MPN： PIC32MZ1024EFF064T-I/MR ✓ 啟用中PIC32MZ1024EFF064T-I/MR 概覽
A 32-bit MCU (microcontroller unit) is a single-chip computer that integrates a 32-bit processor core, program memory (Flash), data memory (RAM), and a rich set of peripherals such as timers, communication controllers, and analog interfaces. The PIC32MZ EF family belongs to the higher-tier MIPS32 M-Class architecture (hypernym: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS M-Class MCU), balancing deterministic real-time performance with the throughput required for graphics and connectivity stacks.
Key features of the PIC32MZ1024EFF064T-I/MR include a hardware Floating Point Unit (FPU) for single-precision DSP math, a 12-bit ADC with up to 5 MSPS sampling, Hi-Speed USB 2.0 on-the-go, 10/100 Ethernet MAC, two CAN modules, an SQI (Serial Quad Interface) for external Flash, and audio/graphics peripherals. The integrated FPU and DSP extensions accelerate signal-processing tasks, while the 1 MB Flash supports large connectivity stacks such as TCP/IP, TLS, and graphics libraries.
The device operates from a 2.1V to 3.6V supply, supports an industrial -40C to +85C temperature range (I-grade), and uses a 9x9 mm 64-QFN with exposed thermal pad for efficient heat dissipation. Internal PLLs and oscillator circuits simplify clocking, and the wide peripheral mix eliminates the need for external companion ICs in typical IoT gateways or HMI designs.
Typical applications include industrial IoT gateways, HMI / graphics terminals, motor control, USB/Ethernet-connected embedded devices, and audio processing front ends. The 200 MHz core, 1 MB Flash, and 256 KB RAM make it well suited for running a real-time OS or a full connectivity stack. Designers should follow the Microchip PIC32MZ EF family reference manual for pin mapping and supply sequencing to ensure deterministic startup and reliable USB/Ethernet PHY operation.
When designing the PCB, allocate adequate copper area beneath the exposed pad of the 64-QFN to meet thermal and electrical grounding requirements. Decoupling capacitors must be placed close to each power pin pair with a 0.1 uF ceramic in parallel with a bulk capacitor, following the reference schematic in the Microchip development kit.

