ATTINY167-15XZ

Overview

The ATtiny167-15XZ is an automotive-grade, 8-bit AVR microcontroller featuring 16K bytes of in-system programmable flash memory, 512 bytes of EEPROM, and 512 bytes of internal SRAM. It operates at speeds up to 16 MHz between 4.5V and 5.5V, or up to 8 MHz across the full 2.7V to 5.5V range. 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 16 general-purpose I/O lines. It supports DebugWIRE on-chip debugging and hardware ISP via SPI.

Feature Summary

• Certified LIN 2.1 and 1.3 controller for automotive network communication
• Automotive quality grade verified per AEC-Q100 standards
• On-chip DebugWIRE system for efficient development and debugging
• 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 that the specific suffix '15XZ' corresponds to the required automotive temperature grade (-40°C to +125°C) and package type (SOIC, QFN, or TSSOP). Confirm that the ordering information matches the exact pinout and memory configuration required for the design. Ensure compliance with ISO-TS-16949 manufacturing standards if specified by the project requirements.

Selection Notes

Select this component when 16K bytes of program memory are necessary, distinguishing it from the 8K byte ATtiny87 variant. Choose this part for designs requiring certified LIN protocol support and operation within the extended automotive temperature range. Consider the available packages (SOIC, QFN, TSSOP) based on board space constraints and thermal management needs.

Part Context

This microcontroller belongs to the Atmel ATtiny87/ATtiny167 family, which shares identical hardware architecture and software compatibility. The primary distinction between the two devices is the program memory size, with the ATtiny167 offering double the flash capacity of the ATtiny87 while maintaining the same peripheral set and pin configurations.

Replacement Considerations

The ATtiny87-15XZ is a hardware and software compatible alternative with reduced flash memory (8K bytes). Verify that the application code fits within the smaller memory footprint before substituting.
