ATTINY461-15MZ

Overview

The ATTINY461-15MZ is an automotive-grade 8-bit AVR microcontroller featuring 4K bytes of in-system programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates at speeds up to 16MHz within the 4.5V to 5.5V supply range and supports 0-8MHz operation down to 2.7V. The device includes a 10-bit ADC with 11 single-ended channels, multiple timers, and a Universal Serial Interface. It utilizes a 32-pad MLF package and complies with AEC-Q100 Grade 1 standards for extended temperature ranges.

Feature Summary

Automotive-grade reliability verified under AEC-Q100 Grade 1 standards
Advanced RISC architecture enabling high throughput per MHz
In-system programmable non-volatile memory with high endurance
Integrated analog-to-digital converter with differential channel support

Applications

Automotive electronic control units
Sensor interface modules
Low-power embedded systems requiring extended temperature stability

Procurement Notes

Verify that the specific suffix 'MZ' corresponds to the 32-pad MLF package variant. Confirm the speed grade matches the required operating voltage and frequency constraints for your application environment. Ensure compatibility with the specified automotive temperature range during component selection.

Selection Notes

Select this model when automotive qualification is mandatory. The 15MHz speed rating indicates optimized performance at higher voltages. Consider the MLF package requirements for PCB layout and thermal management compared to SOIC or TSSOP alternatives within the same family.

Part Context

This component belongs to the ATtiny261/461/861 Automotive series manufactured by Microchip Technology (formerly Atmel). It shares the core AVR CPU architecture with other members but is distinguished by its specific memory size, package type, and automotive certification compliance.
