ATTINY827-MU

Overview

The ATTINY827-MU is an 8-bit AVR microcontroller from the tinyAVR 2 family, featuring a 20-pin VQFN package. It operates at up to 20 MHz with 8 KB Flash, 1 KB SRAM, and 128 B EEPROM. The device includes a 12-bit ADC with PGA, two USARTs, SPI, TWI, and UPDI. It supports industrial temperature range (-40°C to +85°C) and runs on 1.8V to 5.5V.

Feature Summary

• Features a high-performance low-power AVR CPU with hardware multiplier and single-cycle I/O access.
• Includes advanced peripherals such as a 12-bit differential ADC with Programmable Gain Amplifier (PGA) and Configurable Custom Logic (CCL).
• Supports flexible clock options including internal oscillators and external crystal inputs for precise timing control.
• Provides multiple sleep modes like Idle, Standby, and Power-Down to optimize power consumption.

Applications

• Real-time control systems requiring low power consumption.
• Industrial applications needing robust peripheral interfaces.
• Battery-powered devices utilizing efficient sleep modes.

Procurement Notes

Verify the specific ordering suffix 'MU' corresponds to the 20-pin VQFN package and industrial temperature range. Confirm availability status as distribution channels may vary. Ensure compatibility with existing design constraints regarding pin count and memory size before procurement.

Selection Notes

Select this component for designs requiring vertical migration within the tinyAVR 2 family without code modification. Consider the 20-pin variant if more I/O or features are needed compared to the 14-pin version. Evaluate the 12-bit ADC and CCL capabilities against application requirements for signal processing and logic implementation.

Part Context

Part of the tinyAVR 2 family, offering pin and feature compatibility across variants. Designed for scalable development from smaller to larger packages within the same series. Supports horizontal migration to reduce pin counts while maintaining core functionality.

Replacement Considerations

Compatible with other ATtiny82x variants in the tinyAVR 2 family for vertical migration. Check datasheet for specific differences in SRAM/EEPROM sizes when selecting alternatives like ATtiny826 or ATtiny824.
