Empowering Modern Embedded Systems with Real-Time Control and USB Functionality
The AVR® DU family of microcontrollers (MCUs) adds real-time control and enhanced USB functionality through Core Independent Peripherals (CIPs), which makes it an excellent choice for modern embedded system designs. With easy implementation of a serial-to-USB bridge device, these MCUs address the critical needs of USB-enabled applications to accommodate the addition of USB features at any stage of design. Available in various configurations, the AVR DU MCUs support a wide range of applications with their low-power connectivity, operate at up to 24 MHz and offer up to 64 KB Flash memory.
Getting Started
The AVR64DU32 Curiosity Nano Evaluation Kit is the best platform for rapid prototyping with AVR DU MCUs. This USB-powered kit features an on-board programmer/debugger that seamlessly integrates with the MPLAB® X Integrated Development Environment (IDE). With its small form factor, the AVR64DU32 Curiosity Nano Evaluation Kit is excellent for breadboard soldering. You can also combine it with the Curiosity Nano Base for Click boards™, which features multiple mikroBUS™ sockets to add sensors, actuators or communications interfaces easily from Mikroelektronika’s extensive selection of Click boards.
The AVR64DU32 Curiosity Nano features two USB Type-C® connectors, one for programming and debugging, and one connected to the AVR64DU32’s USB 2.0 full-speed peripheral.
Efficient Industrial Control With Seamless USB Firmware Updates
The AVR DU family of MCUs uses CIPs and USB 2.0, along with an Event System and Configurable Custom Logic (CCL), to provide efficient data transfer and noise immunity for industrial applications. These MCUs offer seamless USB updates and TTL-compatible pins for secure, uninterrupted functionality. Their USB stack, which is configurable via MPLAB® Code Configurator (MCC), supports multiple device classes and powers versatile applications like charging and system upgrades.
The AVR DU MCUs incorporate the Program and Debug Interface Disable (PDID) feature and disable the programming and debug interfaces after finalizing the application to facilitate secure boot processes. This security measure protects against firmware tampering and unauthorized access, which makes these MCUs an excellent choice for security applications.
Functional Safety Ready for Safety-Critical Applications
The AVR DU family of MCUs complies with the IEC 61508 and ISO 26262 functional safety standards, which makes them an excellent choice for safety-critical industrial and automotive applications. We offer an MPLAB XC8 Functional Safety Compiler License, which is a TÜV SÜD-certified compiler package that supports our 8-bit PIC® and AVR MCUs and simplifies the development of products that need to comply with functional safety standards. We offer comprehensive documentation, including FMEDA reports and safety manuals. Contact one of our local sales offices or your authorized distributor for additional information.
