ATTINY87-A15XZ

Overview

The ATtiny87-A15XZ 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 8 MHz at 2.7-5.5V or 16 MHz at 4.5-5.5V within the -40°C to +125°C temperature range. Key peripherals include a LIN 2.1 controller, 10-bit ADC with 11 single-ended channels, two timers/counters, SPI, USI, and DebugWIRE.

Feature Summary

• Integrated LIN 2.1 certified controller for automotive network communication
• Automotive quality grade verified per AEC-Q100 standards
• Advanced RISC architecture enabling single-cycle instruction execution
• On-chip debug system supporting hardware in-system programming

Applications

• Automotive body electronics control modules
• LIN bus node implementation in vehicle networks
• Temperature sensing applications using on-chip sensor
• Low-power embedded control systems requiring high reliability

Procurement Notes

Verify that the ordering suffix 'A15XZ' corresponds to the specific package type (QFN32) and automotive temperature grade (-40°C to +125°C) required for your design. Confirm RoHS compliance status through official Microchip documentation before finalizing procurement specifications.

Selection Notes

Select this component when automotive qualification (AEC-Q100 Grade 1) and integrated LIN controller functionality are mandatory. The device offers a balance of processing speed and peripheral richness suitable for complex body control tasks where standard industrial parts may not suffice due to environmental constraints.

Part Context

This part belongs to the ATtiny87/ATtiny167 family of 8-bit AVR microcontrollers designed specifically for automotive environments. It shares architectural compatibility with the ATtiny167 but provides 8 Kbytes of Flash memory compared to the latter's 16 Kbytes, making it suitable for cost-sensitive applications with moderate code size requirements.

Replacement Considerations

The ATtiny167 is functionally compatible but offers larger memory. For direct pin-to-pin replacement in QFN packages, verify the specific suffix requirements for temperature grade and package variant against the original design specifications.
