Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATTINY167-15MZ is determined by strict equivalence across the following critical parameters:

Core architecture and instruction set compatibility (AVR 8-bit processor) Memory configuration (16KB FLASH, 512 bytes EEPROM, 512 bytes RAM) Operating frequency (16MHz) I/O count (16 pins) Supply voltage range (2.7V ~ 5.5V) Integrated peripheral set (I2C, SPI, UART/USART, LINbus, USI, PWM, temperature sensor, watchdog timer, brown-out detection) Package form factor (32-VFQFN with exposed pad) Automotive qualification (AEC-Q100) Operating temperature range (-40°C ~ 125°C)

The ATTINY167-A15MZ meets all these criteria as a parametric equivalent. The primary distinction is product status: the original part is obsolete while the substitute is active, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The ATTINY167-A15MZ is the direct active equivalent for the obsolete ATTINY167-15MZ. Both parts share identical electrical specifications, memory configuration, peripheral integration, and package form factor. The substitute maintains full AEC-Q100 automotive qualification and ROHS3 compliance, ensuring compatibility with existing design requirements and regulatory obligations.

Selection of the ATTINY167-A15MZ is appropriate for new production, design revisions, and long-term supply chain continuity. The active product status ensures availability and ongoing manufacturer support.
