PIC24FJ32GA002-E/SO 概要
What is a PIC24F microcontroller? PIC24F is Microchip's 16-bit general-purpose MCU family, positioned between the 8-bit PIC16/PIC18 lines and the 32-bit PIC32 line within the broader microcontroller taxonomy (microcontroller -> embedded MCU -> 16-bit MCU -> PIC24F family). It uses a modified Harvard architecture with a C-optimized instruction set, single-cycle hardware multiply (17 x 17), single-cycle hardware 32/16 divider, and the nanoWatt power-management technology. Designers select PIC24F when 8-bit MCUs lack the MIPS/heap headroom but full PIC32 is over-budget.
Key features include a 10-bit ADC, multiple serial interfaces (2x UART, 2x SPI, 2x I2C), five 16-bit timers, and configurable I/O pins with peripheral pin select. The 28-SOIC footprint suits hand-soldered prototypes and through-friendly SMT assembly, while the wider pitch (0.295 in / 7.50 mm) simplifies inspection. Built-in nanoWatt features such as Idle, Sleep, and Doze modes enable battery-friendly designs, and the integrated Real-Time Clock Calendar (RTCC) module reduces external BOM. The 16 MIPS throughput is sufficient for sensored motor control, multi-protocol bridging, and small GUI/HMI layers.
Typical applications include sensor hubs, low-cost HVAC fan controllers, white-goods user-interface boards, and industrial sensor-interface front-ends that require a balance of peripheral count and deterministic response. The wide temperature window also opens automotive interior and industrial cabinet deployments where consumer-grade parts would fail.
When designing with this part, place a 10 uF plus 0.1 uF decoupling pair adjacent to VDD/VSS, keep analog AVSS separated from digital GND, and review the device errata document before committing firmware. The "-E" temperature suffix (extended) is essential when target environments exceed +85C, otherwise the equivalent PIC24FJ32GA002-I/SO (industrial, -40C to +85C) can be considered.

主な用途
PIC24FJ32GA002-E/SO の用途: 6 件s: Sensor Hub and Multi-Protocol Bridge, Automotive Interior and HVAC Controllers, Low-Cost Industrial Sensor Interface, White-Goods User Interface Board, Portable Medical Monitoring (Non-Critical), Educational / Maker Development Platforms.
Sensor Hub and Multi-Protocol Bridge
The PIC24FJ32GA002-E/SO is well-suited to sensor-hub and multi-protocol bridge applications thanks to its 16 MIPS throughput, dual UART/SPI/I2C buses, and 32 KB Flash that comfortably fits Modbus RTU, CAN-style soft controllers, or sensor-fusion glue. With 2.0-3.6 V supply, it can be powered directly from a 3.3 V regulated rail or two AA cells. The five 16-bit timers enable deterministic pulse capture for flow meters or quadrature decoders, while the 10-bit ADC handles up to 16 analog channels typical of environmental sensing. Place this MCU between a UART-connected BLE module and an SPI-attached sensor array; the device's nanoWatt Sleep mode drops current below 5 uA between sample windows, supporting battery-backed industrial sensor installations.
おすすめ
Automotive Interior and HVAC Controllers
The PIC24FJ32GA002-E/SO's "-E" temperature suffix qualifies it to -40C to +125C, ideal for automotive interior and HVAC modules per Microchip's PIC24F automotive positioning. Its 32 KB Flash hosts small real-time HVAC state machines, while 5 PWM channels drive fans or damper motors directly through external FETs. The dual UARTs bridge LIN or K-Line legacy buses with newer CAN-attached body controllers, and the 10-bit ADC reads thermistors and pressure transducers. With 28-SOIC packaging, the part survives the under-dash thermal environment and is hand-solderable for low-volume prototype runs. Pair with a Microchip LIN SBC such as MCP2003B or ATA663231 for a complete HVAC node.
おすすめ
Low-Cost Industrial Sensor Interface
Industrial sensor-interface front-ends benefit from the PIC24FJ32GA002-E/SO's 16 MIPS core, dual UART/SPI/I2C, and 10-bit ADC. Engineers deploy it in 4-20 mA loop converters, photoelectric sensor amplifiers, and weigh-scale signal conditioners. The 32 KB Flash holds Modbus RTU slaves plus calibration tables, while the 8 KB RAM buffers Modbus transaction frames. The 28-SOIC's wide body (0.295 in) simplifies hand rework in the field. Operate from a 24 V -> 3.3 V switching regulator and place the MCU's ADC reference on a precision MCP1525 to keep analog readings accurate to 0.2 percent over industrial -10C to +70C bench temperatures.
