PIC24FJ64GB002-I/SP 개요
What is a PIC24F microcontroller? A PIC24F is a 16-bit modified Harvard RISC microcontroller from Microchip's PIC24 family that bridges 8-bit PIC microcontrollers and 32-bit PIC32 devices, offering higher performance (up to 16 MIPS) and richer peripherals (USB OTG, CTMU, comparators) while retaining the low-power eXtreme Low Power (nanoWatt XLP) features of the PIC16/18 product lines. It sits in the hierarchy: PIC24F -> 16-bit MCU -> Microcontroller -> Semiconductor. The 'FJ' family specifically targets low-power USB applications.
Key features include a hardware USB 2.0 Full-Speed OTG controller with internal transceiver, two I²C, two SPI, and two UART interfaces for simultaneous communication, five 16-bit PWM channels with seven timer modules, three analog comparators, a 10-bit ADC, and a Charge Time Measurement Unit (CTMU) for capacitive touch and time-of-flight measurements. Peripherals are supported by 19 general-purpose I/O pins and 16-channel 10-bit ADC capability.
Architecturally, the device pairs a 16-bit modified Harvard core with a wide range of digital and analog peripherals, with power management including multiple sleep modes and a switchable on-chip 3.3V regulator. The integrated USB OTG module eliminates the need for an external transceiver, reducing BOM cost and PCB area in Human Interface Device (HID), Mass Storage Class (MSC), CDC, and vendor-class USB designs.
Typical applications include USB human-interface devices such as keyboards/mice, USB-to-UART bridges, low-power sensor nodes with USB data logging, consumer electronics with USB charging/communication, industrial data acquisition with USB interface, and educational/development boards using the Explorer 16 platform. The wide operating voltage (2.0–3.6 V) and nanoWatt XLP technology also make it suitable for battery-powered products.
Design consideration: when laying out the PCB, place the 12 MHz crystal/oscillator traces short and symmetric, keep the USB D+/D- traces length-matched within 50 mils, and provide a solid ground plane under the SPDIP footprint for EMI suppression. The internal 3.3V regulator requires a bulk capacitor on VDD/VSS within a few millimeters of the device pins.

USB Human Interface Devices (HID)
The PIC24FJ64GB002-I/SP is purpose-built for USB HID devices such as keyboards, mice, game controllers, and custom input peripherals. Its integrated USB 2.0 Full-Speed OTG controller with internal transceiver eliminates the need for an external PHY, while the 16 MIPS PIC24F core runs Microchip's free USB HID stack comfortably. With 64 KB Flash and 8 KB RAM, it accommodates HID descriptors, scan buffers, and a CDC/bootloader. The 2.0–3.6 V supply plus nanoWatt XLP sleep (~20 nA) make it ideal for USB dongles drawing bus power. Designers pair this MCU with low-cost 12 MHz crystals and 27 Ω USB termination per Microchip's USB hardware design guide for EMI-compliant designs.

USB-to-UART Bridge / CDC Device
For USB-to-serial bridges, debug consoles, and CDC-class virtual COM ports, the PIC24FJ64GB002-I/SP delivers a compact solution with its integrated USB OTG, two UART channels, and nanoWatt XLP idle modes. The 16 MIPS core handles USB CDC stack plus UART bridging at up to 921,600 baud with minimal CPU load. Designers typically use the second UART for RS-485 level translation or GPIO expansion. The 28-pin SPDIP package is ideal for hand-soldered prototypes and educational platforms; 64 KB Flash accommodates the CDC class driver plus a custom protocol layer. Per Microchip's application notes, this MCU pairs well with MCP2200 for replacement of legacy RS-232 ports with USB on industrial machines.

USB Mass Storage Class (MSC) Devices
The PIC24FJ64GB002-I/SP supports USB Mass Storage Class (MSC) devices such as USB thumb drives, SD-card readers, and data loggers through its integrated USB OTG and 16 MIPS throughput. The 64 KB Flash fits the MSC class driver plus FAT32 file system library (Microchip's MLA), while the 8 KB RAM handles sector read/write buffers. The MCU interfaces to external NAND/NOR Flash or SD cards via SPI or 8-bit parallel port. Per Microchip's USB MSC reference designs, this MCU can achieve Full-Speed USB 2.0 throughput (~1 MB/s effective) when properly DMA-optimized, suitable for industrial data loggers, firmware update tools, and portable medical recorders.

