ATTINY167-A15XZ

Overview

The ATtiny167-A15XZ is an automotive-grade 8-bit AVR microcontroller featuring 16 Kbytes of in-system programmable flash memory, 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 certified LIN 2.1 controller, a 10-bit ADC with differential channels, and multiple timer/counter units. It supports DebugWIRE for on-chip debugging and offers three power-saving modes. The component is qualified to AEC-Q100 Grade 1 standards and functions reliably across the extended temperature range of –40°C to +125°C.

Feature Summary

• Certified LIN 2.1 controller for automotive network communication
• AEC-Q100 Grade 1 qualification for automotive reliability
• Integrated DebugWIRE system for hardware debugging
• 10-bit ADC with programmable gain and differential inputs

Applications

• Automotive body electronics control modules
• LIN bus node implementations
• Temperature sensing systems using internal sensors
• Low-power embedded control applications

Procurement Notes

Verify that the ordering suffix 'A15XZ' corresponds to the specific package type and tape-and-reel configuration required for your assembly process. Confirm the automotive grade designation matches your project's environmental specifications. Ensure compatibility with existing development tools such as MPLAB X IDE and AVR programmers before finalizing procurement.

Selection Notes

Select this model when 16 Kbytes of program memory is required for complex firmware logic. Choose this variant over the ATtiny87 if larger code storage or data tables are necessary. Consider the integrated LIN controller for direct vehicle network connectivity without external transceivers. Evaluate the 16 MHz speed grade against power consumption requirements in active states.

Part Context

This component belongs to the ATtiny87/ATtiny167 family of 8-bit AVR microcontrollers. It shares identical pinouts, instruction sets, and peripheral configurations with the ATtiny87, differing primarily in flash memory capacity. The family is designed for cost-effective embedded solutions requiring robust performance and low power consumption in compact packages.

Replacement Considerations

The ATtiny87 is a functional substitute if reduced memory capacity is acceptable. Verify that any replacement maintains the same package footprint and pinout compatibility. Ensure the alternative part meets the same AEC-Q100 automotive qualification standards.
