Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7130SA55TFI is determined by strict equivalence in the following parameters:

• Memory type, format, and organization (Dual Port Asynchronous SRAM, 1K x 8)
• Memory interface (Parallel)
• Voltage supply range (4.5V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type and pinout (64-TQFP, 10x10)

The 7130LA25TFGI qualifies as a substitute because it maintains identical specifications in all critical parameters listed above. The primary difference is improved performance: the 7130LA25TFGI offers a faster access time and write cycle time of 25 ns compared to the 7130SA55TFI's 55 ns. This faster speed is backward compatible with applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The 7130LA25TFGI is the qualified substitute for the 7130SA55TFI based on the following factors:

• Product Status: The 7130SA55TFI is obsolete, while the 7130LA25TFGI is active and currently in production, ensuring long-term availability and supply chain continuity.
• Compliance: The 7130LA25TFGI is ROHS3 compliant, whereas the 7130SA55TFI is non-compliant. For applications subject to RoHS regulations, the substitute part meets current environmental standards.
• Performance: The 7130LA25TFGI provides improved timing specifications (25 ns versus 55 ns), delivering faster memory access without requiring circuit modifications.
• Functional Equivalence: Both parts maintain identical memory capacity, organization, interface, voltage, temperature range, and package specifications, ensuring direct compatibility at the board level.

Frequently Asked Questions (FAQ)

Q: Can the 7130LA25TFGI directly replace the 7130SA55TFI without circuit modifications?

A: Yes. Both parts share identical memory capacity (8Kbit, 1K x 8), dual-port asynchronous architecture, parallel interface, voltage supply range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and 64-TQFP package pinout. The faster access time of the substitute part is backward compatible with designs specified for the original part.

Q: What is the primary difference between these two parts?

A: The 7130LA25TFGI offers improved timing performance with 25 ns access and write cycle times compared to the 7130SA55TFI's 55 ns specifications. Additionally, the substitute part is active in production and ROHS3 compliant, whereas the original part is obsolete and non-compliant.

Q: Are there any package or pinout differences?

A: No. Both parts use the 64-TQFP (10x10) surface mount package with identical pinout and mechanical dimensions.

Q: What is the moisture sensitivity level for both parts?

A: Both the 7130SA55TFI and 7130LA25TFGI have a Moisture Sensitivity Level (MSL) of 3, with a floor life of 168 hours.

Q: Is the 7130LA25TFGI suitable for new designs?

A: Yes. The 7130LA25TFGI is the recommended choice for new designs due to its active product status, improved performance characteristics, and ROHS3 compliance.
