PIC32MZ2025DAK176-I/2J Visão geral
What is a PIC32MZ DAK microcontroller? The PIC32MZ DAK series combines MPU-class graphics performance with the simplicity of an MCU for GUI-rich human-machine interface (HMI) applications. It belongs to the MIPS32 microAptiv family, which sits in the broader taxonomy of 32-bit embedded controllers (microcontroller -> 32-bit MCU -> MIPS architecture -> microAptiv core). This combination makes it suited for systems that need rich graphics, fast ADC, and connectivity in a single chip.
Key features include 200 MHz core clock, 2 MB Flash program memory, 640 KB SRAM, integrated DDR2 controller for external 32 MB or 128 MB DDR2, hardware Graphics Controller with dedicated Graphics Processor, 12-bit ADC at 18 MSPS with up to 45 analog input channels, HS USB 2.0, CAN 2.0, and a wide set of serial peripherals (UART, SPI, I2C). The 176-LQFP package with exposed pad improves thermal dissipation for full-speed operation.
The device uses a 5-stage MIPS32 microAptiv pipeline with DSP extensions, single-cycle hardware multiply/accumulate, and a tightly-coupled SRAM subsystem for deterministic performance. The integrated DDR2 controller removes the need for an external memory controller, simplifying board design for graphics-heavy GUI applications.
Typical applications include industrial HMI panels, automotive infotainment and cluster displays, medical patient monitors, point-of-sale terminals, smart home control panels, and any embedded GUI requiring hardware-accelerated graphics. The wide feature integration is particularly beneficial when system cost and PCB area must be minimized while still delivering smooth graphics rendering.
When designing with this device, allocate sufficient PCB copper for the exposed thermal pad and follow the manufacturer's DDR2 layout guidelines (matched-length traces, controlled impedance, decoupling close to the DDR2 pins) to achieve the rated 200 MHz operation and reliable DDR2 reads/writes.

Aplicações típicas
PIC32MZ2025DAK176-I/2J é adequado para 6 aplicaçãos: Industrial HMI Control Panels, Automotive Infotainment and Cluster Displays, Medical Patient Monitors, Point-of-Sale Terminals, Smart Home Control Panels, Industrial Test and Measurement Front Ends.
Industrial HMI Control Panels
The PIC32MZ2025DAK176-I/2J fits industrial HMI panels because its integrated Graphics Controller and dedicated GPU accelerate 2D rendering, freeing the 200 MHz MIPS32 microAptiv cores for application logic, PLC comms, and Modbus/TCP handling. Its 2 MB Flash stores multilingual UI assets, while the 12-bit 18 MSPS ADC reads touch and analog sensors in parallel without burdening the CPU. The wide 1.8 V core / 3.3 V I/O supply simplifies power-tree design against typical 24 V industrial backplanes.
Recomendado
Automotive Infotainment and Cluster Displays
The PIC32MZ2025DAK176-I/2J suits automotive infotainment and instrument clusters because the on-chip DDR2 controller drives WVGA resolution frame buffers at full 60 Hz from external 128 MB DDR2, while the hardware GPU offloads 2D compositing from the CPU. The integrated CAN 2.0 controller talks directly to vehicle networks, and HS USB handles media and diagnostic links. Designers benefit from the 176-LQFP with exposed pad, which simplifies thermal management in closed dashboards.
Recomendado
Medical Patient Monitors
The PIC32MZ2025DAK176-I/2J fits medical patient monitors where the 12-bit 18 MSPS ADC simultaneously samples multi-lead ECG, SpO2, and temperature channels, while the dedicated GPU drives a high-resolution waveform display. Its 640 KB SRAM holds double-buffered waveform data without external memory, and 2 MB Flash supports IEC 62304-validated firmware with revision history. The 200 MHz MIPS32 microAptiv core runs DSP-style FIR filters in single-cycle MAC instructions.
Recomendado
Point-of-Sale Terminals
The PIC32MZ2025DAK176-I/2J powers POS terminals by combining the integrated GPU for receipt preview and signature capture with HS USB for barcode scanners and printers. Its 2 MB Flash holds payment application code, multiple language fonts, and crypto libraries for PCI compliance. The DDR2 controller supports up to 128 MB external memory for transaction logs and product catalog caching at high throughput.
Recomendado
Smart Home Control Panels
The PIC32MZ2025DAK176-I/2J drives smart home control panels because its hardware Graphics Controller accelerates icon-based dashboards for lighting, HVAC, and security, while Wi-Fi companion modules attach over HS USB or SPI. The 12-bit ADC reads capacitive touch controllers, and CAN 2.0 supports HVAC bus communication. Low-power sleep modes with SRAM retention extend battery operation in wireless panels.
Recomendado
Industrial Test and Measurement Front Ends
The PIC32MZ2025DAK176-I/2J fits industrial test and measurement front ends where its 45-channel 12-bit 18 MSPS ADC simultaneously digitizes multi-sensor data while the 200 MHz core runs real-time DSP. The 2 MB Flash accommodates calibration tables and signal-processing libraries, and the DDR2 controller buffers waveform captures up to 128 MB. USB 2.0 Hi-Speed streams data to a host PC for visualization, while CAN reports aggregated results to PLC systems.

Principais diferenciais
- Highest Flash density in DAK tier (vs PIC32MZ1025DAK176-I/2J)
- Larger graphics tier than DAB/DAA siblings (vs PIC32MZ2025DAB176T-I/2J)
- Same 176-LQFP pinout as entire DAK family (vs PIC32MZ2025DAH176-I/2J)
Notas de projeto
The 176-LQFP package with exposed pad requires a continuous copper pour directly under the EP pin to provide thermal relief and ground reference. According to the Microchip PIC32MZ DAK layout guidelines, the exposed pad must be soldered to a copper area of at least 100 mm^2 for reliable 200 MHz operation, with multiple thermal vias connecting to an internal ground plane.
DDR2 traces to the external DRAM must be length-matched within +/-25 mils and routed with controlled 50 ohm single-ended impedance. The DDR2 clock pair requires 100 ohm differential routing. Place the DDR2 device within 25 mm of the MCU and isolate its power pins with a ferrite bead and dedicated decoupling (100 nF + 4.7 uF close to each supply pin).
Provide separate analog (AVDD) and digital (VDD) supply rails with ferrite-bead isolation, even though the PIC32MZ DAK internally ties them through ESD structures. Decouple each AVDD pin with 100 nF + 10 uF placed within 5 mm of the pin, and each VDD pin with 100 nF + 4.7 uF. The internal 1.8 V core LDO requires a bulk 10 uF on the VCAP pins.
Do not boot the PIC32MZ2025DAK176-I/2J with the DDR2 interface uninitialized - configure DDR2 controller timing registers in the device startup code before any graphics calls. Also avoid routing analog ADC traces near the DDR2 clock and DQS lines to prevent digital switching noise coupling into ADC samples at the 18 MSPS rate.
