ATTINY816-MZT-VAO

Overview

The ATTINY816-MZT-VAO is an 8-bit AVR microcontroller from Microchip Technology, belonging to the tinyAVR 1-Series family. It features a maximum clock frequency of 16 MHz and includes 16 KB of Flash program memory, 2 KB of SRAM, and 256 B of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an extended industrial temperature range from -40°C to +105°C. It is housed in a 20-VQFN package with wettable flanks, designed for automotive applications under AEC-Q100 qualification.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Wettable flank packaging for enhanced inspection capability
• Integrated Core Independent Peripherals for low-power efficiency

Applications

• Automotive electronic control units requiring functional safety
• Industrial sensor nodes operating in extended temperature environments
• Battery-powered devices utilizing low-power operational modes

Procurement Notes

Verify the suffix 'VAO' indicates AEC-Q100 automotive qualification and wettable flank construction. Confirm the specific tape and reel quantity matches production requirements. Ensure the ordering part number aligns with the required package type and temperature grade. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when automotive certification and visual solder joint inspection are mandatory. The 16 KB Flash and 2 KB SRAM provide sufficient resources for complex logic while maintaining a compact footprint. Consider the 16 MHz performance limit against system timing requirements. Evaluate the 20-VQFN package constraints regarding thermal dissipation and PCB layout density.

Part Context

This part belongs to the tinyAVR 1-Series, which integrates Core Independent Peripherals to offload tasks from the CPU. The series emphasizes low power consumption and high integration in small packages. The VAO suffix specifically denotes automotive-grade manufacturing with wettable flanks for automated optical inspection.

Replacement Considerations

Direct substitutes include other parts within the tinyAVR 1-Series with matching memory sizes and automotive qualifications. Verify package dimensions and pin assignments before substitution. Non-automotive equivalents lack the required reliability certifications.
