Microchip PIC32MX695F512L-80I/PT 32-bit Microcontroller Architecture and Application Guide
The Microchip PIC32MX695F512L-80I/PT represents a powerful and versatile member of the PIC32MX family of 32-bit microcontrollers, built around the industry-standard MIPS32® M4K® core. This device is engineered to deliver a high-performance, feature-rich solution for complex embedded applications, balancing processing power with peripheral integration and power efficiency.
Architectural Overview
At the heart of this microcontroller lies the efficient 80 MHz MIPS32 core, capable of delivering up to 1.56 DMIPS/MHz. This performance is crucial for handling computationally intensive tasks, real-time processing, and running substantial software stacks or an RTOS. The core is supported by a sophisticated bus matrix that allows concurrent access to memory and peripherals by the CPU and DMA controllers, maximizing data throughput and minimizing processing bottlenecks.
A key feature of its architecture is the 512 KB of dual-panel Flash memory and 128 KB of RAM. The dual-panel Flash design enables live update capabilities, allowing firmware to be programmed in one panel while executing code from the other, which is essential for applications requiring fail-safe operation and over-the-air (OTA) updates.
The peripheral set is exceptionally comprehensive. It includes a 10/100 Ethernet MAC with dedicated DMA, making it an ideal choice for networked applications. For connectivity, it offers two USB 2.0 OTG modules (host/device/OTG), a CAN 2.0b module, and multiple UART, SPI, and I2C™ serial communication modules. Analog capabilities are addressed with a 10-bit ADC capable of 1 Msps sampling rate. Furthermore, it features hardware for cryptographic acceleration, supporting AES, 3DES, SHA, and MD5 algorithms, which is vital for securing connected devices.
Application Guide
The combination of high performance and extensive peripherals opens the door to a vast array of applications.
Industrial Control and Automation: The integrated Ethernet MAC and CAN bus are perfectly suited for factory communication networks and industrial control systems. The microcontroller can act as a programmable logic controller (PLC), a gateway, or a motor control unit, leveraging its processing power and numerous timers for precise control loops.
Networking and Communication: As a core component in networked sensors, gateways, and embedded servers, the PIC32MX695F512L manages network stacks via its Ethernet controller and communicates with other devices using its multiple serial interfaces. The dual Flash panels are critical for remotely updating firmware securely.
Consumer and Medical Devices: The USB OTG functionality allows the device to act as a host for connecting peripherals or as a device for interfacing with a PC. This, combined with its processing power, makes it suitable for advanced human-machine interfaces (HMI), data loggers, and portable medical diagnostic equipment.
Secure Connected Systems: The hardware crypto engine offloads complex encryption and authentication tasks from the main CPU. This enables the development of secure data loggers, authentication devices, and any product that requires secure communication and data storage without sacrificing system performance.
