PIC24F08KL402-I/MQ - 32MHz 16-Bit MCU | Microchip Technology
N.º da peça: PIC24F08KL402-I/MQ ✓ AtivoPIC24F08KL402-I/MQ Visão geral
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. The PIC24F08KL402 belongs to the PIC24F family of 16-bit Flash microcontrollers, which sits within the broader embedded-controller and semiconductor hierarchy. Its nanoWatt XLP technology supports low-power operating modes intended for battery-powered or intermittently powered products where reducing energy consumption is important.
Key features include 8 KB of Flash for firmware storage, 1 KB of SRAM for working data, 512 bytes of EEPROM for nonvolatile parameters, 17 I/O ports, and a 10-bit ADC. The MSSP peripheral supports I2C or SPI communication, while the CCP and ECCP modules add capture, compare, and PWM capabilities. These resources allow the device to consolidate functions that might otherwise require separate interface and timing components.
The device operates from 3 V to 3.6 V and can run at up to 32 MHz. Its 16-bit architecture provides a practical balance between computational capacity, memory efficiency, and implementation cost for general-purpose control. The -I/MQ package combines a compact 5x5 mm QFN footprint with 17 available I/O pins, making it appropriate for space-constrained control boards that require several digital interfaces and analog measurement channels.
Typical applications include industrial sensor nodes, compact motor-control modules, cost-sensitive data acquisition units, low-power environmental monitors, and small appliance controllers. An I2C bus can connect the MCU to a sensor or display, SPI can support higher-speed peripherals, and the ADC can read analog inputs. For designs requiring additional memory, pin count, or specialized peripherals, a larger member of the PIC24F family may be a better fit.
Designers should verify the complete QFN-28 pin assignment, exposed-pad connection, decoupling requirements, and peripheral multiplexing against the manufacturer documentation before layout. The 3 V to 3.6 V supply range also requires regulators and signal levels that remain compatible with 3.3 V peripherals. Software configuration should avoid assuming that every peripheral can operate simultaneously because pin multiplexing and shared resources can constrain valid combinations.
This page consolidates the verified device specifications, sourcing information, package details, lifecycle status, and honest replacement analysis in one place. It also distinguishes a genuine same-package electrical option from variants that cannot be treated as drop-in replacements, helping engineers make PCB-compatible design decisions without relying on assumptions.

Aplicações típicas
PIC24F08KL402-I/MQ é adequado para 6 aplicaçãos: Industrial Sensor and Measurement Node, Cost-Sensitive Motor and Actuator Control, Low-Power Environmental Monitor, Compact Appliance and User Interface Controller, Battery-Powered Portable Data Acquisition, Communication Interface and Protocol Bridge.
Industrial Sensor and Measurement Node
The PIC24F08KL402-I/MQ fits compact industrial measurement nodes that combine analog sensing with local processing and communication. Its 10-bit ADC supports moderate-resolution process measurements, while 8 KB of Flash provides room for control logic, calibration routines, and a communication state machine. The MSSP peripheral can connect a sensor or external data-acquisition device through I2C or SPI, and 17 I/O ports provide discrete digital connections. Operating from 3 V to 3.6 V supports 3.3 V system architecture, although an industrial enclosure, surge protection, sensor excitation design, and calibration strategy remain outside the MCU. The 28-QFN 5x5 mm package also allows a small controller board, but exposed-pad layout and thermal conditions must follow the manufacturer package requirements.
Cost-Sensitive Motor and Actuator Control
The PIC24F08KL402-I/MQ is appropriate for small motor, valve, relay, or actuator-control modules where the firmware must combine timing logic with low-cost communications. Its CCP and ECCP peripherals can support capture, compare, and PWM workflows, while the 32 MHz maximum clock provides timing headroom for control tasks. The 1 KB SRAM and 8 KB Flash are sufficient for focused control firmware without a larger microcontroller package. A 3 V to 3.6 V supply simplifies integration with 3.3 V gate drivers and sensors. Designers should confirm the required PWM resolution, duty-cycle range, fault-handling latency, and whether motor transients exceed the MCU’s verified supply limits. Current sensing, protection, and grounding must be designed around the motor environment rather than assumed to be handled by the controller.