Battery-Powered Sensor Nodes
The PIC24FJ64GB002-I/SP, built on Microchip's nanoWatt XLP technology, suits battery-powered sensor nodes that periodically wake to sample sensors and connect via USB for data retrieval. Sleep currents as low as ~20 nA (per datasheet) combined with the integrated USB OTG enable multi-year battery life on 2x AA cells when USB is used only for occasional data download or charging. The CTMU module supports capacitive touch sensors, and the 10-bit ADC handles analog sensor inputs. Designers can implement USB suspend/resume to further cut idle power. The 2.0–3.6 V VDD range is compatible with single-cell Li-ion via 3.3V LDO and 2x AA directly, making this MCU ideal for environmental monitors, asset trackers, and wearable health devices.

Industrial Data Acquisition with USB
For industrial data-acquisition front-ends and lab instrumentation, the PIC24FJ64GB002-I/SP provides a USB-tethered 16-bit MCU with 10-bit ADC, 3 comparators, CTMU, and 5 PWM outputs. The integrated USB OTG streams ADC samples to a host PC at up to 1 MSPS aggregate throughput using bulk transfers, sufficient for oscilloscope front-ends, multimeter data loggers, and process-control interfaces. The -40 °C to +85 °C industrial temperature rating and robust ESD performance on USB lines make it deployment-ready for factory floors. With 64 KB Flash, designers can embed calibration tables, digital filters (FIR/IIR), and USB command protocols without external memory.

Educational & Development Platforms
The PIC24FJ64GB002-I/SP's through-hole SPDIP-28 package is ideal for educational boards, breadboard-friendly prototypes, and Microchip's Explorer 16/32 development ecosystem. The 28-pin DIP form factor fits standard 0.300" sockets used in university labs, allowing students to swap microcontrollers without rework. Combined with MPLAB X IDE, XC16 compiler, and Microchip's Code Configurator (MCC), learners can quickly prototype USB device classes (HID, CDC, MSC) and peripheral drivers. The 64 KB Flash accommodates small RTOS kernels (FreeRTOS port available) and bootloader examples. The PIC24FJ64GB002 family is also featured in Microchip's training curriculum and academic program, making it a common reference design for embedded systems courses.

설계 노트
The PIC24FJ64GB002-I/SP supports a 2.0–3.6 V VDD range and includes an internal 3.3V voltage regulator. For noise-sensitive analog applications, Microchip recommends disabling the internal regulator (set DISVREG bit) and supplying the core directly from an external 3.3V LDO with 1% accuracy. Add a 10 µF bulk + 0.1 µF ceramic decoupling pair within 5 mm of VDD/VSS pins. The USB VBUS pin (pin 14) requires a 5 V-tolerant connection and a 100 nF decoupling capacitor to ground for VBUS sensing stability.
Route USB D+ (pin 15) and D- (pin 16) as a 90 Ω differential pair with length-matched traces (delta < 50 mils / 1.27 mm), per Microchip's USB hardware design guidelines. Keep the 27 Ω series termination resistors within 5 mm of the device pins. Place the 12 MHz crystal (with associated load capacitors) as close as possible to OSC1/OSC2 (pins 9/10), and surround the crystal with a ground guard ring to reduce EMI pickup. Maintain a continuous ground plane beneath the SPDIP-28 footprint for return-current integrity.
Common pitfalls when designing with the PIC24FJ64GB002-I/SP: (1) Forgetting to enable the internal PLL and the 48 MHz USB clock domain — USB Full-Speed will not enumerate without it. (2) Using long, unshielded USB cables without common-mode chokes — this risks USB compliance failures. (3) Not configuring the DISVREG pin correctly when using an external 3.3V supply, per Microchip's PIC24FJ64GB errata. (4) Driving MCLR low without a 10 kΩ pull-up, which prevents reliable reset. (5) Exceeding 5 V on any non-5V-tolerant pin — only VBUS (pin 14) is 5V tolerant. Always refer to the latest Microchip PIC24FJ64GB datasheet and errata sheet.
