MPN： PIC32MZ2025DAK169-V/HF ✓ 啟用中PIC32MZ2025DAK169-V/HF 概覽
A 32-bit microcontroller (MCU) is a single-chip processor that integrates a high-throughput CPU, on-chip memory (Flash for code, SRAM for data), and a broad set of peripherals (ADC, timers, communication controllers, GPIO). The PIC32MZ family extends the classic PIC microcontroller lineage with a MIPS32 microAptiv core, instruction-cache architecture, and DMA, positioning these MCUs above 8/16-bit MCUs but below full microprocessors in complexity. The PIC32MZ Graphics (DAK/DAL/DAR/DAS) family specifically adds an integrated graphics controller, a graphics processor, and an external DDR2 DRAM interface to enable LCD-TFT panels up to WVGA without external graphics silicon.
Key features of the PIC32MZ2025DAK169-V/HF include a 12-bit 18 MSPS ADC with up to 45 analog inputs, two CAN modules, HS USB with on-chip transceiver, an integrated graphics controller with hardware-accelerated rendering, and support for up to 32 MB on-chip or 128 MB externally addressable DDR2 DRAM. The 169-LFBGA package exposes the wide data path needed to drive parallel RGB displays and connect to external DDR2 memory.
Architecturally, the device pairs a single-issue MIPS32 microAptiv core with tightly-coupled instruction cache and a dedicated graphics DMA path, allowing the CPU to remain responsive while the GPU streams frame-buffer data to the LCD. The 200 MHz core delivers 330 DMIPS and 3.46 CoreMark/MHz-class efficiency for the segment.
Typical applications span industrial HMI panels with TFT LCDs, medical patient-monitoring displays, point-of-sale terminals, automotive-infotainment prototypes, and home-automation touch-screen controllers. Engineers select the DAK169 variant when the design needs a 169-ball BGA footprint for compact board layout and high-pin-count LCD interface routing.
Designers should review the package thermal resistance, the DDR2 PCB layout rules, and the Graphics Controller middleware licensing before committing. The PIC32MZ Graphics Family datasheet (DS60001565) covers register definitions, the DDR2 controller timing, and the recommended LCD-TFT interface.
This page synthesizes distributor pricing from DigiKey/Mouser/LCSC, the Microchip product family listing, and drop-in same-family alternatives sourced from the verified cross-reference data to help engineers compare, source, and qualify the part more efficiently than reading the 169-ball pinout alone.

典型應用
PIC32MZ2025DAK169-V/HF 適用於 6 應用s: Industrial HMI with TFT LCD, Medical Patient Monitoring Display, Point-of-Sale Terminal, Home Automation Touchscreen Controller, Automotive Infotainment Prototype, Industrial Control Panel with Connectivity.
Industrial HMI with TFT LCD
The PIC32MZ2025DAK169-V/HF fits industrial HMI panels because its integrated graphics controller, integrated graphics processor, and 200 MHz MIPS32 microAptiv core deliver smooth 2D rendering for WVGA panels up to 800x480 without external GPU silicon. The 640 KB SRAM plus externally addressable DDR2 (up to 128 MB) provides ample frame buffer, while the 2 MB Flash stores asset data and application code.

Medical Patient Monitoring Display
The PIC32MZ2025DAK169-V/HF suits medical patient monitoring displays because the V-temp range (-40 to +105 C) covers continuous-operation equipment enclosures, while 12-bit 18 MSPS ADC with up to 45 analog inputs digitizes multiple sensor channels simultaneously for ECG, SpO2, and temperature inputs. The integrated graphics controller renders crisp LCD graphics for waveform displays at 60 Hz refresh.

主要差異化特點
- Highest-memory variant in the DAK169 BGA family (對比PIC32MZ1025DAK169)
- Drop-in tape-and-reel variant for volume assembly (對比PIC32MZ2025DAK169T-V/HF)
- V-temp industrial-extended range versus I-temp (對比PIC32MZ1025DAK169-I/HF)
設計說明
Estimated: at 200 MHz with the graphics controller active and DDR2 in self-refresh, the 169-LFBGA dissipates ~0.8-1.2 W typical. With a typical theta_JA of ~25 C/W for the 11x11 mm LFBGA on a 4-layer JEDEC board, junction temperature rise is ~20-30 C above ambient. Ensure the PCB includes a continuous ground plane under the BGA and thermal vias in the center balls for sustained DDR2 throughput workloads.
Route the DDR2 address/command traces with matched lengths within +/-25 mils and the data byte lanes within +/-50 mils per the PIC32MZ Graphics Family datasheet DDR2 controller timing section. Use 100 ohm differential impedance for HS USB and place the 24 MHz crystal within 5 mm of the XTAL pins with a guard ring to reduce EMI coupling into the graphics data bus.
Do not assume all PIC32MZ DAK variants share the same Flash size - the PIC32MZ1025DAK169 family members have only 1 MB Flash, which is half the PIC32MZ2025DAK169 capacity. If migrating downward, audit the linker script and unused-function declarations; migrating upward (e.g., 1064 -> 2025) is safer since the larger Flash simply leaves unused space.
Decouple the PIC32MZ2025DAK169-V/HF with a 10 uF bulk capacitor plus four 0.1 uF ceramics placed within 3 mm of the package power balls. The BGA's center balls are typically power/ground; connect them to internal planes with multiple small thermal vias (0.2 mm drill, 0.4 mm pad) to reduce inductance and improve thermal dissipation.
