7130SA55CM Equivalent & Substitute Parts

Part Overview

The 7130SA55CM is a dual-port asynchronous SRAM memory IC manufactured by Renesas Electronics Corporation. This 8Kbit parallel memory device operates with a 55 ns access time and is housed in a 64-TQFP (14x14) surface mount package. The part is classified as obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the 7130SA55CM is determined by the following critical parameters:

Core Compatibility Requirements:

Memory Type: Volatile SRAM (dual-port, asynchronous architecture)
Memory Size: 8Kbit capacity
Memory Organization: 1K x 8 configuration
Memory Interface: Parallel interface
Supply Voltage: 4.5V ~ 5.5V range
Package Type: 64-TQFP (14x14) surface mount

The 7130LA25PFGI qualifies as a manufacturer-recommended substitute because it maintains identical specifications across all core parameters. While the access time differs (25 ns versus 55 ns), faster access time represents an improvement in performance and does not compromise backward compatibility. The substitute operates within the same voltage range and maintains the same pinout and package footprint, enabling direct replacement in existing designs.

Engineering Selection Recommendations

The 7130LA25PFGI is the manufacturer-recommended substitute for the 7130SA55CM. Selection of this substitute is supported by the following factors:

Product Status: The 7130SA55CM is classified as obsolete, while the 7130LA25PFGI maintains active product status with current manufacturing support and documented availability (2100 pcs in stock).

Compliance & Certifications: The 7130LA25PFGI carries ROHS3 compliance certification and REACH unaffected status, meeting modern regulatory requirements for electronic components. These certifications are not specified for the obsolete 7130SA55CM.

Performance Characteristics: The substitute provides improved access time (25 ns versus 55 ns) and write cycle time, delivering enhanced performance without compromising backward compatibility. The faster timing specification does not introduce compatibility issues in systems designed for the original 55 ns part.

Physical & Electrical Compatibility: Identical package footprint (64-TQFP 14x14), supply voltage range (4.5V ~ 5.5V), and parallel interface ensure direct PCB-level replacement without design modifications.

Frequently Asked Questions (FAQ)

Q: Can the 7130LA25PFGI directly replace the 7130SA55CM on existing PCBs?

A: Yes. Both parts share identical pinout, package footprint (64-TQFP 14x14), and supply voltage specifications (4.5V ~ 5.5V). No PCB modifications are required for physical or electrical substitution.

Q: Why does the substitute have faster access time (25 ns vs. 55 ns)?

A: The 7130LA25PFGI represents a performance-enhanced variant within the same product family. Faster access time is a specification improvement and does not create compatibility issues in systems designed for the original 55 ns timing.

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

A: The 7130SA55CM is obsolete and no longer manufactured. The 7130LA25PFGI is an active product with ongoing manufacturing support, documented availability, and compliance certifications, making it suitable for new designs and ongoing production requirements.

Q: Are there compliance differences between these parts?

A: The 7130LA25PFGI carries ROHS3 compliance and REACH unaffected certification. The 7130SA55CM compliance status is not documented. For applications requiring regulatory compliance documentation, the substitute provides certified compliance.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute?

A: The 7130LA25PFGI carries MSL 3 (168 Hours) classification, indicating standard moisture sensitivity handling requirements for surface mount components.

Q: Can the substitute be used in designs originally specified for the 7130SA55CM?

A: Yes. Identical memory capacity (8Kbit), organization (1K x 8), interface type (parallel), and voltage specifications ensure functional compatibility. The improved access time provides performance headroom without introducing timing violations in existing designs.
