PIC32MZ2048EFG064T-I/MR 概述
Key features include 2 MB of Live-Update Flash memory, 512 KB of SRAM, an integrated Floating Point Unit (FPU), high-speed USB 2.0 (HS USB), 10/100 Mbps Ethernet MAC, 4x SPI, 4x I2C, 6x UART, and a 12-bit ADC with up to 24 analog inputs. The device operates from 2.3V to 3.6V and includes 8 DMA channels for efficient peripheral data movement.
This device belongs to the PIC32MZ EF Family of microcontrollers, which are high-performance MIPS-based MCUs designed for industrial, automotive, IoT, graphics (HMI), and motor control applications. The 200 MHz core, paired with the FPU, delivers up to 1.65 DMIPS/MHz and supports DSP instructions for audio processing. The PIC32 ecosystem provides an extensive library of application notes and reference designs.
Typical applications include industrial IoT gateways with Ethernet connectivity, automotive HMI displays, motor control inverters, audio processing systems, and graphics-based HMIs. The exposed thermal pad on the QFN-64 package enables improved thermal dissipation in high-utilization designs, while the integrated Ethernet MAC reduces BOM cost for connected embedded products.
When designing with this part, ensure the QFN-64 land pattern includes thermal vias under the exposed pad to maintain junction temperature within specifications. The 2 MB Live-Update Flash supports dual-image firmware updates, allowing safe OTA deployments where one partition is the active firmware and the other receives new code.

典型应用
PIC32MZ2048EFG064T-I/MR 适用于 6 应用s: Industrial IoT Gateway with Ethernet, Automotive HMI Display Controller, BLDC Motor Control Inverter, Audio Processing and Effects Pedal, Smart Home IoT Sensor Hub, Industrial Touchscreen HMI Panel.
Industrial IoT Gateway with Ethernet
An industrial IoT gateway requires deterministic Ethernet connectivity plus sufficient Flash for MQTT/TLS stacks. The PIC32MZ2048EFG064T-I/MR integrates a 10/100 Mbps Ethernet MAC with on-chip PHY interface support, 2 MB Flash for TLS libraries and application firmware, and 512 KB SRAM for network buffers and TCP/IP stacks. At 200 MHz with the hardware FPU, it can run encryption, JSON parsing, and sensor aggregation in real time without external memory. The 64-QFN MR footprint with exposed pad simplifies PCB thermal design inside IP-rated enclosures, while the -40C to +85C industrial temperature range supports factory-floor operation.
推荐
Automotive HMI Display Controller
The PIC32MZ2048EFG064T-I/MR serves as a display controller in automotive HMI clusters and infotainment head units. Its 200 MHz MIPS core with hardware FPU accelerates 2D graphics rendering, while the 2 MB Flash holds instrument cluster graphics assets and the 512 KB SRAM doubles as a framebuffer for small displays. The HS USB 2.0 interface supports phone-mirroring or CarPlay-style connections. Note: this EFG variant does not include CAN, so it pairs with a dedicated CAN-FD transceiver for vehicle network bridging. The 64-QFN exposed pad manages thermal load in enclosed dashboard modules.
推荐
BLDC Motor Control Inverter
Brushless DC motor control drives benefit from the PIC32MZ2048EFG064T-I/MR's 200 MHz throughput and 12-bit ADC sampling rate for field-oriented control (FOC) algorithms. The 8 DMA channels can autonomously stream ADC samples to SRAM without CPU intervention, freeing MIPS for the FOC loop and PWM duty updates. The PIC32MZ EF family's PWM and quadrature encoder interface blocks generate motor timing with sub-microsecond resolution. The exposed thermal pad of the QFN-64 MR package handles sustained computational load during high-duty-cycle operation in industrial drives.
推荐
Audio Processing and Effects Pedal
Audio effects pedals and music equipment use the PIC32MZ2048EFG064T-I/MR for real-time DSP at audio sample rates. The 200 MHz MIPS core with hardware FPU and DSP instructions implements reverb, delay, equalization, and pitch shifting in real time with low latency. The 12-bit ADC and on-chip PWM generators provide 16-bit audio quality through oversampling, while the 512 KB SRAM stores audio buffers and coefficient tables. The HS USB can deliver USB Audio Class device streaming for digital pedal board connectivity, and the 2 MB Flash holds presets, firmware, and a small DSP library.
推荐
Smart Home IoT Sensor Hub
Smart home IoT hubs require a low-power microcontroller with multiple peripheral interfaces for sensors and wireless modules. The PIC32MZ2048EFG064T-I/MR's 4x SPI and 4x I2C buses support simultaneous Zigbee, Thread, BLE, and sensor connections, while the 6 UARTs enable debug, GPS, and cellular module integration. The 2 MB Flash accommodates OTA firmware with full TLS stack plus device-cloud protocol (MQTT/CoAP). The QFN-64 MR package suits compact wall-mount enclosures, and the exposed pad manages thermal dissipation during continuous radio coordination tasks.
推荐
Industrial Touchscreen HMI Panel
Industrial touchscreen HMIs integrate display, touch, and connectivity. The PIC32MZ2048EFG064T-I/MR drives a 4-7 inch LCD via parallel or SPI interface, processes touch coordinates through the ADC, and runs the menu/state-machine logic. The 200 MHz core handles full graphical user interfaces, while the Ethernet MAC and HS USB provide factory-network connectivity for SCADA integration. The 2 MB Flash stores multilingual UI assets and 512 KB SRAM serves as a framebuffer. The 64-QFN exposed pad is critical for fanless panels in sealed industrial enclosures where thermal dissipation is constrained.

关键差异点
- QFN package with exposed thermal pad （对比 PIC32MZ2048EFG064T-I/PT)
- 2 MB Flash with Live-Update dual partition （对比 PIC32MX795F512L (512 KB Flash))
- Integrated HS USB and Ethernet MAC （对比 Discrete USB and Ethernet solutions on lower-end MCUs)
设计说明
The 64-lead QFN (MR) package requires a thermal pad land pattern with an array of thermal vias connecting to the internal ground plane. Estimated: with 4x4 thermal vias of 0.3 mm drill and 1 oz copper fill, thermal resistance from junction to ambient drops by approximately 30-40 percent versus a non-via implementation. Solder the exposed pad for both electrical ground and thermal performance.
Place 100 nF decoupling capacitors as close as possible to each VDD/VSS pin pair. Add a bulk 4.7 uF ceramic and a 10 uF tantalum or polymer cap on the main supply rail near the IC. The PIC32MZ EF family has multiple VDD/VSS pairs (digital and analog); each AVDD/AVSS pin needs its own 100 nF analog-domain decoupling. Estimated: a clean power supply reduces ADC noise floor by approximately 10 dB relative to a poorly decoupled layout.
A common mistake is treating 'EFG' variants as having CAN or Crypto support - they do NOT. Verify the device family code before PCB design. Also, the Live-Update Flash requires firmware to manage the dual-partition boot; if the bootloader is missing or corrupted, the device may appear bricked after an OTA update. Always implement a golden-image fallback in the boot ROM-protected region.
For the 10/100 Ethernet MAC, use 50-ohm controlled-impedance traces on the RMII/MII signals and place the PHY close to the MCU. The HS USB D+/D- traces must be 90-ohm differential, with matched length to within 150 mils. Estimated: improper USB routing causes enumeration failures and reduced HS USB throughput from 480 Mbps to FS USB 12 Mbps fallback rates.
合规信息
