ATTINY167-A15MZ

Overview

The ATtiny167-A15MZ is an automotive-grade, low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It features 16 Kbytes of in-system programmable Flash memory with 10,000 write/erase cycle endurance, 512 bytes of EEPROM, and 512 bytes of internal SRAM. The device operates at speeds up to 16 MHz at 4.5-5.5V or 8 MHz at 2.7-5.5V within an extended temperature range of -40°C to +125°C. Key peripherals include a certified LIN 2.1 controller, a 10-bit ADC with differential channels, multiple timers, and DebugWIRE support.

Feature Summary

• Certified LIN 2.1 controller for automotive network communication
• Automotive quality grade verified per AEC-Q100 standards
• Integrated DebugWIRE system for single-pin on-chip debugging
• Dynamic clock switching capabilities for optimized power management

Applications

• Automotive body electronics systems
• LIN bus node implementations
• Low-power embedded control applications
• Industrial sensor interfaces

Procurement Notes

Verify that the ordering suffix 'A15MZ' corresponds to the specific package variant (QFN32) and the automotive temperature grade (-40°C to +125°C). Confirm that the component meets AEC-Q100 Grade 1 requirements for your specific application environment. Ensure compatibility with existing development tools such as MPLAB X IDE and AVR Dragon programmers.

Selection Notes

Select this model over the ATtiny87 when 16 Kbytes of Flash memory is required for larger codebases. Choose the '-MZ' suffix specifically for the QFN32 package form factor. This part is suitable for designs requiring certified LIN communication without external transceivers. Consider the 16 MHz speed grade only if operating voltage is maintained above 4.5V.

Part Context

This component belongs to the ATtiny87/ATtiny167 family of 8-bit AVR microcontrollers. These devices are hardware and software compatible, differing primarily in Flash memory size. The ATtiny167 provides double the program memory of the ATtiny87 while sharing identical peripheral sets and pinouts across SOIC, TSSOP, and QFN packages.

Replacement Considerations

The ATtiny87 is a functional substitute if 8 Kbytes of Flash memory suffices for the application. Both parts share identical pinouts and instruction sets.
