ATTINY417-MZT-VAO

Overview

The ATTINY417-MZT-VAO is an automotive-grade microcontroller from the tinyAVR® 1-series, manufactured by Microchip Technology. It features an 8-bit AVR CPU with a hardware multiplier, operating at speeds up to 16 MHz. The device includes 4 KB of in-system self-programmable Flash memory, 256 bytes of SRAM, and 128 bytes of EEPROM. It is housed in a 20-pin VQFN package with wettable flanks, designed for surface mount installation.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Integrated capacitive touch interface via the Peripheral Touch Controller (PTC) supporting buttons, sliders, and wheels.
• Supports low-power operation through multiple sleep modes including Idle, Standby, and Power-Down with full data retention.
• Includes Core Independent Peripherals such as Event System and SleepWalking for efficient background task handling.

Applications

• Automotive body electronics and control modules
• In-cabin user interface and touch sensing applications
• Low-power sensor nodes requiring event-driven wake-up
• Industrial control systems with functional safety requirements

Procurement Notes

Verify that the specific suffix MZT-VAO corresponds to the Automotive grade variant with wettable flanks and tape-and-reel packaging. Confirm the temperature range meets the application's thermal requirements, typically -40°C to 105°C or 125°C. Ensure compatibility with existing PCB footprints for the 20-pin VQFN package before finalizing procurement orders.

Selection Notes

Select this component when automotive reliability and capacitive touch integration are required within a compact form factor. The 4 KB Flash size suits applications with moderate code complexity. Consider the 20-pin VQFN package if board space is limited but wettable flank soldering benefits are needed for robustness. Evaluate power consumption profiles against the available sleep modes for battery-operated automotive subsystems.

Part Context

This part belongs to the ATtiny416/417/814/816/817 Automotive series, which extends the standard tinyAVR 1-series capabilities to meet automotive quality standards. It shares architectural similarities with non-automotive variants but includes enhanced testing and documentation for automotive deployment. The series emphasizes low power and peripheral richness in small packages.

Replacement Considerations

Direct replacements include other parts from the ATtiny416/417/814/816/817 Automotive family with compatible pinouts and memory sizes. Verify that any substitute maintains the AEC-Q100 qualification and wettable flank package option if required for manufacturing processes.
