The 80 MHz core delivers up to 1.56 DMIPS/MHz (approximately 125 DMIPS total) and supports single-cycle multiply and hardware divide. The architecture uses a 5-stage MIPS32 pipeline with separate instruction and data Flash buses for zero-wait-state execution from on-chip Flash at 80 MHz. The integrated DMA controller moves data between peripherals and memory without CPU intervention, freeing MIPS for application code. The USB OTG controller with integrated PHY eliminates the need for an external transceiver. Typical applications include USB peripherals and human-interface devices (HID), embedded Ethernet-connected sensors, industrial control and HMI panels, data loggers, point-of-sale terminals, and medical instruments requiring USB connectivity. The wide 2.3V to 3.6V supply range supports battery-powered and 3.3V regulated systems. Design consideration: the 100-pin TQFP footprint requires careful PCB layout, with 0.5 mm pitch and exposed thermal pad handling. Decoupling capacitors should be placed close to each VDD/VSS pair, and the USB DP/DM traces must be routed as a 90-ohm differential pair per USB 2.0 specification.

Typical applications include industrial Ethernet gateways, USB device controllers, building automation nodes, point-of-sale terminals, medical monitoring devices, and embedded web servers. The integrated Ethernet MAC significantly reduces BOM cost versus external PHY-based designs, while the USB OTG controller enables both host and device roles in a single interface. Design with care for high-speed signal integrity. Place a 0.1 uF decoupling capacitor adjacent to every VDD/VDDCORE pin pair, with a bulk 10 uF tantalum capacitor at the regulator output. Route the Ethernet MII/RMII traces as a 50 ohm controlled-impedance group, and place the 25 MHz crystal within 200 mils of the OSC1/OSC2 pins to minimize jitter.

PIC32MX675F256LT-80V/PF

PIC32MX675F256LT-80V/PF - 80MHz 32-bit MCU w/ 256KB Flash & Ethernet

The Microchip Technology PIC32MX675F256LT-80V/PF is a 32-bit MIPS M4K microcontroller operating at 80 MHz with 256 KB Flash and 64 KB SRAM, housed in a 100-pin TQFP package. It integrates a 10/100 Mbps Ethernet MAC, USB-OTG full-speed, two I2C and SPI peripherals, five UARTs, a 16-channel 10-bit ADC, and a Parallel Master Port for external bus interfacing. A 32-bit microcontroller (MCU) is an embedded processor with on-chip Flash, SRAM and peripherals that executes firmware directly from non-volatile memory. PIC32MX devices use the MIPS32 M4K core and sit in the broader hierarchy of microcontrollers -> embedded processors -> semiconductors, with a focus on connectivity-rich applications such as industrial control, consumer electronics and connected appliances. The PIC32MX5/6/7 family specifically targets an integrated devices market, where on-chip MAC and USB-OTG reduce BOM cost. Key features of this part include 80 MHz core / 50 MHz peripheral bus operation, 256 KB Flash, 64 KB RAM, a DMA controller with 8 channels, a 10-bit ADC up to 1 Msps with 16 channels, two comparators, five 16-bit timers, and a Real-Time Clock/Calendar. The Ethernet MAC supports RMII/MII PHY interfaces for 10/100 Mbps full-duplex operation. A full-speed USB-OTG controller with on-chip transceiver eliminates the need for an external PHY. The architecture combines a Harvard-style MIPS M4K core with a multi-vector interrupt controller and a Peripheral Pin Select (PPS) mapping engine that remaps digital peripherals to virtually any I/O pin. The 100-pin TQFP exposes 53 I/Os, of which most are 5V-tolerant in input mode, simplifying interfacing to legacy 5V logic. An integrated voltage regulator supports 2.3V-3.6V single-supply operation, enabling direct Li-Ion or 3.3V regulated designs. Typical applications include industrial Ethernet gateways, USB-OTG device controllers, HMI panels, point-of-sale terminals, and home/building automation controllers. The combination of Ethernet, USB and multiple serial interfaces suits connected embedded systems with mixed communication needs. When designing with this device, ensure the 80 MHz part is paired with an 80 MHz-rated Ethernet PHY (such as the KSZ8041) and that PCB layout follows MII trace-length guidelines. Decoupling requires at least one 0.1 uF ceramic capacitor per power pin plus a bulk 10 uF capacitor on VDD.

PIC32MX675F256LT-80V/PT

PIC32MX675F256LT-80V/PT - 80MHz 32-bit MCU, 256KB Flash, USB-OTG/Ethernet | Microchip

The Microchip Technology PIC32MX675F256LT-80V/PT is a 32-bit MIPS MCU from the PIC32MX5/6/7 family featuring 256KB Flash, 64KB RAM, integrated 10/100 Ethernet MAC, USB-OTG, and an 80 MHz maximum operating speed, housed in a 100-pin TQFP (12x12 mm) package. The device delivers 80 DMIPS of computational throughput from a single-core MIPS32 M4K pipeline and is manufactured on a CMOS process optimized for low-power embedded connectivity. A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a high-performance processor core, program and data memory, and a rich set of peripherals into a single IC. The PIC32MX675 series sits within Microchip's PIC32 family, which targets embedded applications requiring connectivity (USB, Ethernet), graphical HMI (via PMP/parallel master port), and real-time control. In the broader product hierarchy, an MCU is a type of microcontroller -> embedded processor -> semiconductor IC. The "MX" naming convention indicates the MIPS-based M4K core family. Key differentiating specifications include: 256KB (256K x 8) Flash program memory, 64KB SRAM, 83 general-purpose I/O lines, a 16-channel 10-bit ADC at up to 1 Msps, five 16-bit timers, two I2C, two SPI, two UART, USB-OTG (host/device/On-The-Go), 10/100 Mbps Ethernet MAC with MII/RMII interface, two I2S/SPDIF audio interfaces, a Parallel Master Port (PMP) for graphics/parallel memory, and DMA with 8 channels. Supply voltage is 2.3V to 3.6V (nominal 3.3V), and operating temperature range is -40C to +105C (industrial grade "V" suffix). The "T" suffix denotes tape-and-reel packaging, while "80" denotes 80 MHz max frequency. The architecture combines a Harvard-style bus with separate instruction and data paths to Flash/SRAM, allowing simultaneous fetch and data access. Peripherals are connected via a peripheral bus matrix with DMA support, offloading data movement from the core. The 10/100 Ethernet MAC integrates an MII/RMII interface that connects to an external PHY such as the Microchip KSZ8041 or DP83848, eliminating the need for an external network processor. USB-OTG support enables both host and device roles, useful for embedded peripherals that must act as either. Typical applications include industrial Ethernet gateways and PLCs, USB-enabled data acquisition modules, embedded web servers, home automation controllers, medical telemetry devices, point-of-sale terminals, and graphical HMI panels. The combination of Ethernet, USB-OTG, and PMP graphics support makes this MCU particularly suited to networked HMI products where a single chip must handle both communications and display. When designing with this MCU, ensure that the 3.3V supply is well regulated with low noise to avoid corruption of ADC and Ethernet signals. The Ethernet MAC requires an external PHY (e.g., KSZ8041), 25 MHz reference clock, and proper MII/RMII termination. JTAG/ICSP programming requires the standard Microchip 4-wire interface plus a dedicated programming header footprint. This page consolidates distributor pricing, parametric drop-in alternatives in the same TQFP-100 footprint, and design guidance that supplements the manufacturer datasheet for engineers evaluating the PIC32MX675 family.
