ATTINY26L-8PI

Overview

The ATTINY26L-8PI is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features a 20-lead PDIP package and operates within an industrial temperature range of -40°C to +85°C. The device provides 2K bytes of in-system programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of internal SRAM. It supports a maximum clock frequency of 8 MHz with a supply voltage range of 2.7V to 5.5V.

Feature Summary

• High-performance, low-power 8-bit AVR architecture with up to 1 MIPS throughput at 1 MHz
• Rich peripheral set including a 10-bit ADC with 11 single-ended channels and differential inputs
• Two 8-bit Timer/Counters with PWM outputs and a Universal Serial Interface (USI)
• Multiple power-saving modes including Idle, Noise Reduction, and Power-down

Applications

• Battery chargers
• Lighting ballasts
• Low-end thermostats
• Fire detectors

Procurement Notes

Verify that the ordering code matches the specific speed grade and package configuration required for the design. Confirm the operational temperature range aligns with environmental specifications. Ensure compatibility with existing development tools and programming interfaces before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring low power consumption and moderate processing capabilities. The 8 MHz speed grade is suitable for systems where energy efficiency is prioritized over high-speed execution. Consider the available I/O lines and ADC channels against interface requirements.

Part Context

This part belongs to the ATtiny26(L) family of microcontrollers. It shares architectural similarities with the standard ATtiny26 but offers extended low-voltage operation down to 2.7V. The 'L' suffix indicates the low-voltage variant, while '8' denotes the 8 MHz speed grade.

Replacement Considerations

Direct substitutes include other ATtiny26L variants with different packages or speed grades, such as ATTINY26L-8SU or ATTINY26L-8PU. Cross-family replacements from other manufacturers require careful evaluation of pin compatibility and instruction set differences.
