PIC32MZ2048EFH064-250I/PT 概述
What is a PIC32 microcontroller? PIC32 is Microchip's family of 32-bit MIPS-based microcontrollers, sitting at the top of the PIC architecture pyramid above PIC16 and PIC24 devices. The PIC32MZ EF subfamily is the connectivity flagship with dual-panel Flash for live-update field upgrades, a single-cycle hardware MAC for DSP, IEEE 754 single-precision FPU, and rich connectivity peripherals - placing this MCU between traditional 32-bit microcontrollers and high-end application processors in capability and integration.
Key features include 252 MHz / 330 DMIPS core performance, four 64-bit accumulators with single-cycle MAC plus saturating and fractional math for DSP workloads, an IEEE 754-compliant hardware FPU for fast single-precision floating point, and a dual-panel Flash architecture that enables live firmware updates without downtime. The 64-pin TQFP package exposes extensive GPIO alongside Hi-Speed USB, 10/100 Ethernet MAC, CAN, SQI, and multiple SPI / I2C / UART interfaces. An industrial-grade -40C to +85C (I-grade) operating range supports harsh-environment deployment per the part's I-temp suffix.
Typical applications include industrial automation controllers, IoT gateways with Ethernet and Hi-Speed USB, automotive infotainment and telematics, HMI / graphics terminals, BLDC and AC motor control, and audio processing. The combination of large memory, hardware FPU, DSP extensions, and on-chip Ethernet / USB makes this MCU a one-chip solution that previously required an MCU plus an external connectivity co-processor.
When designing with this part, allocate careful pin budgeting since the 64-pin TQFP must route USB PHY lines, Ethernet MAC, CAN, SQI Flash, and JTAG simultaneously - the pin-multiplexing table should be reviewed early in the design. The dual-panel Flash enables A/B firmware updates for fail-safe field upgrades, a reliability advantage over single-bank Flash MCUs, and the I-grade temperature range makes the part directly suited to industrial enclosures.

典型应用
PIC32MZ2048EFH064-250I/PT 适用于 6 应用s: Industrial IoT Gateway, Industrial Automation Controller, Automotive Infotainment & Telematics, HMI / Graphics Terminal, BLDC / PMSM Motor Control, Audio Processing / USB Audio Device.
Industrial IoT Gateway
The PIC32MZ2048EFH064-250I/PT is ideal for industrial IoT gateways because its integrated 10/100 Ethernet MAC and Hi-Speed USB 2.0 deliver wired uplink connectivity without external co-processors. Its 2 MB Flash holds a full TCP/IP stack plus TLS, MQTT, and an OPC UA or Modbus application layer, while the 512 KB SRAM comfortably buffers multiple concurrent sockets. The 250 MHz MIPS Warrior core with IEEE 754 hardware FPU accelerates X.509 handshake math and DSP pre-processing on sensor streams. Designers place the MCU between an Ethernet PHY (e.g., LAN8742) and the field bus, using the 64-pin TQFP's rich GPIO to multiplex UART SPI I2C and CAN peripherals at the same time.
推荐
Industrial Automation Controller
In industrial automation controllers, the PIC32MZ2048EFH064-250I/PT drives real-time control loops with deterministic latency because its 250 MHz MIPS pipeline executes single-precision FPU instructions for PID math in single-digit microseconds. Its four 64-bit accumulators with single-cycle MAC accelerate field-oriented control of 3-phase motors, and dual-panel Flash lets installers push firmware updates on the factory floor without halting the line. Industrial -40C to +85C support tolerates unheated cabinet environments, and CAN plus RS-485/UART peripherals integrate directly with existing fieldbus gear in a 64-pin TQFP.
