ATTINY26L-8SI

Overview

The ATTINY26L-8SI is an 8-bit AVR microcontroller featuring a 2K byte Flash program memory, 128 bytes EEPROM, and 128 bytes SRAM. It operates at speeds up to 8 MHz with a supply voltage range of 2.7V to 5.5V. The device includes an 11-channel 10-bit ADC, two 8-bit timers, and a Universal Serial Interface. It utilizes a 20-lead SOIC package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• High-performance RISC architecture executing most instructions in a single clock cycle
• Integrated high-precision analog-to-digital converter with differential input gain stages
• Low-power operation with multiple sleep modes including power-down and idle
• In-system programmable via SPI port for flexible firmware updates

Applications

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

Procurement Notes

Verify the specific ordering suffix 'SI' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 20-lead SOIC format. Confirm that the industrial temperature rating meets environmental requirements. Validate programming interface support for In-System Programming via SPI.

Selection Notes

Select this component when low power consumption is critical alongside moderate processing speed. The ATtiny26L variant is suitable for designs requiring operation down to 2.7V. Consider the integrated ADC channels if analog signal acquisition is necessary without external components. Evaluate the 2K Flash capacity against application code size requirements.

Part Context

This part belongs to the ATtiny26(L) family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. The 'L' designation indicates the low-voltage version capable of operating at lower supply voltages compared to the standard ATtiny26. The series provides a cost-effective solution for embedded control applications requiring non-volatile memory and analog peripherals.
