PIC32MZ1024EFH064-I/MR 概述
What is a 32-bit PIC32MZ EF microcontroller? The PIC32MZ EF family is Microchip's premium high-speed MIPS-based MCU line, designed for embedded applications demanding deterministic real-time performance, large memory footprints, and rich connectivity. It belongs to the broader category of 32-bit microcontrollers within the embedded microcontroller hierarchy (32-bit MCU -> MCU -> semiconductor), and the PIC32MZ EF sub-family specifically addresses industrial, automotive, IoT, graphics/HMI, and motor-control market segments. The 'EF' suffix denotes Embedded Connectivity with Floating Point Unit, distinguishing it from the EFH variant without crypto acceleration and the EFF variant without FPU.
Key features include 200 MHz CPU core, dual-panel Flash for live field update, 1 MB program memory, 512 KB SRAM, 4 KB auxiliary Flash, integrated HS USB 2.0 PHY, 10/100 Ethernet MAC, dual CAN 2.0B controllers, a Parallel Master Port (PMP) for graphics, and a 32-channel 12-bit ADC. The 64-pin QFN package offers a 9 mm x 9 mm footprint with 0.5 mm pitch and exposed pad for thermal dissipation, making it suitable for space-constrained designs.
The device operates from 2.3 V to 3.6 V and supports an industrial temperature range of -40 °C to +85 °C. The architecture provides deterministic interrupt latency, a 16 KB instruction cache, and a tightly-coupled memory controller, enabling high-throughput DSP and control loops. Crypto acceleration is intentionally omitted on this 'no-crypto' variant.
Typical applications include industrial IoT gateways, HMI/graphics terminals, motor control and servo drives, automotive telematics, building automation controllers, and connectivity-rich embedded products. The combination of 1 MB Flash and 512 KB RAM makes it well suited to applications running advanced protocol stacks such as TCP/IP, USB HID/CDC, and CANopen simultaneously.
When designing with this device, use MPLAB X IDE with MPLAB Harmony v3 for peripheral drivers and middleware. Allocate decoupling capacitance of 0.1 µF + 1 µF near each VDD pin, and connect the exposed pad to a continuous ground plane for thermal dissipation. The integrated FPU simplifies single-precision floating-point math, eliminating the need for fixed-point scaling in many control algorithms.

典型应用
PIC32MZ1024EFH064-I/MR 适用于 6 应用s: Industrial IoT Gateway, Human-Machine Interface / Graphics Terminal, Motor Control / Servo Drive, Automotive Telematics / Body Controller, Building Automation / HVAC Controller, USB-Connected Embedded Device / Data Logger.
Industrial IoT Gateway
The PIC32MZ1024EFH064-I/MR is well matched to industrial IoT gateways because its 200 MHz MIPS32 M-Class core, integrated 10/100 Ethernet MAC, and HS USB 2.0 PHY eliminate the need for external communication bridges, reducing BOM cost. The 1 MB Flash and 512 KB SRAM accommodate TCP/IP stacks (Microchip's TCP/IP Lite or third-party lwIP), MQTT/SNMP agents, and application logic concurrently. Engineers place this MCU between RS-485 fieldbus transceivers and the Ethernet uplink, routing Modbus, EtherNet/IP, and PROFINET traffic. Compared to a discrete Cortex-M4 + external Ethernet MAC design, this part saves ~$2 in BOM and ~50 mm² of PCB area, at the cost of consuming ~150 mA typical at 3.3 V. Industrial temperature rating supports outdoor and factory deployments.
推荐
Human-Machine Interface / Graphics Terminal
The PIC32MZ1024EFH064-I/MR's integrated FPU and 32-channel 12-bit ADC make it a strong fit for HMI panels driving TFT LCDs via the Parallel Master Port (PMP). The 200 MHz core plus 512 KB SRAM support Microchip's graphics library (Aria) rendering buttons, gauges, and animated icons at 30+ FPS for QVGA/WVGA displays. Placed as the central MCU in a touch-screen operator panel, it interfaces to a touch controller via I2C/SPI while driving the display through PMP. This is preferable to using a separate graphics controller because the FPU accelerates scaling/rotation routines. Power dissipation at 200 MHz with active graphics is approximately 200 mA at 3.3 V, requiring the QFN exposed pad to be soldered to a continuous ground plane.
推荐
Motor Control / Servo Drive
For field-oriented control (FOC) of 3-phase PMSM or BLDC motors, the PIC32MZ1024EFH064-I/MR's IEEE 754 single-precision FPU eliminates the fixed-point scaling overhead that previously dominated control firmware. The 200 MHz core runs the Park/Clarke transforms and SVM at PWM frequencies above 20 kHz with comfortable headroom, while the 12-bit ADC at 40 Msps captures phase currents synchronously. The dual-panel Flash enables live field updates to motor-control firmware without shutting down the drive. In a typical servo drive this MCU sits between the power stage gate drivers and the CAN/Ethernet interface, accepting torque/position commands and closing the current loop at PWM frequency. The 512 KB SRAM allows dual-current-loop + speed-loop state to coexist with the TCP/IP management interface.
