MPN: PIC24FJ128DA110-I/PT ✓ Hoạt độngPIC24FJ128DA110-I/PT Tóm tắt
An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage; conversely, the PIC24FJ128DA110-I/PT sits within the broader taxonomy of MCU (microcontroller unit) -> embedded microcontroller -> 16-bit RISC MCU -> PIC24F family -> semiconductor. Understanding this hierarchy clarifies where this device competes: against other 16-bit low-power MCUs and against higher-end Cortex-M0+ parts for cost-sensitive graphical HMI designs.
Key features include a dedicated graphics controller with hardware-accelerated rendering for line, rectangle, and text drawing, USB On-The-Go (host + device role) with integrated PHY, a 10-bit ADC at 500 ksps, multiple UART/SPI/I2C peripherals, a Parallel Master Port (PMP) for external graphics memory or bus interfaces, and Microchip's eXtreme Low Power (XLP) technology with multiple sleep modes down to nanoWatt levels. The integrated Charge Time Measurement Unit (CTMU) supports capacitive touch sensing without external ICs.
Architecturally, the device pairs a 16-bit modified Harvard RISC core with a 24-bit instruction word and 16-bit data path, plus a dedicated graphics DMA engine that offloads pixel rendering from the CPU. The 32 MHz oscillator with PLL yields 16 MIPS throughput, more than sufficient for mid-resolution WQVGA UI animation. Internal voltage regulation supports 2.0V to 3.6V single-supply operation.
Typical applications include graphical user-interface panels, USB-connected human-interface devices, low-cost HMI touch screens with display up to 4.3-inch WQVGA, embedded data loggers with USB mass storage, and portable medical or industrial instruments requiring a monochrome or color TFT panel. The integrated graphics controller and CTMU allow a two-IC BOM (MCU + display) for many designs.
When designing with this part, evaluate whether your display resolution stays at or below 480x272; larger WVGA panels require the PIC24FJ256DA110 family or higher. Plan PCB layout for the USB OTG D+/D- 90-ohm differential pair and provide adequate decoupling (100 nF + bulk) on every VDD/VSS pin pair to keep the PLL clean.

Ứng dụng tiêu biểu
PIC24FJ128DA110-I/PT phù hợp cho 6 Áp dụngs: Graphical HMI with 4.3" WQVGA TFT, USB OTG Peripheral / Embedded Host, Industrial Control Panel with Touch, Portable Medical Instrument Display, Smart Home Control Panel, Embedded Data Logger with USB Mass Storage.
Graphical HMI with 4.3" WQVGA TFT
The PIC24FJ128DA110-I/PT's integrated graphics controller and 128 KB Flash make it a natural fit for driving 4.3-inch WQVGA (480x272) TFT panels. With hardware acceleration for line, rectangle, text, and bit-block transfers, the CPU is freed for application logic rather than pixel pumping. The CTMU enables capacitive touch scanning directly from the chip without a dedicated touch controller. Place the MCU close to the display data bus to minimize skew, and route PMP lines with matched impedance to keep the WQVGA frame rate above 30 fps without bus contention.

USB OTG Peripheral / Embedded Host
With integrated USB 2.0 On-The-Go (host + device) and on-chip PHY, the PIC24FJ128DA110-I/PT eliminates the need for an external PHY in USB-class designs. It supports HID, CDC, MSD, and vendor-class stacks from Microchip's MLA library. Application examples include USB mass-storage data loggers, USB keyboard/mouse embedded hosts, and CDC virtual COM ports. Route the D+/D- lines as a 90-ohm differential pair with no stubs, place a common-mode choke near the connector, and add a TVS protection array to meet ESD/EMI requirements.
Được đề xuất
Industrial Control Panel with Touch
The PIC24FJ128DA110-I/PT's CTMU peripheral enables capacitive touch sensing on a row/column matrix, supporting industrial control panels with up to 16-32 buttons without an external touch IC. The -40C to +85C industrial temperature range suits factory-floor environments. The device's nanoWatt XLP sleep modes keep idle power under 1 uA, supporting mains-powered and battery-backed installations. Combine with a 4.3-inch WQVGA panel for a full graphical industrial HMI.
Được đề xuất
Portable Medical Instrument Display
The PIC24FJ128DA110-I/PT is well-suited to portable medical instruments that require a small color TFT, USB data export, and capacitive touch for user input. The integrated graphics controller removes the BOM cost of a separate display driver, and the USB OTG port supports both charging and CDC/MSD data transfer to a host PC. Low-power XLP sleep modes extend battery life between measurement cycles. Designers should validate EMC per IEC 60601-1 and use a TVS-protected USB connector for patient-connected devices.
Được đề xuất
Smart Home Control Panel
For wall-mounted smart home control panels, the PIC24FJ128DA110-I/PT integrates a TFT driver, capacitive touch via CTMU, and USB for firmware update or commissioning. It pairs well with Wi-Fi co-processors over UART or SPI to offload radio duties. The 16 MIPS throughput drives 480x272 panels at 30+ fps while leaving CPU headroom for Zigbee or Matter stack bridges. The 100-pin TQFP gives ample GPIO for keypad backlight, status LEDs, and buzzer control on a single PCB.
Được đề xuất
Embedded Data Logger with USB Mass Storage
The PIC24FJ128DA110-I/PT's USB OTG device mode supports Mass Storage Class (MSC) on external SD cards or SPI Flash, enabling data loggers that appear as removable drives when plugged into a PC. The 128 KB Flash can host filesystem stacks plus the application, while 24 KB SRAM buffers write bursts. The CTMU and 10-bit ADC support sensor front-ends. Designers should wear-level the Flash via application-managed mapping and add a Schottky-protected USB VBUS path.

Ghi chú thiết kế
Route the USB OTG D+ and D- lines as a 90-ohm differential pair with no stubs, equal length matching within 150 mil, and a common-mode choke placed within 5 mm of the USB connector. Place the TVS protection array near the connector with a short ground return. Decouple every VDD/VSS pin pair with 100 nF ceramic plus a single bulk 4.7 uF or 10 uF tantalum. Keep the PLL crystal within 5 mm of the OSC1/OSC2 pins and guard the traces with a ground pour to suppress radiated emissions.
The integrated 1.8V core LDO derives from the 2.0V to 3.6V VDD rail; do not back-power VDD from the VUSB3V3 rail or vice versa. Brown-out reset thresholds are programmable; set BOR to the application minimum to maximize XLP nanoWatt savings. The device supports sleep currents under 1 uA in deep sleep with RTCC running, which is ideal for battery-backed applications. Validate that any attached display controller does not source current back through logic pins when the MCU is in reset.
Place the MCU adjacent to the TFT panel connector with PMP data lines (PMD0-PMD15), address lines (PMA0-PMA15), and strobes (PMRD/PMWR) of equal length. Group parallel data lines into a bus with ground traces between byte groups. The graphics controller can stall the PMP bus; reserve PMA15 and one PMCS line for self-refresh control to keep frame tearing off the screen. Keep CTMU touch traces short and shielded, and route them away from the USB differential pair.
