AT25080B-XPDGV-T Equivalent & Substitute Parts

Part Overview

The AT25080B-XPDGV-T is an 8Kbit EEPROM memory IC manufactured by Microchip Technology, designed for serial peripheral interface (SPI) communication at 5 MHz. This non-volatile memory device operates across a supply voltage range of 2.5V to 5.5V and is qualified to automotive standards (AEC-Q100). The part is currently in active production status with 867 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are met, enabling component interchangeability in applications where the original part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT25080B-XPDGV-T is determined by strict alignment of the following critical parameters:

• Memory capacity: 8Kbit
• Memory organization: 1K x 8
• Interface protocol: SPI
• Clock frequency: 5 MHz
• Write cycle time: 5ms
• Package type: 8-TSSOP with identical physical dimensions
• Mounting type: Surface Mount
• RoHS and environmental compliance: ROHS3 Compliant

The identified substitute part R1EX25008ATA00I#S0 (Renesas Electronics Corporation) meets all electrical and mechanical requirements for direct substitution. Voltage supply range and operating temperature specifications must be verified against application requirements, as these parameters may differ between the main part and substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the AT25080B-XPDGV-T and R1EX25008ATA00I#S0 are active production parts with ROHS3 compliance and identical moisture sensitivity ratings. The Microchip part supports a wider operating temperature range (-40°C to 125°C) and lower minimum supply voltage (2.5V), while the Renesas substitute operates from 1.8V minimum and is rated to 85°C maximum.

Selection between these parts depends on application-specific requirements for temperature range and supply voltage. Both parts meet the core electrical and mechanical specifications for 8Kbit SPI EEPROM functionality in 8-TSSOP packaging.

Frequently Asked Questions (FAQ)

Q: Can R1EX25008ATA00I#S0 replace AT25080B-XPDGV-T in all applications?

A: Direct substitution is possible when the application operates within the Renesas part's specifications: supply voltage 1.8V to 5.5V and operating temperature -40°C to 85°C. Applications requiring operation above 85°C or below 2.5V supply voltage require the Microchip part.

Q: Are the package dimensions identical?

A: Yes. Both parts use 8-TSSOP packaging with 0.173" width and 4.40mm physical dimensions, enabling direct PCB footprint compatibility.

Q: What is the significance of the SPI interface match?

A: SPI interface compatibility ensures that firmware and hardware communication protocols remain unchanged during substitution. Both parts operate at 5 MHz clock frequency with identical 5ms write cycle time.

Q: Do both parts meet automotive qualification standards?

A: The AT25080B-XPDGV-T carries AEC-Q100 automotive qualification. The Renesas R1EX25008ATA00I#S0 specifications provided do not indicate automotive qualification status.

Q: What is the difference in supply voltage range?

A: The Microchip part operates from 2.5V to 5.5V, while the Renesas part operates from 1.8V to 5.5V. The Renesas part supports lower voltage applications but both are compatible with standard 3.3V and 5V logic systems.
