ATTINY826-XFR

Overview

The ATtiny826-XFR is an 8-bit AVR microcontroller from the tinyAVR® 2 family, featuring 8 KB of Flash memory, 1 KB of SRAM, and 128 B of EEPROM. It operates at a maximum frequency of 20 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit differential ADC with PGA, two USARTs, SPI, TWI, and an Event System. It is housed in a 20-pin package (SOIC, SSOP, or VQFN) and supports industrial (-40°C to +85°C) and extended (-40°C to +125°C) temperature ranges.

Feature Summary

• High-performance low-power AVR CPU with hardware multiplier
• Advanced analog features including 12-bit differential ADC with PGA
• Flexible event system for inter-peripheral signaling
• Configurable Custom Logic (CCL) with programmable Look-Up Tables

Applications

• Sensor nodes requiring high responsiveness
• Battery-powered applications utilizing low-power sleep modes
• Industrial control systems needing robust peripheral interfaces
• Automotive applications qualified under AEC-Q100 standards

Procurement Notes

Verify the specific package type (SOIC, SSOP, or VQFN) and temperature grade (industrial or extended) required for your design, as these are determined by the ordering suffix. Confirm that the 'XFR' suffix corresponds to the Tape & Reel carrier type if automated assembly is planned. Ensure compatibility with the UPDI programming interface for development and production flashing.

Selection Notes

Select this component when vertical migration within the tinyAVR® 2 family is desired without code modification. It is suitable for designs requiring up to 18 general-purpose I/O pins and advanced analog capabilities like the 12-bit ADC with PGA. Consider the extended temperature range variant if operation beyond 85°C is necessary.

Part Context

This part belongs to the tinyAVR® 2 family, which offers pin and feature compatibility across devices with varying memory sizes. The ATtiny826 provides a balance of processing power and peripheral richness, sitting between the smaller ATtiny426 and larger ATtiny1626 in terms of memory capacity while maintaining the same 20-pin footprint options.
