ATTINY25-15MT1

Overview

The ATtiny25-15MT1 is an automotive-grade 8-bit AVR microcontroller featuring a high-performance RISC core. It integrates 2 Kbytes of in-system programmable Flash, 128 bytes of EEPROM, and 128 bytes of SRAM. The device supports a maximum clock frequency of 15 MHz at operating voltages between 2.7 V and 5.5 V. It includes six programmable I/O lines, a 10-bit ADC with four single-ended channels, two PWM channels, and a universal serial interface. The component operates within the -40°C to +125°C temperature range and utilizes a 20-pin QFN package.

Feature Summary

• Automotive quality grade verified per AEC-Q100 standards for reliability
• Enhanced RISC architecture enabling single-cycle instruction execution
• Integrated non-volatile memory with high endurance specifications
• Multiple power-saving modes including idle and power-down

Applications

• Automotive embedded control systems
• Industrial sensor interfaces
• General-purpose microcontroller applications requiring extended temperature ranges

Procurement Notes

Verify the specific suffix MT1 corresponds to the 20-pin QFN package and the 15 MHz speed grade. Confirm that the ordering code matches the automotive temperature range of -40°C to +125°C. Ensure compatibility with existing design tools and programming interfaces before finalizing procurement.

Selection Notes

Select this component when automotive qualification is required alongside standard ATtiny25 functionality. The 15 MHz speed grade offers higher performance than lower-speed variants while maintaining low power consumption. Consider the 20-pin QFN package if space constraints or thermal performance necessitate a surface-mount solution over SOIC packages.

Part Context

This part belongs to the ATtiny25/45/85 Automotive family, manufactured according to ISO-TS-16949 requirements. It shares the same core architecture as industrial versions but undergoes stricter qualification processes. The device is designed for applications demanding robust performance in harsh environments typical of automotive electronics.

Replacement Considerations

Direct replacements include other ATtiny25 variants with compatible pinouts and memory sizes. Verify that substitute parts meet the same AEC-Q100 grade and temperature range requirements. Check for any differences in package dimensions or electrical characteristics that may impact system integration.
