PIC32MZ1024EFG064-I/MR 概述
What is a PIC32MZ EF microcontroller? The PIC32MZ EF family is a high-performance 32-bit Flash microcontroller family based on the MIPS32 microAptiv/M-Class core. It integrates a single-precision IEEE 754 Floating Point Unit (FPU), high-speed connectivity peripherals (HS USB, Ethernet, CAN), and advanced analog (12-bit ADC, comparators). Within the Microchip PIC32 portfolio hierarchy: PIC32MX (entry 32-bit) -> PIC32MM (low-power) -> PIC32MK (motor control / analog) -> PIC32MZ EC (connectivity, no FPU) -> PIC32MZ EF (connectivity + FPU). The PIC32MZ EF line targets industrial, IoT, graphics HMI, and motor-control segments.
Key features of this specific -I/MR variant include the 64-pin QFN (MR) industrial-temperature package (-40C to +85C), 1 MB of program Flash, 512 KB of SRAM, integrated HS USB 2.0 PHY, 10/100 Ethernet MAC, dual I2S/SPI interfaces for audio, an integrated graphics controller driving TFT panels up to WVGA, 24 channels of 12-bit ADC at 1 Msps, six UART, four SPI, and four I2C peripherals. The MIPS M-class core with FPU delivers approximately 330 DMIPS and 1.56 DMIPS/MHz.
Architecturally, the PIC32MZ EF combines separate instruction and data Flash banks enabling Live Update firmware field upgrades, a multi-port DMA engine with 8 independent channels for offloading data movement from the core, and a Peripheral Pin Select (PPS) system that remaps most digital peripherals to any GPIO. The 12-bit ADC includes dual Sample-and-Hold for simultaneous sampling, while the 6-bit comparator with 32-level voltage reference enables hardware motor-control loops without CPU intervention.
Typical applications include industrial IoT gateways (Ethernet + TLS acceleration paths), TFT-based HMI panels with graphics and audio, motor-control BLDC/PMSM drives using FOC algorithms (motor-control firmware libraries included), automotive infotainment and telematics subsystems, and connected medical devices requiring FPU for DSP/filtering. The wide peripheral set allows a single chip to replace discrete MCU + Ethernet controller + USB-IF combinations.
When designing with the PIC32MZ1024EFG064-I/MR, plan the PCB layout around the 9x9 mm QFN exposed pad for thermal dissipation and ground return. Use MPLAB Harmony 3 for driver/provisioning stacks; configure the PLL from the 24 MHz primary oscillator for stable operation at 200 MHz. Decoupling requires 100 nF plus 4.7 uF bulk per VDD pin per Microchip reference schematics, and the analog supply AVDD must be star-routed and decoupled separately from the digital VDD.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single source for component evaluation and procurement decisions.

典型应用
PIC32MZ1024EFG064-I/MR 适用于 6 应用s: Industrial IoT Gateway with Ethernet, TFT HMI Touch Panel, BLDC Motor Control with FOC, Connected Medical Device, Automotive Infotainment Sub-System, Smart Home Hub / Edge Gateway.
Industrial IoT Gateway with Ethernet
The PIC32MZ1024EFG064-I/MR's 200 MHz MIPS M-class core with IEEE 754 FPU and integrated 10/100 Ethernet MAC makes it ideal for industrial IoT gateways aggregating sensor data over Modbus TCP, EtherNet/IP, or MQTT. The 1 MB Flash supports full TLS 1.2 stacks plus application logic, while 512 KB of SRAM buffers incoming sensor frames. The 8-channel DMA engine offloads packet handling from the core, and the industrial -40C to +85C temperature range supports factory-floor deployment. Decoupling and routing follow the Microchip reference design with star-connected AVDD to minimize ADC drift in analog sensor interfaces.
推荐
TFT HMI Touch Panel
The PIC32MZ1024EFG064-I/MR's integrated graphics controller drives WVGA TFT panels directly without an external graphics controller, reducing BOM cost and PCB area. The MIPS M-class core with FPU accelerates image compositing and font rendering, while the 512 KB of SRAM holds framebuffer tiles for smooth UI scrolling. The two I2S peripherals route audio to a codec for chime feedback, and the 24-channel 12-bit ADC reads touch-screen coordinates or backlight current sensing. Layout the RGB bus in matched-length tracks and keep the LCD clock away from the Ethernet RMII lines to avoid crosstalk.
推荐
BLDC Motor Control with FOC
The PIC32MZ1024EFG064-I/MR's single-precision FPU executes Field-Oriented Control (FOC) algorithms for BLDC/PMSM motors at loop times under 10 us, while the DSP extensions handle Park/Clarke transforms efficiently. The 6-bit comparator with 32-level voltage reference combined with the 12-bit ADC at 1 Msps enables sensorless BEMF zero-cross detection. The PWM peripheral with complementary outputs and dead-band insertion drives three-phase inverter bridges directly. The Live Update dual-bank Flash allows field firmware upgrades without halting the motor, critical for industrial automation lines.
