MPN： PIC24F08KM102-I/SP ✓ 啟用中PIC24F08KM102-I/SP 概覽
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. The PIC24F family belongs to the broader hierarchy of 16-bit embedded controllers, embedded processors, and programmable semiconductor devices. These devices are used where a compact controller must acquire analog signals, evaluate operating conditions, and control system outputs while consuming little power. The PIC24F KM family specifically targets low-power applications that benefit from integrated analog functions and small pin-count packages.
The PIC24F08KM102-I/SP provides 2.75K x 24 words of Flash organization, 1 KB of SRAM, and 512 bytes of EEPROM according to the product listing. Its 12-bit ADC supports digital measurement of analog inputs, while the integrated comparators, DAC, and operational amplifiers reduce the need for separate analog components. The operating-voltage range of 1.8 V to 5.5 V permits use in both lower-voltage and conventional 5 V embedded systems. The PIC XLP branding identifies the family’s low-power design focus.
The 28-pin SPDIP construction makes this device suitable for prototypes, educational platforms, industrial controllers, and through-hole assemblies where a socketed or easily inspected package is useful. The I designation denotes the industrial-temperature grade, while SP identifies the package form. Unlike a surface-mount implementation, the through-hole DIP format is straightforward to solder manually, prototype, inspect, and replace. Its 16-bit architecture and 32-bit PIC24F-related product family are suited to control logic requiring more computational capability than a basic 8-bit controller.
Typical applications include low-voltage sensor interfaces, compact industrial monitoring equipment, temperature or process-control loops, comparator-based threshold detection, programmable signal conditioning, and embedded control systems with analog outputs. The integrated ADC, comparators, DAC, and op amps allow a compact design to acquire a signal, compare it against a threshold, and generate an analog output without requiring several discrete components. The 1.8 V to 5.5 V range also suits mixed embedded systems that operate from regulated low-voltage rails.
Designers should select decoupling capacitors according to the manufacturer’s recommended application circuit, keep analog and digital routing organized, and verify the DIP pin assignment against the device pin-description table before assigning PCB nets. The available package and peripheral functions do not imply that every ADC, comparator, DAC, or op-amp feature can be used simultaneously; resource allocation and multiplexing must be checked in the manufacturer datasheet. Firmware should also account for the relationship between operating voltage, selected peripheral functions, and clock configuration.
This product page combines the verified manufacturer feature summary, exact package and memory characteristics, relevant comparison data, and practical selection guidance. It is designed to help engineers identify whether the PIC24F08KM102-I/SP provides the required analog resources, memory, voltage range, and through-hole package before beginning PCB or firmware development.

典型應用
PIC24F08KM102-I/SP 適用於 6 應用s: Industrial Sensor Interface, Low-Voltage Process Control, Battery-Powered Monitoring Device, Comparator-Based Threshold System, Programmable Analog Signal Conditioning, Embedded Control and Digital I/O Expansion.
Industrial Sensor Interface
The PIC24F08KM102-I/SP fits low-voltage sensor interfaces because it combines a 12-bit ADC, 1 KB of RAM, and 8 KB of Flash in a compact 28-pin DIP device. Its 1.8 V to 5.5 V operating range supports both low-energy sensor nodes and conventional 5 V controller boards. The on-chip comparators can perform threshold detection around a measured signal, while the op amps can assist with conditioning before digital processing. Because the package is through-hole, the controller is particularly practical for prototypes, industrial test fixtures, and serviceable equipment. The final input network, reference strategy, and protection level must be selected from the device electrical characteristics.

