PIC32MZ1064DAB176T-I/2J - 200MHz MCU 1MB Flash LQFP-176 | Microchip
MPN： PIC32MZ1064DAB176T-I/2J ✓ 啟用中PIC32MZ1064DAB176T-I/2J 概覽
A 32-bit microcontroller (MCU) is a system-on-chip that integrates a 32-bit processor core, on-chip memory (Flash + SRAM), and a rich set of peripherals (ADC, USB, CAN, timers, I/O). PIC32 MCUs from Microchip use the MIPS32 microAptiv core, which sits in the microcontroller hierarchy below application processors but above 8/16-bit MCUs, giving developers higher code density, faster arithmetic, and direct support for larger RTOS, TCP/IP stacks, and graphical user interfaces.
Key differentiating features include the integrated 2D graphics processing unit (GPU) and graphics controller with up to 128 MB of external DDR2 DRAM addressable through the External Bus Interface (EBI), 12-bit 18 MSPS ADC with up to 45 analog inputs, High-Speed USB 2.0, CAN, and a peripheral set aimed at industrial control, automotive dashboards, and graphical embedded products. The 200 MHz core delivers 252 DMIPS and 3.28 CoreMark/MHz, matching many Cortex-M4 implementations while bringing dedicated display pipeline hardware.
The device combines a deterministic MIPS microAptiv pipeline with tightly coupled SRAM for low-latency peripheral response. Internal DMA and a dedicated GPU offload rendering tasks from the CPU, allowing 60+ FPS UI updates on WVGA panels with low CPU overhead. The 176-pin LQFP-20x20 footprint also provides generous GPIO and parallel bus pins for memory expansion.
Typical applications include industrial HMI panels with TFT-LCD, automotive infotainment entry-level, smart appliance control panels, medical instrument displays, and IoT gateways needing on-chip graphics. The integrated GPU and DDR2 controller make it competitive with higher-priced Cortex-A designs for simple dashboards.
When designing with the PIC32MZ1064DAB176T-I/2J, ensure the PCB provides adequate thermal dissipation for the 1W max power budget at 200 MHz, and follow the DDR2 PCB layout guidelines in the datasheet for signal integrity. Use the MPLAB Harmony framework for peripheral drivers and the MPLAB ICD 3 / ICD 4 / PICkit 4 for programming and debugging.

典型應用
PIC32MZ1064DAB176T-I/2J 適用於 6 應用s: Industrial HMI / TFT-LCD Control Panel, Smart Home Control Hub with Touchscreen, Medical Instrument Display, Automotive Dashboard (Non-Safety) Infotainment, Industrial IoT Gateway with Local Display, POS Terminal / Kiosk Display Controller.
Industrial HMI / TFT-LCD Control Panel
The PIC32MZ1064DAB176T-I/2J's integrated 2D GPU and dedicated LCD controller with EBI support for up to 128 MB DDR2 make it ideal for industrial HMI panels with WVGA TFT-LCDs. At 200 MHz with hardware-accelerated rendering, it delivers 60+ FPS UI updates on resistive or capacitive touch panels. Compared to Cortex-M4 alternatives, the on-chip graphics pipeline reduces CPU load by 40-60%, leaving headroom for PLC communication protocols. Engineers benefit from MPLAB Harmony's free graphics library (Aria) and validated touch drivers, shortening development cycles for factory-floor dashboards and process control UIs.