典型應用
PIC32MZ1024EFF064T-I/MR 適用於 6 應用s: Industrial IoT Gateway, Human-Machine Interface (HMI) Terminal, Motor Control Drive, USB Audio Streaming Device, Connected Medical Device, Embedded Web Server / Industrial Controller.
Industrial IoT Gateway
The PIC32MZ1024EFF064T-I/MR is ideal for industrial IoT gateways because it integrates 10/100 Ethernet MAC and Hi-Speed USB 2.0 OTG on-chip alongside 1 MB Flash and 256 KB SRAM. The 200 MHz MIPS32 M-Class core runs a full TCP/IP + TLS stack plus MQTT or CoAP with deterministic latency. The 2.1-3.6 V supply is compatible with common 3.3 V industrial rails, and the -40C to +85C industrial temperature grade supports deployment in factory-floor enclosures. Place a LAN8720A RMII PHY on the MII/RMII pins and add a 25 MHz crystal to complete the Ethernet interface.
推薦
Human-Machine Interface (HMI) Terminal
The PIC32MZ1024EFF064T-I/MR drives graphical HMI terminals thanks to its hardware FPU, 12-bit ADC, and 1 MB Flash supporting graphics libraries. The 200 MHz MIPS core can refresh a small QVGA/WQVGA TFT without external controllers, while the 256 KB SRAM holds framebuffer plus UI state. The SQI peripheral interfaces external Flash for asset graphics, and the CAN modules connect to industrial sensor networks. Pin compatibility with the broader PIC32MZ EF family allows HMI designs to scale up to EFH variants (2 MB Flash / 512 KB SRAM) when more UI complexity is required.
推薦
Motor Control Drive
The PIC32MZ1024EFF064T-I/MR is suited to motor-control applications where the MIPS DSP extensions, 12-bit ADC, and 200 MHz core combine to deliver high-resolution field-oriented control (FOC) loops. The two CAN modules communicate with motor controllers in networked industrial systems, while the FPU accelerates Park/Clarke transforms and PID loops at sub-microsecond cycle times. The -40C to +85C industrial temperature grade supports deployment in motor enclosures. Connect the ADC inputs to current-sense amplifiers and use PWM outputs paired with gate drivers to drive a 3-phase inverter.
推薦
USB Audio Streaming Device
The PIC32MZ1024EFF064T-I/MR supports USB audio-class streaming via its Hi-Speed USB 2.0 OTG peripheral, achieving sufficient bandwidth for 24-bit / 96 kHz stereo or 48 kHz multi-channel audio. The hardware FPU executes biquad filters and dynamics processing in real time with negligible CPU overhead. The 256 KB SRAM accommodates multiple audio buffers plus a USB stack, while the SQI interface optionally adds an external Flash for firmware updates or sample assets. Implement a 5 V to 3.3 V LDO for USB bus-powered designs.
推薦
Connected Medical Device
The PIC32MZ1024EFF064T-I/MR powers connected medical peripherals such as patient monitors and diagnostic handhelds where Ethernet or USB connectivity, deterministic real-time response, and reliability matter. The 12-bit ADC at 5 MSPS captures bio-signals with adequate resolution for heart-rate and SpO2 front-ends. The 256 KB SRAM runs an RTOS plus TCP/IP stack while maintaining deterministic interrupt latency for safety-critical loops. Note that IEC 60730 / IEC 60601 certification is system-level and depends on full BOM selection.
推薦
Embedded Web Server / Industrial Controller
The PIC32MZ1024EFF064T-I/MR runs an embedded HTTP/HTTPS web server with the 1 MB Flash accommodating a TLS stack plus HTML/CSS/JS assets. The 200 MHz MIPS32 M-Class core services multiple concurrent TCP connections while the 10/100 Ethernet MAC delivers wire-speed throughput. The two CAN buses connect to industrial sensor and actuator networks, allowing the MCU to bridge IT (Ethernet) and OT (CAN) domains. Industrial temperature grade supports deployment in factory cabinets. Mount the 64-QFN with adequate copper thermal relief to dissipate heat under sustained Ethernet activity.

- Integrated Hi-Speed USB 2.0 OTG plus 10/100 Ethernet MAC (對比PIC32MX795 series)

設計說明
The 64-pin QFN (9x9 mm) exposes a thermal pad on the underside that must be soldered to a PCB land of at least equal size with multiple thermal vias to the inner ground plane. Without this, junction-to-ambient thermal resistance rises dramatically, causing thermal shutdown at high CPU loads. Place a 4.7 uF bulk + 100 nF ceramic decoupling pair within 2 mm of each VDD pin pair to suppress switching noise from the internal PLL.
Power sequencing: VDD must ramp monotonically between 0 V and 3.6 V. The PIC32MZ EF family datasheet requires the supply rise time to be less than 300 ms; slower ramps risk latch-up. For USB applications, VUSB must come up after VDD or be tied to VDD via a 1 kOhm resistor to ensure the USB transceiver powers up in a defined state.
Crystal layout: keep the 8-20 MHz primary crystal traces short (under 5 mm) and symmetric. Place the load capacitors (typically 18-33 pF) close to the OSC1/OSC2 pins. For USB designs, the 90 Ohm differential USB DP/DM traces must be length-matched within 150 mil to maintain USB-IF compliance - refer to the Microchip PIC32MZ EF USB design checklist.
Do not leave unused I/O pins floating - configure them as outputs or enable the internal weak pull-up. Floating inputs can draw tens of microamps per pin and cause Errata issues with certain revisions of the PIC32MZ EF silicon. Always check the latest silicon errata document for the specific device revision marked on the package before finalizing the design.
Estimated: When driving an external 50 MHz SDRAM or parallel bus via the EBI, the 32-bit data bus and 16-bit address bus must be length-matched within 200 mil to avoid setup/hold violations. Use a 4-layer PCB with a solid ground plane beneath the bus to control impedance (target 50 Ohm single-ended, 90 Ohm differential). Add 22-33 Ohm series-termination resistors near the MCU driver pins to dampen reflections.
