PIC24FJ128DA110T-I/BG Обзор

The Microchip PIC24FJ128DA110T-I/BG is a 16-bit microcontroller from the PIC24F family, operating at up to 32 MHz and featuring 128 KB (43K x 24) of Flash program memory, 24 KB of RAM, and an integrated graphics controller with USB On-The-Go (OTG). It is housed in a 121-ball TFBGA (10x10 mm) package and provides 52 digital I/O pins for general-purpose use. The device combines low-power operation with an internal oscillator and is designed for cost-sensitive graphical interface applications.

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.

Where can I download the PIC24FJ128DA110T-I/BG datasheet PDF?
The official PIC24FJ128DA110 datasheet can be downloaded from Microchip's product portal at https://www.microchip.com/en-us/product/PIC24FJ128DA110. The same PDF covers all temperature grades and packages. Third-party mirrors also host the file; however, only the manufacturer-hosted copy is guaranteed to be the latest revision. The datasheet contains pinout, electrical characteristics, peripheral driver notes, and errata for the DA1 family.
Where can I find the PIC24FJ128DA110T-I/BG pinout and ball map?
The pinout for the 121-ball TFBGA is documented in the official PIC24FJ128DA110 datasheet Section 1.0 (Device Pinout) and Appendix B. Each ball is referenced by a TFBGA grid letter/digit coordinate (A1, A2, ..., N11). Always cross-check the package marking against the datasheet's ordering code table, because the I suffix denotes industrial temperature grade and the BG suffix denotes the 121-ball TFBGA.
What display resolutions does the PIC24FJ128DA110T-I/BG graphics controller support?
According to the PIC24FJ128DA110 datasheet, the integrated graphics controller can directly drive displays up to 4.3-inch WQVGA at 480x272 pixels.

The PIC24FJ128DA110 is the DA family member that integrates a graphics display controller, while the PIC24FJ128GA110 is the GA family without graphics acceleration. Both share the same 128 KB Flash, 24 KB RAM, USB OTG, and most peripherals. Choose the DA variant when driving a color TFT panel directly; choose the GA variant when no display is present and you want the same peripherals at lower cost.
What are the best drop-in alternatives to PIC24FJ128DA110T-I/BG in the same TFBGA-121 package?
Same-package drop-in alternatives within the PIC24FJ family are limited because the TFBGA-121 is a high-pin-count variant only used on the DA1 series. The PIC24FJ128DA110-I/BG (industrial, non-tape-and-reel suffix) shares the same die and footprint and is fully pin-compatible. Higher-density variants such as PIC24FJ256DA110 in TFBGA-121 are pin-compatible and provide 256 KB Flash. Always verify errata and revision ID before substitution.
Can the PIC24FJ256DA110 replace PIC24FJ128DA110T-I/BG directly on the same PCB?
Yes, the PIC24FJ256DA110 in the same 121-ball TFBGA (BG) package is a drop-in functional upgrade with doubled Flash (256 KB vs 128 KB) and the same peripherals. Voltage range, pinout, and temperature grade match, so no PCB rework is needed. Boot firmware should still verify the silicon revision ID via the Device ID register to ensure correct driver initialization across the two parts.

Choose the PIC24FJ128DA110T-I/BG when your design needs an integrated graphics controller and USB OTG in a single MCU for a color TFT HMI, with a small-footprint BGA and tape-and-reel packaging for high-volume SMT lines. Choose the PIC24FJ128DA110-I/BG (tray variant) when you want the same die on tray for prototyping or low-volume builds. Choose the PIC24FJ256DA110-I/BG when you anticipate needing 256 KB Flash for larger GUIs and your board design is locked to the TFBGA-121 footprint. Avoid TQFP-64 variants such as PIC24FJ128DA106 unless you cannot justify the BGA - they reduce available parallel display data lines and force external display bridges. For designs without USB OTG, the PIC24FJ128GA110 family saves cost by dropping the USB transceiver and graphics controller.

Заметки по проектированию

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.
