PIC32MZ2048EFM064T-I/MR 概述
A 32-bit microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory, data memory, and a rich peripheral set in a single chip. The PIC32MZ EF family belongs to the broader category of embedded microcontrollers, which sits within the taxonomy: 32-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. By combining a 200 MHz MIPS Warrior M-class core with a hardware FPU, DSP extensions, and dedicated peripherals (HS USB, Ethernet MAC, CAN, Crypto accelerator), the PIC32MZ EF line targets connected embedded designs where a higher-end ARM Cortex-M3/M4 would otherwise be considered.
Key features include a 200 MHz / 330 DMIPS MIPS Warrior core with IEEE 754 single-precision floating-point unit, 2 MB dual-panel Flash supporting live-update firmware swap, 512 KB SRAM, and integrated cryptographic engines for AES, DES, 3DES, SHA, MD5, and HMAC. High connectivity peripherals include Hi-Speed USB 2.0 (480 Mbps) with on-chip PHY, 10/100 Ethernet MAC with MII/RMII, two CAN 2.0B controllers, six UART/SPI/I2C modules, and a 12-bit ADC with up to 24 channels and 5 MSPS sampling.
The architecture combines a 5-stage pipeline, single-cycle MAC, four 64-bit accumulators, and saturating/fractional math to accelerate audio processing, motor-control loops, and graphics rendering. Dual-panel Flash permits one bank to run code while the other is reprogrammed, enabling fail-safe field updates without service interruption, which is critical for industrial IoT gateways and connected appliances.
Typical applications include industrial IoT gateways with Ethernet/USB connectivity, automotive infotainment HMI panels, motor-control inverter boards, secure connected medical devices, and graphical HMI terminals. On-chip Crypto and live-update Flash are particularly valuable for IEC 62443-compliant industrial nodes and OTA-updatable consumer products.
When designing with this device, allocate at least four PCB layers for the 64-QFN ground/thermal pad and route the Hi-Speed USB differential pair with 90 ohm impedance. Use MPLAB Harmony v3 with the MHC configurator; ensure external 24 MHz primary oscillator and 32.768 kHz secondary oscillator footprints are reserved for USB full accuracy and RTC operation.
This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes that the manufacturer datasheet alone does not present, giving engineers a faster path from selection to prototype.

典型应用
PIC32MZ2048EFM064T-I/MR 适用于 6 应用s: Industrial IoT Gateway with Ethernet/USB, Automotive Infotainment HMI Panel, Motor Control Inverter Board, Connected Medical Device, Graphical HMI Terminal, Secure Field-Updateable Sensor Node.
Industrial IoT Gateway with Ethernet/USB
The PIC32MZ2048EFM064T-I/MR is well-matched to industrial IoT gateways where its 10/100 Ethernet MAC with MII/RMII and Hi-Speed USB 2.0 with on-chip PHY eliminate external transceiver ICs, reducing BOM cost. The 200 MHz MIPS core and 2 MB Flash run MQTT brokers, TLS stacks, and protocol translation firmware, while the hardware Crypto accelerator handles AES/SHA for IEC 62443-style secure links. Dual-panel Flash permits fail-safe OTA firmware updates over Ethernet without service interruption, which is essential for factory-floor nodes. Industrial-grade -40C to +85C operation supports outdoor cabinet and DIN-rail deployments.
推荐
Automotive Infotainment HMI Panel
The PIC32MZ2048EFM064T-I/MR drives medium-resolution TFT HMI panels in automotive infotainment thanks to its integrated graphics peripherals, 12-bit 5 MSPS ADC for touch-screen sensing, and 2 MB Flash storing multi-language UI assets. The 200 MHz MIPS core with hardware FPU accelerates JPEG decode and 2D rendering at 30+ fps, while the dual-panel Flash supports silent firmware image swap during ignition cycles. Six UART/SPI/I2C ports link to CAN bridges and audio CODECs. Designers can route the USB DP/DM pair to a host port enabling media file playback from USB sticks.
推荐
Motor Control Inverter Board
The PIC32MZ2048EFM064T-I/MR is a strong fit for BLDC and PMSM motor-control inverter boards where its 200 MHz MIPS core plus hardware FPU executes Park/Clarke math and space-vector PWM loops well within 10 us cycle times. The 12-bit ADC with 5 MSPS sampling supports current-sense shunt feedback on three motor phases simultaneously, while the 16 DMA channels move ADC samples to RAM without CPU intervention. Six PWM outputs drive 3-phase IGBT bridges, and CAN 2.0B interfaces to the vehicle or industrial CAN bus. Industrial temperature rating suits servo cabinet deployments.