Low-Voltage Process Control
The PIC24F08KM102-I/SP is suited to compact process-control loops where a controller must measure an analog process variable and adjust an actuator signal. Its 12-bit ADC supports digital conversion of the sensed value, while the integrated DAC and op amps can support an analog control output. The 8 KB Flash and 1 KB RAM provide space for a modest control algorithm and operating parameters, and the 1.8 V to 5.5 V range supports low-voltage embedded designs. A 28-pin DIP package also simplifies prototype rework and bench validation. Designers should verify DAC and op-amp operating limits at the selected supply voltage before closing the control loop.
推薦
Battery-Powered Monitoring Device
The PIC24F08KM102-I/SP can serve as the central controller in a battery-powered monitoring device because it belongs to the low-power PIC24F KM family and operates from 1.8 V to 5.5 V. Its 12-bit ADC can sample a sensor, comparators can monitor a threshold without continuously transferring data, and 1 KB of RAM supports short-term measurement processing. The controller can use nonvolatile configuration storage in its 512-byte EEPROM and connect to a host through the available digital peripherals. Power consumption still depends on the selected clock, peripheral configuration, and duty cycle, so battery sizing must follow the manufacturer’s low-power operating guidance.
推薦
Comparator-Based Threshold System
The PIC24F08KM102-I/SP is useful in threshold systems where a monitored signal must be compared with a reference and converted into a digital action. Integrated comparators and CLC capability provide dedicated comparison resources alongside the 16-bit CPU, while the 12-bit ADC can provide a more detailed measurement when required. Operation from 1.8 V to 5.5 V permits use in embedded systems with limited supply headroom. The 28-pin through-hole package makes the part convenient for prototyping threshold logic before a production redesign. Reference stability, comparator input limits, and output routing must be checked against the manufacturer electrical specifications.
推薦
Programmable Analog Signal Conditioning
The PIC24F08KM102-I/SP can implement compact programmable signal conditioning when a system needs to amplify, compare, digitize, and potentially regenerate an analog signal. Its integrated op amps reduce the component count around sensor inputs, the 12-bit ADC converts conditioned measurements into digital values, and the DAC can generate a controlled output where its operating conditions permit. The 16-bit processor can execute filtering and control logic from the 8 KB Flash budget. Analog layout remains critical: separate sensitive input paths from digital switching nodes, use the recommended grounding topology, and verify gain, bandwidth, and output-drive limits for the selected supply voltage.
推薦
Embedded Control and Digital I/O Expansion
The PIC24F08KM102-I/SP works well as a dedicated embedded controller for compact products that need local decisions, analog monitoring, and several digital outputs. Its 16-bit core, 8 KB Flash, 1 KB RAM, and 512-byte EEPROM are adequate for control sequences, status handling, and persistent configuration. The 28-pin DIP package eases prototyping and socket-based maintenance, while the integrated 12-bit ADC allows the controller to supervise an analog subsystem. When the DIP pins do not provide enough general-purpose I/O, an I/O expander can be driven over the available serial interface. Validate the serial peripheral, address selection, and logic levels against the intended expansion device.

主要差異化特點
- Combines several analog functions with a 16-bit controller (對比PIC24FV08KM102-I/SP)

設計說明
Place the device inputs, ground connections, and supply-decoupling components according to the manufacturer’s recommended DIP application layout. Keep analog sensor traces away from digital switching nodes and route them over a continuous ground plane where practical. Because the package has a 0.300-inch, 7.62 mm row spacing, use a standard 28-pin DIP footprint and verify the board orientation against the top-side pin-1 marking before fabrication.
Design the supply path for the complete 1.8 V to 5.5 V operating range and account for the voltage requirements of the selected ADC, DAC, op amps, comparators, and clock configuration. Place the required input capacitor close to the supply pins and provide an appropriate return path for analog currents. A regulator chosen only for nominal 5 V output may not support every operating mode; verify the device’s electrical characteristics at the actual supply and temperature.
Use the manufacturer pin-description table to assign the 28 DIP pins, including power, ground, programming, oscillator, ADC, comparator, DAC, and general-purpose I/O functions. Do not infer analog assignments from the SOIC version because package suffixes select different physical pinouts even when the underlying device family is similar. Confirm programming access and reserved-pin requirements before finalizing the PCB netlist.
Avoid assuming that all integrated analog peripherals can operate independently and simultaneously. Multiplexing, channel availability, reference selection, and output-drive behavior can restrict valid combinations. In firmware, explicitly configure unused pins, analog inputs, comparators, the ADC, and the DAC, and include a defined state for reset and brownout conditions. Validate the final configuration against the device’s electrical and pin-description documentation.
