ATTINY26L-8SUR

Overview

The ATTINY26L-8SUR is an 8-bit AVR microcontroller featuring a 2K byte Flash program memory, 128 bytes EEPROM, and 128 bytes SRAM. It operates at a maximum clock frequency of 8 MHz with a supply voltage range of 2.7V to 5.5V. The device includes 16 programmable I/O lines, an 11-channel 10-bit ADC, two 8-bit timers/counters, and a Universal Serial Interface supporting SPI and TWI protocols. It is housed in a 20-lead SOIC package.

Feature Summary

• High-performance RISC architecture executing most instructions in a single clock cycle
• Integrated high-resolution analog-to-digital converter with differential input capability
• Multiple power-saving modes including idle, noise reduction, and power-down
• 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 suffix 'SUR' corresponds to the tape and reel packaging format as indicated in official ordering tables. Confirm that the industrial temperature rating (-40°C to +85°C) aligns with the intended operational environment requirements before finalizing procurement specifications.

Selection Notes

Select this component when low power consumption is critical alongside moderate processing speed. The ATtiny26L variant supports operation down to 2.7V, making it suitable for battery-powered designs where the standard ATtiny26's higher minimum voltage would be unsuitable. Ensure the 2K Flash capacity meets application code size constraints.

Part Context

This part belongs to the ATtiny26(L) family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. It shares core functional blocks with the ATtiny26 but offers a lower operating voltage range. The series is designed for cost-effective embedded control solutions requiring non-volatile memory and analog interfacing capabilities.
