ATTINY26L-8MUR

Overview

The ATTINY26L-8MUR is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 2K bytes of in-system programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of SRAM. The device operates at a maximum clock frequency of 8 MHz with a supply voltage range of 2.7V to 5.5V. It includes a 10-bit ADC with 11 single-ended channels, two 8-bit Timer/Counters, and a Universal Serial Interface. The component is housed in a 32-lead QFN/MLF package and supports industrial operating temperatures from -40°C to +85°C.

Feature Summary

• High-performance 8-bit AVR core executing most instructions in a single clock cycle
• Integrated 10-bit Analog-to-Digital Converter with differential input gain stages
• Dual 8-bit Timer/Counter modules with high-frequency PWM outputs
• Universal Serial Interface supporting TWI or SM-bus software implementation

Applications

• Battery charger systems
• Lighting ballast applications
• Low-end thermostats
• Fire detectors

Procurement Notes

Verify that the ordering suffix 'R' corresponds to tape and reel packaging as specified in the official documentation. Confirm the specific speed grade (8 MHz) and industrial temperature range (-40°C to +85°C) match the project requirements. Ensure the 32-lead QFN/MLF package dimensions align with the PCB footprint design before finalizing procurement.

Selection Notes

Select this model for designs requiring low power consumption within the 2.7V to 5.5V range. The 8 MHz speed grade is suitable for cost-sensitive embedded control applications where processing throughput approaching 1 MIPS per MHz is sufficient. Consider the 32-lead QFN/MLF package if surface mount space constraints are critical compared to the 20-lead alternatives.

Part Context

This component belongs to the ATtiny26(L) family of 8-bit microcontrollers. It shares the same core architecture and peripheral set as the ATtiny26 but offers a lower minimum operating voltage of 2.7V compared to the standard ATtiny26's 4.5V. The 'L' designation indicates the low-voltage variant optimized for extended battery life applications.

Replacement Considerations

ATtiny26L-8MU is the lead-free PDIP/SOIC equivalent. ATtiny26-16MUR is a higher-speed variant requiring 4.5V minimum voltage.
