Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATMEGA169V-1AC is determined by strict equivalence in the following core parameters:

• Core processor architecture (AVR)
• Core size (8-Bit)
• Program memory capacity (16KB FLASH)
• RAM capacity (1K x 8)
• EEPROM capacity (512 x 8)
• Package type (64-TQFP)
• Supply voltage range (1.8V ~ 5.5V)
• Peripheral set (SPI, UART/USART, USI, PWM, WDT, Brown-out Detect/Reset, LCD, POR)
• Data converter specification (A/D 8x10b)

The ATMEGA169PV-8AU meets all these criteria and qualifies as a direct substitute. Variations in operating speed, temperature range, product status, and compliance certifications do not affect functional substitutability within systems designed for the ATMEGA169V-1AC.

Parameter Comparison

Engineering Selection Recommendations

The ATMEGA169PV-8AU is the qualified substitute for the ATMEGA169V-1AC based on the following factors:

• Identical core architecture, memory configuration, and peripheral set ensure functional compatibility
• Active product status provides ongoing availability and supply chain continuity
• ROHS3 compliance meets current environmental and regulatory requirements
• Extended operating temperature range (-40°C ~ 85°C) accommodates broader application environments compared to the original part (0°C ~ 70°C)
• Higher clock speed (8MHz versus 1MHz) provides performance headroom without affecting backward compatibility in timing-critical applications
• Identical package and pinout enable direct PCB substitution

Frequently Asked Questions (FAQ)

Q: Can the ATMEGA169PV-8AU be used as a direct replacement for the ATMEGA169V-1AC?

A: Yes. Both devices share identical core architecture, memory capacity, peripheral configuration, and package specifications. The substitute part is pin-compatible and functionally equivalent.

Q: What are the differences between these parts?

A: The ATMEGA169PV-8AU operates at 8MHz compared to 1MHz for the ATMEGA169V-1AC, supports an extended temperature range (-40°C to 85°C versus 0°C to 70°C), and carries ROHS3 compliance certification. The substitute has 54 I/O pins versus 53 on the original part. These differences do not affect substitutability.

Q: Are there any package or pinout differences?

A: No. Both parts use the 64-TQFP (14x14) package with identical pinout and mounting specifications.

Q: Does the higher clock speed of the substitute affect compatibility?

A: No. The ATMEGA169PV-8AU operates at a higher maximum frequency but is fully backward compatible. Applications designed for the 1MHz part will function correctly with the 8MHz substitute.

Q: What is the significance of the RoHS compliance difference?

A: The ATMEGA169V-1AC is RoHS non-compliant, while the ATMEGA169PV-8AU is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the substitute part meets current environmental standards.

Q: Are the supply voltage specifications identical?

A: Yes. Both parts operate across the same supply voltage range of 1.8V to 5.5V.
