AVR32SD32-E/QZB

Overview

The AVR32SD32-E/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 operation up to 20MHz with a supply voltage range of 2.7V to 5.5V. Key peripherals include multiple timers, ADCs, comparators, and communication interfaces such as USART, SPI, and TWI.

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 ports.

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 development tools like MPLAB X IDE. Confirm availability status directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when dual-core redundancy and functional safety are critical. Compare memory sizes and peripheral counts against requirements. Consider the QZB package constraints for PCB layout. Evaluate power consumption in sleep modes if battery operation is required.

Part Context

Part of the AVR SD family designed for safety-critical applications. Shares core architecture with AVR32SD20 and AVR32SD28 variants, differing primarily in memory capacity and pin count. Designed for robust performance in harsh environments.

Replacement Considerations

AVR32SD28-E/QZB offers similar features with increased memory. AVR32SD20-E/QZB provides reduced memory capacity. Verify pinout compatibility before substitution.
