PIC24FJ128DA110T-I/PT Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and peripheral interfaces into one package. The PIC24F family sits between 8-bit PIC16/PIC18 devices and 32-bit PIC32 devices, offering 16-bit RISC performance, low-power sleep modes, and rich peripheral integration for cost-sensitive embedded designs. Within the PIC24F family, the 'DA' subgroup adds an on-chip graphics display controller targeting low-cost WQVGA TFT panels up to 4.3 inches and 480x272 resolution.
Key features include 16 MIPS performance, hardware PMP (Parallel Master Port) for graphics bus connection, integrated USB 2.0 full-speed OTG with on-chip transceiver, 4-wire resistive touch-screen controller, CTMU for capacitive touch, hardware crypto engine (AES/DES), Real-Time Clock and Calendar (RTCC) with calendar mode, and 16-channel 10-bit ADC. The 100-TQFP package exposes 84 I/O lines with flexible peripheral remapping, enabling direct bus connection to TFT panels without an external bridge ASIC.
The PIC24FJ128DA110 architecture is built around a modified Harvard RISC core with a 16-bit wide datapath, 24-bit instructions, and a 3-stage pipeline that delivers 8 MIPS at 32 MHz. The graphics controller includes a dedicated DMA-driven LCD interface supporting TFT panels up to WQVGA. Hardware AES-128 and DES blocks offload encryption tasks from the CPU, useful for secure USB applications and consumer devices needing basic content protection.
Typical applications include WQVGA TFT graphical user interfaces, USB-enabled medical devices, industrial HMI panels, point-of-sale terminals, USB peripherals (HID, CDC, MSD, Audio class), smart appliance control boards, and embedded graphical instruments. The integrated USB OTG with on-chip transceiver eliminates the need for an external PHY.
When designing with this device, allocate PCB area carefully because the 100-TQFP at 12x12 mm has 0.5 mm pitch and is a fine-pitch part - use 4 mil trace and space, reflow profile per J-STD-020, and follow Microchip's PCB layout guidelines for USB 2.0 high-speed analog pins. Decouple VDD/VUSB with 100 nF + 4.7 uF within 3 mm of the pins.

Notes de conception
The 100-TQFP package has 0.4 mm pitch, requiring 4 mil (0.1 mm) trace and space rules with reflow profile per J-STD-020. Place all decoupling capacitors (100 nF X7R + 4.7 uF bulk) within 3 mm of VDD/VSS pairs. For USB applications, route D+ and D- as a 90-ohm differential pair with length matching within 150 mil, and add external ESD protection (e.g., USBLC6-2SC6) directly at the connector. The VUSB pin requires a 1 uF + 100 nF decoupling network on its own ground reference.
Estimated: at 32 MHz CPU clock, full peripheral usage, and USB active, the PIC24FJ128DA110T-I/PT draws approximately 25-35 mA from a 3.3 V supply. For battery-powered designs, leverage the device's Deep Sleep mode (under 1 uA with RTCC active) for standby current reduction. Connect all VDD pins to a common supply and use a star-ground topology for the analog AVSS/AVDD pair if precision ADC readings are required.
Three common pitfalls: (1) Programming the device requires an ICSP-capable programmer (PICkit 3, PICkit 4, ICD 4, MPLAB SNAP) - in-circuit debugging uses the PGECx/PGEDx pins which must be accessible; (2) The 100-TQFP and 121-BGA packages of the DA110 share silicon but are NOT pin-compatible - do not assume BG can replace PT on the same PCB; (3) The graphics controller requires careful PMP pin assignment via PPS to avoid bus contention with peripherals.
For PMP-driven TFT panels, group PMDx, PMRD, PMWR, and PMA lines together with matched lengths to avoid display artifacts. Keep the analog AVSS pin tied to a quiet ground; isolate digital switching currents on VSS pins. Place the 32.768 kHz crystal within 5 mm of SOSCO/SOSCI with short traces and guard ring. For capacitive touch (CTMU), follow Microchip TB3069 layout guidelines - keep touch sensors trace-length matched and use grounded shielding on the PCB underside.
