PIC32MZ2025DAR176T-I/2J 概要
A 32-bit microcontroller (MCU) is a single-chip processor that integrates CPU core, memory, and peripherals. The PIC32MZ DAR family sits at the high end of the PIC32 portfolio, blending MPU-class performance with MCU simplicity. Within the taxonomy, the device belongs to: microcontroller -> 32-bit MCU -> MIPS32 MCU -> PIC32MZ family -> PIC32MZ DAR sub-family. The DAR variant is purpose-built for human-machine-interface designs, distinguished from EF and EC sub-families by its graphics pipeline and DDR2 memory controller.
Key features include 2 MB of Flash (2M x 8), up to 640 KB of SRAM, on-chip support for external 32 MB or 128 MB DDR2 DRAM, and an integrated LCD controller. The 12-bit ADC achieves 18 MSPS, and the device offers up to 45 analog input channels. A hardware crypto engine, parallel master port, and 200 MHz core give the MCU enough throughput for advanced HMIs and connected IoT edge nodes.
Architecturally, the PIC32MZ DAR combines a MIPS32 microAptiv core with a dedicated graphics processor and DDR2 DRAM controller - a rare pairing in an MCU footprint. This dual-engine design lets a single chip drive WVGA-resolution displays while still handling application logic, eliminating the need for a separate graphics companion IC. The on-die Flash and SRAM provide deterministic code execution with zero external memory wait states for code stored in Flash.
Typical applications include industrial HMI panels, automotive infotainment, medical patient monitors, smart home control displays, and ruggedized portable terminals. The DDR2 controller allows large framebuffers without external SDRAM controllers, while the 12-bit 18 MSPS ADC supports simultaneous touchscreen and analog sensor monitoring.
When designing with this device, allocate PCB area for DDR2 routing with controlled-impedance traces and matched length matching, since the DDR2 interface is critical for graphics performance. The 176-LQFP exposed pad requires thermal vias for reliable operation above 100 mA core current.

Industrial HMI Touch Panels
The PIC32MZ2025DAR176T-I/2J drives WVGA-resolution resistive or capacitive touchscreens in factory automation panels with its integrated Graphics Controller, Graphics Processor, and DDR2 memory controller. The 200 MHz MIPS32 microAptiv core renders LVGL and emWin graphics smoothly while the 640 KB SRAM serves as framebuffer cache. The 12-bit 18 MSPS ADC reads the touch controller and analog sensor inputs simultaneously with no latency penalty. The 45 analog inputs handle multiple 4-20 mA sensor channels, encoder feedback, and supply voltage monitoring in one chip.

設計ノート
The 176-LQFP exposed thermal pad must be soldered to a PCB thermal land with at least 9 thermal vias (0.3 mm drill, 1 mm pitch) connecting to internal GND planes. Without thermal relief, the 200 MHz core will throttle under sustained graphics load. Estimated: at 1.8V core supply drawing 200 mA continuous, the die dissipates ~360 mW; junction temperature must stay below 85C with 1.5 oz copper pours and forced air for reliable industrial-temperature operation.
DDR2 DRAM routing requires matched-length traces within 25 mil tolerance on the clock, DQS, and data groups. Use 50 ohm controlled-impedance microstrip with 100 ohm differential for clock pairs. Place decoupling capacitors (0.1 uF and 4.7 uF) within 5 mm of each VDD pin. Per Microchip application notes for the PIC32MZ DAR family, the DDR2 reference voltage (DDR_VREF) must be generated from a dedicated low-noise LDO.
The PIC32MZ2025DAR176T-I/2J requires multiple supply rails: 1.8V core, 3.3V I/O, and a separate 1.8V DDR2 supply (or 2.5V depending on DDR2 chip). Use a sequencer or reset controller to enforce core-before-IO power-up to avoid latch-up. Estimated: inrush current at 200 MHz boot reaches 250 mA peak on the 1.8V rail; ensure the LDO can source 500 mA with adequate bulk capacitance.
Do not skip the 32.768 kHz low-frequency crystal on the SOSC pins if you intend to use the RTCC for timestamped event logging. Also, leave JTAG pins (TCK/TMS/TDO/TDI) accessible for production programming - routing them to test pads avoids expensive board rework. The 45 analog inputs share a 3.3V reference; do not exceed VDD+0.3V on any analog pin or the ADC will latch up.
コンプライアンス情報
RoHS and REACH compliant per Microchip product page. Industrial temperature grade (/2J suffix) is -40C to +85C, not AEC-Q100 automotive grade. For automotive infotainment, choose PIC32MZ1025DAR176-V/2J (AEC-Q100 grade 1, -40C to +125C).
