Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17C010-10CI is determined by the following critical parameters:

• Package Compatibility: Both parts must use the 8-TDFN (8-LAP 6x6) surface mount package to ensure mechanical and electrical fit on existing PCBs.
• Programmable Type: Serial EEPROM functionality must be maintained.
• Operating Temperature Range: The substitute must support the -40°C to 85°C operating window.
• Voltage Supply Range: The substitute must operate within or encompass the 4.5V to 5.5V supply voltage specification.
• Manufacturer Consistency: Microchip Technology parts ensure design continuity and support consistency.

The AT17LV002-10CU meets these substitution criteria while offering enhanced specifications including dual voltage operation (3V ~ 3.6V and 4.5V ~ 5.5V) and increased memory capacity (2MB), with active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The AT17LV002-10CU is the designated substitute for the obsolete AT17C010-10CI. Selection is based on the following engineering factors:

• Product Status: The AT17LV002-10CU maintains active product status with ongoing manufacturer support, whereas the AT17C010-10CI is obsolete and subject to supply discontinuation.
• Regulatory Compliance: The AT17LV002-10CU achieves RoHS3 compliance, meeting current environmental and regulatory requirements. The AT17C010-10CI is RoHS non-compliant.
• Voltage Flexibility: The AT17LV002-10CU supports dual voltage operation (3V ~ 3.6V and 4.5V ~ 5.5V), providing design flexibility while maintaining full compatibility with the original 4.5V ~ 5.5V specification.
• Package Equivalence: Both parts share identical 8-TDFN packaging and pinout, ensuring direct PCB compatibility without layout modifications.
• Memory Capacity: The increased 2MB memory capacity of the AT17LV002-10CU provides functional enhancement without compromising backward compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AT17LV002-10CU be used as a direct replacement for the AT17C010-10CI?

A: Yes. Both parts share the same 8-TDFN package, 8-LAP (6x6) supplier device package, and Serial EEPROM programmable type. The operating temperature range (-40°C to 85°C) is identical. The AT17LV002-10CU supports the original 4.5V ~ 5.5V supply voltage range plus additional 3V ~ 3.6V operation.

Q: What are the key differences between these parts?

A: The primary differences are memory capacity (1Mb versus 2MB), product status (obsolete versus active), RoHS compliance (non-compliant versus RoHS3 compliant), and voltage flexibility (single range versus dual range). All differences favor the AT17LV002-10CU for new designs and production continuity.

Q: Are there any pinout or package considerations?

A: No. Both parts use the identical 8-TDFN package with 8-LAP (6x6) dimensions. Pinout compatibility is assured, and no PCB modifications are required.

Q: Does the increased memory capacity of the AT17LV002-10CU affect compatibility?

A: No. The increased 2MB capacity is a functional enhancement that does not compromise compatibility with designs originally specified for 1Mb. The part operates identically within the original voltage and temperature specifications.

Q: What is the regulatory status of each part?

A: The AT17C010-10CI is RoHS non-compliant and obsolete. The AT17LV002-10CU is RoHS3 compliant and maintains active product status with full manufacturer support.
