PIC32MZ1064DAS169-I/6J - 200MHz 32-bit MCU 1MB Flash | Microchip
The Microchip PIC32MZ1064DAS169-I/6J is a 32-bit MIPS microAptiv-based PIC32MZ DA-series graphics microcontroller that delivers MPU-class performance in an MCU form factor, integrating 1MB Flash, 640KB SRAM, an integrated graphics controller and GPU, and an external DDR2 memory interface in a 169-ball LFBGA 11x11 mm package. It runs up to 200 MHz core clock, supports stacked 32 MB or 128 MB DDR2, integrates a 12-bit 18 MSPS ADC with up to 45 analog inputs, and adds CAN 2.0B plus high-speed USB 2.0 for industrial and embedded GUI workloads.
A 32-bit microcontroller (MCU) is a single-chip processor that combines a high-performance CPU core, on-chip Flash program memory, SRAM data memory, and a rich set of analog and digital peripherals (ADC, timers, communication controllers, GPIO). PIC32MZ DA devices sit at the upper end of the MCU hierarchy: they exceed traditional 8/16-bit MCU performance while retaining deterministic interrupt behaviour and low-power modes that distinguish MCUs from application processors. The DA sub-series further integrates a graphics LCD controller and a dedicated 2D GPU, simplifying HMI designs that previously required an external video co-processor.
Key features of the PIC32MZ1064DAS169-I/6J include the MIPS32 microAptiv core with DSP extensions and single-cycle MAC, an integrated DDR2 controller supporting up to 128 MB of stacked DRAM, a graphics LCD controller (up to WVGA), a 2D graphics processor with hardware overlays and alpha blending, a 12-bit 18 MSPS ADC with up to 45 analog channels, two CAN 2.0B modules, Hi-Speed USB 2.0 OTG, Ethernet MAC, six UART, four SPI, and an I2S audio interface. The on-chip DDR2 interface eliminates the need for an external SDRAM chip, reducing BOM and PCB complexity for graphics-rich systems.
Architecturally, the PIC32MZ1064DAS169-I/6J uses a 5-stage MIPS pipeline with branch prediction, hardware multiply-accumulate, and tightly-coupled SRAM. The integrated graphics pipeline can drive parallel TFT panels up to WVGA at 60 fps without CPU intervention, freeing the application processor for HMI logic, communication stacks, and real-time control loops.
Typical applications include industrial HMI panels with touch and graphics, graphical point-of-sale terminals, medical patient monitors with on-screen waveforms, building-automation control panels, automotive infotainment auxiliaries, and ruggedized handheld instruments that demand low BOM and deterministic MCU behaviour. The integrated DDR2 and graphics pipeline make it a strong fit when board space is constrained but display quality cannot be compromised.
When designing with the PIC32MZ1064DAS169-I/6J, use the MPLAB Harmony 3 software framework and follow the PCB layout guidelines in the PIC32MZ DA family datasheet for the DDR2 interface - matched-impedance routing and length matching are mandatory because the LFBGA 11x11 mm package requires microvia or HDI PCB technology.
