PIC24FJ64GA002-I/SP - 16-Bit 64KB MCU | Microchip
部品番号: PIC24FJ64GA002-I/SP ✓ 生産中PIC24FJ64GA002-I/SP 概要
A microcontroller is a programmable control component that integrates a processor core, memory, and peripherals on one semiconductor device. The PIC24FJ64GA002 belongs to the PIC24F family, which combines a 16-bit RISC architecture with general-purpose embedded-system features. Its position within the hierarchy is microcontroller, embedded processor, programmable controller, and semiconductor. Compared with an 8-bit MCU, the 16-bit architecture provides greater arithmetic width while retaining a compact, cost-conscious control design.
Key features include 64 KB of program Flash, 8 KB of data RAM, 21 I/O pins, and a 32 MHz maximum clock indication. The hardware multiplier supports efficient multiplication operations, while the hardware divider accelerates 32-bit-by-16-bit division. The MCU is intended for 2.5 V and 3.3 V operation and is available in a tube-packaged 28-pin SPDIP format for through-hole industrial and embedded assemblies.
The PIC24F architecture supports a C-compiler-optimized instruction set and single-cycle execution, according to the family datasheet listing. This combination makes the device suitable for control loops, signal conditioning, protocol handling, and system management where a compact 16-bit processing engine is preferable to a larger host processor. Its 64 KB Flash capacity also provides room for application code, configuration data, and field-upgrade logic in moderately complex embedded products.
Typical applications include industrial control panels, environmental monitoring, data-acquisition front ends, programmable logic controllers, building controls, and compact embedded instruments. The 21 available I/O pins allow the MCU to connect digital sensors, switches, indicators, communications interfaces, and external interface circuits without requiring a large external expansion controller.
For PCB and firmware planning, confirm the exact pin assignments, peripheral multiplexing, oscillator requirements, and programming connections in the Microchip datasheet and pin-description tables. The 28-pin SPDIP format simplifies prototyping and through-hole assembly, but it requires sufficient board spacing and appropriate handling around the leads.
This product page consolidates the exact PIC24FJ64GA002-I/SP identifiers, manufacturer specifications, package details, search-oriented technical guidance, and practical replacement analysis. It also distinguishes directly compatible alternatives from package or temperature-grade variants that require a different footprint or qualification review.

主な用途
PIC24FJ64GA002-I/SP の用途: 6 件s: Industrial Control Panels, Environmental Monitoring, Data-Acquisition Front Ends, Building and HVAC Controls, Programmable Logic Controllers, Programmable Test and Measurement.
Industrial Control Panels
The PIC24FJ64GA002-I/SP fits industrial control panels that require local logic, human-interface inputs, and device supervision in one package. Its 16-bit RISC core operates up to 32 MHz and reaches up to 16 MIPS, allowing the controller to execute acquisition routines, debounce inputs, and manage output states without an external host processor. With 21 I/O pins, 64 KB of Flash, and 8 KB of RAM, the MCU can support switches, indicators, relays, and digital sensors while retaining application code and operating data on-chip.
おすすめ
Environmental Monitoring
The PIC24FJ64GA002-I/SP is suitable for environmental monitoring equipment that combines digital sensors, local sampling, and communications in a compact controller. The 16-bit processing width and 32 MHz maximum clock support responsive sampling and filtering, while the 17 x 17 hardware multiplier and 32-bit x 16-bit hardware divider accelerate common arithmetic operations. Its 8 KB RAM provides working space for measurements and buffers, and the 64 KB Flash accommodates acquisition, calibration, threshold, and communications firmware.
おすすめ
Data-Acquisition Front Ends
The PIC24FJ64GA002-I/SP can serve as the control layer for a compact data-acquisition front end that accepts digital sensor outputs and performs scaling, filtering, and packet preparation. Operation up to 32 MHz and up to 16 MIPS provide useful processing margin for interrupt-driven acquisition and communications routines. The 21 I/O pins reduce the need for additional expansion logic, while 64 KB of Flash and 8 KB of RAM provide dedicated code and data resources for calibration tables, sample buffers, and protocol handling.
おすすめ
Building and HVAC Controls
The PIC24FJ64GA002-I/SP is well suited to decentralized building-control nodes that monitor inputs and operate local outputs under a programmed control schedule. Its 21 I/O pins can connect switches, sensors, alarm inputs, and actuator-driver interfaces while the 16-bit core handles logic, timing, and state transitions. The 32 MHz clock and hardware arithmetic blocks improve responsiveness without requiring a larger processor, and the 28-pin SPDIP package supports serviceable through-hole controller assemblies with 64 KB of embedded program storage.

Programmable Logic Controllers
The PIC24FJ64GA002-I/SP can implement compact PLC-like logic for machines, test fixtures, and production equipment. Its 16-bit RISC core executes up to 16 MIPS at 32 MHz, providing deterministic handling of interlocks, counters, timers, alarms, and sequential operations. The 21 I/O pins support field inputs and outputs, while the hardware multiplier and divider reduce execution overhead for scaling, measurement, and compensation routines. The through-hole 28-pin SPDIP package also simplifies prototype and maintenance-board construction.

Programmable Test and Measurement
The PIC24FJ64GA002-I/SP is appropriate for compact programmable test equipment where sequencing, measurement conditioning, and instrument control must share one microcontroller. Single-cycle instruction execution and operation up to 32 MHz support time-sensitive control tasks, while the 17 x 17 multiplier and 32-bit x 16-bit divider assist scaling and calibration computations. The device provides 64 KB of Flash for test routines and 8 KB of RAM for temporary data, with 21 I/O pins for front-panel controls and external test-interface connections.

設計ノート
Assign tracks from the manufacturer pin-description table for the 28-pin SPDIP package. Confirm multiplexed functions, power and ground pins, oscillator assignments, and programming connections before layout release. Maintain a clear soldering and inspection area around the through-hole leads, and verify component clearances against the actual package drawing rather than relying solely on the nominal 28-pin outline.
Plan the supply rail for 2.5 V or 3.3 V operation as stated in the device specification. Place local decoupling capacitors close to the device power pins and return their grounds through the shortest practical path. Because no regulator, capacitor, or operating-current values were identified, determine the required supply margin and capacitor values from the Microchip electrical-characteristics and recommended-application sections before schematic release.
Do not treat the industrial and extended ordering codes as unconditional equivalents. PIC24FJ64GA002-I/SP and PIC24FJ64GA002-E/SP use the same base device and SPDIP package, but their temperature-grade suffixes identify different environmental requirements. Review the programmed configuration, brownout behavior, operating limits, and qualification constraints in the manufacturer documentation before replacing one ordering option with the other.
Place oscillators, sensitive measurement inputs, programming interfaces, and communication lines away from high-current switching nodes. The 21 I/O pins provide flexibility, but selected functions can have analog, digital, or peripheral multiplexing requirements that constrain placement. Review the package pin table during schematic partitioning and keep oscillator routing short, symmetrical, and over a continuous ground reference where practical.
