ATTINY817-MBT-VAO

Overview

The ATTINY817-MBT-VAO is an automotive-grade 8-bit AVR microcontroller featuring 8KB of Flash program memory and 512 bytes of RAM. It operates within a supply voltage range of 1.8V to 5.5V and supports clock frequencies up to 20MHz. The device includes a 10-bit ADC with 12 channels and an 8-bit DAC. Packaged in a 24-VQFN exposed pad, it is qualified under AEC-Q100 standards for operation between -40°C and 105°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Integrated capacitive touch sensing capabilities via QTouch library support
• High-performance 8-bit AVR core architecture

Applications

• Automotive body electronics
• Capacitive touch sensor interfaces
• General embedded control systems

Procurement Notes

Verify the specific suffix VAO confirms automotive grade (AEC-Q100) qualification and temperature range (-40°C to 105°C). Confirm package type is 24-VQFN. Ensure compatibility with required firmware libraries for QTouch functionality if applicable.

Selection Notes

Select this component for applications requiring automotive reliability and integrated touch sensing. Compare against standard commercial grades if environmental constraints are less stringent. Consider pin count and peripheral requirements such as ADC channels and communication interfaces.

Part Context

Part of the tinyAVR-1 family, designed for cost-sensitive embedded applications. Offers enhanced features compared to previous generations, including improved analog performance and touch sensing integration. Suitable for replacing legacy 8-bit MCUs in modern designs.

Replacement Considerations

Check pin-to-pin compatibility with ATTINY816 or ATTINY814 variants. Verify software migration efforts for register-level differences. Ensure alternative components meet the same AEC-Q100 automotive qualification requirements.
