PIC32MZ1025DAK176-I/2J 概要
What is a PIC32MZ Graphics MCU? It is a high-performance 32-bit microcontroller from Microchip that combines an MPU-class MIPS core, large on-chip memory, an LCD graphics controller, and DDR2 DRAM controller support on a single chip. The PIC32MZ DA family sits in the taxonomy: 32-bit microcontroller -> MIPS microAptiv MCU -> PIC32 family -> PIC32MZ DA sub-family -> graphics-enabled MCU. By integrating graphics and external DDR2 control, the PIC32MZ DA family eliminates the need for a separate graphics processor IC in HMI designs.
Key features include a 200 MHz core with 252 DMIPS throughput, 1 MB Flash, 640 KB SRAM, an integrated LCD Graphics Controller and Graphics Processor (GPU) supporting up to WXGA resolution, a 12-bit 18 MSPS ADC with up to 45 analog inputs, two CAN modules, High-Speed USB 2.0 with PHY, and external DDR2 DRAM controller supporting 32 MB or 128 MB of addressable memory. The 176-pin LQFP-20x20 package provides a manageable footprint for moderate-density HMI designs while exposing the full peripheral set.
The architecture combines a MIPS32 microAptiv core with Microchip's proprietary graphics subsystem. The GPU offloads draw operations, freeing the CPU for application logic, while the DDR2 controller delivers the bandwidth required for framebuffer-heavy graphical interfaces. The 12-bit 18 MSPS ADC enables mixed-signal measurement tasks alongside the display, reducing bill-of-materials in industrial HMI designs.
Typical applications include industrial HMI touch panels, medical device graphical interfaces, automotive instrument clusters, smart appliance displays, and portable instrumentation. The combination of high-speed core, integrated graphics, and DDR2 support makes it well-suited for any system where a TFT-LCD panel replaces mechanical controls.
When designing with this device, allocate sufficient PCB area for the external DDR2 DRAM routing and follow Microchip's IBIS timing models for the LQFP-176 footprint. Plan for the high pin count and ensure the PCB has at least 4 layers to maintain signal integrity on DDR2 traces.

Industrial HMI Touch Panels
The PIC32MZ1025DAK176-I/2J is purpose-built for industrial HMI panels with TFT-LCD displays. Its 200 MHz MIPS32 microAptiv core delivers the throughput needed for responsive touch UI loops, while the integrated Graphics Controller and Graphics Processor offload draw operations, freeing the CPU for communication tasks like Modbus, EtherCAT, or CAN. The 12-bit 18 MSPS ADC with up to 45 analog inputs enables front-panel analog sensing (temperature, voltage, current) without an external ADC. With 1 MB Flash for HMI assets and DDR2 controller supporting up to 128 MB, the device can drive WXGA panels with rich graphics while storing multilingual UI strings, fonts, and bitmaps.

