Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct factory channels. Confirm datasheet revision 1187H matches the physical marking. Check for RoHS compliance documentation. Note that this specific model may be discontinued; validate current availability status before finalizing procurement plans.

Selection Notes

Select this component for designs requiring minimal pin count and low power consumption. Ensure the application voltage stays within the 2.7V to 5.5V range. Consider the limited I/O count and memory size when defining system requirements. Verify that the 8-lead PDIP package fits the target PCB layout constraints.

Part Context

This device belongs to the ATtiny family of 8-bit microcontrollers manufactured by Microchip Technology. It utilizes the AVR core architecture known for efficiency and code density. The L suffix typically denotes a low-voltage variant optimized for lower power operation compared to standard versions within the same series.

Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully. Ensure any replacement maintains compatibility with existing firmware and hardware interfaces.
