.
The main design consideration is power architecture. Because the microcontroller combines several active blocks, the system should enable only the peripherals it needs and place the device into an appropriate sleep mode during idle periods. Decoupling should follow the pin-specific recommendations in the manufacturer datasheet, and analog signal routing should be kept separate from switching nodes and high-current return paths.

Typical Applications
PIC24F08KM202-I/SP is suitable for 6 applications: Industrial Sensor Monitoring, Low-Voltage Control Systems, Compact Data Acquisition Module, Programmable Test and Measurement Equipment, Consumer Appliance Controller, Low-Power IoT Sensor Node.
Industrial Sensor Monitoring
The PIC24F08KM202-I/SP fits compact sensor-monitoring modules because it combines a 12-bit ADC, 2 KB of SRAM, and a 32 MHz PIC24F core in one 28-pin SPDIP package. The microcontroller can acquire conditioned analog inputs while retaining enough memory for calibration, filtering, and local data handling. Its 1.8 V to 5.5 V operating range also supports low-voltage industrial sensing architectures. The industrial-temperature ordering option is useful where the product must operate reliably across a wider commercial temperature range. Designers should confirm the ADC input limits, acquisition timing, and required analog settling behavior in the manufacturer datasheet before finalizing the front end.
Recommended
Low-Voltage Control Systems
The PIC24F08KM202-I/SP is suitable for embedded control boards operating from 1.8 V to 5.5 V. Its 32 MHz processing speed supports responsive digital control, while the integrated 12-bit ADC can monitor process variables and the 8-bit DAC can provide an analog command or reference level. The 28-pin through-hole package simplifies prototype assembly and serviceable industrial control products. Power-management design should disable unused analog blocks and use suitable low-power modes when the controller is waiting for new measurements. Exact peripheral multiplexing and pin constraints must be reviewed because several resources share a limited number of 28 pins.
Recommended
Compact Data Acquisition Module
The PIC24F08KM202-I/SP can serve as the controller for a compact data-acquisition module by combining a 12-bit ADC, 8 KB of Flash, 2 KB of SRAM, and high-speed 16-bit processing. The MCU can sample analog channels, apply scaling and filtering, and retain operating state locally. At 32 MHz, it provides additional timing headroom for communication tasks or configurable logic functions beyond basic sampling. For higher channel counts or resolution, an external converter such as the MCP3424 can complement the MCU, while the PIC’s op amps can assist with conditioning. The analog ground, reference, and decoupling arrangement should follow the manufacturer’s layout recommendations.
Recommended
Programmable Test and Measurement Equipment
The PIC24F08KM202-I/SP is useful in small programmable test fixtures because its 12-bit ADC can acquire sensor or DUT voltage measurements, its 8-bit DAC can generate stimulus, and its 32 MHz core can coordinate test sequences. The 28-pin SPDIP package also supports serviceable fixtures and educational or laboratory control boards. Designers can use the integrated analog functions to create a compact source-and-measure architecture rather than relying on separate stimulus and acquisition ICs. Accuracy still depends on reference quality, calibration, grounding, input protection, and the selected acquisition mode. Validate those details against the device electrical characteristics before assigning measurement accuracy.
Recommended
Consumer Appliance Controller
The PIC24F08KM202-I/SP can serve as the embedded controller in a compact appliance or user-interface product that needs sensing and analog output without a complex analog subsystem. The 1.8 V to 5.5 V range supports low-energy operation, while 8 KB of Flash and 2 KB of SRAM are adequate for focused control firmware, parameter storage, and user-interface state. The 12-bit ADC can monitor switches, temperature elements, or potentiometers, and the DAC can generate a low-resolution control signal. Through-hole construction is particularly convenient for prototypes and manually assembled products. Firmware must account for startup, brownout behavior, and unused-pin configuration specified in the manufacturer documentation.
Recommended
Low-Power IoT Sensor Node
The PIC24F08KM202-I/SP aligns with compact IoT sensor nodes because the PIC24F XLP family targets low-power operation and the device combines measurement resources with a 32 MHz microcontroller. Its 12-bit ADC supports sensor acquisition, 2 KB of SRAM can buffer measurements, and the 8-bit DAC can provide an output where required. The 1.8 V minimum operating voltage helps align the MCU with low-voltage power architectures. A practical design should minimize active peripherals, use suitable sleep modes, and account for sensor and radio energy use beyond the controller itself. The through-hole package is advantageous during IoT prototyping and rework, although production designs may migrate to a surface-mount package after validation.

Design Notes
Plan the power tree around the device’s 1.8 V to 5.5 V operating range, and verify that every connected peripheral shares a compatible voltage domain. Disable unused analog functions and use the appropriate low-power operating modes to reduce consumption. Treat the controller, sensors, and communication circuitry as a complete energy budget rather than optimizing the MCU in isolation.
Follow the manufacturer’s pin-specific bypass recommendations and place the required decoupling capacitors adjacent to the corresponding supply pins. Keep the 28-pin SPDIP footprint unobstructed so the device can be inserted and removed without stressing nearby components. Provide adequate clearance around the package and follow the exact mechanical drawing when creating the through-hole land pattern.
Route analog inputs away from switching signals and high-current return paths, and use a quiet ground strategy for the ADC and op-amp circuitry. If the internal DAC output drives sensitive loads, condition it appropriately and verify its stability, output range, and capacitive-drive limitations in the manufacturer documentation. PCB cleanliness and stable reference routing are important for repeatable measurements.
Do not treat PIC24F08KM202-I/SP and PIC24F08KM202-I/SO as interchangeable because one uses SPDIP and the other uses SOIC. Also avoid assuming that a related package code preserves pin multiplexing, programming, or peripheral access. Confirm the complete ordering code, package drawing, pin table, programming interface, and electrical limits against the manufacturer datasheet before releasing production artwork.
Compliance Information
The -I/SP ordering code identifies an industrial-temperature package, but RoHS, REACH, lead-free, halogen-free, conflict-minerals, and automotive-qualification status require confirmation from current Microchip product declarations.
