Overview
The AVR32SD20-E/SS is an 8-bit microcontroller from Microchip Technology, featuring the AVR core with a maximum clock frequency of 20 MHz. It includes 32 kB of system-in-programmable flash memory with ECC, 4 kB of SRAM with ECC, and 256 B of EEPROM. The device operates within a voltage range of 2.7 V to 5.5 V and supports temperatures from -40°C to +125°C. It is housed in a 20-pin SSOP package and provides 15 I/O pins. Key peripherals include two ADCs, three comparators, two zero-crossing detectors, two watchdog timers, three USARTs, two SPI interfaces, and two TWI interfaces.
Feature Summary
- Dual-core lockstep CPU configuration for enhanced functional safety
- Single-cycle I/O access and dual-cycle hardware multiplier for efficient processing
- Integrated error controller and SECDED ECC for program memory, SRAM, and EEPROM
- Programmable Debug Interface Disable (PDID) for secure programming and debugging
Applications
- Automotive safety systems compliant with ISO 26262 ASIL C
- Industrial automation requiring high reliability
- Medical devices adhering to IEC 61508 SIL 2 standards
- Consumer electronics demanding robust security features
Procurement Notes
Verify component authenticity through authorized Microchip distributors or direct factory channels. Confirm the specific suffix matches the required package and temperature grade. Check current availability status as supply constraints may affect lead times. Ensure compliance with RoHS directives and relevant regional regulations before integration into final products.
Selection Notes
Select this model when dual-core lockstep architecture and functional safety certifications are mandatory. Consider the 20 MHz speed and 32 kB memory capacity against application requirements. Evaluate the 2.7 V to 5.5 V operating range for power supply compatibility. Compare peripheral counts, such as the number of USARTs and ADCs, with other variants in the AVR32SD series.
Part Context
This component belongs to the AVR32SD family, designed for applications requiring high reliability and safety integrity levels. The series integrates advanced security features like PDID and comprehensive error checking mechanisms. It targets markets where deterministic performance and fault tolerance are critical, distinguishing it from standard consumer-grade microcontrollers.
Replacement Considerations
Consult official Microchip documentation for pin-compatible or functionally equivalent alternatives within the AVR32SD series. Verify that any substitute maintains the required safety certifications and memory specifications.
