ATTINY25-15SZ

Overview

The ATtiny25-15SZ is an automotive-grade 8-bit AVR microcontroller featuring 2 KB of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates within a voltage range of 2.7 V to 5.5 V and supports clock frequencies up to 16 MHz at the upper voltage limit. The device utilizes a high-performance RISC architecture with 32 general-purpose working registers and executes most instructions in a single clock cycle. It includes six programmable I/O lines, a 10-bit ADC, and multiple timer/counters.

Feature Summary

• Automotive quality grade compliant with ISO-TS-16949 and AEC-Q100 standards
• Extended temperature operation capability reaching +125°C
• Single-cycle execution for enhanced processing efficiency
• Integrated non-volatile memory with high endurance ratings

Applications

• Automotive embedded control systems
• Industrial monitoring devices requiring extended temperature stability
• Consumer electronics utilizing automotive-grade reliability

Procurement Notes

Verify that the ordering suffix 'Z' corresponds to the full automotive temperature range (-40°C to +125°C). Confirm package type matches project requirements. Ensure supply chain sources provide valid traceability documentation for automotive qualification standards.

Selection Notes

Select this component when automotive reliability and extended temperature performance are mandatory. The 2 KB Flash capacity suits applications with moderate code size requirements. Verify that the 16 MHz speed grade meets timing constraints at the target operating voltage.

Part Context

This part belongs to the ATtiny25/45/85 Automotive family manufactured by Microchip Technology. It shares the core AVR architecture with other variants but is distinguished by its specific temperature rating and package configuration suitable for harsh environments.

Replacement Considerations

Direct substitutes include ATtiny45-15SZ and ATtiny85-15SZ for increased memory. Industrial grade equivalents like ATtiny25-15SU lack the extended temperature and automotive certification.
