For more information visit the AVR SD Product Family page
The AVR® SD microcontroller (MCU) family is designed in compliance with the ISO 26262 and IEC 61508 safety standards.
The ASIL C (ISO 26262) and SIL 2 (IEC 61508) compliant MCU can simplify applications targeting high safety levels up to ASIL D, SIL 3 and Class C (IEC 60730), owing to advanced features like a dual-core lockstep CPU, Error Correction Code (ECC) on Flash, SRAM and EEPROM, error injection support and a dedicated error controller. These hardware safety features reduce software complexity and offer real time response for fault detection, error handling and activating safe states.
The AVR32SD28 is running at up to 20 MHz across the full supply voltage range of 2.7V to 5.5V and is available in 28-pin SPDIP, TQFP and VQFN with Wettable Flanks packages.
Program and Debug Interface Disable (PDID)
The AVR SD MCUs incorporate the PDID feature which makes it possible to 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.
