PIC24F08KM202-E/SS - 32MHz XLP Microcontroller | Microchip
MPN: PIC24F08KM202-E/SS ✗ Cuối đờiPIC24F08KM202-E/SS Tóm tắt
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals in one integrated circuit. The PIC24F08KM202 belongs to the PIC24F family of 16-bit microcontrollers and is positioned for compact embedded-control systems. It connects this hierarchy of PIC24F XLP devices, low-power embedded controllers, embedded processing systems, and general-purpose semiconductors.
The principal features of this device include its 32 MHz maximum operating frequency, 8 KB Flash memory organized as 2.75K × 24 words, 2 KB data RAM, and 512 bytes of EEPROM. Communication interfaces include I2C, SPI, IrDA, LINbus, UART, and USART. The integrated 12-bit ADC, 8-bit DAC, and op amps reduce the need for external analog components in compact sensor, control, and signal-conditioning designs.
The PIC core architecture provides a 16-bit processing environment in a low-pin-count device. Flexible capture, compare, and PWM modules support timing and motor-control functions, while the configurable logic cell extends peripheral flexibility without requiring additional external logic. The broad interface set allows the MCU to connect sensors, displays, transceivers, and other embedded peripherals through a limited number of pins.
Typical applications include industrial sensor nodes, building-control equipment, low-power instrumentation, motor and lighting control, battery-operated portable products, and compact consumer devices. The 1.8 V to 3.6 V operating range is particularly useful for energy-efficient systems that cannot accommodate the higher voltage required by many conventional microcontrollers.
Designers should verify analog-input limits, peripheral pin multiplexing, and maximum operating frequency against the manufacturer datasheet before finalizing the PCB. The 28-SSOP package requires careful lead spacing and adequate assembly clearance, and low-power designs should evaluate sleep modes, peripheral activity, and analog-conversion timing rather than relying only on the maximum clock frequency.
This page combines the device architecture, memory and analog capabilities, interface options, application guidance, package constraints, and verified lifecycle information to support faster component selection. It also separates electrically useful selection factors from mechanical redesign requirements so engineers can determine whether a proposed replacement is genuinely board-compatible.

Ứng dụng tiêu biểu
PIC24F08KM202-E/SS phù hợp cho 6 Áp dụngs: Industrial Sensor and Condition Monitoring, Battery-Operated Portable Instrument, Low-Voltage Motor and PWM Control, Building Control and HVAC Peripheral, LED Lighting Control, Low-Power Communications Bridge.
Industrial Sensor and Condition Monitoring
The PIC24F08KM202-E/SS fits compact condition-monitoring systems that acquire analog sensor data while operating from a low-voltage supply. Its integrated 12-bit ADC reduces the need for a separate converter, while the 32 MHz PIC core supports signal filtering, sampling control, local decision-making, and data logging. I2C and SPI provide practical links to temperature, pressure, acceleration, and environmental sensors. The 8 KB Flash and 2 KB RAM are appropriate for focused embedded firmware rather than large data buffers, so application code should use compact buffering and interrupt-driven acquisition. The 1.8 V to 3.6 V operating range also supports energy-conscious industrial equipment when the complete sensor chain can operate within those limits.

Battery-Operated Portable Instrument
The PIC24F08KM202-E/SS is appropriate for compact battery-powered instruments because its PIC24F KM architecture emphasizes low-power operation and supports a 1.8 V to 3.6 V supply. The integrated 12-bit ADC and 8-bit DAC can support measurement, calibration, stimulus generation, and control functions without adding multiple analog ICs. A 32 MHz clock provides sufficient processing performance for responsive user-interface and measurement logic, while the 2 KB RAM and 8 KB Flash encourage an efficient event-driven firmware structure. Designers should determine actual battery life from sleep-mode settings, ADC conversion frequency, display activity, and communication duty cycle rather than from maximum CPU frequency alone.

