ATTINY806-SFR

Overview

The ATTINY806-SFR is an 8-bit AVR microcontroller from the tinyAVR 0-series, featuring 8 KB of Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM. It operates at speeds up to 20 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 10-bit ADC, USART, SPI, TWI, TCA, TCB, RTC, and UPDI interface. It is housed in a 20-pin SOIC package.

Feature Summary

• Features a flexible low-power architecture with Core Independent Peripherals (CIPs) for CPU offloading.
• Includes an Event System for predictable inter-peripheral signaling without CPU intervention.
• Supports single-pin programming and debugging via the Unified Program and Debug Interface (UPDI).
• Provides multiple voltage references and configurable custom logic for analog and digital applications.

Applications

• Industrial control systems requiring functional safety features.
• Battery-powered devices utilizing ultra-low power sleep modes.
• Sensor interfaces using the high-speed ADC and event system.
• Communication nodes using USART or TWI protocols.

Procurement Notes

Verify the specific suffix 'SFR' against the manufacturer's official documentation to confirm the exact package type and temperature rating. Ensure compatibility with existing design constraints regarding pinout and electrical specifications before procurement.

Selection Notes

Select this component for designs requiring a balance of processing speed and peripheral richness in a compact form factor. Consider the 20 MHz maximum frequency and available I/O lines relative to system requirements. Evaluate the 8 KB Flash capacity against application code size needs.

Part Context

This part belongs to the tinyAVR 0-series, which utilizes advanced technologies for low power consumption and enhanced peripheral integration. It shares architectural similarities with other members like the ATtiny804 and ATtiny807 but differs in memory sizes and package options.

Replacement Considerations

Check for direct substitutes within the same series such as ATtiny804 or ATtiny807 variants, ensuring pin compatibility and memory requirements are met. Verify that any replacement maintains the required operating temperature range and package dimensions.
