Simplifying Safety in Critical Applications with New MCUs
Transforming Safety in Embedded Applications
In today's fast-paced technology landscape, engineers are continuously striving to create systems that not only meet safety requirements but also do so with minimized costs and complexity. Microchip Technology has stepped up to the plate by unveiling a new family of microcontrollers designed specifically for this challenge. This new offering, known as the AVR SD family, centers around providing robust solutions for safety-critical applications.
Introduction to the AVR SD Family of Microcontrollers
The AVR SD microcontrollers have been engineered to support applications that require stringent safety assurances. These advanced MCUs include built-in functional safety mechanisms that are critical for maintaining rigorous safety standards, specifically designed to comply with the Automotive Safety Integrity Level C (ASIL C) and Safety Integrity Level 2 (SIL 2) requirements. Engineers can take advantage of these microcontrollers to streamline their designs and enhance system safety without exorbitant costs.
Key Features that Ensure Safety and Reliability
Among the standout features of the AVR SD family are its dual-core lockstep CPU and dual Analog-to-Digital Converters (ADCs). Together with Error Correction Code (ECC) on all memories and a dedicated error controller module, these components significantly elevate fault detection efficiency while reducing software complexity. The microcontrollers boast rapid fault detection capabilities, achieving Fault Detection Time Intervals (FDTI) as low as 1 millisecond. This capacity is essential in protecting against hazardous situations and enhancing overall reliability.
Autonomous Error Management
Microchip's AVR SD MCUs are not just equipped with hardware safety features; they are complemented by a safety software framework that manages functional safety diagnostics. This integrated system allows the MCUs to autonomously detect and respond to errors, effectively transitioning to safe states when necessary. This capability is particularly valuable for critical functions such as thermal runaway detection or managing key sensor data with minimal power consumption.
Expanding Applications Across Industries
The versatility of AVR SD microcontrollers makes them suitable for a wide range of applications across various sectors. Safety standards compliance is vital, as these microcontrollers are designed in accordance with ISO 26262 and IEC 61508 standards, facilitating their use in aerospace, automotive, medical, and industrial automation fields. Specific implementations can be found in flight control systems, ignition controls, robotics safety features, and Advanced Driver Assistance Systems (ADAS).
Efficient Development Tools
To help engineers maximize the potential of the AVR SD MCUs, Microchip provides a suite of development tools. Compatible with TÜV SÜD functional safety certified software and popular platforms like the MPLAB® XC8 Pro compiler and Curiosity Nano development board, these tools and resources offer comprehensive safety documentation, diagnostic analysis reports, and compliance certifications that simplify the development process.
Cost and Availability
The AVR SD MCUs are competitively priced, starting at just $0.93 for orders of 5,000 units or more, with lower pricing available for larger quantities. Interested engineers and developers can connect with Microchip sales representatives or authorized distributors to explore purchasing options. Comprehensive details can also be accessed through Microchip’s Purchasing and Client Services website.
