ATTINY167-A15XD

Overview

The ATtiny167-A15XD 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 at 4.5-5.5V or 8 MHz at 2.7-5.5V within the -40°C to +125°C temperature range. Key peripherals include a LIN 2.1 controller, 11-channel 10-bit ADC with differential pairs, two timer/counters, SPI/USI interfaces, and DebugWIRE.

Feature Summary

• Certified LIN 2.1 controller for automotive network communication
• High-resolution 10-bit ADC with selectable gain and differential channels
• Automotive qualified reliability meeting AEC-Q100 Grade 1 standards
• Integrated DebugWIRE system for single-pin on-chip debugging

Applications

• Automotive engine control units (ECU)
• LIN bus node implementations
• Sensor interface modules
• Body electronics controllers

Procurement Notes

Verify that the ordering suffix 'A15XD' corresponds to the specific package type, temperature grade, and tape-and-reel configuration required for your assembly line. Confirm that the component meets the AEC-Q100 Grade 1 qualification requirements for your specific automotive application environment before finalizing procurement.

Selection Notes

Select this model over the ATtiny87 variant when 16 Kbytes of Flash memory is necessary for complex application code. Ensure the design supports the required operating voltage range and utilizes the integrated LIN controller if automotive networking is a primary requirement. Verify package availability matches the PCB footprint constraints.

Part Context

This device belongs to the ATtiny87/167 family of 8-bit AVR microcontrollers designed for embedded control applications. It shares hardware and software compatibility with the ATtiny87, differing primarily in program memory capacity. The family is optimized for low-power consumption while delivering high performance through its enhanced RISC architecture.

Replacement Considerations

The ATtiny87 is functionally compatible but contains only 8 Kbytes of Flash. Other ATtiny series devices may require significant firmware adaptation due to peripheral differences.