推荐
Automotive Telematics / Body Controller
The PIC32MZ1024EFH064-I/MR's dual CAN 2.0B controllers, 200 MHz core, and rich peripheral mix make it suitable for non-safety-critical automotive telematics and body-control modules. The integrated Ethernet MAC supports automotive audio-video bridging (AVB) and diagnostics over IP (DoIP), while CAN interfaces connect to the vehicle's powertrain and body networks. For under-the-hood or high-temperature zones, migrate to the E-grade variant (PIC32MZ1024EFH064-E/MR) rated -40 °C to +125 °C. Power consumption at typical automotive 12 V to 3.3 V regulation is approximately 0.5 W active, easily supplied by automotive-qualified LDO + buck converters. This part's 1 MB Flash accommodates AUTOSAR MCAL drivers and OEM-specific application layers.
推荐
Building Automation / HVAC Controller
The PIC32MZ1024EFH064-I/MR's combination of Ethernet, USB, CAN, multiple UARTs, and 1 MB Flash supports building-automation controllers managing HVAC, lighting, and access-control subsystems. The 200 MHz MIPS32 core runs BACnet/IP or KNX/IP stacks concurrently with control loops for dampers, valves, and VFD coordination. Engineers integrate this MCU as the central building controller, with Ethernet uplink to the building management system and RS-485/Modbus downlinks to field devices. The -40 °C to +85 °C industrial rating supports unconditioned mechanical rooms. Compared to a Cortex-M4 + external PHY design, the integrated Ethernet MAC reduces PCB area by ~30%, valuable for fitting into standard electrical boxes.
推荐
USB-Connected Embedded Device / Data Logger
The PIC32MZ1024EFH064-I/MR's integrated Hi-Speed USB 2.0 PHY and 1 MB Flash make it ideal for USB-connected data loggers and instrument peripherals. The HS USB controller supports 480 Mbps operation in host or device mode, enabling fast data uploads from ADC-equipped data acquisition systems. The dual-panel Flash supports firmware updates via USB while the logger continues sampling. In a typical USB oscilloscope or spectrum analyzer peripheral, this MCU captures data from a parallel ADC, buffers in 512 KB SRAM, and streams over USB to a host PC. Power consumption is approximately 120 mA at 200 MHz with active USB enumeration, easily supplied by bus-powered 5 V to 3.3 V LDO regulators.

设计说明
The PIC32MZ1024EFH064-I/MR requires a clean 3.3 V supply capable of delivering peak current of ~200 mA at 200 MHz core frequency. Place a 0.1 µF + 1 µF ceramic decoupling capacitor pair on every VDD pin (pins 18, 36, 54), plus a 10 µF bulk capacitor near the IC. For noise-sensitive analog measurements, add a ferrite bead between the digital 3.3 V and AVDD rail, with separate decoupling on AVDD (pin 64). Estimated: at VIN=3.3V, ICC typical ~120 mA, so power dissipation ~0.4 W in the QFN package.
The 64-pin QFN (MR) package has an exposed thermal pad (EP) on pin 65 that MUST be soldered to a continuous ground plane for thermal dissipation. Without proper EP soldering, junction temperature can rise above the 125 °C maximum at 200 MHz continuous operation. Recommended thermal layout: at least 6 thermal vias (0.3 mm drill, 0.6 mm pad) under the EP connecting to the inner ground plane. Estimated: with proper EP soldering, theta_JA is approximately 28 °C/W, allowing ~3.6 W dissipation at 70 °C ambient.
For HS USB 2.0 operation at 480 Mbps, route the USB D+/D- traces as a 90 Ω differential pair with controlled impedance, keeping trace length under 25 mm. Place the USB connector within 25 mm of the IC's USB pins to avoid impedance discontinuities. For 10/100 Ethernet, route the MII or RMII signals as 50 Ω controlled-impedance traces, with the external LAN8740C PHY placed close to the IC. The crystal oscillator traces (OSC1/OSC2) should be as short as possible with a guard ring to ground.
Do not confuse the PIC32MZ1024EFH064 (No-Crypto, 64-QFN) with the PIC32MZ1024EFG064 (Crypto, 64-QFN) when ordering — both share the 64-QFN footprint, but firmware using the crypto engine will not work on the EFH variant. Also avoid confusing the I-grade (-40 °C to +85 °C) with the E-grade (-40 °C to +125 °C) when designing for automotive under-hood applications. Programming voltage: the device uses 3.3 V ICSP, not the older 5 V programming voltage of legacy PIC MCUs.
