部品番号: PIC24F16KL402-I/MQ ✓ 生産中PIC24F16KL402-I/MQ 概要
A microcontroller is a semiconductor device that integrates a processor core, program memory, data memory, input/output ports, and dedicated peripherals into one compact package. The PIC24F family occupies the low-cost embedded-control segment of the broader microcontroller hierarchy, combining a 16-bit RISC architecture with features familiar to users of PIC18 peripherals. This combination supports migration of cost-sensitive systems that require greater computational capability than an 8-bit platform.
Key features include 16 KB of Flash memory organized as 5.5K x 24 words, 1 KB of SRAM, an additional 512-byte memory resource identified by distributor listings, and a 10-bit ADC. The device operates from a 1.8 V to 3.6 V supply range, supports up to 16 MIPS at 3.3 V, and includes Basic code-guard security. Its nanoWatt XLP feature set targets applications where low power consumption is as important as processing performance.
The PIC24F16KL402 architecture is designed for economical, low-pin-count systems that need more control capability than an 8-bit MCU. Its MSSP peripheral supports I2C or SPI communication, while the CCP/ECCP blocks provide capture, compare, and PWM functions useful in motor, lighting, and signal-generation designs. The 28-QFN 5x5 mm package supports compact layouts, although exposed-pad layout and thermal verification must be considered during PCB design.
Typical applications include portable consumer devices, portable GPS equipment, cell-phone accessories, electronic toys, portable sports products, disposable medical testers, dispensers, inhalers, and safety or security systems. The family data sheet specifically identifies these low-power, low-cost application areas, while the MSSP and CCP/ECCP peripherals support connected sensors, actuator control, and communication interfaces.
When designing around the PIC24F16KL402-I/MQ, verify the 28-QFN land pattern, exposed-pad requirements, and decoupling layout against the manufacturer data sheet. If low-power operation is required, configure the nanoWart XLP modes carefully and validate every peripheral state. The 3.3 V operating point supports 16 MIPS, while operation across the full 1.8 V to 3.6 V range may require the device to operate at a lower frequency.
This product record combines verified manufacturer and distributor specifications with practical low-power design guidance, package considerations, and explicit data gaps. It distinguishes documented parameters from values that must be checked in the complete family data sheet, helping engineers make sourcing and design decisions without treating unverified assumptions as specifications.

主な用途
PIC24F16KL402-I/MQ の用途: 6 件s: Portable Consumer Devices, Portable GPS Equipment, Disposable Medical Testers, Dispensers and Inhalers, Electronic Toys and Games, Safety and Security Systems.
Portable Consumer Devices
The PIC24F16KL402-I/MQ fits portable consumer products that need more processing capability than an 8-bit controller without carrying the cost of a larger MCU. Its 16-bit PIC24F core operates at up to 32 MHz, while 16 KB of Flash and 1 KB of RAM support embedded control logic and firmware. The 1.8 V to 3.6 V operating range accommodates low-voltage portable systems, and nanoWart XLP provides a basis for reducing consumption during idle periods. Designers can use MSSP for I2C or SPI sensors and CCP/ECCP for timing or PWM outputs. The 28-QFN 5x5 mm package also helps limit board area, although its exposed-pad layout must be implemented according to the manufacturer package drawing.
おすすめ
Portable GPS Equipment
The PIC24F16KL402-I/MQ can serve as a low-power control processor in portable GPS equipment where a compact MCU must coordinate user inputs, status indicators, and external interfaces. Its 16-bit architecture and up-to-16-MIPS performance at 3.3 V provide useful headroom for protocol handling, while the 16 KB Flash budget is appropriate for compact embedded firmware. MSSP I2C/SPI connectivity allows communication with an external navigation or memory device, and the CCP/ECCP peripherals support timing functions. Because GPS equipment is frequently battery operated, the MCU's 1.8 V to 3.6 V range and nanoWart XLP capabilities are important. Power-state design and antenna or radio selection remain separate system-level tasks.
