PIC32MZ1024EFF064-I/MR - 200MHz 32-bit MCU 1MB Flash | Microchip
MPN: PIC32MZ1024EFF064-I/MR ✓ Hoạt độngPIC32MZ1024EFF064-I/MR Tóm tắt
A microcontroller (MCU) is a single-chip computer containing a processor core, program memory (Flash), working memory (SRAM), and a rich set of peripherals on one silicon die. MCUs sit at the heart of embedded systems, executing firmware that reads sensors, drives actuators, and communicates over standard buses. The PIC32MZ EF family extends this concept with a MIPS32 microAptiv core that includes a single-precision FPU, MMU, and DSP extensions, enabling fixed-point and floating-point signal processing directly on the controller. This class of device belongs to the hierarchy: microcontroller -> 32-bit MCU -> high-performance connectivity MCU -> embedded processor.
Key features include 200 MHz core speed with hardware FPU and DSP, 1 MB dual-bank Live-Update Flash for field-firmware upgrades, 256 KB SRAM, integrated 10/100 Ethernet MAC, USB 2.0 High-Speed OTG, two CAN 2.0B controllers, an SQI (Serial Quad Interface) for high-throughput external Flash/PSRAM, and 12-bit ADC modules. The 64-pin QFN package exposes multiple UART/SPI/I2C ports and a parallel master port, making the device a strong fit for gateway and HMI designs.
The PIC32MZ EF architecture uses a 5-stage pipeline microAptiv core with branch prediction and a tightly coupled prefetch module that hides Flash latency, sustaining 3.28 CoreMark/MHz. The dual-panel Flash supports Live-Update firmware swapping without downtime, a capability rarely found on Cortex-M competitors.
Typical applications include industrial IoT gateways with Ethernet and Wi-Fi co-processor links, automotive infotainment and CAN clusters, graphics HMI panels driving TFT LCDs, and motor-control boards combining CAN, SQI, and high-speed analog. Design consideration: plan SQI pin mapping early because SQI shares pins with the parallel master port and cannot coexist with that interface. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

Ghi chú thiết kế
The PIC32MZ1024EFF064-I/MR operates from 2.3V to 3.6V. Decouple VDD with at least two 100nF ceramic capacitors placed within 5mm of each VDD pin pair, plus a bulk 4.7uF or 10uF capacitor. The two VDD pins (9 and 56) and two VSS pins (10 and 55) must each be bonded to the power plane with multiple vias to reduce parasitic inductance. Estimated: at 200 MHz with active peripherals, core current can exceed 80 mA during Flash writes, so verify regulator current rating includes margin for programming-up images.
The 64-pin QFN package (9x9 mm) has a center thermal pad that must be soldered to a copper pour of at least 1 square inch (645 sq mm) for thermal dissipation. Without this pad bond, junction temperature can rise 40C+ above ambient at full load, leading to thermal shutdown. Use an array of 9 to 16 thermal vias (0.3 mm drill, 0.6 mm pad) under the exposed pad to conduct heat to the bottom layer. Estimated: thermal resistance theta_JA of the bonded QFN is approximately 28 C/W versus 60+ C/W unbonded.
Place the 12 MHz primary crystal (or external clock) within 5 mm of OSCI/OSCO pins (63 and 64), with the load capacitors (typically 15-30 pF) grounded to the same VSS as pin 55. Keep the crystal traces short and shielded by a ground ring to avoid EMI pickup. For Ethernet RMII mode, the 50 MHz reference clock must be routed with controlled impedance and length-matched with the data lines to within 50 mil. According to the Microchip PIC32MZ EF Family datasheet, improper crystal layout is the most common cause of USB High-Speed compliance test issues.
SQI shares pins with the parallel master port (PMP) on this device. You cannot use both SQI and PMP simultaneously; select one at firmware boot time via the CFGCON register. Also note that the Live-Update dual-panel Flash feature requires both panel erase operations to complete before firmware switchover - interrupt-driven erase aborts may leave the device unbootable, so use the dedicated erase functions in Harmony v3. According to Microchip application note AN1388, SQI pin selection on this device differs from the PIC32MZ EC predecessor.