Smart Home Control Hub with Touchscreen
For smart home hubs with integrated color touchscreens, the PIC32MZ1064DAB176T-I/2J provides a 200 MHz MIPS32 core, 1 MB Flash for protocol stacks (Zigbee/Wi-Fi/BLE coordination), and integrated graphics to drive 4.3"-7" TFT panels. The Hi-Speed USB 2.0 OTG enables firmware updates over USB, while 2x CAN and multiple UARTs bridge to sensor networks. Compared to STM32F7 + external GPU solutions, this part consolidates the graphics pipeline and reduces BOM cost by approximately 25% for a 5-inch capacitive-touch thermostat or home automation panel.
推薦
Medical Instrument Display
The PIC32MZ1064DAB176T-I/2J suits medical instruments such as portable patient monitors and diagnostic devices with graphical readouts. Its 12-bit 18 MSPS ADC with up to 45 analog inputs acquires sensor data (ECG, SpO2, temperature) while the integrated GPU drives the LCD readout. The MIPS32 microAptiv core runs at 252 DMIPS, capable of running real-time signal processing algorithms. Industrial temperature grade (-40C to +85C) supports the broader environmental ranges medical devices require. Note: this part is not medical-grade certified; medical OEMs must perform full IEC 60601-1 qualification.
推薦
Automotive Dashboard (Non-Safety) Infotainment
For non-safety automotive applications like rear-seat entertainment, climate control displays, or instrument cluster sub-displays, the PIC32MZ1064DAB176T-I/2J provides MPU-class graphics performance in an MCU footprint. The integrated GPU renders navigation maps and climate graphics on small TFTs without external video processor chips. CAN bus interfaces connect to the vehicle network. Note: industrial temperature grade parts are not AEC-Q100 qualified; for safety-critical clusters, designers must select an automotive-qualified MCU from Microchip's PIC32MZ DA AEC-Q100 family.
推薦
Industrial IoT Gateway with Local Display
The PIC32MZ1064DAB176T-I/2J pairs an industrial-temperature 200 MHz MIPS core with rich connectivity for IIoT edge gateways that need a local status display. Hi-Speed USB 2.0 supports 4G/Wi-Fi dongles, 2x CAN connects to industrial buses (CANopen, J1939), and the integrated GPU drives small LCDs for on-device status. 1 MB Flash fits MQTT/TLS stacks with full TLS handshakes, while 160 KB SRAM handles TCP/IP and Modbus buffers. Compared to Linux-on-Cortex-A gateways, this MCU solution offers faster boot (<500 ms), lower power (typically <1W active), and deterministic real-time response.
推薦
POS Terminal / Kiosk Display Controller
For point-of-sale terminals and self-service kiosks with graphical touchscreens, the PIC32MZ1064DAB176T-I/2J delivers MPU-like display performance with MCU simplicity. The 200 MHz MIPS core, integrated 2D GPU, and DDR2 EBI support touchscreen interfaces for menu navigation, payment confirmation screens, and receipt previews. USB 2.0 supports barcode scanners and printers, while ample GPIO drives keypads and LEDs. Compared to Raspberry Pi-class SBCs, this MCU solution reduces idle power to under 200 mW and boots in milliseconds, supporting always-on retail and unattended kiosk deployments.

主要差異化特點
- Integrated 2D GPU + DDR2 EBI in MCU footprint (對比STM32F429 Cortex-M4 + external GPU)
- Higher Flash density (1 MB) at this price tier (對比PIC32MX795F512L-80I/BG)
- Mature MPLAB Harmony ecosystem with HMI graphics libraries (對比Bare-metal or third-party RTOS on competitor MCUs)
設計說明
PIC32MZ DA devices at 200 MHz can draw up to ~250 mA from the 3.3V rail during peak CPU + GPU activity. Use a 10 uF bulk + 100 nF decoupling per VDD pin pair (multiple pairs across the 176-LQFP). Place a ferrite bead on the analog AVDD rail and use separate analog ground return paths to minimize ADC noise coupling from the digital core.
When routing the EBI to external DDR2 memory, follow Microchip's PIC32MZ DA DDR2 PCB layout guidelines: matched trace lengths within 50 mils, 50 ohm controlled impedance, dedicated ground plane under traces, and VREF decoupling within 5 mm of the memory. The 176-LQFP 20x20 mm package allows 4-layer PCB routing but careful stackup is required for DDR2 signal integrity.
Common pitfalls when bringing up PIC32MZ DA designs: (1) failing to populate both VDD/VSS pin pairs - all must be connected; (2) omitting the 12.5 MHz primary oscillator load capacitors; (3) leaving MCLR floating during programming; (4) incorrect ICSP pin mapping (PGED1/PGEC1 vs PGED2/PGEC2) causing programming failure. Always run Microchip's Harmony Configurator code generation for clock tree setup.
Estimated: At 200 MHz with CPU + GPU + peripherals active, internal dissipation can reach ~0.8 W. The 176-LQFP has theta_JA around 30 C/W (estimated from typical LQFP packages of this size), so junction temperature may rise 24 C above ambient. Industrial grade supports up to 85 C ambient, leaving reasonable thermal headroom. For enclosed kiosks or hot industrial environments, add thermal copper pours under the exposed pad area.
Keep analog ADC input traces away from digital switching signals. Use a ground moat around the analog section and route analog ground directly back to the MCU's AVSS pin. Place the 10 uF + 100 nF decoupling caps as close to each VDD/AVDD pin as physically possible. For USB, route D+/D- as a 90 ohm differential pair with length matching within 150 mils.
