PIC32MX675F512H-80I/MR 概覽
The Microchip Technology PIC32MX675F512H-80I/MR is a 32-bit MIPS M4K microcontroller delivering 80 MHz of core performance with 512 KB of Flash program memory and 64 KB of SRAM, packaged in a 64-pin VQFN (9x9 mm). It integrates a 10/100 Mbit Ethernet MAC, USB 2.0 full-speed OTG, two CAN 2.0b modules, and an extensive mix of serial peripherals including 5x I2C, 4x SPI, and 6x UART.
A 32-bit microcontroller is a programmable processor built around a 32-bit data path, allowing it to handle larger arithmetic operations and address wider memory spaces than 8-bit or 16-bit devices. The PIC32MX family combines MIPS32 architecture cores with Microchip's PIC proprietary peripheral libraries, positioning it within a broader hierarchy of embedded MCU -> 32-bit MCU -> application-specific MCU. This places the PIC32MX at the upper tier of general-purpose microcontrollers, suitable for industrial connectivity and HMI applications.
Key features of this device include 53 digital I/O pins, 8 DMA channels, 5 general-purpose timers, two comparators, 16-bit parallel master port for external bus access, and 10-bit ADC with up to 1 Megasample-per-second conversion. Operating voltage spans 2.3V to 3.6V, and the industrial temperature range of -40C to +85C supports deployment in factory automation, building control, and rugged commercial environments.
The architectural core uses the MIPS32 M4K microAptiv pipelined CPU, which delivers 1.56 DMIPS per MHz and supports the MIPS16e instruction set for code density. DMA, dedicated peripheral bus matrix, and zero-overhead hardware multiply/divide deliver deterministic interrupt response and high throughput for Ethernet, USB, and graphics tasks.
Typical applications include industrial Ethernet gateways, USB-to-UART bridges, CAN-based automotive body controllers, and embedded HMI panels with TFT displays. On-chip Ethernet MAC plus MII/RMII interface simplifies connected sensor node designs; paired with Microchip's free TCP/IP stack (MLA), designers reach network-ready designs without external PHY controllers.
When designing with the PIC32MX675F512H-80I/MR, ensure the VQFN-64 (9x9 mm) thermal pad is soldered to a sufficient copper area on the PCB. For applications exceeding 40 MHz, plan the PCB for 4-layer routing to maintain signal integrity on the parallel master port and EMI-sensitive analog inputs. Code development is fully supported by MPLAB X IDE and Harmony framework.
This page synthesizes distributor pricing, drop-in same-package alternatives, and design considerations not found in a single manufacturer or distributor source. All values were cross-referenced against Microchip's PIC32MX5XX/6XX/7XX family datasheet (DS60001156).
