PIC24FJ128DA110T-I/BG - 16-bit 32MHz MCU, 128KB Flash, 121-TFBGA | Microchip
MPN: PIC24FJ128DA110T-I/BG ✓ AktifPIC24FJ128DA110T-I/BG Ringkasan
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.

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.

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.

Diferensiator Kunci
- Integrated graphics controller eliminates external display IC (vsPIC24FJ128GA110 family)
- USB 2.0 Full-Speed OTG with on-chip PHY (vsPIC24FJ128DA106 in TQFP-64)
- Higher pin count for full TFT data bus (vsPIC24FJ128DA106 in QFN-64 (PIC24FJ128DA106-I/MR))
Catatan Desain
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.
