ATTINY806-SNR

Overview

The ATtiny806-SNR is an 8-bit AVR microcontroller from the tinyAVR 0-series, operating at up to 20 MHz. It features 8 KB of in-system self-programmable Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM. The device utilizes a single-cycle hardware multiplier and supports a supply voltage range of 1.8V to 5.5V. It includes a 10-bit ADC, multiple timers (TCA/TCB), USART, SPI, TWI, and a Configurable Custom Logic (CCL). The component operates within industrial temperature ranges (-40°C to 105°C or -40°C to 125°C) and uses a 20-pin SOIC package.

Feature Summary

• Integrates a flexible low-power architecture with Core Independent Peripherals (CIPs) for CPU offloading.
• Features an Event System for predictable inter-peripheral signaling without CPU intervention.
• Includes a Single-Pin Unified Program and Debug Interface (UPDI) for simplified programming.
• Provides accurate analog capabilities with a 10-bit ADC and multiple internal voltage references.

Applications

• Industrial control systems requiring reliable operation in harsh environments
• Battery-powered devices utilizing ultra-low power sleep modes
• Sensor interfaces using the integrated event system and ADC
• Communication nodes employing USART, SPI, or TWI protocols

Procurement Notes

Verify the specific speed grade suffix and temperature range code on the physical marking against the datasheet table to ensure compatibility with your voltage and environmental requirements. Confirm the package type matches the design footprint. Check for any recent product change notices regarding pinout or electrical characteristics updates.

Selection Notes

Select this model when 8 KB of program memory and 512 bytes of RAM are sufficient for the application logic. Consider the 20-pin SOIC package for board space constraints compared to larger packages. Ensure the required peripheral count, such as the number of available timers or communication interfaces, aligns with the system design before choosing between other series members.

Part Context

This component belongs to the tinyAVR 0-series family, which introduces advanced features like the Event System and CCL to 8-bit AVR architectures. It shares architectural similarities with the ATtiny804 and ATtiny807 but offers distinct memory sizes and I/O counts. The series emphasizes low power consumption and high performance relative to previous generations.

Replacement Considerations

Direct substitutes within the same package and pinout include the ATtiny804 and ATtiny807, provided memory requirements are met. Verify that the replacement part's speed grade and temperature rating match the original specifications. Cross-referencing with the ATtiny1606 may be necessary if additional memory is acceptable.
