ATTINY261-15MAZ

Overview

The ATTINY261-15MAZ is an automotive-grade 8-bit AVR microcontroller featuring 2K bytes of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. It operates within a voltage range of 2.7V to 5.5V and supports clock speeds up to 8MHz at the minimum voltage or 16MHz between 4.5V and 5.5V. The device includes a 10-bit ADC with 11 single-ended channels, three high-frequency PWM outputs, and a Universal Serial Interface. It utilizes a 32-VQFN package and functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Automotive-grade reliability verified per AEC-Q100 Grade 1 standards
• Advanced RISC architecture achieving near 1MIPS per MHz throughput
• Integrated 10-bit analog-to-digital converter with differential inputs
• In-system programmable via SPI interface for flash and EEPROM

Applications

• Automotive sensor interfaces
• Body control modules
• Low-power embedded systems requiring extended temperature operation

Procurement Notes

Verify that the specific suffix 'MAZ' corresponds to the required automotive qualification and package configuration. Confirm the operating voltage and speed grade requirements align with the 2.7V to 5.5V specification. Ensure the design accounts for the 32-pad MLF/QFN thermal pad grounding requirements specified in the datasheet.

Selection Notes

Select this component when automotive certification (AEC-Q100) is mandatory. Choose this part over non-automotive variants if the application demands operation up to +125°C. Consider the 2KB Flash limit for code size and the 16MHz maximum speed at higher voltages during system planning.

Part Context

This device belongs to the ATtiny261/461/861 family of 8-bit AVR microcontrollers designed for automotive environments. It shares architectural similarities with standard AVR cores but adheres to stricter manufacturing quality standards under ISO-TS 16949. The 'Z' identifier denotes the full automotive temperature range capability.
