Microchip PIC32MX795F512L-80I/P 32-bit Microcontroller Overview and Application Guide
The Microchip PIC32MX795F512L-80I/P represents a high-performance member of the PIC32MX family, built around a MIPS32® M4K® core capable of operating at up to 80 MHz. This 32-bit microcontroller (MCU) is engineered to deliver a powerful blend of processing performance, large memory capacity, and a rich set of integrated peripherals, making it an ideal solution for complex embedded applications ranging from industrial control and automation to advanced consumer devices.
At the heart of this MCU lies its core, which can execute Dhrystone 1.1 DMIPS up to 105 at 80 MHz, providing the computational muscle needed for demanding tasks. It is complemented by a generous 512 KB of Flash program memory and 128 KB of RAM, offering ample space for sophisticated application code and data handling. A key architectural advantage is the use of a multi-layer bus matrix, which allows the core and Direct Memory Access (DMA) controllers to access memory and peripherals simultaneously, significantly enhancing overall system throughput and enabling true parallel operation.
The peripheral set of the PIC32MX795F512L is exceptionally comprehensive. It features connectivity options like a 10/100 Ethernet MAC with dedicated DMA, making it a strong candidate for networked applications. For local communication, it includes multiple UART, SPI, and I2C™ serial communication modules. Analog capabilities are covered by a 10-bit Analog-to-Digital Converter (ADC) with a sampling rate of up to 1 Msps. Furthermore, it is equipped with 5x 16-bit timers/counters and a real-time clock and calendar (RTCC), providing precise timing control.
A standout feature for control applications is its pair of 32-bit Parallel Master Ports (PMP), which facilitate easy interfacing with external memory and parallel devices such as LCDs and graphic controllers. This, combined with its robust performance, makes it suitable for human-machine interface (HMI) systems.
Housed in a 100-pin TQFP package, the PIC32MX795F512L-80I/P is designed for commercial and industrial temperature ranges (-40°C to +85°C). Development is supported by Microchip's free MPLAB® X Integrated Development Environment (IDE) and the Harmony integrated software framework, which simplifies the configuration of the complex peripheral set and accelerates project development.
ICGOOODFIND: The PIC32MX795F512L-80I/P is a powerful and versatile 32-bit microcontroller that excels in applications requiring high-speed processing, extensive memory, and rich connectivity.
