PIC24FJ128GB210-I/BG - 16-bit 32MHz 128KB Flash USB MCU | Microchip
MPN: PIC24FJ128GB210-I/BG ✓ فعالPIC24FJ128GB210-I/BG نمای کلی
A 16-bit microcontroller (MCU) is a microprocessor that processes data and addresses in 16-bit words, providing higher throughput and richer peripheral integration than 8-bit parts while retaining low power consumption. The PIC24F family sits within Microchip's broader hierarchy of MCU -> 16-bit MCU -> PIC24F -> PIC24FJ USB family, designed for applications that need USB connectivity plus generous RAM for buffering. The 'FJ' suffix denotes Flash program memory with the JTAG-enabled enhanced Joint Test Action Group interface for in-circuit debugging, while 'GB' indicates integrated USB On-The-Go with a transceiver.
Key features include USB 2.0 OTG with dual-role (Host or Device) capability, low-speed (1.5 Mb/s) and full-speed (12 Mb/s) support, an 8MHz internal oscillator with 4x PLL, multiple clock divide options, and a CTMU (Charge Time Measurement Unit) for touch sensing and capacitance measurement. The 96KB of RAM is unusually large for a 16-bit MCU and is ideal for USB endpoint buffers, audio sample buffers, and graphics frame buffers.
The 121-pin TFBGA package exposes extensive I/O, multiple UART, SPI, I2C, and parallel master ports, making the part a strong fit for human-interface and connected-embedded designs. Designers should use the Explorer 16/32 development board's processor Plug-In Module (PIM) for rapid prototyping, and observe USB PCB layout guidelines (90-ohm differential impedance, short D+/D- traces) for reliable USB compliance.
Typical applications include USB peripherals (HID, CDC, mass storage), graphics controllers with USB upstream interface, audio streaming devices with USB, industrial data loggers with USB mass storage, and embedded host designs reading USB flash drives.

کاربردهای معمول
PIC24FJ128GB210-I/BG مناسب است برای 6 کاربردs: USB HID Peripheral Devices, USB Mass Storage Reader (Embedded Host), USB CDC Virtual COM Port Devices, USB Audio Streaming Devices, Industrial Data Logger with USB Export, USB-Equipped Graphics HMI Panels.
USB HID Peripheral Devices
The PIC24FJ128GB210-I/BG is ideal for USB Human Interface Device (HID) peripherals such as keyboards, mice, game controllers, and custom input devices. The integrated USB 2.0 OTG controller with full-speed (12 Mb/s) support plus the 96KB of RAM comfortably hosts the Microchip USB stack and HID report buffers. The 32MHz CPU at 16 MIPS handles HID polling at the required 1ms interval with substantial headroom for debounce, macro processing, and LED animations. Designers can rely on the 121-pin TFBGA to expose enough I/O for matrix-scanned key switches, RGB lighting channels, and capacitive touch via the on-chip CTMU. The 128KB Flash accommodates HID report descriptors, device firmware upgrade (DFU) bootloaders, and application logic without compromise, while the industrial -40C to +85C temperature grade covers most consumer and embedded environments.

USB Mass Storage Reader (Embedded Host)
The PIC24FJ128GB210-I/BG excels as an embedded USB host that reads files from USB flash drives in industrial data loggers, instrumentation, and field-service tools. The USB OTG Host mode combined with the on-chip transceiver eliminates external PHY or USB power-switch ICs in many designs. The 96KB of RAM is large enough to buffer multi-sector reads from FAT-formatted USB sticks, while the 32MHz core supports real-time file enumeration and small-block writes without bottleneck. The CTMU and 12-bit ADC (typical of the family) let the same MCU digitize sensor data while serving as USB host, replacing a two-chip solution. The 121-pin TFBGA exposes ample I/O for SD-card backup paths, status LEDs, and keypad interfaces common in field-service devices.

