PIC24FJ128DA110T-I/BG Présentation
Background Knowledge: A 16-bit microcontroller (MCU) is a programmable embedded processor that balances the throughput of 32-bit cores with the code density and low power consumption typical of 8-bit parts. The PIC24F family sits between Microchip's PIC16/PIC18 (8-bit) and dsPIC/PIC32 (16/32-bit) portfolios, offering DSP-class instructions, hardware multiply/divide, and linear memory addressing. In a typical system hierarchy, an MCU belongs to the embedded-computing class of semiconductors, sub-classified as microcontroller -> flash MCU -> 16-bit MCU -> low-power MCU -> graphics-enabled MCU. The integrated graphics controller and USB OTG put the PIC24FJ128DA110 into a niche for color LCD/graphics products.
Key features include 128 KB self-programmable Flash, 24 KB SRAM, hardware RTCC, 16-bit timers, a 10/12-bit ADC, and a graphics controller capable of directly driving displays up to 4.3-inch WQVGA (480x272) resolution. The peripheral set also includes UART, SPI, I2C, and a USB 2.0 OTG controller with integrated PHY.
Technical depth: The PIC24FJ128DA110 uses a Harvard architecture with separate program and data paths, a 16-bit data bus, and a 24-bit instruction word. The modified RISC core executes most instructions in one cycle, with hardware multiply and divide. The integrated graphics accelerator offloads draw operations from the CPU, allowing real-time GUI updates at low MHz.
Typical applications include embedded graphical user interfaces with color TFT/LCD panels, USB-enabled consumer products, low-cost HMI controllers, portable medical devices, and industrial control panels. It is suited for designs that need USB connectivity plus a display.
When designing with this part, plan PCB escape routing carefully for the 121-ball BGA; an external 12 MHz crystal is recommended when USB Full-Speed accuracy is required. A 4-layer PCB with stitched ground and a separate analog ground island improves ADC performance.

Applications typiques
PIC24FJ128DA110T-I/BG convient pour 6 applications: Color TFT/LCD HMI Controller, USB-Enabled Industrial Sensor Hub, Portable Medical Glucose/Infusion Reader, USB Barcode / QR Scanner Module, Smart Home Touch Panel Controller, Educational Microcontroller Trainer Board.
Color TFT/LCD HMI Controller
The PIC24FJ128DA110T-I/BG drives color TFT panels up to 4.3-inch WQVGA at 480x272 directly via its integrated graphics controller, eliminating external display ICs. Its 32 MHz 16-bit core and hardware line-draw accelerator deliver smooth 30+ FPS menu updates while leaving 24 KB RAM for double-buffered frame tiles. The 2.2-3.6 V supply range matches common single-cell Li-Ion HMI designs. USB OTG is available for touch data ingest or host-side firmware update on the production line.
Recommandé
USB-Enabled Industrial Sensor Hub
With integrated USB 2.0 Full-Speed OTG, the PIC24FJ128DA110T-I/BG acts as a USB device or host for industrial sensor data logging. The 10/12-bit ADC, 52 I/O pins, and multiple UART/SPI/I2C peripherals handle simultaneous multi-sensor sampling, while 128 KB Flash supports on-device calibration tables. Industrial -40C to +85C operation suits factory-floor enclosures, and 32 MHz core throughput meets typical 1 kHz control loop rates.
Recommandé
Portable Medical Glucose/Infusion Reader
The PIC24FJ128DA110T-I/BG's 32 MHz performance, low-power PIC24F core, and integrated graphics controller suit handheld medical readers with monochrome or color TFT displays. 24 KB RAM stores waveform or trend data while 128 KB Flash holds application firmware and ASCII LCD fonts. On-chip USB OTG supports wired data sync to PCs, and 2.2 V operation enables a single Li-Ion or 2xAA supply. Industrial temperature grade meets typical home-healthcare thermal envelopes.
