Procurement Notes

Verify the specific ordering code ATtiny87-A15XD against the manufacturer's current Automotive Microcontrollers datasheet (Document 7792D). Confirm that the package type corresponds to the 6G thin shrink small outline package variant. Ensure procurement channels provide documentation confirming AEC-Q100 Grade 0 qualification status for the intended application environment.

Selection Notes

Select this component when applications require robust performance in extreme thermal conditions exceeding standard industrial limits. The device is suitable for designs needing integrated LIN bus capabilities alongside standard peripheral interfaces. Consider the 16MHz maximum clock speed and 16KB program memory capacity relative to firmware requirements. Verify voltage compatibility with the specified 4.5V to 5.5V operational range.

Part Context

This part belongs to the ATtiny87/ATtiny167 family of 8-bit AVR microcontrollers manufactured by Microchip Technology (formerly Atmel). The 'A' suffix denotes automotive grade qualification, while '15' indicates the 16MHz speed bin and 5V operation. The 'XD' suffix identifies the specific 6G TSSOP package configuration.

Replacement Considerations

Consult the official appendix datasheet for direct cross-references. Potential substitutes include other members of the ATtiny87/ATtiny167 automotive series, such as the ATtiny167-A15XD, provided memory size differences are acceptable. Verify pinout and electrical characteristics match before substitution.
