ATTINY15L-1PI

Overview

The ATtiny15L-1PI is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture, manufactured by Atmel. It features 1K bytes of In-System Programmable Flash with an endurance of 1,000 write/erase cycles and 64 bytes of In-System Programmable EEPROM with 100,000 cycle endurance. The device includes 32 general-purpose working registers and operates at speeds up to 1 MIPS per MHz. It supports a supply voltage range of 2.7V to 6.0V and offers multiple low-power modes including Idle and Power Down. The unit is housed in an 8-pin PDIP package.

Procurement Notes

Verify the specific suffix 'L' indicates the low-voltage variant (2.7V–6.0V) compared to standard versions. Confirm the 'P' suffix denotes the PDIP package type required for through-hole mounting. Check manufacturer status as legacy components may have limited availability or obsolescence notices. Ensure compatibility with existing 8-pin DIP footprints during procurement planning.

Selection Notes

Select this component when a balance of low cost, small physical size, and sufficient processing power for simple tasks is required. The low-voltage specification makes it suitable for battery-operated devices where energy efficiency is critical. Consider the limited memory resources for complex applications requiring extensive data logging or advanced algorithms.

Part Context

This part belongs to the ATtiny family of 8-bit AVR microcontrollers designed for resource-constrained embedded applications. It shares architectural similarities with other ATtiny models but distinguishes itself through its specific memory configuration and low-voltage operational capabilities. The series is known for enabling designers to optimize power consumption against processing speed effectively.

Replacement Considerations

Direct substitutes include other ATtiny15 variants such as ATTINY15-10PU, provided the voltage and speed requirements align. Verify pinout compatibility and software register mapping before swapping to ensure seamless integration without hardware redesign.
