PIC32MZ1025DAK176T-V/2J - 200MHz 32-bit MCU Graphics LQFP-176 | Microchip
MPN： PIC32MZ1025DAK176T-V/2J ✓ 啟用中PIC32MZ1025DAK176T-V/2J 概覽
A 32-bit microcontroller (MCU) is an integrated circuit combining a processor core, program memory (Flash), data memory (SRAM), and a rich set of peripherals on a single die. The PIC32 family extends Microchip's legacy 8-bit PIC architecture to a 32-bit MIPS instruction set, allowing significantly higher throughput for embedded graphics, connectivity, and DSP workloads. Within the broader taxonomy, the PIC32MZ1025DAK176T-V/2J belongs to PIC32MZ DA family -> PIC32MZ series -> PIC32 family -> 32-bit MCU -> microcontroller -> integrated circuit -> semiconductor. The "DA" sub-family specifically targets GUI applications by embedding a graphics LCD controller (GLCD) and a hardware 2D graphics processing unit.
Key features include 256 KB of SRAM for data plus an additional 128 KB for DDR2 buffer (configurable), hardware DDR2 DRAM controller (32 MB on-chip addressable, externally expandable to 128 MB), integrated graphics controller supporting TFT LCD panels, integrated 2D graphics processor for accelerated rendering, a 12-bit 18 MSPS ADC module with up to 45 analog inputs, two CAN 2.0b modules, Hi-Speed USB 2.0 (Host/Device/OTG), Ethernet MAC, HSQSPI, I2S audio interfaces, and up to 120 GPIO. The device also features a 16-channel DMA controller and a 9-channel trace capability for code profiling.
Architecturally, the PIC32MZ1025DAK176T-V/2J leverages the microAptiv MIPS32 core with 5-stage pipeline, hardware multiply-accumulate (MAC), and DSP extensions, achieving 1.56 DMIPS/MHz. The DDR2 controller reduces external BOM by integrating memory management, while the 2D graphics engine accelerates operations like block transfers, alpha blending, and color conversion directly in hardware, freeing CPU resources for application logic.
Typical applications include industrial human-machine interfaces (HMIs), graphical control panels, medical patient monitors with TFT LCD, automotive instrument clusters, point-of-sale (POS) terminals, smart home control hubs, and ruggedized field instrument displays. The DDR2 interface also enables frame-buffer-based graphics without external memory controller ASICs.
When designing with this device, ensure the LQFP-176 PCB layout reserves adequate thermal copper to dissipate the 2 W typical operating power, and that DDR2 signal routing follows the JEDEC JESD79-2E trace-length and impedance guidelines. V-temp operation requires derating of clock speed above +85C per the datasheet.

主要差異化特點
- Higher temperature rating vs I-temp alternative (對比PIC32MZ1025DAK176T-I/2J)
- Same die as I-temp part - zero firmware changes when substituting (對比PIC32MZ1025DAK176T-I/2J)
- Mature silicon revision (K) versus newer B revision alternatives (對比PIC32MZ1025DAB176T-I/2J)
設計說明
Estimated: at full 200 MHz operation with peripherals enabled, the PIC32MZ1025DAK176T-V/2J dissipates approximately 1.5-2.0 W. The 176-LQFP package has a typical theta_JA of ~30 C/W, yielding a junction temperature rise of 45-60C above ambient. For V-temp operation at +105C ambient, ensure PCB thermal copper (at least 25 sq cm of inner/outer ground plane connected to the thermal pad via vias) keeps junction below +125C. A small clip-on heatsink is recommended for enclosed HMI enclosures without airflow.
DDR2 signal routing must follow JEDEC JESD79-2E trace-length matching: DQ-DQS within +/-25 mils, byte-lane within +/-50 mils, clock to data within +/-100 mils. Route DDR2 signals on inner layers with reference ground planes both above and below; use 50 ohm controlled impedance (single-ended) and 100 ohm differential for clocks. Place 0.1 uF + 10 uF decoupling capacitors within 100 mil of each VDD pin, and a 4.7 uF bulk capacitor near the DDR2 supply pins.
Do not confuse the K (DAK), B (DAB), and S (DAS) silicon revisions - they have different errata sheets despite sharing the same datasheet family document. The DDR2 controller requires specific PLL configuration before DDR2 initialization or the controller will lock up. V-temp parts (this MPN) must be derated above +85C ambient - consult the PIC32MZ DA datasheet thermal derating curves. Always run MPLAB Harmony Configurator for proper clock tree and peripheral initialization.
Separate analog and digital ground planes; the PIC32MZ1025DAK176T-V/2J has dedicated AVSS pins that should connect to a single-point ground tie. The TFT LCD data bus (typically 24-bit RGB) should be routed with matched trace lengths to avoid color-channel skew on the display. Hi-Speed USB DP/DM traces require 90 ohm differential impedance and max 4 inches length with no stubs.
