ATTINY461-15XD

Overview

The ATTINY461-15XD 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 a maximum frequency of 15MHz within the 2.7V to 5.5V supply range. The device includes a 10-bit ADC with 11 single-ended channels, three high-frequency PWM outputs, and debugWIRE support. It is designed for -40°C to +125°C operation.

Feature Summary

• Automotive-grade reliability verified per AEC-Q100 standards
• Advanced RISC architecture enabling single-cycle instruction execution
• Integrated non-volatile memory with high endurance ratings
• Comprehensive peripheral set including timers, ADC, and analog comparator

Applications

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

Procurement Notes

Verify that the specific suffix '15XD' corresponds to the requested speed grade and package configuration. Confirm the component meets the required automotive qualification standards and temperature range specifications before integration into production designs.

Selection Notes

Select this model when automotive certification is mandatory and extended temperature operation is required. Ensure the design utilizes the 2.7V to 5.5V operating voltage window and accommodates the 15MHz maximum clock speed constraints for the target application environment.

Part Context

This component belongs to the ATtiny261/461/861 family of automotive microcontrollers manufactured by Microchip Technology (formerly Atmel). It shares architectural similarities with standard commercial variants but adheres to stricter quality and reliability protocols defined by international automotive industry standards.

Replacement Considerations

Cross-reference with other ATtiny461 variants such as ATTINY461A or ATTINY461-PU only if automotive qualification and the specific 15MHz speed grade are not critical requirements.
