ATTINY806-SF

Overview

The ATtiny806-SF is an 8-bit AVR microcontroller from the tinyAVR 0-series, featuring 8 KB of in-system self-programmable Flash memory, 512 bytes of SRAM, and 128 bytes of EEPROM. It operates at clock speeds up to 20 MHz with a supply voltage range of 1.8V to 5.5V. The device utilizes a 20-pin VQFN (3x3 mm) package and supports industrial temperature ranges of -40°C to 105°C or -40°C to 125°C.

Feature Summary

• Integrates a high-performance 8-bit AVR CPU with a two-cycle hardware multiplier and single-cycle I/O access for efficient instruction execution.
• Includes Core Independent Peripherals such as a Real-Time Counter (RTC), Configurable Custom Logic (CCL), and an automated CRC memory scan system.
• Features a flexible Event System that enables direct inter-peripheral signaling without CPU intervention, reducing power consumption and latency.

Applications

• Low-power sensor nodes requiring periodic data acquisition and processing
• Battery-operated devices utilizing ultra-low-power sleep modes
• Industrial control systems needing reliable watchdog timers and brown-out detection

Procurement Notes

Verify the specific speed grade suffix required for your operating voltage and frequency constraints. Confirm the package type matches the PCB footprint requirements. Ensure the selected variant meets the necessary industrial temperature specifications for the intended deployment environment.

Selection Notes

Select this component when a balance of moderate program memory and advanced analog peripherals is needed within a compact form factor. Consider the availability of multiple voltage references and the event system for applications requiring precise timing and low-latency signal routing between sensors and actuators.

Part Context

This part belongs to the tinyAVR 0-series family, designed for cost-sensitive embedded applications. It shares architectural similarities with the ATtiny804 and ATtiny807 but offers distinct pin counts and peripheral configurations suitable for space-constrained designs requiring robust non-volatile memory endurance.

Replacement Considerations

Direct substitutes include other members of the tinyAVR 0-series such as the ATtiny804 or ATtiny807, provided pin compatibility and memory sizes align with the design requirements. Verify that alternative packages maintain the same thermal and electrical characteristics.
