ATTINY26L-8MI

Overview

The ATTINY26L-8MI is an 8-bit microcontroller based on the AVR enhanced RISC architecture, manufactured by Microchip Technology. It features 2K bytes of in-system programmable Flash memory, 128 bytes of EEPROM, and 128 bytes of internal 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 an 8-bit Timer/Counter with separate prescaler, an 8-bit high-speed Timer, a Universal Serial Interface, and a 10-bit ADC with 11 single-ended channels. The component is housed in a 32-lead QFN/MLF package.

Feature Summary

• High-performance 8-bit AVR core executing most instructions in a single clock cycle
• Integrated non-volatile memory including Flash, EEPROM, and SRAM
• On-chip analog-to-digital converter with differential input gain stages
• Multiple power-saving modes including Idle, Noise Reduction, and Power-down

Applications

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

Procurement Notes

Verify that the ordering suffix MI corresponds to the 32-lead QFN/MLF package type as specified in the official documentation. Confirm the speed grade is 8 MHz and the industrial temperature range (-40°C to +85°C) matches the design requirements. Ensure the voltage rating aligns with the 2.7V to 5.5V specification for the ATtiny26L variant.

Selection Notes

Select this component when a low-power 8-bit microcontroller with integrated ADC and multiple timer/counters is required. The ATtiny26L-8MI is suitable for designs needing up to 8 MHz processing speed within a 2.7V to 5.5V operating range. Consider the 32-lead QFN/MLF package if space constraints favor surface-mount technology over PDIP or SOIC options.

Part Context

The ATTINY26L-8MI belongs to the ATtiny26(L) family of microcontrollers from Microchip Technology. This series utilizes the AVR enhanced RISC architecture to provide efficient code execution and low power consumption. The 'L' designation indicates the low-voltage version capable of operation down to 2.7V, distinguishing it from the standard ATtiny26 which requires a minimum of 4.5V.

Replacement Considerations

Official substitutes include other variants within the ATtiny26 family such as ATTINY26L-8MU or ATTINY26-16MU, depending on package and speed requirements.
