PIC32MZ2025DAH176-I/2J - 200MHz 32-bit MCU with 2MB Flash | Microchip
MPN: PIC32MZ2025DAH176-I/2J ✓ AktifPIC32MZ2025DAH176-I/2J Ringkasan
A 32-bit microcontroller (MCU) is a single-chip computer whose CPU datapath, registers, and ALU are 32 bits wide, enabling high code density, large linear address spaces, and single-instruction throughput closer to that of a microprocessor than legacy 8- or 16-bit MCUs. Within the broader taxonomy, this part sits in the PIC32 family (32-bit MCU) under Microcontrollers (Integrated Circuits), and the PIC32MZ DA sub-family adds an integrated 2D graphics engine and stacked DDR2 DRAM controller so that the device can drive TFT LCD panels without an external graphics ASIC or memory.
Key features include 200 MHz CPU core, 2 MB Flash, 256 KB SRAM, integrated DDR2 controller and Graphics Processor, 12-bit ADC at 18 MSPS, HS USB 2.0 OTG, dual CAN, 10/100 Ethernet MAC, up to 45 analog inputs, and 120 GPIO. The 176-LQFP exposed pad gives an industrial-grade thermal path for sustained graphics workloads.
Architecturally, the PIC32MZ DA uses a 5-stage MIPS32 microAptiv pipeline with single-cycle MAC, hardware multiply/divide, and a dedicated GPU block that offloads primitives and fills so the CPU is free to run application logic and the RTOS.
Typical applications include HMI/GUI with TFT LCD, industrial control panels, automotive infotainment, smart appliances, and medical patient-interface displays. Choose this device when you need MCU simplicity with MPU-class graphics and multimedia throughput.
For design, place at least one 0.1 µF decoupling cap per VDD pin, keep DDR2 traces length-matched per the DDR2 layout guide, and use the exposed pad with a continuous ground copper pour to meet thermal targets.

Aplikasi Umum
PIC32MZ2025DAH176-I/2J cocok untuk 6 aplikasis: Industrial HMI with TFT LCD, Automotive Infotainment Sub-Display, Smart Appliance Control Panel, Medical Patient-Interface Display, Building Automation Touch Panels, Point-of-Sale Terminal with Color Display.
Industrial HMI with TFT LCD
The PIC32MZ2025DAH176-I/2J is purpose-built for industrial HMI panels driving TFT LCDs up to WVGA resolution. Its integrated 2D Graphics Processor offloads primitives, line draws, blits, and color fills from the CPU, allowing the MIPS32 microAptiv core to run the application logic and RTOS concurrently. The on-chip 32 MB stacked DDR2 provides ample frame buffer for multi-layer GUIs without an external SDRAM chip, simplifying PCB layout. With 120 GPIO, multiple SPI ports for display and touch controllers, and 12-bit 18 MSPS ADC for sensor input, this MCU replaces an MPU+external-GPU+external-SDRAM stack with a single chip. Compared to adding a discrete GPU ASIC, integrating the graphics block reduces BOM cost, PCB area, and firmware complexity while still delivering smooth 60 fps UI updates.

Automotive Infotainment Sub-Display
The PIC32MZ2025DAH176-I/2J suits automotive infotainment sub-displays such as HVAC panels, rear-seat entertainment touch screens, and instrument-cluster secondary zones. Its 200 MHz MIPS32 core runs real-time UI code while the integrated GPU renders gauge graphics, and HS USB 2.0 OTG provides connectivity to the head unit. Dual CAN interfaces integrate with vehicle CAN-FD networks, while 12-bit ADC inputs handle analog sensor signals. The -40C to +85C industrial temperature range covers cabin electronics. Compared to discrete MPU designs, integrating DDR2 controller and GPU cuts PCB area, BOM count, and EMI complexity. The 176-LQFP exposed pad simplifies thermal management in enclosed automotive enclosures.

Smart Appliance Control Panel
The PIC32MZ2025DAH176-I/2J powers the touch-screen control panel on premium smart appliances: washing machines, ovens, refrigerators, and robotic vacuums. The integrated graphics engine drives the user-facing TFT LCD at 60 fps with animated icons and progress indicators, while the MIPS32 core handles the appliance state machine, motor control loop, and Wi-Fi/BLE co-processor management via UART/SPI. The 120 GPIO count allows direct interface with capacitive touch controllers, segment drivers, and discrete indicators without external I/O expanders. Its 2 MB Flash supports full HMI firmware stacks including asset libraries, multilingual resources, and OTA update slots. Compared to discrete MCU plus external LCD controller, the integrated solution reduces BOM and accelerates time to market.

