Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATMEGA8515-16AI is determined by strict equivalence across the following parameters: core processor architecture (AVR), core size (8-Bit), operating frequency (16MHz), program memory capacity (8KB FLASH), EEPROM size (512 x 8), RAM size (512 x 8), supply voltage range (4.5V ~ 5.5V), I/O count (35), connectivity interfaces (EBI/EMI, SPI, UART/USART), peripheral features (Brown-out Detect/Reset, POR, PWM, WDT), operating temperature range (-40°C ~ 85°C), and physical package format (44-TQFP 10x10).

The ATMEGA8515-16AU meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The ATMEGA8515-16AU is the appropriate substitute for the obsolete ATMEGA8515-16AI. Both devices are electrically and mechanically identical across all functional parameters. The ATMEGA8515-16AU carries Active product status, ensuring continued availability and supply chain support. Additionally, the ATMEGA8515-16AU meets ROHS3 compliance requirements, whereas the ATMEGA8515-16AI is RoHS non-compliant. For applications requiring regulatory compliance with modern environmental standards, the ATMEGA8515-16AU is the mandated selection. Both devices maintain identical moisture sensitivity levels and REACH status.

Frequently Asked Questions (FAQ)
