PIC32MZ2048EFH064-250I/MR - 250MHz FPU MCU 2MB Flash | Microchip
MPN： PIC32MZ2048EFH064-250I/MR ✓ 啟用中PIC32MZ2048EFH064-250I/MR 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory, and programmable peripherals. The PIC32MZ EF line sits in Microchip's high-performance tier above PIC32MX parts, targeting embedded connectivity, graphics, and motor-control applications. The MIPS Warrior M-class core extends the M4K lineage with DSP extensions - four 64-bit accumulators, single-cycle MAC, saturating and fractional math - giving it deterministic signal-processing capability alongside general-purpose control.
Key features of this variant include the integrated FPU for fast single- and double-precision floating-point math, dual-panel Flash architecture enabling live firmware updates without downtime, and a rich peripheral set covering HS USB, Ethernet, CAN, six UART/I2C/SPI interfaces, SQI (Serial Quad Interface) for high-throughput memory expansion, a 12-bit ADC up to 500 ksps, and up to nine timers and nine PWM channels. The 250 MHz core is paired with 16 DMA channels to keep data movement off the CPU.
Architecturally the device uses a Harvard cache with separate 32 KB instruction and data caches, prefetch buffers, and a tightly coupled tightly-coupled memory region for low-latency ISR code. The dual-panel Flash partitions the 2 MB into two independently erasable banks, so one panel can run application code while the other receives an over-the-air (OTA) firmware image, then the roles swap with a controlled reset - the canonical pattern for IEC 60730 functional-safety compliant updaters and for connected industrial controllers that cannot afford scheduled downtime.
Typical applications include industrial Ethernet gateways, HMI/graphics terminals with TFT-LCD driving, motor control FOC stages, automotive telematics, IoT edge nodes, audio processing with USB streaming, and medical monitoring instrumentation. The combination of FPU, large SRAM, and Ethernet/USB makes the part particularly attractive for connected-control products that previously required an external MCU plus DSP or FPGA.
When designing in this part, ensure the 64-pin QFN (MR) thermal pad is soldered to a grounded copper pour of at least 25 mm^2 to keep theta_JA within datasheet limits. Plan oscillator- and PLL-startup timing margins, and reserve one DMA channel for SQI transfers if you attach an external Flash or PSRAM for assets beyond the on-chip 2 MB.

典型應用
PIC32MZ2048EFH064-250I/MR 適用於 7 應用s: Industrial Ethernet Gateway, HMI / Graphics Terminal, Motor Control / FOC Drive, IoT Edge Sensor Node, Audio Processing / USB Streaming, Automotive Telematics, Medical Monitoring Instrumentation.
Industrial Ethernet Gateway
The PIC32MZ2048EFH064-250I/MR integrates a 10/100 Ethernet MAC, 250 MHz MIPS core with FPU, and 512 KB SRAM - a combination that runs a full TCP/IP stack plus application logic on one chip. Its 330 DMIPS throughput lets the same MCU terminate MQTT/SNMP traffic while executing real-time control loops. The 12-bit ADC at 500 ksps and 9 PWM channels support closed-loop control of actuators. Place between PHY and host SoC for protocol translation, using DMA channels to offload packet handling. The dual-panel Flash enables secure OTA firmware updates without gateway downtime.
推薦
HMI / Graphics Terminal
The PIC32MZ2048EFH064-250I/MR's MIPS Warrior core plus 512 KB SRAM and HS USB provide ample headroom for TFT-LCD driving via the parallel PMP and 2D graphics primitives. While the EFH variant lacks the dedicated GPU-like controller of EFG parts, the 250 MHz FPU accelerates image rotation, anti-aliased fonts, and capacitive-touch algorithms. Connect a 480x272 or 800x480 TFT over 16-bit PMP, run Microchip's Harmony graphics library, and stream assets over USB. The 2 MB Flash stores large font tables and multilingual bitmaps on-chip, eliminating external memory cost.
推薦
Motor Control / FOC Drive
Field-oriented control of a 3-phase PMSM or BLDC motor requires sub-microsecond ADC-to-PWM latency; the PIC32MZ2048EFH064-250I/MR's 250 MHz MIPS core plus DSP extensions (single-cycle MAC, 64-bit accumulators) deliver deterministic FOC math without burdening software. Nine PWM channels pair with three independent PWM generators to drive a 3-phase inverter with complementary outputs and dead-band insertion. The 12-bit ADC with 500 ksps samples all three phase currents simultaneously using the ADC7 dedicated core. The FPU simplifies Clarke/Park transformations. Match this with Microchip's MPLAB Harmony Motor Control framework for ready-to-tune PI controllers.