推荐
Connected Medical Device
The PIC32MZ2048EFM064T-I/MR is suitable for connected medical devices such as patient monitors and diagnostic peripherals, leveraging its hardware Crypto accelerator (AES/DES/SHA/MD5) to protect patient data in transit over Ethernet or USB. The 200 MHz core runs clinical signal-processing algorithms including FIR filters and FFT analysis in real time, while the 2 MB Flash stores both firmware and calibration tables. The 12-bit ADC acquires bio-signals (ECG, SpO2) at sample rates suitable for diagnostic-grade resolution. Industrial-grade temperature supports hospital-room ambient conditions.
推荐
Graphical HMI Terminal
The PIC32MZ2048EFM064T-I/MR powers graphical HMI terminals where its 2 MB dual-panel Flash hosts multi-page operator interfaces, while the 200 MHz MIPS core with FPU accelerates PNG decode and 2D rendering at responsive frame rates. The integrated 12-bit ADC reads front-panel buttons and analog sensors directly without an external controller, and the six UART/SPI/I2C ports link to multiple Modbus RTU slaves and CANopen stacks. Hi-Speed USB 2.0 enables fast log export to USB sticks, while Ethernet links to plant MES systems for production tracking.
推荐
Secure Field-Updateable Sensor Node
The PIC32MZ2048EFM064T-I/MR excels in secure field-updateable sensor nodes where its dual-panel Flash and hardware Crypto accelerator combine to deliver signed OTA firmware updates with zero service downtime. The 200 MHz core runs TLS handshake and JSON parsing for cloud telemetry, while the 2 MB Flash stores both application code and a fallback image for rollback on signature failure. The 12-bit ADC digitizes up to 24 sensor channels at 5 MSPS for vibration or acoustic monitoring, and Hi-Speed USB provides direct laptop interface for field maintenance technicians.

设计说明
The 64-QFN (9x9 mm) package has an exposed thermal pad that must be connected to a ground copper pour with at least 16 thermal vias (0.3 mm drill, 0.6 mm pad, 1.0 mm pitch) for proper heat dissipation and ground return. Allocate at least a 6x6 mm copper pour area on the top layer and stitch to inner ground planes with the via array. Failure to solder the thermal pad can cause thermal stress and reduce long-term reliability. (Reference: PIC32MZ EF datasheet layout guidelines.)
The Hi-Speed USB 2.0 DP/DM pair (pins 55/56) requires 90 ohm differential impedance with matched trace lengths (delta under 150 mil). Route the pair over an unbroken ground reference plane and place the 24 MHz crystal within 5 mm of pins OSC1/OSC2 to meet USB Hi-Speed accuracy requirements. Add a ferrite bead on the USB VBUS line if the design sources bus power. (Reference: PIC32MZ EF datasheet USB section.)
The 10/100 Ethernet MAC MII/RMII signals should be length-matched within 50 mil of each other and separated from noisy digital signals by at least 3x trace width. Place the 50 MHz RMII reference clock source within 25 mm of the ETH_REFCLK pin and add a 33 ohm series-termination resistor on RMII clock and control lines if trace length exceeds 50 mm. (Reference: PIC32MZ EF datasheet Ethernet section.)
The PIC32MZ2048EFM064T-I/MR has multiple VDD and VSS pins (1, 12, 38, 49, 62 and 33, 63 respectively, plus the e-pad). Decouple each VDD pin with a 100 nF ceramic capacitor within 3 mm, plus a bulk 10 uF tantalum or ceramic capacitor at the supply entry point. AVDD should be filtered with a ferrite bead or 10 ohm resistor from VDD, with its own 100 nF + 10 uF decoupling pair for low-noise ADC operation. (Reference: PIC32MZ EF datasheet power section.)
Do not omit the 32.768 kHz secondary oscillator (SOSCO/SOSCI, pins 36/37) if RTC, low-power sleep modes, or USB SOF framing are required - the secondary oscillator is the only precision time base in sleep. Configure PPS (Peripheral Pin Select) carefully when remapping multiple peripherals to the same pin; use the MPLAB Harmony v3 Pin Manager to validate unique pin assignments. Always check the fuse configuration in production to disable JTAG if not needed, freeing GPA0-GPA3 for general I/O. (Reference: PIC32MZ EF datasheet configuration section.)
