What is a PIC32MZ microcontroller? A PIC32MZ is a 32-bit RISC microcontroller built on the MIPS microAptiv core, designed by Microchip Technology for embedded connectivity applications. In the broader taxonomy it sits at MCU > 32-bit MCU > RISC MCU > connectivity MCU > high-performance MCU, and is positioned for applications that need DSP, Ethernet, USB, and large memory footprints in a single device. The 'EC' family specifically emphasizes Ethernet connectivity alongside the full peripheral suite, while the 'H' flash-density suffix denotes 1 MB of program memory.
Key differentiating features of this part include 200 MHz / 330 DMIPS compute performance with single-cycle MAC and four 64-bit accumulators for DSP workloads, microMIPS mode delivering up to 35% code compression to maximize the 1 MB Flash, and a Memory Management Unit (MMU) supporting embedded OS execution such as FreeRTOS or openRTOS. The dual-panel Flash architecture allows in-field firmware swap without downtime.
Typical applications span industrial IoT gateways, Ethernet-enabled PLC controllers, automotive infotainment sub-systems, building automation bridges, and audio/graphics HMI panels. When designing, ensure the trace impedance for the Ethernet MAC differential pair meets IEEE 802.3 requirements, and provide a 24 MHz crystal reference within the recommended load capacitance tolerance to keep the USB HS PLL locked.

典型應用
PIC32MZ1024ECH064-I/PT 適用於 7 應用s: Industrial IoT Gateways with Ethernet, Audio/Graphics HMI Panels, Automotive CAN Node Controllers, Building Automation Bridges, Portable Medical Data Loggers, USB Device Peripherals and HID, Smart Energy Metering.
Industrial IoT Gateways with Ethernet
The PIC32MZ1024ECH064-I/PT is purpose-built for industrial IoT gateways because it integrates a 10/100 Ethernet MAC alongside 1 MB dual-panel Flash and 512 KB SRAM in a single 64-pin TQFP. Its microAptiv core at 200 MHz runs FreeRTOS plus a full TCP/IP stack with TLS, while the dual-panel Flash enables fail-safe OTA firmware upgrades in unattended deployments. The wide 2.3-3.6 V supply tolerance supports 3.3 V industrial rails directly.
推薦
Audio/Graphics HMI Panels
The PIC32MZ1024ECH064-I/PT drives audio/graphics HMI panels through its PMP parallel master port for TFT displays and I2S interfaces for codec audio. The 200 MHz microAptiv core delivers enough throughput to render frame buffers and decode compressed audio streams in parallel, while 512 KB SRAM holds double-buffered frame data without external memory. The 24-channel 10-bit ADC handles touch and analog sensor inputs alongside display refresh.
推薦
Automotive CAN Node Controllers
The PIC32MZ1024ECH064-I/PT serves automotive CAN node controllers with its CAN 2.0B peripheral and automotive-grade temperature variants. Although the I-grade itself is industrial, the silicon platform supports CAN-FD through firmware with sufficient 200 MHz CPU headroom. Designers use it in body controllers, HVAC modules, and infotainment sub-systems where Ethernet and CAN coexist. For AEC-Q100 qualification, consider the AEC-Q100 equivalent part number from Microchip.
推薦
Building Automation Bridges
The PIC32MZ1024ECH064-I/PT excels in building automation bridges because of its multiple UART (with LIN/IrDA), SPI, I2C, and CAN interfaces that map to HVAC, lighting, and security subsystems. The 1 MB Flash holds BACnet, Modbus, and proprietary building protocols concurrently. With 200 MHz compute, the MCU handles protocol translation with sub-millisecond latency, and the dual-panel Flash allows field updates without downtime.
推薦
Portable Medical Data Loggers
The PIC32MZ1024ECH064-I/PT serves portable medical data loggers thanks to its 24-channel 10-bit 500 KSPS ADC and 512 KB SRAM that buffers patient waveforms. Its low-power Run, Idle, and Sleep modes managed by the microAptiv core extend battery life in wearable monitors. The MMU enables secure OS partitioning for FDA-grade software architectures. The SQI interface supports fast external Flash for long-term recording.
推薦
USB Device Peripherals and HID
The PIC32MZ1024ECH064-I/PT supports USB peripherals through its Hi-Speed USB 2.0 host/device/OTG controller. Engineers deploy it in industrial HIDs, barcode scanners, and USB-to-Ethernet bridges. The 1 MB Flash accommodates USB class driver stacks plus application code, and the 200 MHz CPU executes USB interrupt service routines with low latency. The dual-panel Flash enables in-field USB bootloader updates.

Smart Energy Metering
The PIC32MZ1024ECH064-I/PT is well-suited for smart energy metering with its dual ADC capability (up to 24 channels at 500 KSPS) for voltage/current sensing, Ethernet connectivity for AMR/AMI reporting, and 1 MB Flash for metering algorithm libraries. The MMU and FreeRTOS support enable secure DLMS/COSEM stack execution. The industrial temperature grade -40 C to +85 C handles outdoor meter enclosures.

主要差異化特點
- Dual-panel Flash for live firmware updates (對比PIC32MX795F512L-80I/PT)
- 2.5x higher CPU performance and DSP extensions (對比PIC32MX795F512L-80I/PT)

設計說明
Estimated: The PIC32MZ1024ECH064-I/PT core draws approximately 70 mA at 200 MHz with all peripherals active from a 3.3 V rail, giving ~230 mW active dissipation. Use a low-impedance 3.3 V LDO such as the MCP1700 or a switching regulator with < 50 mVpp ripple to avoid USB PLL jitter. Decouple each VDD/VDDIO pin with a 100 nF ceramic plus a bulk 4.7 uF tantalum within 10 mm of the package.
Route the Ethernet TX/RX differential pair as a 100 ohm differential controlled-impedance trace with continuous ground reference beneath. Keep the 24 MHz primary crystal traces short and surrounded by a ground guard ring to meet USB Hi-Speed eye-diagram compliance. The TQFP-64 10x10 mm package requires 4-layer PCB at minimum for proper thermal spreading.
Do not confuse the PIC32MZ1024ECG064 (G suffix = lower Flash) with the PIC32MZ1024ECH064 (H suffix = 1 MB Flash); same family and pinout but different memory maps. Do not enable the USB HS PLL before the primary oscillator is stable, or the USB peripheral may hang. Always hold the MCLR pin high through a 10 kohm pull-up to prevent spurious resets during power-up ramps.
Place the 32.768 kHz RTCC crystal and load capacitors within 5 mm of the SOSCI/SOSCO pins, and isolate the 32 kHz traces from noisy switching nodes. The dual-panel Flash uses both panel-select pins; route both PB1/PB2 selection signals and ensure they are not pulled low at boot to enter live-update mode unintentionally.
