AVR32SD32-I/PT

AVR32SD32-I/PT is an ASIL C & SIL 2 compliant dual core MCU for functional safety applications. This AVR® SD Family microcontroller, designed in compliance with the ISO 26262 functional safety standard, incorporates the AVR® CPU with a hardware multiplier running at clock speeds up to 20MHz. The family uses our latest technologies, with a flexible and low-power architecture, including an Event System, accurate analogue features, and advanced digital peripherals. The AVR® SD provides a dual-core lockstep CPU, Single-Error Correcting and Double-Error Detecting (SECDED) ECC on Flash, EEPROM and SRAM, Error Controller for functional safety, and Program and Debug Interface Disable (PDID) for security.
