AT17F080-30TQI Equivalent & Substitute Parts

Part Overview

The AT17F080-30TQI is a Flash memory integrated circuit manufactured by Microchip Technology, classified as a programmable memory device with 8Mb capacity. This component is designated as obsolete, which necessitates identification of equivalent substitute parts for ongoing design requirements and production continuity. The part operates within a supply voltage range of 2.97V to 3.63V and supports industrial temperature ranges from -40°C to 85°C in a 44-TQFP surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17F080-30TQI is determined by the following critical parameters that must remain consistent across equivalent parts:

• Memory type: FLASH programmable memory
• Memory capacity: 8Mb
• Supply voltage range: 2.97V ~ 3.63V
• Operating temperature range: -40°C ~ 85°C
• Base product number: AT17F080
• Manufacturer: Microchip Technology

The AT17F080-30JU qualifies as a direct substitute based on identical electrical specifications and memory characteristics. The primary difference lies in packaging configuration: the substitute uses a 20-PLCC (J-Lead) package instead of the 44-TQFP package, which represents a mechanical variation rather than a functional limitation. Both parts share the same base product designation (AT17F080) and maintain equivalent electrical performance across all specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

The AT17F080-30JU is the qualified substitute for the obsolete AT17F080-30TQI. Selection of this substitute is supported by the following factors:

• Identical electrical specifications across all operating parameters
• Active product status ensures continued availability and supply chain reliability
• ROHS3 compliance of the substitute addresses regulatory requirements not met by the original part
• Equivalent moisture sensitivity classification maintains handling and storage requirements
• Both parts carry identical ECCN and HTSUS classifications

PCB layout modifications are required to accommodate the package transition from 44-TQFP to 20-PLCC, as pin count and footprint geometry differ between these package types. Functional compatibility is confirmed; however, physical board redesign is necessary for implementation.

Frequently Asked Questions (FAQ)

Q: Can the AT17F080-30JU be used as a direct pin-for-pin replacement?

A: No. The AT17F080-30JU uses a 20-PLCC package with 20 pins, while the AT17F080-30TQI uses a 44-TQFP package with 44 pins. Pin assignments differ between these package types. PCB layout and schematic modifications are required.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts maintain identical supply voltage ranges (2.97V ~ 3.63V), operating temperature ranges (-40°C ~ 85°C), memory capacity (8Mb), and memory type (FLASH). Electrical performance is equivalent.

Q: What is the significance of the product status difference?

A: The AT17F080-30TQI is obsolete, indicating discontinued manufacturing and limited availability. The AT17F080-30JU is active, ensuring ongoing production and reliable supply chain access for new designs and production runs.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance is a regulatory and environmental classification. The ROHS3 compliance of the AT17F080-30JU meets current environmental standards, while the original part does not. This affects procurement eligibility and regulatory compliance for end applications but does not impact electrical functionality.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts are classified as MSL 3 (168 Hours), requiring identical handling, storage, and reflow procedures during assembly.