推薦
IoT Edge Sensor Node
For battery-aware IoT nodes, the PIC32MZ2048EFH064-250I/MR's integrated Ethernet and HS USB reduce external component count, while the 250 MHz wake-up latency lets the core sleep aggressively between sensor samples. The 2 MB Flash supports on-device ML inference tables and OTA staging; the dual-panel architecture swaps firmware without interrupting sensor acquisition. The SQI peripheral attaches a low-cost serial NOR Flash for asset storage. With deep-sleep currents under typical PIC32MZ EF levels, the part fits mains-powered smart-home, building-automation, and industrial-sensor hubs.
推薦
Audio Processing / USB Streaming
The PIC32MZ2048EFH064-250I/MR's HS USB port and I2S peripheral make it a natural fit for USB audio devices and DSP effects units. The FPU accelerates biquad filters, FFT analysis, and dynamics processing with sample-rate headroom. Six SPI/I2S lanes let you bridge multiple audio CODECs while the 512 KB SRAM hosts double-buffered audio frames. The 12-bit ADC handles auxiliary analog sensing, and the 2 MB Flash stores presets and firmware. Build USB headphones, studio effect pedals, or audio mixers without an external DSP chip.
推薦
Automotive Telematics
For non-safety-critical automotive telematics (gateway, OBD-II logger, fleet tracker), the PIC32MZ2048EFH064-250I/MR delivers Ethernet, CAN, and USB in one chip - all needed for vehicle network bridging. The 250 MHz core handles CAN-FD parsing and TLS offload; 2 MB Flash stores trip logs. Note: this SKU is industrial grade only; AEC-Q100 projects should choose the explicit automotive variant. The -40C to +85C industrial range covers most cabin environments. The MR QFN package withstands automotive vibration when properly board-mounted.
推薦
Medical Monitoring Instrumentation
Patient monitors, infusion pumps, and portable diagnostic devices benefit from the PIC32MZ2048EFH064-250I/MR's integrated FPU, DSP extensions, and large memory. The DSP MAC instructions accelerate FFT-based heart-rate and SpO2 algorithms, while the FPU simplifies calibration math. The 12-bit ADC at 500 ksps samples multiple biosensor channels; the SQI bus hosts high-density serial NOR for patient data logging. Industrial -40C to +85C covers most clinical environments. Add an external audio CODEC for alarm synthesis and the part becomes a complete patient-monitor brain.

主要差異化特點
- Highest CPU frequency grade in 64-pin MR package (對比PIC32MZ2048ECH064-I/MR)
- Full dual-panel Flash with 2 MB capacity (對比PIC32MZ1024EFH064-I/MR)
- Connectivity-optimized variant with FPU+DSP (對比PIC32MZ2048EFG064-I/MR)
設計說明
Estimated: the 64-pin QFN (MR) exposed thermal pad must be soldered to a grounded copper pour of at least 25 mm^2 to meet the datasheet thermal resistance. Without proper thermal pad soldering, theta_JA rises sharply and the 250 MHz core may throttle under sustained load. Use multiple thermal vias in the pad for vertical heat extraction to inner copper layers. For high-ambient (>60C) enclosures, add copper spreading on outer layers around the pad.
Place decoupling capacitors (100 nF ceramic) within 2 mm of every VDD/VSS pair and a bulk 4.7 uF near the part. The PIC32MZ EF family is sensitive to VDD ripple under high-frequency switching; route the analog AVDD separately from digital VDD with a ferrite bead and star-ground topology. Leave room on the layout for an optional 32.768 kHz crystal footprint for RTC operation even if not used initially - retrofits are costly.
Route the HS USB D+/D- traces as a 90-ohm differential pair with length matching to within 150 mil. The Ethernet RMII traces should be 50-ohm single-ended and matched within 100 mil. Keep the 12-bit ADC traces away from PWM outputs to avoid switching-noise coupling into sensor readings; use a ground guard trace around analog signals. Match the SD-CARD or SQI traces to 50 ohm if high-speed (>50 MHz) is needed.
Common pitfalls include: (1) forgetting the dual-panel Flash requires bootloader setup for live-update use; (2) enabling all peripherals simultaneously exceeds the 250 MHz core's interrupt latency budget - prioritize ISR nesting; (3) not enabling the JTAG/SWD pins correctly leaves the part bricked - use a 4-wire ICD header for first bring-up; (4) assuming FPU availability - older PIC32 tools may not enable FPU by default in project options; (5) using PIC32MX firmware without recompiling - register maps differ between MX and MZ families.
Estimated: at full 250 MHz and 100% peripheral utilization, the PIC32MZ2048EFH064-250I/MR consumes approximately 80-110 mA from 3.3V. Design the 3.3V rail for at least 150 mA continuous. Enable unused peripherals' clocks off via the peripheral clock gating register to reduce quiescent current by 30-40%. During deep-sleep, the part draws microampere-level currents and retains RAM contents if the on-chip FPU/clock gating is properly configured.
