ATTINY87-15SZ

Overview

The ATtiny87-15SZ is an automotive-grade 8-bit AVR microcontroller featuring 8 Kbytes of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at frequencies up to 16 MHz between 4.5 V and 5.5 V, or up to 8 MHz across the full 2.7 V to 5.5 V range. The device includes a LIN controller, 10-bit ADC with differential channels, and supports the –40°C to +125°C temperature range.

Feature Summary

• Integrated LIN 2.1 certified controller for automotive network communication
• Hardware and software compatible with ATtiny167 for scalable design
• AEC-Q100 Grade 1 qualified for automotive reliability standards
• Advanced RISC architecture enabling single-cycle instruction execution

Applications

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

Procurement Notes

Verify that the ordering suffix 'Z' corresponds to the QFN32 package and the specific speed grade required for your voltage and temperature constraints. Confirm AEC-Q100 Grade 1 compliance is necessary for your automotive application requirements before finalizing procurement.

Selection Notes

Select this model when automotive qualification (AEC-Q100 Grade 1) and LIN controller integration are mandatory. Choose over the standard ATtiny87 if operating within the extended industrial/automotive temperature range of –40°C to +125°C is required. Ensure the 8 Kbyte Flash capacity meets your code storage needs compared to the 16 Kbyte variant.

Part Context

This component belongs to the ATtiny87/ATtiny167 family of 8-bit AVR microcontrollers designed for high-performance, low-power applications. It shares the same core architecture and peripheral set as the ATtiny167, differing primarily in Flash memory size. The series is specifically engineered to meet stringent automotive quality standards.

Replacement Considerations

The ATtiny167 is functionally compatible but offers 16 Kbytes of Flash instead of 8 Kbytes. Standard commercial grade variants like ATtiny87-PU lack the specified automotive temperature range and AEC-Q100 qualification.
