Overview
The AVR32SD32-I/QZB is an 8-bit microcontroller from the AVR SD series, featuring a dual-core lockstep CPU architecture for functional safety compliance. It integrates 32KB of system-in-programmable Flash with ECC, 4KB of SRAM with ECC, and 256 bytes of EEPROM with ECC. The device supports clock speeds up to 20MHz and operates within a voltage range of 2.7V to 5.5V. It includes multiple peripherals such as USART, SPI, TWI, ADC, and comparators, housed in a QFN package.
Feature Summary
- Dual-core lockstep CPU configuration ensures high reliability and meets ISO 26262 (ASIL C) and IEC 61508 (SIL 2) standards.
- Integrated error correction codes (ECC) on Flash, SRAM, and EEPROM provide single-error correction and double-error detection capabilities.
- Programmable Debug Interface Disable (PDID) enhances security by preventing unauthorized access to programming and debugging interfaces.
Applications
- Automotive systems requiring functional safety certification
- Industrial automation controllers
- Medical devices
- Security systems
Procurement Notes
Verify the specific suffix 'QZB' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with MPLAB X IDE and UPDI programming tools. Check for availability of development kits like Curiosity Nano for prototyping. Confirm RoHS compliance and lead times through authorized distributors.
Selection Notes
Select this component when functional safety integrity levels ASIL C or SIL 2 are required. The dual-core architecture and ECC memory make it suitable for critical applications where data integrity and fault tolerance are paramount. Consider pin count and peripheral requirements relative to other variants in the AVR32SD family.
Part Context
The AVR32SD series represents Microchip's entry into safety-certified 8-bit microcontrollers. Combining standard AVR performance with hardware-based safety features, these MCUs bridge the gap between general-purpose embedded control and safety-critical applications. The series supports flexible low-power architectures and advanced digital peripherals.
Replacement Considerations
AVR32SD20-I/QZB: Lower pin count variant. AVR32SD28-I/QZB: Different package and peripheral set. Verify pin compatibility and memory size differences before substitution.
