Overview
The AVR32SD32-I/PT is an 8-bit microcontroller from the AVR SD series, featuring a 32 kB flash memory with ECC and 4 kB SRAM. It operates at a maximum clock frequency of 20 MHz within a TQFP-32 package. The device supports a supply voltage range of 2.7 V to 5.5 V and includes a 12-bit ADC, three comparators, zero-crossing detectors, a DAC, and multiple communication interfaces including USART, SPI, and TWI.
Feature Summary
- Dual-core lockstep CPU configuration for functional safety compliance
- Hardware error correction codes (ECC) for flash, SRAM, and EEPROM
- Integrated event system for predictable peripheral signal transmission
- Advanced digital peripherals including configurable logic blocks
Applications
- Automotive safety systems
- Industrial automation controllers
- Medical devices
- Consumer electronics requiring high reliability
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with development tools such as MPLAB X IDE. Confirm availability through authorized distributors as stock levels fluctuate. Check for any recent lifecycle notices or obsolescence warnings before finalizing procurement plans.
Selection Notes
Select this component when ISO 26262 ASIL C or IEC 61508 SIL 2 compliance is required. The dual-core architecture and ECC features make it suitable for safety-critical applications. Consider the 20 MHz performance limit and available I/O count relative to system requirements. Evaluate the integrated analog peripherals if signal conditioning is needed without external components.
Part Context
This part belongs to the AVR SD family, designed for robust embedded control. It combines standard AVR architecture with enhanced safety features like lockstep processing and memory protection. The series targets markets demanding high reliability and deterministic behavior in compact packages.
Replacement Considerations
Check for direct pin-compatible substitutes within the AVR SD series, such as variants with different memory sizes or package options. Verify that any replacement maintains the same safety certification level and core functionality.