Recommandé
USB Barcode / QR Scanner Module
The integrated USB Full-Speed OTG with on-chip PHY enables PIC24FJ128DA110T-I/BG to enumerate as a USB HID keyboard or vendor-class barcode scanner without external transceivers. The 52 I/O pins accept image-sensor data, while 128 KB Flash supports image-decoding libraries. 32 MHz core runs 1D/2D decode in <100 ms for typical barcodes, and the 121-ball TFBGA package allows compact scanner head designs with on-board graphics for diagnostics.
Recommandé
Smart Home Touch Panel Controller
The PIC24FJ128DA110T-I/BG's integrated graphics controller, 52 I/O, and USB OTG suit wall-mount smart-home touch panels driving 3.5 to 4.3-inch TFTs. The PIC24F core's Idle/Sleep modes reduce average current to support battery-backed wall mounts during brown-outs. 128 KB Flash stores GUI assets, Zigbee/BLE command tables, and device pairing state. Industrial temperature grade tolerates attics, garages, and outdoor-rated enclosures.
Recommandé
Educational Microcontroller Trainer Board
Educational labs use PIC24FJ128DA110T-I/BG as a modernized upgrade to PIC18F training kits, exposing 16-bit DSP-class instructions, USB OTG, and integrated graphics. The 121-ball TFBGA gives students hands-on BGA soldering practice, and 128 KB Flash / 24 KB RAM supports moderately complex projects like audio effects, USB MIDI, or mini-OS with multi-tasking. MPLAB X + XC16 free tier lowers entry cost for student labs and maker spaces.

Principaux différenciateurs
- Integrated graphics controller eliminates external display IC (vs PIC24FJ128GA110 family)
- USB 2.0 Full-Speed OTG with on-chip PHY (vs PIC24FJ128DA106 in TQFP-64)
- Higher pin count for full TFT data bus (vs PIC24FJ128DA106 in QFN-64 (PIC24FJ128DA106-I/MR))
Notes de conception
The 121-ball TFBGA at 0.8 mm pitch requires a 4-layer PCB minimum with a continuous ground plane under the BGA. Microstrip traces of 100 ohm differential impedance are needed for the USB D+/D- pair, and a 90-ohm differential is mandatory for USB Full-Speed compliance. Route the D+/D- pair first, length-matched within 150 mil. Decoupling: place 100 nF + 4.7 uF X5R on every VDD/VSS pair within 50 mil of the ball. Avoid running signal traces under the BGA, and stitch the package perimeter with a 4-via-per-side ground fence.
The PIC24FJ128DA110T-I/BG has a dedicated VCAP pin that requires a low-ESR 10 uF X5R capacitor plus a parallel 100 nF ceramic. This capacitor stabilizes the internal 1.8V core regulator. VUSB must be tied to 3.0-3.6V even when USB is unused, and a 1 uF + 100 nF decoupling pair is needed at VUSB. AVDD/AVSS should be filtered with a ferrite bead or 10 ohm resistor from VDD for best ADC noise performance. VBAT must be present (or tied to VDD) when the RTCC is used.
Common pitfalls: (1) forgetting MCLR pull-up; MCLR is active-low and must see a 10 kohm pull-up to VDD for normal operation. (2) Using the internal 8 MHz FRC for USB without enabling the PLL USB clock recovery - USB Full-Speed requires the 48 MHz USB clock derived from a precise primary oscillator. (3) Confusing the PIC24FJ128DA110 (with graphics) with PIC24FJ128GA110 (without graphics). (4) Driving LEDs directly from high-drive pins without series resistors. (5) Boot fail if DISPEN is held low during POR - graphics controller must be properly enabled in firmware before display access.
Use a star-ground topology for analog and digital grounds, joining at one point near the PIC24FJ128DA110T-I/BG. Keep the crystal oscillator traces (OSC1/OSC2) under 10 mm, surrounded by a ground guard ring, and place the load caps within 3 mm of the OSC pins. The secondary 32.768 kHz crystal for the RTCC must use the dedicated SOSCI/SOSCO pins with its own guard ring. JTAG/ICSP traces (PGECx/PGEDx) should be short (< 50 mm) and not share layers with high-speed USB or display data.
