Overview
The ATTINY826-XU 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 utilizes a TSSOP or SSOP package (indicated by the 'X' suffix) and supports an industrial temperature range of -40°C to +85°C.
Feature Summary
- High-performance low-power AVR CPU with hardware multiplier
- Integrated Event System for peripheral signaling
- 12-bit differential ADC with Programmable Gain Amplifier
- Configurable Custom Logic with Look-Up Tables
Applications
- Industrial control systems
- Sensor nodes
- Battery-powered devices
- General-purpose embedded applications
Procurement Notes
Verify the specific package variant (TSSOP or SSOP) associated with the 'X' suffix against the manufacturer's current catalog, as this designation may encompass multiple physical form factors. Confirm that the required speed grade aligns with the intended operating voltage and temperature conditions. Ensure the ordering suffix matches the exact pin count and thermal specifications required for the design.
Selection Notes
Select this component for designs requiring vertical migration within the tinyAVR® 2 family without code modification. Consider the 20-pin configuration for balanced I/O availability. Evaluate the 12-bit ADC and CCL features if complex signal processing or logic replacement is needed. Verify compatibility with existing UPDI programming tools.
Part Context
This part belongs to the ATtiny82x series within the tinyAVR® 2 family, sharing architecture with ATtiny426 and ATtiny827 variants. It offers enhanced analog peripherals compared to previous generations, including a PGA-enabled ADC. The device maintains pin and feature compatibility across the family for scalable development.
Replacement Considerations
Direct substitutes include other members of the tinyAVR® 2 family such as ATtiny426-XU or ATtiny827-XU, provided pin counts and memory requirements are met. Cross-family replacements require careful review of instruction set differences and peripheral configurations.
