ATTINY826-MU

Overview

The ATtiny826-MU is an 8-bit microcontroller from the Microchip tinyAVR® 2 family, utilizing the AVR CPU with a hardware multiplier. It features 8 KB of in-system self-programmable Flash memory, 1 KB of SRAM, and 128 bytes of EEPROM. The device supports a maximum clock frequency of 20 MHz and operates within a supply voltage range of 1.8V to 5.5V. It includes a 12-bit differential ADC with a Programmable Gain Amplifier (PGA), up to 15 input channels, and two USARTs. The component is housed in a 20-pin package and supports industrial temperature ranges.

Feature Summary

• Features a high-performance low-power AVR CPU running at up to 20 MHz with single-cycle I/O access and a two-cycle hardware multiplier.
• Includes an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL) with four programmable Look-Up Tables.
• Integrates a 12-bit differential Analog-to-Digital Converter (ADC) with a Programmable Gain Amplifier (PGA) and multiple internal voltage references.
• Supports vertical migration without code modification across the tinyAVR® 2 family due to full pin and feature compatibility.

Applications

• Embedded systems requiring flexible peripheral integration and low-power operation
• Applications needing precise analog signal processing with differential ADC capabilities
• Industrial control environments operating within specified temperature ranges

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with existing design constraints regarding the 20-pin VQFN or SOIC/SSOP variants. Confirm that the selected variant meets the required speed grades for the intended operating voltage and temperature conditions.

Selection Notes

Select this component when designing systems that require vertical migration within the tinyAVR® 2 family without code changes. Consider the availability of 15 ADC input channels and dual USARTs for communication-intensive applications. Evaluate the power consumption requirements against the available sleep modes and internal oscillator options.

Part Context

This device belongs to the tinyAVR® 2 family, which shares architectural similarities with other members like the ATtiny426 and ATtiny827. The family emphasizes flexibility through event-driven architectures and advanced digital peripherals. Devices in this series are designed for applications demanding efficient code execution and robust analog performance in compact packages.

Replacement Considerations

Vertical migration within the tinyAVR® 2 family allows for code-compatible substitution between devices with different memory sizes but identical pinouts. Verify that the replacement part number matches the required Flash and SRAM capacities while maintaining the same 20-pin package configuration.