Low-Voltage Motor and PWM Control
The PIC24F08KM202-E/SS can serve as the controller in small low-voltage motor, solenoid, or actuator systems because its flexible capture, compare, and PWM modules suit deterministic timing functions. The 32 MHz processor can execute closed-loop control, current or position monitoring, fault handling, and communication updates. The integrated 12-bit ADC allows analog feedback to be sampled without adding a separate converter, while I2C, UART, and USART provide paths to sensors, supervisory controllers, and service interfaces. Designers should size external drive transistors and protection networks independently, verify PWM and capture behavior in the datasheet, and account for inductive voltage transients that are outside the MCU supply rails.

Building Control and HVAC Peripheral
The PIC24F08KM202-E/SS is suitable for building-control peripherals that combine sensing, local actuation, and low-speed serial communication. Its integrated ADC can monitor environmental or analog system conditions, while the DAC and op amps support signal generation or conditioning in compact modules. I2C is well suited to sensor hubs, SPI supports higher-speed peripherals, and LINbus, UART, or USART can connect the module to a controller network. The 1.8 V to 3.6 V range permits integration with low-voltage power trees, and the 28-SSOP package supports space-constrained equipment. Firmware should implement watchdog recovery, communication fault handling, and power-state transitions to improve field reliability.

LED Lighting Control
The PIC24F08KM202-E/SS can implement compact LED lighting control with dimming, status indication, and communication. Its PWM-related timing resources support adjustable LED drive, while the integrated ADC can monitor a current or supply sense signal, and the 8-bit DAC can generate simple analog references or test waveforms. SPI and I2C allow connection to LED drivers, color controllers, or configuration memories. Because the MCU does not directly replace a power MOSFET driver, an external transistor or dedicated LED-driver circuit must handle current and voltage levels. Validate duty-cycle resolution, update latency, thermal conditions, and EMI behavior before using the device in a high-current lighting product.
Được đề xuất
Low-Power Communications Bridge
The PIC24F08KM202-E/SS can act as a compact protocol bridge or embedded communications controller when a system needs to translate among UART, USART, I2C, SPI, IrDA, or LINbus signals. Its 32 MHz PIC core supports protocol handling, buffer management, and status reporting, while 2 KB of RAM is suitable for modest frame processing. The integrated ADC and DAC can support diagnostic measurements or test functions, reducing the component count of a service interface. For production designs, prioritize deterministic interrupt latency, correct peripheral multiplexing, and careful assignment of UART and I2C pins in the 28-SSOP package. Because the MCU is obsolete, a new long-lived communications product should include a planned migration to a currently supported family.

Ghi chú thiết kế
Design the power tree around the 1.8 V to 3.6 V operating range of PIC24F08KM202-E/SS. Place the required bypass capacitors close to the supply and ground pins, use a low-impedance ground reference, and verify external sensor or communication devices for logic-level compatibility. Review the manufacturer pin-description table for analog, digital, and power pins before assigning functions, because the 28-SSOP footprint provides less routing flexibility than larger packages.
Treat the 28-SSOP package as a constrained assembly footprint. Confirm land pattern dimensions against the manufacturer package drawing, support the leads during reflow, and maintain adequate clearance from surrounding components. Check every peripheral signal against the multiplexing table rather than assuming adjacent pins are dedicated functions. A PCB change to another package should be treated as a redesign because pin mapping, courtyard, solder process, and assembly requirements may all change.
Do not base an exact replacement on family naming alone. The package suffix, pin multiplexing, peripheral set, memory configuration, voltage limits, and software device identifier must all be compatible. For an existing PIC24F08KM202-E/SS board, a candidate with the same 28-SSOP package should still be checked against the manufacturer pin table and errata. Verify ADC reference, DAC output, oscillator, and peripheral timing requirements before approving a substitution.
The principal thermal concern is the dissipation associated with the selected supply voltage and operating frequency rather than a single isolated regulator specification. At 32 MHz, control clock gating, peripheral activity, and the duty cycle determine average power. Use the manufacturer power-management guidance to select sleep modes and peripheral shutdown states. Validate the enclosure temperature and nearby component heating during the worst operating mode, especially in sealed industrial equipment.
