Substitute Part Grouping Explanation

Substitution eligibility for the ATMEGA162V-8AI is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: AVR
• Core Size: 8-Bit
• Operating Speed: 8MHz
• Program Memory: 16KB FLASH (8K x 16)
• EEPROM: 512 x 8
• RAM: 1K x 8
• I/O Count: 35 pins
• Supply Voltage Range: 1.8V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 44-TQFP (10x10)
• Mounting Type: Surface Mount
• Connectivity: EBI/EMI, SPI, UART/USART
• Peripherals: Brown-out Detect/Reset, POR, PWM, WDT

The ATMEGA162V-8AU meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ATMEGA162V-8AU is the direct substitute for the ATMEGA162V-8AI. Both parts share identical electrical specifications, memory configuration, I/O architecture, and package form factor. The primary distinction is product lifecycle status: the ATMEGA162V-8AI is Obsolete, while the ATMEGA162V-8AU is Active with verified programmability and ROHS3 compliance certification. For new designs or production continuity, the ATMEGA162V-8AU is the appropriate selection. The substitute part maintains full functional compatibility while offering improved regulatory compliance and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Are ATMEGA162V-8AI and ATMEGA162V-8AU pin-compatible?

A: Yes. Both parts use the 44-TQFP (10x10) package with identical pinout, electrical characteristics, and I/O configuration. Direct PCB-level substitution is supported without layout modification.

Q: What is the difference between the -8AI and -8AU suffix designations?

A: The suffix indicates packaging format. The -8AI variant uses tube packaging, while the -8AU variant uses tray packaging. The electrical and functional specifications are identical.

Q: Can I use ATMEGA162V-8AU in designs originally specified for ATMEGA162V-8AI?

A: Yes. The ATMEGA162V-8AU provides full functional equivalence with identical memory, speed, I/O count, and peripheral integration. No firmware or hardware modifications are required.

Q: What is the significance of the Active product status for ATMEGA162V-8AU?

A: Active status indicates the part is in current production with ongoing manufacturer support, technical documentation updates, and supply chain availability. This contrasts with the Obsolete status of ATMEGA162V-8AI, which has reached end-of-life.

Q: Does ATMEGA162V-8AU meet current regulatory requirements?

A: Yes. The ATMEGA162V-8AU is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The ATMEGA162V-8AI is RoHS non-compliant, making the substitute preferable for regulated applications.

Q: Are there inventory considerations when transitioning from ATMEGA162V-8AI to ATMEGA162V-8AU?

A: The ATMEGA162V-8AU has significantly higher inventory availability (5,000,100 units) compared to the ATMEGA162V-8AI (2,200 units), supporting sustained production and reducing supply chain risk.
