PIC24F08KM101-E/SO - 32MHz 8KB 16-Bit MCU | Microchip
N.º da peça: PIC24F08KM101-E/SO ✓ AtivoPIC24F08KM101-E/SO Visão geral
A PIC XLP microcontroller is a low-power embedded controller combining a 16-bit RISC core, digital peripherals, analog conversion functions, and communications interfaces in one integrated circuit. It belongs to the PIC24F family of 16-bit microcontrollers, where low-power design and a small pin count suit compact control, sensing, and communication products.
Principal features include a 32 MHz maximum operating speed, 8 KB of Flash organized as 2.75K × 24 words, 1K × 8 bits of RAM, and 512 × 8 bits of EEPROM. The device supports operation from 1.8 V to 5.5 V and integrates a 12-bit ADC, comparator, and flexible capture, compare, and PWM modules. Communication capabilities include I2C, SPI, UART/USART, IrDA, and LINbus support.
The 20-pin architecture concentrates mixed-signal and control resources into a compact package. Its 12-bit ADC supports embedded measurement, while the comparator can perform threshold detection without a separate analog device. The integrated EEPROM provides nonvolatile parameter storage, and the 8 KB Flash region accommodates control firmware and application code within the constraints of a small low-power design.
Typical applications include industrial sensor controllers, compact motor and actuator controls, battery-powered instruments, communications modules, LED lighting controllers, and compact consumer appliances. The combination of low pin count, 1.8 V to 5.5 V operating range, and multiple serial interfaces makes the PIC24F08KM101-E/SO appropriate for designs that need flexible embedded control without a high pin-count package.
During PCB design, assign analog, power, ground, and programming pins according to the manufacturer pin-description table, and verify the external decoupling and oscillator requirements for the selected configuration. Firmware should also account for the peripheral mix and electrical limits associated with the exact PIC24F KM variant before production release.

Aplicações típicas
PIC24F08KM101-E/SO é adequado para 6 aplicaçãos: Industrial Sensor Controller, Battery-Powered Measurement Instrument, Compact Motor and Actuator Control, Communications Module, LED Lighting Controller, Consumer Appliance Control.
Industrial Sensor Controller
The PIC24F08KM101-E/SO fits compact industrial sensing equipment that needs local analog measurement, deterministic control, and serial connectivity. Its integrated 12-bit ADC can acquire sensor signals, while the comparator can implement a hardware threshold event without continuous software polling. The 32 MHz CPU supports responsive control logic, and the 1 KB RAM provides working space for measurements and communication buffers. I2C and SPI provide options for connecting sensors and programmable logic, while UART/USART supports service consoles or upstream controllers. Its 1.8 V to 5.5 V operating range accommodates industrial rails, and the -E temperature-grade option suits extended-temperature equipment.
Battery-Powered Measurement Instrument
The PIC24F08KM101-E/SO is appropriate for a battery-powered measurement instrument where processing capability must be balanced against low-power operation. The PIC24F KM family uses nanoWatt eXtreme low-power technology, and the device integrates a 12-bit ADC, comparator, EEPROM, and multiple communications interfaces. The 8 KB Flash stores firmware, while 1 KB of RAM supports short acquisition and processing buffers; the 512-byte EEPROM can retain calibration or configuration data. For a compact design, the 20-pin SOIC footprint leaves board area for the sensor, power conversion, and battery conditioning.
Compact Motor and Actuator Control
The PIC24F08KM101-E/SO can serve as the control core in a small motor or actuator module because it combines 32 MHz processing with flexible capture, compare, and PWM resources. Timers can generate deterministic control waveforms, while the 12-bit ADC and comparator support current, position, temperature, or limit sensing. The 20-pin SOIC package provides a compact footprint for equipment where space is constrained. Designers should allocate pins according to the exact peripheral mapping, select an appropriate external driver for the load, and verify that PWM and communication activity remain compatible with the device's operating and temperature limits.
Communications Module
The PIC24F08KM101-E/SO suits a low-pin-count communications module requiring several host-facing interfaces. I2C supports short-distance sensor and configuration buses, SPI supports higher-speed peripherals, and UART/USART, IrDA, and LINbus options broaden its applicability in industrial links, remote controls, and optically isolated serial links. The 32 MHz core can handle protocol processing and local control, while 8 KB Flash and 1 KB RAM provide space for compact embedded firmware. The 1.8 V to 5.5 V range permits integration with both low-voltage and 5 V interface ecosystems, subject to each peripheral's supply requirements.
LED Lighting Controller
The PIC24F08KM101-E/SO is well suited to a compact LED lighting controller because its capture/compare/PWM resources can generate dimming and sequencing signals while the 12-bit ADC can monitor a current or illumination feedback channel. The comparator can provide fast fault or threshold detection, and the integrated EEPROM can retain lighting scenes and calibration settings. With 32 MHz processing, the controller can combine feedback regulation, user-interface handling, and communications without using a higher-pin-count MCU. The 20-pin SOIC package reduces board size, while the -E temperature-grade option supports extended industrial environments.
Consumer Appliance Control
The PIC24F08KM101-E/SO can serve as the embedded controller in a compact appliance that combines local buttons, a sensor, and an actuator. The 12-bit ADC handles analog controls or condition monitoring, the comparator supports simple limit detection, and the serial interfaces allow connection to a display, module, or service adapter. Its 1 KB RAM and 8 KB Flash are sufficient for compact control code but require deliberate allocation if the product stores user data or complex sequences. The 20-pin SOIC package supports automated assembly and board-space reduction, while 1.8 V to 5.5 V operation provides flexibility in low-voltage accessory designs.

Notas de projeto
Design the supply network for the full 1.8 V to 5.5 V operating range and place the required bypass capacitors close to the device power pins. Separate analog and digital return paths where the board architecture permits, and route high-current switching-node copper away from ADC and comparator inputs. Confirm the voltage limits of every connected sensor and communication peripheral because an individual interface may not tolerate the complete MCU supply range.
Use the manufacturer package drawing and pin-description table when assigning the 20-pin SOIC footprint. Preserve access to programming and debug functions in the production layout, maintain adequate clearance around analog inputs, and avoid routing fast communication or PWM signals parallel to sensitive measurement traces. If the internal oscillator is used, follow the recommended layout and decoupling arrangement to reduce sensitivity to switching noise and temperature.
Do not substitute an -I/SO or T-I/SO device for the automotive -E/SO option without accepting the lower temperature-grade requirement. Also verify peripheral assignments before choosing PIC24F08KM100 or PIC24F08KM102 alternatives. The shared 20-pin footprint and 32 MHz architecture make these devices attractive drop-in candidates, but changes in analog, communications, or timer resources can still alter firmware and board requirements.
Keep I2C, SPI, UART/USART, IrDA, and LINbus routing away from ADC and comparator inputs, especially when switching supplies or PWM outputs share the board. Apply the manufacturer's recommended pull-up values for communication interfaces, keep traces short where bus capacitance is significant, and provide a defined ground reference for each interface. For sensor measurements, evaluate source impedance and acquisition timing because the 12-bit converter does not remove errors caused by an unsuitable signal source or poorly conditioned reference.
Informações de conformidade
The -E/SO ordering option is identified as automotive temperature grade, but no explicit AEC-Q100 qualification or environmental-compliance statement is present. These fields remain unknown rather than being inferred from the temperature suffix.
