ATTINY826-XUR

Overview

The ATtiny826-XUR is an 8-bit microcontroller from the tinyAVR® 2 family, featuring a 20 MHz AVR CPU with hardware multiplier. It provides 8 KB of Flash memory, 1 KB of SRAM, and 128 B of EEPROM. The device includes a 12-bit differential ADC with PGA, two USARTs, SPI, TWI, and an Event System. Operating voltage ranges from 1.8 V to 5.5 V, with an industrial temperature range of -40°C to +85°C.

Feature Summary

• Features a high-performance low-power AVR CPU running at up to 20 MHz with single-cycle I/O access.
• Includes advanced analog peripherals such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA).
• Supports flexible inter-peripheral signaling through a dedicated Event System.
• Offers versatile communication interfaces including dual USARTs, SPI, and TWI.

Applications

• Battery-powered consumer electronics requiring low power consumption.
• Industrial control systems utilizing robust peripheral sets.
• Smart home devices needing multiple communication protocols.
• Automotive applications compatible with standard automotive environments.

Procurement Notes

Verify the specific ordering suffix 'XUR' corresponds to the TSSOP/SSOP package type and the -40°C to +85°C temperature grade. Confirm that the 'R' suffix indicates Tape & Reel packaging if required for automated assembly. Ensure compatibility with existing design footprints before procurement.

Selection Notes

Select this component when 8 KB of program memory and 1 KB of SRAM are sufficient for the application logic. The 20-pin configuration offers a balance between pin count and feature availability. Consider the 12-bit ADC resolution and PGA for precision sensing requirements within the specified voltage and temperature ranges.

Part Context

This part belongs to the tinyAVR® 2 family, which emphasizes vertical migration capabilities without code modification. It shares architectural similarities with other members like the ATtiny426 and ATtiny827, differing primarily in memory sizes and pin counts. The family utilizes the latest Microchip technologies for efficient processing.

Replacement Considerations

ATtiny826-MU: Same core functionality but in a VQFN package instead of TSSOP/SSOP.
