PIC32MX675F256HT-80V/PT
PIC32MX675F256HT-80V/PT - 80MHz 32-bit MCU 256KB Flash | Microchip
The Microchip PIC32MX675F256HT-80V/PT is a 32-bit MIPS M4K microcontroller running at up to 80 MHz, integrating 256 KB Flash and 64 KB SRAM with USB-OTG, 10/100 Ethernet MAC, and a 10-bit ADC in a 64-pin TQFP (10x10 mm) package. The 'V' speed grade and -40C to +105C industrial operating range make it suitable for embedded connectivity designs that must operate across commercial and industrial temperature extremes. Per the Microchip product page, the part is supported by MPLAB Harmony integrated software framework.
A 32-bit microcontroller (MCU) is a programmable processor built around a 32-bit data path, typically with on-chip Flash program memory, SRAM, peripherals, and interrupt controller. The PIC32MX series sits in the hierarchy: 32-bit MCU -> embedded processor -> MIPS M4K core -> Microchip PIC32 portfolio. Compared with 8-bit/16-bit MCUs, 32-bit parts provide higher throughput, larger address spaces, and richer peripherals for connected embedded designs.
Key features include 256 KB Flash, 64 KB RAM, USB-OTG (host/device/OTG), 10/100 Ethernet MAC with MII/RMII interface, two I2C, two SPI, two UART, five 16-bit timers, five input-capture and five output-compare modules, a 10-bit 1 Msps ADC with up to 16 channels, and a parallel master port (PMP). The 64-pin TQFP footprint exposes 53 general-purpose I/O pins, leaving several pins dedicated to oscillator, JTAG, and analog functions.
The M4K core executes most instructions in one cycle, providing 1.56 DMIPS/MHz and integer DSP extensions. The Ethernet MAC integrates an MII/RMII interface and the USB-OTG controller adds full-speed and low-speed USB with on-chip transceiver, removing the need for an external PHY for USB. DMA channels offload data movement between peripherals and memory, freeing the CPU for application code.
Typical applications include industrial Ethernet nodes, USB-OTG peripherals (HID, CDC, mass storage, audio), Ethernet-enabled PLCs, HVAC and building automation controllers, and graphical user interfaces using PMP to drive LCDs. Its combination of Ethernet, USB, and 80 MHz MIPS core suits connected industrial and consumer designs.
When designing with the PIC32MX675F256HT-80V/PT, ensure the 2.3-3.6V supply is decoupled with 100 nF + bulk ceramic placed near the VDD/VSS pairs. Configure the JTAG/ICSP pins (TMS, TCK, TDI, TDO) carefully so production programming is not blocked. Use the Ethernet MAC with an external PHY qualified for the target EMI environment.
This page synthesizes distributor pricing, drop-in alternatives, and side-by-side parametric guidance not found on the manufacturer product page alone, allowing engineers to evaluate the PIC32MX675F256HT-80V/PT against alternatives in one view.