Low-Power Environmental Monitor
The PIC24F08KL402-I/MQ suits battery-operated environmental monitors because the PIC24F08KL402 family combines a 16-bit controller with nanoWatt XLP low-power technology. The device can periodically wake, sample a sensor, update state, and return to a low-power operating condition, while its 512-byte EEPROM can retain limited configuration or calibration information between sessions. I2C is useful for compact environmental sensors, whereas SPI can support higher-throughput sensor or external storage devices. The 10-bit ADC can also read simple analog sensing networks directly. Battery-life calculations must include sensor standby current, regulator quiescent current, wake timing, and the interval between samples. The 3 V minimum supply may require a boost or buck-boost arrangement for common single-cell batteries, while a 3.3 V cell can simplify the power tree.
Compact Appliance and User Interface Controller
The PIC24F08KL402-I/MQ can serve as the local controller in a compact appliance, panel, or user-interface module where a display, keys, indicators, and one or two sensors share a small board. Its 17 I/O ports can support discrete inputs and outputs, while MSSP provides a practical path to an I2C display or I2C/SPI peripheral. The 10-bit ADC is useful for potentiometers, temperature sensing, or simple analog feedback, and 8 KB of Flash accommodates menu logic, state management, and device control. The 28-QFN 5x5 mm footprint reduces board area compared with larger leaded packages. Designers must carefully assign multiplexed functions and account for LED driver load, display voltage requirements, debounce strategy, and brownout behavior. The MCU does not remove the need for appropriate level shifting or transistor drivers.
Battery-Powered Portable Data Acquisition
The PIC24F08KL402-I/MQ is well matched to a small, portable data-acquisition module that records a small number of analog channels and transfers data to a host. The 10-bit ADC handles moderate-resolution sampling, the 1 KB SRAM supports buffering and working calculations, and the 8 KB Flash stores firmware and configuration logic. I2C or SPI can connect a sensor, external memory, or communication module through MSSP. nanoWatt XLP technology enables duty-cycled operation, which is valuable when the unit must consume little energy between measurement intervals. Sampling rate, memory depth, and simultaneous peripheral use determine whether the 32 MHz clock is sufficient. The 3 V to 3.6 V supply range must be coordinated with battery chemistry, charge circuitry, and front-end sensor excitation. Signal conditioning and input protection also require separate engineering beyond the MCU.
Communication Interface and Protocol Bridge
The PIC24F08KL402-I/MQ can implement a compact protocol bridge or embedded communications controller for a sensor, actuator, or legacy equipment interface. MSSP supports I2C or SPI on the host-facing side, while the available GPIO can connect additional control signals or another peripheral interface. The 32 MHz PIC24F core provides processing capacity for framing, validation, buffering, and protocol conversion, and the 512-byte EEPROM can hold a limited configuration profile. For industrial equipment, the industrial-grade ordering option is the relevant baseline, but enclosure temperature, isolation, ESD protection, and ground-noise control still require system-level design. Verify the exact UART availability, pin multiplexing, timing tolerances, and peripheral resource conflicts against the complete device documentation. Firmware should include timeout and recovery behavior for disconnected or noisy buses.

Notas de projeto
Design the supply network for the verified 3 V to 3.6 V operating range. Place the required local decoupling capacitors at the device supply pins, keep the supply return path short, and isolate noisy switching or motor-current paths from the controller. The maximum 32 MHz clock does not determine the required current by itself; actual demand depends on operating mode, peripheral activity, and I/O loading. Review the manufacturer electrical characteristics and exposed-pad connection before finalizing the regulator and capacitor selection.
Use the manufacturer’s 28-QFN 5x5 mm land pattern and thermal-pad guidance rather than a generic QFN footprint. The supplied records establish the package size and pin count but do not provide the full pad geometry, so dimensions, mask tolerances, and exposed-pad vias must be taken from the official package drawing. Confirm every pin function and alternate-function mapping in the datasheet before routing. Incorrect orientation or exposed-pad treatment can prevent operation or increase local heating.
Do not treat package similarity alone as proof of drop-in compatibility. PIC24F08KL402-I/MQ and PIC24F08KL402-E/MQ have matching listed electrical ratings and the same 28-QFN package, but their temperature-grade ordering differs. By contrast, the -I/SS and -I/ML variants use different packages and cannot be installed on the target footprint. Also verify pin multiplexing before assigning MSSP, CCP, and ECCP functions because these peripherals can share I/O resources.
Keep analog ADC inputs away from high-current switching nodes and digital clock nets. Use a compact, quiet ground return around the MCU, route I2C and SPI signals according to rise-time and capacitance considerations, and avoid long unprotected traces that can couple motor or display noise into measurement channels. The 10-bit ADC should be paired with suitable input conditioning, and any external reference or sensor supply should have its own local bypass path. These layout choices are particularly important in compact industrial or appliance products.
