Microchip PIC32MX795F512L-80V/PF: A Comprehensive Technical Overview

The Microchip PIC32MX795F512L-80V/PF represents a high-performance member of the widely adopted PIC32MX family of 32-bit microcontrollers. Engineered for demanding embedded applications, this MCU combines a powerful processing core with a rich set of peripherals, making it a versatile solution for complex tasks in industrial control, networking, and human-machine interface (HMI) systems.

At the heart of this microcontroller lies the MIPS32® M4K® core, capable of operating at up to 80 MHz, delivering a performance of 1.56 DMIPS/MHz. This robust processing power enables the efficient execution of complex algorithms and real-time operating systems (RTOS). The device is further enhanced by its 512 KB of dual-panel flash memory and 128 KB of RAM, providing ample space for sophisticated application code and data handling. The dual-panel flash architecture allows for live updates (OTA) while executing from the other panel, which is critical for applications requiring uninterrupted operation.

A standout feature of the PIC32MX795F512L is its integrated connectivity portfolio. It includes a 10/100 Ethernet MAC with dedicated DMA, facilitating network-connected applications. For local communication, it is equipped with two CAN (Controller Area Network) modules (CAN 2.0b), making it an ideal choice for automotive and industrial network nodes. Additionally, it offers multiple UART, SPI, and I²C modules, providing extensive options for interfacing with a vast array of sensors, displays, and other peripherals.

The analog capabilities are equally impressive. The MCU features a 10-bit Analog-to-Digital Converter (ADC) with a throughput of up to 1 Msps, supported by a 16-channel multiplexer for precise sensor data acquisition. For control applications, it includes a parallel master port (PMP) and 5x 16-bit timers/counters, offering flexible waveform generation and capture.

The "-80V/PF" suffix denotes an industrial temperature range (-40°C to +85°C) and a 100-pin TQFP package, ensuring reliability in harsh environments. Its low-power management features, including multiple sleep and idle modes, help optimize energy consumption in power-sensitive designs.

ICGOODFIND: The PIC32MX795F512L-80V/PF is a highly integrated and powerful 32-bit microcontroller, distinguished by its exceptional connectivity options (Ethernet, dual CAN) and large memory footprint. Its balance of processing performance, extensive peripheral set, and industrial robustness makes it a compelling choice for developers building the next generation of connected, intelligent embedded systems.
