ATTINY167-A15SZ

Overview

The ATtiny167-A15SZ 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 within a voltage range of 2.7 V to 5.5 V and supports clock frequencies up to 16 MHz at the higher voltage range. The device includes a certified LIN 2.1 controller, a 10-bit ADC with differential channels, and multiple timer/counters. Packaged in a 20-pin SOIC or TSSOP, it functions reliably across an extended temperature range of –40°C to +125°C.

Feature Summary

• Certified LIN 2.1 controller for automotive network communication
• Automotive quality grade verified per AEC-Q100 standards
• Integrated 10-bit analog-to-digital converter with differential inputs
• Hardware debugWIRE system for on-chip debugging

Applications

• Automotive body electronics control modules
• LIN bus node implementations in vehicle networks
• Sensor interface units requiring analog signal processing
• Industrial controllers operating in harsh thermal environments

Procurement Notes

Verify that the ordering suffix 'A15SZ' corresponds to the specific package type (SOIC/TSSOP) and temperature grade (Z for –40°C to +125°C). Confirm the component meets AEC-Q100 Grade 1 requirements for your application. Ensure the source documentation explicitly lists this part number variant to avoid confusion with non-automotive or different package versions.

Selection Notes

Select this model when automotive reliability and LIN certification are mandatory. The 16 Kbyte Flash capacity distinguishes it from the ATtiny87. Ensure the design utilizes the 20-pin package constraints. Verify that the 16 MHz speed grade is sufficient for the required instruction throughput at the target supply voltage.

Part Context

This component belongs to the ATtiny87/ATtiny167 family of 8-bit AVR microcontrollers designed for embedded control. It shares architectural compatibility with the ATtiny87 but offers double the program memory. The series is characterized by high performance per watt and robust peripheral sets tailored for cost-sensitive yet demanding applications.

Replacement Considerations

The ATtiny87 is a hardware-compatible alternative with reduced Flash memory. Other ATtiny series devices may offer different pin counts or peripheral sets but lack the specific automotive qualification and LIN certification found in this model.