おすすめ
Disposable Medical Testers
The PIC24F16KL402-I/MQ is appropriate for disposable, cost-sensitive medical-test equipment where deterministic control, compactness, and low power are priorities. Its 16-bit core provides more computational capability than an 8-bit platform, while the 10-bit ADC supports basic analog measurement functions. The 1 KB RAM and 16 KB Flash are sized for focused diagnostic-control firmware rather than complex data processing. MSSP can connect external sensors through I2C or SPI, and CCP/ECCP can support timing or stimulus-control functions. The 28-QFN 5x5 mm package reduces board footprint in portable formats. Such applications still require manufacturer-specific validation of accuracy, electrical safety, reliability, and applicable medical standards before market release.
おすすめ
Dispensers and Inhalers
The PIC24F16KL402-I/MQ fits compact dispenser and inhaler mechanisms that require precise timing, motor or valve control, and low standby consumption. Its CCP/ECCP peripheral is relevant to repeatable actuation and PWM-related control, while the 16-bit architecture and up-to-16-MIPS operation at 3.3 V allow more responsive control software than an 8-bit alternative. The 1.8 V to 3.6 V supply range supports low-energy designs, and nanoWart XLP can help reduce consumption between user actions. MSSP I2C/SPI can connect a display, sensor, or configuration memory. Mechanical safety, actuator current, battery behavior, and usable capacity must be validated together because the MCU specification alone does not determine the final device performance.
おすすめ
Electronic Toys and Games
The PIC24F16KL402-I/MQ is a practical controller for electronic toys and games requiring responsive interaction, multiple I/O functions, and a low component count. The up-to-32-MHz 16-bit core supports real-time control, while 16 KB of Flash accommodates animation, sound sequencing, or game-state firmware. MSSP can operate in I2C or SPI mode for an external display, sensor, or audio module, and CCP/ECCP supports timing and PWM functions. Its 28-QFN 5x5 mm package helps maintain a compact product layout. The device also fits cost-sensitive designs, one of the family's stated market advantages. Designers should account for exposed-pad soldering, supply decoupling, and input protection when adapting the QFN footprint to a high-volume consumer PCB.
おすすめ
Safety and Security Systems
The PIC24F16KL402-I/MQ can be used in compact safety and security equipment that combines sensor monitoring, timed outputs, and serial communication. Its 16-bit processing capability and 10-bit ADC support more demanding control logic than a basic 8-bit device, while MSSP I2C/SPI permits connection to external detectors, memory, or communication modules. CCP/ECCP provides timing functions suited to alarms, indicators, or controlled actuators. The 1.8 V to 3.6 V operating range allows integration with low-voltage power systems, and nanoWart XLP can reduce standby demand. For security products, the documented Basic code-guard feature supports firmware protection, but designers should evaluate the exact protection level and external threat model rather than assuming that program-memory locking alone secures the complete product.

設計ノート
Implement the 28-QFN 5x5 mm footprint strictly from the package drawing in the manufacturer family data sheet. Confirm whether the exposed center pad is electrically required, its dimensions, and the recommended land pattern before release. Place input and output decoupling capacitors close to their associated supply pins and provide a low-impedance ground return; the supplied excerpts do not include the complete pin table or exact capacitor values.
Use nanoWart XLP only after mapping every peripheral and I/O state into the firmware's sleep plan. Disable unused oscillators, timers, communication interfaces, and digital outputs before entering a low-power mode. The verified device range is 1.8 V to 3.6 V, but the cited 16 MIPS figure applies at 3.3 V; validate the operating frequency and brownout behavior at each actual supply voltage using the complete electrical specifications.
Do not treat PIC24F16KL402 variants in SPDIP, SSOP, or other package suffixes as PCB drop-ins for the MQ order code. The verified target uses a 28-QFN 5x5 mm package, while the cross-reference excerpts identify alternative package options such as -I/SP and -I/SS. Also confirm the meaning of the T, I, and MQ ordering segments against the manufacturer ordering table before approving a substitution or production BOM.
コンプライアンス情報
The supplied verified excerpts do not state the requested compliance statuses. The exact MPN includes an industrial-temperature ordering segment, but the provided materials do not explicitly identify AEC-Q100 qualification, so it is recorded as unknown.
