ATTINY806-SN

Overview

The ATtiny806-SN 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 includes a hardware multiplier, a 10-bit ADC, multiple timers (TCA/TCB), USART, SPI, TWI, and an Event System. It supports a supply voltage range of 1.8V to 5.5V and operates within industrial temperature ranges (-40°C to 105°C or -40°C to 125°C). The component is housed in a 20-pin SOIC package.

Feature Summary

• Features a flexible low-power architecture with Core Independent Peripherals (CIPs) and an Event System for CPU-independent signaling.
• Includes accurate analog capabilities such as a 10-bit ADC with multiple voltage references and an Analog Comparator.
• Supports single-pin programming and debugging via the Unified Program and Debug Interface (UPDI).
• Provides Configurable Custom Logic (CCL) with programmable look-up tables for custom logic implementation.

Applications

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

Procurement Notes

Verify the specific speed grade suffix and temperature range code associated with the SN package variant against the official datasheet before procurement. Confirm that the ordering part number matches the required Flash size and package type. Ensure compatibility with UPDI programming tools. Check for any recent product change notifications regarding pinout or electrical characteristics.

Selection Notes

Select this component when an 8-bit AVR core with 8 KB Flash and 20-pin SOIC packaging is required. Consider the tinyAVR 0-series architecture for applications needing precise analog features and low power efficiency. Evaluate the available peripherals like TCA, TCB, and RTC against project requirements. Compare against other members of the ATtiny804/806/807 family based on memory size and I/O count.

Part Context

The ATtiny806 belongs to the tinyAVR 0-series, which utilizes advanced Microchip technology for low power and flexibility. This series integrates Core Independent Peripherals to offload tasks from the CPU. The 0-series is designed for cost-sensitive applications while maintaining high performance through the AVR RISC architecture running at up to 20 MHz.

Replacement Considerations

Check for direct substitutes within the ATtiny804/806/807 family based on memory and package differences. Verify pin-to-pin compatibility if replacing with other 20-pin SOIC MCUs. Consult the datasheet for any silicon errata or design-in notes affecting equivalent components.
