ATTINY87-A15MZ

Overview

The ATTINY87-A15MZ is an automotive-grade 8-bit AVR microcontroller featuring 8K bytes of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at frequencies up to 16 MHz within a voltage range of 4.5V to 5.5V, or up to 8 MHz between 2.7V and 5.5V. The device supports the –40°C to +125°C temperature range and includes a LIN controller, 10-bit ADC with differential channels, and DebugWIRE.

Feature Summary

• Integrated LIN 2.1 certified controller for automotive network communication
• Hardware and software compatibility with ATtiny167 for scalable design
• AEC-Q100 Grade 1 qualification ensuring high reliability in automotive environments
• Advanced RISC architecture enabling single-cycle execution for efficient processing

Applications

• Automotive body electronics and control modules
• LIN bus node implementation in vehicle networks
• Temperature sensing applications using on-chip sensors
• General embedded control systems requiring automotive grade components

Procurement Notes

Verify that the specific suffix A15MZ corresponds to the intended package type and temperature grade as defined by Microchip Technology. Confirm that the ordering information matches the required automotive specifications before procurement. Ensure compatibility with existing development tools and programming interfaces.

Selection Notes

Select this component when automotive certification (AEC-Q100) and LIN interface capabilities are mandatory. It serves as a direct hardware and software compatible alternative to the ATtiny167 if 8K Flash is sufficient. Consider the operating voltage requirements, specifically the 4.5V minimum for 16MHz operation, against system power constraints.

Part Context

This part belongs to the ATtiny87/ATtiny167 family of 8-bit AVR microcontrollers designed for robust embedded applications. The series is characterized by its high performance, low power consumption, and extensive peripheral set including timers, ADCs, and serial interfaces suitable for complex control tasks.

Replacement Considerations

The ATtiny167 is a verified substitute offering identical functionality with increased Flash memory capacity. Other ATtiny87 variants with different package suffixes may be used if pin compatibility and environmental ratings match the application requirements.