USB CDC Virtual COM Port Devices
The PIC24FJ128GB210-I/BG is well suited for USB Communications Device Class (CDC) implementations that present as a virtual COM port to a host PC, enabling drop-in serial replacement of legacy RS-232 links. The USB Device mode and full-speed operation match the CDC ACM profile requirements, and the 96KB RAM supports line-coding buffers plus application-level ring buffers. Industrial sensor modules, motor controllers, and lab instruments frequently use CDC because it requires no host-side driver on modern OSes. The PIC24F core's deterministic interrupt latency simplifies time-stamping of CDC bulk-IN transfers, and the 128KB Flash holds the USB stack plus application protocols (Modbus, SCPI) without external storage.

USB Audio Streaming Devices
The PIC24FJ128GB210-I/BG's combination of USB Device support and 96KB of RAM enables USB audio class (UAC1) implementations such as USB speakers, USB microphones, and USB headsets. The 96KB RAM buffers USB isochronous packets at full-speed 1ms frame intervals while leaving headroom for sample-rate conversion and DSP effects. The 16-bit MCU's deterministic interrupt response maintains low USB packet-jitter, which is critical for glitch-free audio. Designers can use the I2S peripheral (typical of the family) to feed external DACs, and the CTMU for push-button volume control. The 121-pin TFBGA provides sufficient I/O for headphone jack sensing, LED status indicators, and I2C-controlled audio CODECs.

Industrial Data Logger with USB Export
The PIC24FJ128GB210-I/BG is a strong fit for industrial data loggers that record analog/digital process values and export logs via USB mass storage or CDC. The 12-bit ADC (typical of the PIC24F family) plus 96KB RAM enables on-device buffering of thousands of samples, while the USB OTG controller exports files to a USB stick when inserted - no PC required for retrieval. The industrial -40C to +85C operating range handles factory-floor environments, and the CTMU supports capacitive user-interface buttons on rugged enclosures. The 32MHz core runs averaging/peak detection algorithms in real time without starving USB transfers. The 121-TFBGA footprint exposes pins for RS-485 backup links, status LEDs, and tamper switches common in process instrumentation.

USB-Equipped Graphics HMI Panels
The PIC24FJ128GB210-I/BG supports small USB-connected HMI panels with simple on-device graphics and a USB upstream interface to a host controller. The Enhanced Parallel Master Port (EPMP) typical of the family drives small TFT displays from 128x128 to 320x240, while the USB Device port enumerates as CDC or vendor-class for command exchange with a host PLC or PC. The 96KB RAM holds graphics frame buffers for low-resolution monochrome or small color panels, and the 32MHz core refreshes displays without flicker. The 121-TFBGA exposes the bus pins for external SRAM/display plus the USB D+/D- lines. Industrial-grade temperature range suits control cabinet environments.

یادداشت‌های طراحی
Estimated: USB D+ and D- traces must be routed as a 90-ohm differential pair with matched length (delta under 150 mil), and the trace impedance must be controlled to 90 ohms to USB 2.0 spec. Place the 15 kohm pull-down on D- and 1.5 kohm pull-up on D+ close to the MCU pins. Keep the traces away from clock sources and switching regulators - USB is sensitive to common-mode noise above 50 mVpp. Add a ferrite bead on Vbus if the design is bus-powered, plus TVS diodes (e.g., USBLC6-2SC6) on D+/D- for ESD protection to IEC 61000-4-2 level 4.
Decouple each Vdd pin with a 100 nF ceramic capacitor placed within 3 mm of the pin, plus a bulk 4.7 uF or 10 uF tantalum/ceramic near the package. The PIC24FJ128GB210-I/BG has multiple Vdd/Vss pairs on the 121-TFBGA - every BGA row typically needs its own bypass cap. Use a star-ground topology from the USB connector shield to the MCU ground, and split analog/digital grounds only at the ADC area if mixed-signal performance is required.
Three common PIC24FJ USB mistakes: (1) forgetting the Vbus sense pin and the OTG ID pin configuration for host role, (2) omitting the 1.5 kohm pull-up on D+ until Vbus is stable (causes enumeration failures), and (3) using a too-small bulk capacitor on Vdd which collapses during USB cable insertion. Configure the USB interrupts with priority levels that preempt the main loop, and ensure the USB PLL lock flag is read before enabling USB transactions.
