PIC24F08KM101-I/SS - 16-Bit 32MHz MCU | Microchip Technology
料号： PIC24F08KM101-I/SS ✓ 量产中PIC24F08KM101-I/SS 概述
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. The PIC24F family belongs to the 16-bit microcontroller hierarchy and is designed for low-cost control, sensing, communications, and mixed-signal applications. Its XLP designation identifies Microchip's low-power platform, aimed at systems where energy efficiency and compactness are important design priorities.
The PIC24F08KM101-I/SS combines 32 MHz processing performance with 8 KB of Flash and 1 KB of SRAM. Its 12-bit ADC supports analog measurements, while the integrated comparator, DAC, and op amps reduce the need for external signal-conditioning components. The device is available in a surface-mount 20-SSOP package measuring approximately 5.30 mm in width, making it suitable for compact control boards and moderate-density production assemblies.
Microchip's PIC24F KM family supports operation across low-voltage supply ranges, with the exact device identified as operating from 1.8 V to 3.6 V. The integrated peripherals can support analog monitoring, threshold detection, waveform generation, and low-level signal conditioning. These capabilities are useful when a design must preserve a small footprint while avoiding separate ADC, comparator, and analog-output components.
Typical applications include industrial sensor controllers, compact consumer appliances, battery-powered instruments, embedded measurement modules, and low-speed communication products. The SSOP package is particularly appropriate for designs that use through-hole-style board assembly rather than the very fine pitch required by leadless packages.
When laying out the board, place decoupling capacitors close to the supply pins and route sensitive analog inputs away from switching nodes and high-current return paths. Confirm the exact pin assignments, voltage tolerances, peripheral multiplexing, and programming configuration in the manufacturer datasheet before releasing the PCB.
This product page combines manufacturer specifications, application-focused engineering guidance, package information, and clearly qualified replacement analysis. It is designed to help engineers evaluate the PIC24F08KM101-I/SS for embedded control designs while keeping footprint, firmware, and sourcing constraints visible.

典型应用
PIC24F08KM101-I/SS 适用于 6 应用s: Industrial Sensor Controller, Battery-Powered Measurement Instrument, Compact Consumer Appliance Control, Threshold Detection and Signal Conditioning, Low-Speed Communication Gateway, Programmable Analog Output Control.
Industrial Sensor Controller
The PIC24F08KM101-I/SS fits industrial sensor controllers because its 16-bit core operates at up to 32 MHz while the integrated 12-bit ADC supports direct analog measurement. Place the controller between a sensor and a low-speed communication or control interface, then use the operating range of 1.8 V to 3.6 V to match the board power architecture. Its -40°C to +85°C ambient rating suits controlled industrial equipment, although the completed product still requires normal EMC and environmental qualification.
推荐
Battery-Powered Measurement Instrument
The PIC24F08KM101-I/SS can serve as the control core of a battery-powered measurement instrument where low-power operation and analog integration are priorities. Its PIC24F XLP architecture, 1 KB RAM, and 512-byte EEPROM support short acquisition workflows and retained configuration data. The 12-bit ADC can acquire sensor signals while the DAC and op amps support excitation or signal conditioning, reducing component count. The principal design constraint is the 1.8 V to 3.6 V operating range of the exact device.
推荐
Compact Consumer Appliance Control
The PIC24F08KM101-I/SS is appropriate for compact consumer appliance control boards that combine digital logic with a few analog measurements. Its 32 MHz processing speed provides margin for control tasks, while the integrated ADC, comparator, DAC, and op amps can replace several discrete analog components. The 20-SSOP package supports space-conscious through-hole-style PCB assembly, and the -40°C to +85°C rating covers many indoor product environments. Firmware should account for peripheral multiplexing and brownout behavior.
推荐
Threshold Detection and Signal Conditioning
The PIC24F08KM101-I/SS is useful in threshold-detection and signal-conditioning products because its comparator can evaluate input levels while the 12-bit ADC supports more detailed measurements. The integrated DAC can generate a reference or test signal, and the op amps can support conditioning around the sensor front end. In implementation, check which analog functions are simultaneously available on each pin and avoid assuming that all peripherals can operate concurrently.
推荐
Low-Speed Communication Gateway
The PIC24F08KM101-I/SS can support a low-speed communication gateway that must also monitor analog inputs. Its 16-bit architecture and 32 MHz clock are suitable for protocol handling and control tasks, while the 8 KB Flash program memory accommodates embedded firmware and the 1 KB RAM supports working buffers. Available communication peripherals and their multiplexing should be confirmed in the family documentation. The 20-SSOP package simplifies assembly where a very small leadless footprint is unnecessary.
推荐
Programmable Analog Output Control
The PIC24F08KM101-I/SS fits programmable analog-output controls that require a DAC, ADC monitoring, and digital control in one package. Firmware can update the DAC output, monitor the result through the ADC, and respond through the available digital I/O. This integration can reduce board area in educational, laboratory, and light-industrial control products. Because SSOP pins are densely assigned and several functions are multiplexed, finalize pin planning before routing the PCB and verify output behavior over the full 1.8 V to 3.6 V supply range.

关键差异点
- Maintains the target MCU configuration in the same package （对比 PIC24F08KM101-E/SS)
- Offers a familiar PIC24F KM migration path （对比 PIC24F08KM100-I/SS)
- Combines multiple analog functions with a 32-bit-class control core （对比 PIC24F08KM100-E/SS)
设计说明
Place the required decoupling capacitor adjacent to the device supply pins and provide a short, low-impedance return path to the ground reference. Keep analog inputs and comparator inputs away from switching-node copper and high-current LED or motor return paths. SSOP lead spacing makes assembly accessible, but the two rows of leads still require careful fanout planning so analog traces do not cross unrelated digital activity.
Design the supply for the exact 1.8 V to 3.6 V operating range rather than the broader 1.8 V to 5.5 V range stated for the PIC24F KM family. Check brownout behavior, ADC accuracy, oscillator startup, and output logic levels at the minimum voltage. If the board also carries sensors or communication devices, ensure their levels remain compatible when the MCU rail falls during a transient or shutdown event.
Do not assume every integrated analog function can operate simultaneously or that all adjacent pins may be assigned to the same peripheral. Build the pin plan from the manufacturer pin-description table, then confirm programming, clock, reset, and programming-interface pins in the final schematic. For a KM100-based substitution, compare the complete peripheral map because a shared package alone does not guarantee identical analog or communication functions.
合规信息
The -I suffix identifies the industrial-temperature grade, but it is not an AEC-Q100 automotive qualification. No explicit RoHS, REACH, halogen-free, or conflict-minerals declaration was established for this exact ordering code.
