ATTINY167-15MZ

Overview

The ATtiny167-15MZ is an automotive-grade 8-bit AVR microcontroller featuring 16 Kbytes of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at speeds up to 16 MHz within a voltage range of 4.5 V to 5.5 V. The device includes a LIN controller certified for LIN 2.1 and 1.3 standards, a 10-bit ADC with 11 single-ended channels, and multiple timer/counters. It utilizes a 32-pad QFN package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Certified LIN 2.1 and 1.3 controller for automotive network communication
• Automotive quality grade verified per AEC-Q100 Grade 1 standards
• Integrated 10-bit analog-to-digital converter with differential channel pairs
• Hardware in-system programming capability via SPI interface

Applications

• Automotive body electronics modules
• LIN bus node implementations
• Temperature sensing applications using on-chip sensor
• General embedded control systems requiring automotive reliability

Procurement Notes

Verify the specific suffix 'MZ' corresponds to the 32-pad QFN package and automotive temperature grade when sourcing. Confirm that the '15' speed grade matches the required 16 MHz operation at 4.5V to 5.5V supply voltages. Ensure compatibility with existing PCB footprints for the QFN-32 form factor during procurement planning.

Selection Notes

Select this component for designs requiring certified LIN communication and high thermal stability. Compare memory requirements against the ATtiny87 variant if only 8 Kbytes of Flash is sufficient. Consider the 16 MHz performance limit at lower voltages versus the 8 MHz limit at full automotive voltage ranges when optimizing power consumption.

Part Context

This part belongs to the ATtiny87/ATtiny167 family, which shares hardware and software compatibility. The primary distinction between these devices is the program memory size, with the ATtiny167 offering double the Flash capacity of the ATtiny87. Both utilize the same AVR enhanced RISC core and peripheral set.

Replacement Considerations

The ATtiny87-15MZ is a pin-compatible alternative within the same family, differing only in having 8 Kbytes of Flash instead of 16 Kbytes. Verify that the application code fits within the reduced memory space before substituting.