おすすめ
White-Goods User Interface Board
White-goods appliances (washing machines, dishwashers, induction cooktops) deploy the PIC24FJ32GA002-E/SO as the user-interface MCU running display scanning, button debouncing, and relay/buzzer actuation. The 5 PWM channels control LED-backlit segment displays and variable-speed buzzers, while the timers manage wash-cycle timing and capacitive-touch sensing. The 32 KB Flash accommodates FreeRTOS-light or MPLAB Harmony Configurator stacks for state-machine UIs. The -40C to +125C rating survives the thermal gradients of front-panel electronics behind cooktops and steam-emitting appliances. Drive seven-segment displays with low-cost SIPO shift registers gated by the SPI peripheral.
おすすめ
Portable Medical Monitoring (Non-Critical)
Battery-powered home-health monitors such as pulse-oximeter docks, nebulizer timers, and pill-dispenser alarms use the PIC24FJ32GA002-E/SO as a low-power MCU with deterministic IO. The 2.0-3.6 V supply aligns with single-cell Li-ion, and nanoWatt Sleep at <5 uA keeps the device alive for months between user interactions. The 32 KB Flash fits small BLE-host framing logic plus eeprom-backed event logs. Note: this is a general-purpose MCU; for any Class I/II/III medical device requiring IEC 60601-1 or ISO 13485 compliance, escalate to a PIC24FJ256GBxxx or dsPIC33 with safety-documentation package.
おすすめ
Educational / Maker Development Platforms
The PIC24FJ32GA002-E/SO powers university microcontroller courses, makerspace projects, and HobbyPIC-style dev kits thanks to its 28-SOIC footprint (hand-solderable) and 32 KB Flash (room for substantial demo firmware). MPLAB X IDE and the XC16 compiler are free, lowering entry cost. The dual UARTs let students bridge USB-to-UART debug while running application code, and the 5 PWM channels drive servos or motor drivers in robotics curricula. For a richer teaching platform, the PIC24FJ32GA002 Plug-In Module (MA240011) on the Explorer 16/32 board enables PIC24, dsPIC33, and PIC32 device swap with one board, ideal for course-labs covering multiple MCU families.

設計ノート
Place a 10 uF bulk capacitor in parallel with a 0.1 uF ceramic decoupling capacitor within 5 mm of the VDD/VSS pins (pins 13/12 and 28/27). For the analog section, AVDD/AVSS (pins 20/19) should have their own 0.1 uF + 10 uF pair if the ADC is used. A ferrite bead between digital VDD and analog AVDD reduces switching-noise coupling into ADC conversions. Estimated: with 32 MHz core and active peripherals, IDD typical is 15-20 mA at 3.3 V; nanoWatt Sleep drops this below 5 uA per Microchip family datasheet.
While the 28-SOIC's theta_JA (~80 C/W typical) is far better than QFN packages, automotive-class ("-E" suffix) designs should still derate under worst-case ambient +125C. Estimated: at 20 mA active current and 3.6 V VDD, internal dissipation is approximately 0.072 W; with 80 C/W theta_JA the junction rise is ~6 C above ambient, leaving comfortable margin. Avoid sealing the MCU inside an enclosed relay box without ventilation, since surrounding ambient may push Tj to 130 C.
Keep analog traces (RA0-RA7, RB8-RB13) short and away from digital switching nodes (PWM outputs, SPI SCK). Use a single-point ground where AVSS ties back to the digital VSS plane near the regulator output. The 28-SOIC's 0.295 in (7.50 mm) body and 1.27 mm pitch allows hand-soldering with a fine tip; use a 100 mil ground fill under the SOIC body to pull heat away. Reserve the RP0-RP9 remappable peripheral pins for peripherals needing flexibility (UART TX/RX, SPI SCK/MISO/MOSI), keeping fixed-function pins free for analog and ICSP.
Always read the Microchip PIC24FJXXXGA0XX errata document (DS80333 or latest revision) before firmware freeze - early silicon revisions had ADC and JTAG bugs. Do not exceed VDD of 3.6 V; PIC24F is a 3.3 V family, NOT 5 V tolerant on all pins. Always issue the unlock sequence (NVMKEY) before Flash self-programming, or the row write will be silently ignored. For ICSP programming, dedicate RB6/RB7 (pins 17/18) to PGD/PGC and isolate them with current-limiting resistors if shared with application circuitry.
