PIC24FJ128DA210-I/PT 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals (timers, ADC, communication controllers, I/O). The PIC24F family is Microchip's 16-bit extension of the 8-bit PIC architecture, sharing the same development environment (MPLAB X IDE, XC16 compiler) but adding DSP instructions, larger address space, and higher throughput. Within Microchip's portfolio, the PIC24FJ128DA210 belongs to the graphics-enabled "DA" sub-family, sitting between general-purpose PIC24FJ128GA and high-performance PIC24EP series.
Key features include 128KB (43K x 24 instruction words) Flash, 24KB RAM, an on-chip 96KB frame buffer for graphics, 3.3V operation, and a peripheral set that includes USB OTG, parallel master port, I2C, SPI, UART, 16-bit timers, and a 10-bit ADC. The integrated graphics controller supports TFT panels with up to 4.3" WQVGA resolution, eliminating the need for an external display controller in many HMI designs.
The PIC24FJ128DA210-I/PT integrates the core and graphics acceleration into a single die, reducing BOM cost and PCB area in graphical product designs. Compared to using a discrete MCU plus external LCD controller, the integrated approach reduces component count and simplifies firmware development by providing hardware-accelerated drawing primitives.
Typical applications include low-cost graphical HMI panels, home appliance user interfaces, medical device displays, industrial control screens, point-of-sale terminals, and USB-connected embedded devices. The part is well suited to any application needing rich on-screen graphics without the cost of a higher-end ARM-based MCU.
When designing with this part, allocate PCB area for the 100-pin TQFP package (12x12 mm) and provide proper decoupling near the analog and digital supply pins. The USB OTG interface requires 0.1uF decoupling on VUSB3V3 and a 27-ohm series resistor on D+/D- lines per USB specification.

典型应用
PIC24FJ128DA210-I/PT 适用于 7 应用s: Home Appliance User Interfaces, Industrial Control Panels, Medical Device Displays, Point-of-Sale (POS) Terminals, USB-Connected Embedded Devices, Smart Home Control Panels, Automotive Infotainment Aux Displays.
Home Appliance User Interfaces
The PIC24FJ128DA210-I/PT's integrated graphics controller drives up to 4.3-inch WQVGA TFT panels, eliminating the need for an external LCD controller in dishwasher, washing machine, and oven HMIs. With 128KB Flash, 24KB RAM, and 16 MIPS throughput, it provides headroom for bitmapped icons, multi-language fonts, and animated menus. The 2.0V-3.6V supply range accommodates 3.3V rails and 2x AA battery backup, while the -40C to +85C industrial temperature rating covers inside-cabinet appliance environments.
推荐
Industrial Control Panels
The PIC24FJ128DA210-I/PT is suited to industrial HMI panels that need a graphical status display without the cost of an ARM Cortex MCU. Its Parallel Master Port (PMP) interfaces directly to external SRAM, NOR Flash, or FPGA registers, while USB OTG enables field updates via USB stick. The integrated graphics controller reduces CPU load, leaving bandwidth for PLC communication (UART, SPI, I2C) and real-time sensor sampling via the 10-bit ADC at industrial temperatures.
推荐
Medical Device Displays
Patient monitors, infusion pumps, and diagnostic handhelds benefit from the PIC24FJ128DA210-I/PT's combination of low-power 16-bit core, integrated graphics, and 10-bit ADC for sensor front-ends. The 32MHz/16 MIPS performance runs display refresh and signal-processing algorithms simultaneously without an external GPU. The industrial temperature range (-40C to +85C) supports clinical and field environments, and the 100-pin TQFP package is well-suited to mid-volume medical designs.
推荐
Point-of-Sale (POS) Terminals
POS terminals require a graphical user interface, USB connectivity for peripherals (barcode scanners, receipt printers, customer displays), and reliable long-term operation. The PIC24FJ128DA210-I/PT's USB OTG supports both device (PC host) and host (USB peripherals) modes, while the integrated graphics controller drives the merchant-facing color TFT without external components. 128KB Flash fits typical POS firmware with firmware-over-USB field updates enabled by the on-chip USB bootloader.
推荐
USB-Connected Embedded Devices
The PIC24FJ128DA210-I/PT integrates USB On-The-Go with both Host and Device role support, including Session Request Protocol (SRP) and Host Negotiation Protocol (HNP). This makes the part well suited to data loggers, USB sensors, and tethered industrial peripherals that communicate with a host PC or another USB device. The 24KB RAM buffer handles USB endpoint packets without external memory.
推荐
Smart Home Control Panels
Wall-mounted smart-home controllers, multi-zone thermostats, and security keypads often need a graphical display and USB connectivity for setup. The PIC24FJ128DA210-I/PT's TFT graphics controller renders room maps, weather widgets, and animated icons directly, while USB OTG enables wired commissioning via phone or laptop. The 2.0V-3.6V supply supports direct battery backup during AC mains loss, and the 100-pin TQFP package leaves room for additional peripherals via UART/SPI/I2C.
推荐
Automotive Infotainment Aux Displays
Secondary automotive displays (rear-seat entertainment, HVAC sub-displays, motorcycle dashboards) need compact graphical HMIs at moderate cost. The PIC24FJ128DA210-I/PT provides integrated graphics up to 4.3-inch WQVGA and 16 MIPS performance for graphics rendering, though for under-hood or AEC-Q100-qualified automotive applications designers should select the PIC24FJ-DA automotive-grade variants. The 100-pin TQFP package supports mid-volume automotive production.

设计说明
The PIC24FJ128DA210-I/PT requires a 2.0V-3.6V regulated supply on each VDD/VDDcore pin pair, with a 0.1uF ceramic decoupling capacitor placed within 3mm of each pin pair per Microchip datasheet recommendations. For USB OTG operation, a separate 3.3V rail (VUSB3V3) is required even if the core runs at 2.5V, and a 4.7uF bulk capacitor plus 0.1uF decoupling is recommended on the USB supply pin to handle inrush during cable attachment events.
The 100-pin TQFP package (12x12 mm, 0.5 mm pitch) requires careful PCB layout: use 0.25mm-wide traces with 0.20mm spaces exiting the pads, fan out to inner layers, and provide a continuous ground plane on layer 2 for reference. Maintain at least 0.5mm clearance between TFT data lines and the USB D+/D- differential pair to avoid coupling noise into the USB signal. Match the USB D+/D- trace length to within 2mm per USB 2.0 full-speed specification.
Common pitfalls with the PIC24FJ128DA210-I/PT include: (1) forgetting to configure the JTAG/ICSP pins as GPIO by clearing the JTAGEN fuse, which leaves those pins unavailable for general use; (2) failing to add a 27-ohm series resistor on USB D+/D- lines per USB spec; (3) omitting the 32.768 kHz secondary oscillator load capacitors, which prevents the RTCC from locking. The Microchip datasheet section 2 (pinout) and section 30 (USB) provide the authoritative reference designs.
When routing the parallel TFT data bus, keep all TFT_D[15:0] traces matched in length to within 5mm to avoid skew on the parallel master port. Place a ground guard trace between the TFT bus and adjacent signal lines to reduce crosstalk. The PMP interface runs at up to 16MHz, so keep trace lengths under 50mm where possible and avoid vias on the TFT data bus.
合规信息
RoHS and REACH compliant per Microchip product page. The -I/PT suffix denotes industrial temperature grade (-40C to +85C); the part is not AEC-Q100 qualified - select automotive-qualified PIC24F variants for AEC-Q100 applications.