Medical Patient-Interface Display
The PIC32MZ2025DAH176-I/2J is appropriate for medical patient-interface displays such as infusion pump screens, patient monitor secondary displays, and diagnostic device control panels. Its 12-bit 18 MSPS ADC with up to 45 analog inputs provides precise digitization of sensor signals, while the integrated GPU renders smooth trend graphs and waveform visualizations. The MIPS32 core handles the safety-critical logic while the GPU refreshes the display in parallel. With HS USB and Ethernet, the device connects to hospital networks and bedside monitoring systems. The 2 MB Flash supports full IEC 62304-compliant firmware with bootloader and self-test routines. Compared to discrete MPU designs, the integrated graphics and DDR2 controller reduce PCB complexity and improve reliability.

Building Automation Touch Panels
The PIC32MZ2025DAH176-I/2J integrates the requirements of building automation touch panels: a graphical UI for floor plans, lighting scenes, and HVAC control; Ethernet connectivity for BACnet/Modbus-TCP networks; and CAN/RS-485 for fieldbus integration. The integrated GPU renders floor plans and lighting animations smoothly, while the MIPS32 core handles the building automation protocol stack and logic. With 2 MB Flash, the device stores full floor plans, multilingual strings, and OTA update slots. Compared to running a Linux MPU, the PIC32MZ2025DAH176-I/2J boots in under 100 ms, supports deterministic real-time response, and avoids the security maintenance burden of an OS.

Point-of-Sale Terminal with Color Display
The PIC32MZ2025DAH176-I/2J powers compact point-of-sale terminals that need a color TFT for menu display, signature capture, and QR code rendering. The integrated 2D GPU accelerates QR/barcode generation and screen transitions, while the MIPS32 core handles payment processing, encryption, and USB peripherals. HS USB 2.0 OTG connects to fiscal printers and external barcode scanners; Ethernet provides cloud payment gateway connectivity. With 256 KB SRAM, transaction buffers and cryptographic state fit comfortably. Compared to MPU-based POS designs, the integrated solution reduces BOM cost and enables fanless, compact enclosures with longer MTBF.

Diferensiator Kunci
- Highest on-chip stacked DRAM density in family (vsPIC32MZ2025DAG176-I/2J)
- Identical footprint with 2.5x SRAM upgrade available (vsPIC32MZ2064DAH176-I/2J)
- Tape-and-reel variant for high-volume SMT (vsPIC32MZ2025DAH176T-I/2J)
Catatan Desain
Estimated: the PIC32MZ2025DAH176-I/2J can draw 100-300 mA at 200 MHz with full DDR2 and GPU utilization. Place one 0.1 µF + one 4.7 µF ceramic capacitor within 5 mm of every VDD/VSS pin pair, and use a 4-layer PCB with a dedicated ground plane. The on-chip DDR2 LDO requires its own 1 µF bypass cap at the VDDR_CAP pin per Microchip's DDR2 routing guide.
DDR2 signals (DQ, DQS, CK, CKE, CS, RAS, CAS, WE, BA, A) require length-matched routing: data group ±25 mils, address/control ±50 mils, with proper series termination. Use fly-by topology if external DDR2 is fitted; the on-chip stacked DRAM routes internally and does not require external length matching. Maintain 50 ohm controlled impedance on all DDR2 nets.
Estimated: at full CPU+GPU load, the die dissipates ~0.8-1.2 W. The 176-LQFP exposed pad must be soldered to a copper pour of at least 1 square inch connected to ground. Without the exposed pad, junction temperature may exceed 125 C at industrial ambient. Use thermal vias under the pad to inner ground planes.
Do not skip configuring the FBS bits to enable the I/O port multiplexing needed for HS USB or Ethernet - leaving pins in default analog state will cause peripherals to fail. Also, the JTAG pins TCK/TMS/TDI/TDO must be left disconnected or pulled appropriately in production to avoid debug intrusion.
