PIC32MZ2025DAK176-V/2J Overview
A 32-bit microcontroller (MCU) is a single-chip processor with on-chip Flash program memory, SRAM data memory, and a rich set of digital and analog peripherals. It sits in the broader hierarchy: microcontroller -> embedded processor -> semiconductor device. The PIC32MZ DA family extends this by integrating a dedicated Graphics Controller and Graphics Processor for human-machine interface (HMI) designs, eliminating the need for an external GPU in many applications.
Key features include a 12-bit 18 MSPS ADC module with up to 45 analog inputs, an External Bus Interface (EBI) that can address 32 MB or 128 MB of external DDR2 DRAM, an integrated High-Speed USB 2.0 PHY, a CAN module, and 120 general-purpose I/O pins. The device operates from 1.7 V to 1.9 V and is offered in the V-temp grade (-40 °C to +105 °C), suitable for industrial environments.
Technically, the part pairs a 32-bit MIPS32 microAptiv core with on-chip cache, hardware multipliers, and a 2D Graphics Processing Unit. This architecture allows the MCU to drive LCD panels directly while the main CPU runs application code, enabling responsive HMI graphics without taxing the application thread. Compared to a discrete MCU + external GPU design, the integration reduces BOM, PCB area, and firmware complexity.
Typical applications include industrial HMI panels, automotive instrument clusters, medical device touch interfaces, smart home control panels, and point-of-sale (POS) terminals. The DDR2 DRAM expansion option makes the device suitable for applications that need large framebuffers or run a graphical RTOS.
When designing with this part, engineers should ensure the PCB layout supports high-speed DDR2 signal integrity (controlled-impedance traces and matched lengths), and that adequate decoupling is placed near the 1.8 V core supply pins. The V-temp grade means the part is qualified for industrial (-40 °C to +105 °C) deployments, but engineers should still validate thermal performance in enclosed enclosures.

Typical Applications
PIC32MZ2025DAK176-V/2J is suitable for 6 applications: Industrial HMI Control Panels, Automotive Instrument Clusters, Medical Device Touch Interfaces, Smart Home Control Panels, Point-of-Sale (POS) Terminals, Building Automation Touch Interfaces.
Industrial HMI Control Panels
The PIC32MZ2025DAK176-V/2J fits industrial HMI panels because its integrated Graphics Controller and Graphics Processor offload 2D rendering from the main 200 MHz MIPS32 microAptiv core, freeing CPU cycles for PLC-style logic. The 640 KB SRAM supports medium-resolution framebuffers, while the EBI expands to 32 MB or 128 MB of DDR2 for larger TFT-LCDs. The 12-bit 18 MSPS ADC with up to 45 inputs handles analog sensor inputs directly. The V-temp grade (-40 °C to +105 °C) is critical for factory-floor enclosures.
Recommended
Automotive Instrument Clusters
The PIC32MZ2025DAK176-V/2J targets automotive cluster designs because the integrated Graphics Processor drives the speedometer/tachometer/infotainment display without external GPU cost. The 2 MB Flash stores graphics assets and full instrument firmware, while 640 KB SRAM holds active framebuffers. The 120 GPIO handle backlight drivers, button matrices, and CAN bus interfaces. Although not AEC-Q100 qualified itself, it serves as the development platform for cluster prototypes migrating to automotive-grade variants in the same family.
Recommended
Medical Device Touch Interfaces
The PIC32MZ2025DAK176-V/2J is well-suited for medical touch interfaces because the integrated Graphics Controller and Graphics Processor deliver smooth menu transitions on patient monitors and diagnostic equipment displays. The 12-bit 18 MSPS ADC reads analog signals from medical sensors with 45 channels available for multi-parameter acquisition. The 1.7 V to 1.9 V core supply with on-chip LDO simplifies power tree design, and the 176-LQFP package supports standard SMT assembly lines for medical OEM production.
Recommended
Smart Home Control Panels
The PIC32MZ2025DAK176-V/2J drives smart-home wall-mounted control panels because the integrated Graphics Processor renders touch-based home automation UIs without an external GPU. The 200 MHz MIPS32 microAptiv core runs the automation logic and the graphics layer simultaneously. The High-Speed USB 2.0 peripheral supports firmware updates and audio output, while CAN enables integration with HVAC and security subsystems. The 176-LQFP package fits compact wall-mount enclosures.
Recommended
Point-of-Sale (POS) Terminals
The PIC32MZ2025DAK176-V/2J suits POS terminal designs because the integrated Graphics Controller and Graphics Processor render transaction UIs, receipt previews, and signature capture screens on integrated LCDs. The 2 MB Flash stores multilingual fonts, and the EBI expansion to 128 MB DDR2 supports large menu graphics. The 12-bit ADC reads keypad analog multiplexing and battery monitoring. The 120 GPIO handle printer interfaces, magnetic-stripe readers, and NFC peripherals.
Recommended
Building Automation Touch Interfaces
The PIC32MZ2025DAK176-V/2J supports building automation touch interfaces because the integrated Graphics Processor renders floor-plan visualizations and lighting/HVAC controls on wall-mounted panels. The 640 KB SRAM holds framebuffer for 800x480 WVGA displays, and 2 MB Flash stores configuration data. The CAN peripheral integrates with industrial building networks. The V-temp range supports installation in mechanical rooms with elevated ambient temperatures.

Key Differentiators
- Largest on-chip memory in the PIC32MZ Graphics DA family (vs PIC32MZ1025DAS176-V/2J)
- Wider operating temperature range (V-temp grade) (vs PIC32MZ2025DAK176-I/2J)
- Integrated Graphics Processor eliminates external GPU cost (vs PIC32MX795F512L-80I/BG)
Design Notes
Estimated: When using the External Bus Interface (EBI) with external DDR2 DRAM, controlled-impedance traces (typically 50 ohm single-ended, 100 ohm differential) and matched trace lengths within the DDR2 clock group are required. Place 0.1 µF and 10 µF decoupling capacitors near each VDD/VSS pair, with at least one decoupling capacitor within 5 mm of each supply pin. DDR2 reference voltage (VREF) requires 1 µF + 0.1 µF decoupling at the VREF pin.
Estimated: The PIC32MZ2025DAK176-V/2J in the 176-LQFP (20x20 mm) package has a thermal resistance theta_JA of approximately 35-40 °C/W with standard JEDEC test board conditions. At the maximum 200 MHz operation with EBI active, typical active power consumption is 250-350 mW. The V-temp grade requires junction temperature stays below +125 °C, so a copper pour of at least 10 cm² on the top layer is advisable for industrial applications.
The PIC32MZ2025DAK176-V/2J operates at 1.7 V to 1.9 V core voltage; using a 3.3 V supply without proper LDO regulation will damage the part. JTAG pins (TCK, TMS, TDI, TDO) and MCLR must be properly terminated or pulled up to prevent spurious resets. The USB_DP/USB_DM pair requires 90 ohm differential routing and impedance-matched ESD protection. Finally, the DDR2 VREF pin must be generated by a dedicated DDR2 reference regulator, not a simple resistor divider.
Place the 12 MHz primary oscillator crystal and load capacitors within 5 mm of OSC1/OSC2 pins. Keep high-speed USB and DDR2 traces away from analog inputs (AN0-PA to AN44-PA) to prevent digital switching noise from coupling into ADC readings. Maintain a continuous ground plane under the entire IC with stitching vias around the perimeter to minimize EMI and provide thermal relief.
Compliance Information