Medical Device Graphical Interfaces
Medical devices such as patient monitors, infusion pumps, and diagnostic equipment require reliable graphical interfaces with deterministic response. The PIC32MZ1025DAK176-I/2J's 200 MHz core, integrated graphics subsystem, and 640 KB SRAM class memory support smooth waveform rendering and icon-heavy UI flows. The integrated 12-bit 18 MSPS ADC simplifies sensor front-end design for ECG, SpO2, or temperature channels by eliminating an external ADC. DDR2 controller support allows large waveform buffers and reference lookup tables. The industrial -40C to +85C temperature range (this -I variant) covers most clinical environments, while the V-temp PIC32MZ1025DAK176-V/2J upgrade path supports harsher sterilization equipment. Place this MCU at the heart of the display board with isolated power and IEC 60601-compliant analog front-end.
おすすめ
Automotive Instrument Clusters
Automotive instrument clusters increasingly use graphical displays replacing mechanical gauges. The PIC32MZ1025DAK176-I/2J drives the TFT panel through its integrated Graphics Controller while the CPU handles CAN bus traffic from ECUs. Two on-chip CAN modules enable direct connection to vehicle powertrain and body networks without an external transceiver-side MCU. While the -I variant operates to +85C, the V-temp PIC32MZ1025DAK176-V/2J upgrade in the same LQFP-176 footprint extends to +105C for under-dash installations. The DDR2 controller enables smooth needle/sweep animations and rich gauge graphics at 60 fps. The 1 MB Flash accommodates full instrument cluster bitmaps, while 640 KB SRAM class supports double-buffered framebuffers at common cluster resolutions like 800x480.
おすすめ
Smart Appliance Displays
Smart appliances such as connected ovens, refrigerators, washing machines, and HVAC controllers use TFT-LCD panels for user interaction. The PIC32MZ1025DAK176-I/2J provides the graphics performance for animated menus, recipe libraries, and Wi-Fi status displays while its 12-bit ADC monitors appliance sensors (temperature probes, motor current, water level). DDR2 controller support allows storing compressed recipe databases and firmware update staging buffers. The HS USB 2.0 with on-chip PHY enables direct firmware update via USB stick without an external PHY chip, reducing BOM cost. Two CAN modules allow integration into appliance bus networks or connection to compressor/inverter controllers. Industrial temperature grade is suitable for kitchen and laundry environments.
おすすめ
Portable Instrumentation
Portable test and measurement instruments - handheld oscilloscopes, cable certifiers, and field calibration tools - benefit from the PIC32MZ1025DAK176-I/2J's combination of high-performance graphics and fast analog. The 12-bit 18 MSPS ADC captures measurement signals while the Graphics Controller and GPU render waveforms, FFT plots, and touchscreen menus on the TFT display. DDR2 controller support allows deep waveform capture buffers (millions of samples) without resorting to slow SPI flash. The 200 MHz core sustains real-time DSP operations such as FFT, THD, or filter calculations. HS USB enables fast data export to PCs. Industrial temperature grade supports field use in varied climates. Place the LQFP-176 on a 4-layer PCB with dedicated analog and digital ground planes.
おすすめ
Building Automation Control Panels
Building automation systems - HVAC zone controllers, access control panels, energy management displays - require graphical interfaces that show real-time building status. The PIC32MZ1025DAK176-I/2J drives the touchscreen UI while the CAN bus interfaces communicate with HVAC actuators, lighting controllers, and access devices. The DDR2 controller supports large building floor plan bitmaps for visual system navigation. Two CAN modules allow redundant paths for safety-critical fire and security subsystems. The 12-bit ADC monitors local temperature, humidity, and occupancy sensors. Industrial temperature grade handles unconditioned equipment rooms and rooftop enclosures. Place the LQFP-176 on the main control board with isolated RS-485 transceivers for Modbus RTU integration with legacy building systems.

設計ノート
The 176-LQFP (20x20 mm) package has a 0.5 mm pitch and requires a 4-layer PCB minimum for reliable DDR2 signal integrity. Per Microchip's PIC32MZ Graphics family reference design, route DDR2 traces on inner layers with controlled impedance (50 ohm single-ended, 100 ohm differential for clocks), maintain matched lengths within the DDR2 timing budget, and isolate analog and digital ground planes joined only at the exposed thermal pad. Place decoupling capacitors as close as possible to each VDD pin pair.
The PIC32MZ1025DAK176-I/2J operates from a 1.8 V core supply; however, the I/O and DDR2 I/O typically require a 3.3 V rail. Plan for a multi-rail power tree with low-noise LDO for the 1.8 V core and a switching regulator or LDO for the 3.3 V rail. Estimated: at 200 MHz full operation, the core current draw is approximately 70-90 mA; I/O and DDR2 controller add another 50-80 mA. Place a bulk capacitor bank of at least 47 uF near the IC and 0.1 uF + 10 uF ceramic pairs at each supply pin.
Do not omit the MCLR pull-up resistor on pin 7 - the device will not start reliably without it. The DDR2 memory controller requires careful initialization sequencing in firmware; consult the PIC32MZ Graphics family datasheet DDR2 initialization section before bringing the controller out of reset. Also ensure the exposed thermal pad is soldered to the PCB ground plane with sufficient vias for heat dissipation - the device can dissipate 1-2 W under full graphics load.
Route the DDR2 clock (DDR2_CLK_P/N) first with matched length and differential impedance, then match the address/command traces to within the DDR2 timing skew budget (typically +/- 25 ps). Keep the 12-bit ADC analog inputs (AN0-AN6) routed away from the DDR2 switching signals to prevent coupling noise into the ADC. The TFT-LCD data lines (if used) should be length-matched within their respective bus groups.