推荐
Automotive Infotainment & Telematics
Automotive infotainment and telematics units leverage the PIC32MZ2048EFH064-250I/PT for its Hi-Speed USB host capability (DRP), 10/100 Ethernet, and CAN 2.0 in a single chip. The hardware FPU accelerates H.264 stream metadata parsing and audio DSP for cabin processing, while 2 MB Flash supports full Linux-style file systems and graphics framebuffers. Designers connect USB to media streaming peripherals, route Ethernet to a router or 4G modem over RGMII, and use CAN for chassis/bus messaging. The 64-pin TQFP simplifies PCB layout versus larger BGA packages, while the I-grade temperature range covers cabin environments up to +85C.
推荐
HMI / Graphics Terminal
Human-machine interface panels rely on the PIC32MZ2048EFH064-250I/PT to drive small TFT displays and touch interfaces while managing industrial protocols over USB and Ethernet. Its 512 KB SRAM holds a graphics framebuffer for resolutions up to WQVGA without external memory, and the 250 MHz core runs Microchip's MPLAB Harmony graphics library smoothly. Designers pair the MCU with an external SQI Flash for asset storage and use the integrated I2S for audio prompts in operator terminals. The 64-pin TQFP exposes enough GPIO to drive a parallel TFT and a resistive touch controller simultaneously in compact panel designs.
推荐
BLDC / PMSM Motor Control
Field-oriented control of BLDC and PMSM motors benefits from the PIC32MZ2048EFH064-250I/PT's DSP extensions, which include four 64-bit accumulators with single-cycle MAC, saturating and fractional math. The 250 MHz MIPS core computes Park/Clarke transforms plus PI regulators in tens of microseconds, while the hardware FPU handles the rotor-flux math. Designers route the 6-PWM outputs through external gate drivers to the power stage and use CAN or UART for command/feedback. Migrating to a dedicated dsPIC33 is recommended only when the algorithm requires extra PWMs or specialty motor-control peripherals beyond the MCU's envelope.
推荐
Audio Processing / USB Audio Device
USB audio interfaces and professional audio mixers use the PIC32MZ2048EFH064-250I/PT as a Hi-Speed USB audio device controller, capitalizing on its on-chip HS USB plus I2S peripherals. The 2 MB Flash fits USB audio class 2.0 firmware, sample-rate conversion tables, and DSP effects, while 512 KB SRAM holds multiple audio buffers with negligible underrun risk. The hardware FPU accelerates biquad filters and dynamics processing, and the SQI interface allows fast streaming from external memory in more complex mixer designs. Industrial -40C to +85C tolerance supports live-sound and studio installations.

设计说明
Power the PIC32MZ2048EFH064-250I/PT from a clean 3.3V rail using an LDO with at least 200 mA headroom; the part can transition into high-current GPIO switching states during peaks. The on-chip core LDO requires stable input - add a 10uF bulk + 100 nF decoupling pair within 5 mm of the VDDCORE pin. Where the system includes USB, ensure the Vbus sense path uses a dedicated divider and not the MCU's analog supply, per the family's power-supply design guide.
Route USB differential pairs (D+/D-) as 90 ohm impedance-matched lines with length matching to within 150 mil; route Ethernet MII/RMII traces length-matched and isolated from noisy GPIO. Place the 12 MHz or 24 MHz primary crystal within 5 mm of the OSC1/OSC2 pins with a clean ground guard ring, per the family reference manual. The 64-pin TQFP allows a single internal ground plane; keep return paths short under all high-speed peripherals.
Pin-multiplexing on the 64-pin TQFP is dense: USB, Ethernet MAC, CAN, SQI, JTAG, and several peripherals compete for the same pins. Plan peripheral selection first, then fix the pin-mapping table before schematic capture; switching peripherals after layout typically forces an expensive re-spin. Reference MPLAB Harmony's pin-manager and the device variant IO matrix at schematic stage to avoid surprises.
Do not skip configuring the FPU in the startup code - if omitted, floating-point exceptions can crash the application. Use the dual-panel Flash live-update feature only after validating the bootloader against the family reference manual's panel-swap procedure. When using the Ethernet MAC, configure the PHY strap and clock direction (RMII vs MII) consistently with the chosen LAN8742 or KSZ8081 PHY hardware settings.
