ATTINY85-15SZ

Overview

The ATTINY85-15SZ is an automotive-grade, 8-bit AVR RISC microcontroller manufactured by Microchip Technology. It features 8 KB of in-system programmable Flash memory and 512 bytes of data RAM. The device operates at a maximum clock frequency of 16 MHz and supports both 3.3V and 5V supply voltages. Packaged in an 8-pin SOIC (0.209 inch width) format, it includes an internal oscillator and four 10-bit analog-to-digital converters. Certified under AEC-Q100 standards, this component is designed for high performance and energy efficiency in embedded applications requiring reliable operation within automotive environments.

Feature Summary

• Automotive-grade reliability certified to AEC-Q100 standards
• Integrated hardware multiplier for enhanced processing speed
• Compact 8-pin SOIC package suitable for space-constrained designs
• Internal oscillator eliminates need for external crystal components

Applications

• Automotive sensor interfaces
• Embedded control systems in vehicles
• Low-power consumer electronics
• Industrial monitoring devices

Procurement Notes

Verify the specific suffix 'SZ' corresponds to the automotive grade and SOIC-8 package configuration when sourcing. Confirm that the supplier provides documentation attesting to AEC-Q100 compliance, as this certification is critical for automotive integration. Ensure the voltage range matches the target application's power supply requirements before finalizing procurement.

Selection Notes

Select this component when automotive qualification is mandatory for the project. The 16 MHz speed and 8 KB flash capacity suit simple control tasks. Consider the 8-pin limitation for I/O requirements. Compare against non-automotive variants if environmental ratings are not required. Verify pin compatibility with existing PCB layouts due to the specific SOIC dimensions.

Part Context

This part belongs to the ATtiny85 family of 8-bit AVR microcontrollers. The family is known for low cost and power efficiency. The ATTINY85-15SZ specifically denotes the automotive-qualified version with a 15 MHz max operating frequency rating and SOIC packaging. It shares core architecture with other ATtiny85 variants but differs in reliability testing and temperature ranges.

Replacement Considerations

Check for ATTINY85-15SU or ATTINY85-15SSU for alternative automotive packages. Non-automotive equivalents like ATtiny85-PU lack AEC-Q100 certification. Ensure substitute parts match the 8KB Flash and 512B RAM specifications. Verify voltage and interface compatibility before substitution.