推荐
Connected Medical Device
The PIC32MZ1024EFG064-I/MR provides the deterministic 200 MHz MIPS core required for medical signal processing such as ECG, SpO2, or pulse-oximetry front-end digitization. The 12-bit ADC at 1 Msps with dual Sample-and-Hold captures simultaneous channel pairs needed for biopotential measurements, and the 1 MB Flash supports USB stack plus graphical user interface for bedside display. While this variant lacks the crypto accelerator, the FPU handles DSP filter chains efficiently. The industrial temperature range supports continuous operation in clinical environments.
推荐
Automotive Infotainment Sub-System
The PIC32MZ1024EFG064-I/MR's combination of Ethernet, USB, and graphics makes it well-suited as a sub-MCU for next-generation automotive infotainment head units, where it handles auxiliary display driving, USB media playback, and network bridging. The TFT controller drives instrument cluster panels directly. While this -I grade is rated -40C to +85C and lacks AEC-Q100, the -E grade variant (PIC32MZ1024EFG064-E/MR) provides -40C to +125C operation for cabin-mounted sub-assemblies. The Live Update Flash enables OTA firmware updates, and the HS USB OTG supports media-stick or phone-tethered connections.
推荐
Smart Home Hub / Edge Gateway
The PIC32MZ1024EFG064-I/MR integrates Ethernet, USB, and multiple UART/SPI/I2C peripherals needed for a smart-home edge hub bridging Zigbee, Z-Wave, Wi-Fi, and Thread radios to IP backhaul. The MIPS FPU accelerates local ML inference on sensor data, while the 1 MB Flash supports TLS, MQTT, and Matter (formerly Project CHIP) stacks. The 512 KB of SRAM buffers concurrent radio traffic, and the Live Update dual-bank Flash supports secure OTA upgrades with rollback. Industrial temperature ensures reliable 24/7 operation in closets or utility rooms.

设计说明
Decouple the PIC32MZ1024EFG064-I/MR per Microchip's reference schematic: a 100 nF X7R ceramic plus a 4.7 uF X5R ceramic placed within 5 mm of every VDD/AVDD pin, with a 10 uF bulk capacitor near the package's exposed pad. Star-route the AVDD pin back to a ferrite-bead-isolated analog supply rail to keep digital switching noise out of the 12-bit ADC. The internal 1.2V VCAP pin (pin 19) requires a 1 uF ceramic low-ESR capacitor to ground; do not omit it - the core logic will not operate without it.
The 64-pin QFN exposed thermal pad must be soldered to a continuous ground plane on the top or bottom layer for thermal dissipation and ground return. Estimated: at 200 MHz full-clock core activity with 3.3V VDD, the device consumes approximately 110 mA typical (366 mW). Without the exposed pad soldered, junction-to-ambient thermal resistance theta_JA exceeds 40 C/W and may cause thermal shutdown at +85C ambient under worst-case loads. Provide at least 100 mm^2 of 2-oz copper flood stitched with thermal vias to the inner ground plane.
Route the 50 MHz RMII Ethernet signals (REFCLK, RXD[1:0], TX_EN, TXD[1:0], CRS_DV) in matched-length traces within 50 mil of each other and isolated from switching digital signals by a ground guard trace. The 24 MHz primary oscillator (pins 26-27) requires a crystal load capacitor network sized to the crystal's CL specification (typically 18-27 pF total load including stray); keep the oscillator traces short and surrounded by ground. USB D+/D- (pins 32-33) need 90-ohm differential impedance with no stubs.
Do not enable both Ethernet and USB HS simultaneously in firmware without checking the peripheral pin select (PPS) mappings - the PPS system has a limited set of mappable pins and conflicts between Ethernet RMII and USB HS can cause silent peripheral failure. The 'No CAN, No Crypto' suffix in the part designation must be honored by your firmware build configuration; using Harmony 3 drivers for CAN or crypto on this device will fail at compile or runtime. Always verify VCAP has its 1 uF capacitor before applying power.
For TFT LCD applications driving the integrated graphics controller, the pixel clock (typically 25-50 MHz) must be routed with controlled impedance (50-ohm single-ended) and matched-length within 100 mils of the sync and data lines. Keep the RGB bus away from the Ethernet RMII traces and the 24 MHz crystal; add a series ferrite bead on the display backlight supply if backlight PWM injection is observed on the analog ADC channels. For motor-control designs, use the comparator output (C1OUT, C2OUT, C3OUT) signals for hardware BEMF zero-cross detection rather than polling via ADC to avoid cycle jitter.
