ATTINY817-MZT-VAO

Overview

The ATTINY817-MZT-VAO is an automotive-grade 8-bit AVR microcontroller featuring a hardware multiplier running at up to 20MHz. It integrates 8KB of Flash memory, 512B of SRAM, and 128B of EEPROM within a VQFN-20 package. The device supports a supply voltage range from 1.8V to 5.5V and operates across an industrial temperature range extending to 125°C. Key peripherals include a 10-bit ADC, 22 I/O lines, and Core Independent Peripherals such as the Event System and QTouch controller for capacitive touch interfaces.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
• Integrated wettable flanks on the VQFN-20 package to enhance solder joint inspection and mechanical stability
• Supports low-power operation through advanced power management features and multiple sleep modes

Applications

• Automotive body control modules requiring robust MCU performance
• Industrial sensor nodes utilizing capacitive touch interfaces
• Battery-powered devices necessitating extended operational life

Procurement Notes

Verify that the specific suffix -MZT-VAO corresponds to the automotive grade (AEC-Q100) and wettable flank package variant. Confirm the tape and reel quantity matches production requirements. Ensure the operating temperature range meets the specific environmental constraints of the target application before finalizing procurement.

Selection Notes

Select this component when automotive certification is mandatory for the project. The wettable flank feature simplifies automated optical inspection during assembly. Consider the 20MHz clock speed and peripheral set against power consumption limits. Verify compatibility with existing development tools like Atmel Studio for programming and debugging needs.

Part Context
