PIC24FJ128DA110-I/BG - 16-Bit 32MHz MCU 128KB Flash USB Graphics | Microchip
MPN： PIC24FJ128DA110-I/BG ✓ 啟用中PIC24FJ128DA110-I/BG 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and peripherals such as timers, communication interfaces, and analog blocks. The PIC24F family uses a 16-bit modified Harvard architecture with a wide 24-bit instruction word optimized for C compiler efficiency. Microcontrollers sit in the embedded computing hierarchy above 8-bit MCUs but below 32-bit MCUs, balancing code density, peripheral integration, and power consumption for cost-sensitive embedded products.
The PIC24FJ128DA110-I/BG integrates a graphics controller that can drive displays up to 4.3" WQVGA (480x272), supporting resistive touch sensing via the integrated A/D converter. It also includes USB OTG with on-chip transceiver, eliminating the need for an external PHY. The 32MHz core delivers up to 16 MIPS, while the nanoWatt XLP power-down modes allow deep sleep currents below 1 uA, making it suitable for battery-powered graphical products.
This device is part of the PIC24FJ-DA family, which adds graphics acceleration hardware (line draw, rectangle fill, text rendering) directly in silicon. The combination of 128KB self-programmable Flash, 24KB SRAM, and 52 digital I/O pins provides ample headroom for graphical UI stacks while leaving room for application logic. Real-time peripherals include 5 timer/counters, Input Capture, Output Compare, I2C, SPI, UART, and a 10-bit 1.1 Msps A/D converter with up to 32 input channels.
Typical applications include wearable fitness displays, portable medical monitors, industrial HMI panels, smart thermostats, USB-connected graphical instruments, and low-cost graphical toys. The integrated USB OTG also enables the part to act as both USB device and limited host, useful for accessories that need to read USB flash drives or HID peripherals. The TFBGA-121 package supports compact board layouts, though it requires 4-layer PCB with microvia technology for reliable assembly.
When designing with this part, allocate the 4-layer PCB budget for TFBGA fanout, and place the 32 kHz secondary oscillator crystal close to the SOSCO/SOSCI pins to avoid start-up drift. The graphics controller is RAM-framebuffer based, so allocate sufficient external SRAM when driving larger panels.

設計說明
The 121-ball TFBGA package requires a 4-layer PCB with microvia (laser-drilled) technology for reliable fanout routing. Use a 0.5 mm pitch escape pattern with via-in-pad or dog-bone fanout to inner signal layers. The exposed die paddle (if present) must be soldered to a ground plane for thermal dissipation; per Microchip PCB guidelines, allocate at least 50 mm squared of unbroken copper beneath the BGA.
Decouple VDD/VSS pairs with 100 nF ceramic capacitors placed within 3 mm of each supply ball. Add a bulk 10 uF tantalum or ceramic capacitor near the MCU for transient response during USB OTG bus events. The 32 kHz secondary crystal (SOSCI/SOSCO) pins should each have 15-33 pF load capacitors to ground; per Microchip datasheet section on oscillator design, mismatched capacitance causes start-up failures in production.
Route USB D+ and D- as a 90 ohm differential pair from the MCU balls to the USB connector. Match lengths within 150 mil and keep the pair away from switching signals and clock oscillators. The on-chip USB transceiver requires the VUSB ball to be decoupled with a 0.01 uF capacitor to ground within 5 mm; failure to do this can cause USB enumeration failures.
When migrating firmware between the 64-pin (BG) and 100-pin (PT) variants of the PIC24FJ128DA110, ensure unused analog input pins are configured as digital outputs or analog-disabled. Per Microchip errata documents, leaving analog pins floating can inject noise into adjacent A/D channels and cause spurious wake-ups from sleep mode. Always check the latest device errata sheet before finalizing PCB layout.
