Renesas 7130LA55PF8 SRAM Equivalent & Substitute Parts

Part Overview

The Renesas 7130LA55PF8 is an 8Kbit dual-port asynchronous SRAM memory IC in a 64-TQFP surface mount package. This part operates with a 55 ns access time and write cycle time, designed for parallel memory applications requiring volatile storage. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support, maintenance, and new design implementations where this memory capacity and interface type are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7130LA55PF8 is determined by the following critical parameters:

• Memory capacity (8Kbit) and organization (1K x 8)
• Dual-port asynchronous SRAM technology
• Parallel memory interface
• 64-TQFP package footprint and pinout compatibility
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (0°C ~ 70°C)

The 7130LA20PFG8 qualifies as a direct substitute because it maintains identical memory capacity, organization, technology, interface type, package, voltage specifications, and temperature range. The primary difference is improved access time and write cycle time performance (20 ns versus 55 ns), which represents a performance upgrade rather than a functional incompatibility.

Engineering Selection Recommendations

The 7130LA20PFG8 is the qualified substitute for the obsolete 7130LA55PF8. Selection of this substitute is supported by the following factors:

• The substitute maintains full functional and electrical compatibility across all critical memory parameters
• The substitute is in active product status, ensuring long-term availability and supply chain continuity
• The substitute achieves ROHS3 compliance, meeting current environmental and regulatory requirements
• The substitute offers improved access time and write cycle time performance (20 ns), providing performance headroom for legacy system designs
• Identical package footprint and pinout enable direct board-level replacement without layout modifications
• Both parts share identical supply voltage and operating temperature specifications

Frequently Asked Questions (FAQ)

Q: Can the 7130LA20PFG8 directly replace the 7130LA55PF8 on existing PCBs?

A: Yes. Both parts use the 64-TQFP (14x14) package with identical pinout and footprint. Direct soldering replacement is possible without PCB layout changes.

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

A: The 7130LA20PFG8 provides faster memory access and write cycle times (20 ns) compared to the 7130LA55PF8 (55 ns). This represents a performance upgrade. All other electrical and functional specifications remain identical.

Q: Is the 7130LA20PFG8 suitable for new designs?

A: Yes. The 7130LA20PFG8 is in active product status with ROHS3 compliance, making it appropriate for new designs requiring 8Kbit dual-port asynchronous SRAM with parallel interface in a 64-TQFP package.

Q: Are there packaging differences between these parts?

A: The 7130LA55PF8 is supplied in bulk packaging, while the 7130LA20PFG8 is supplied in Tape & Reel (TR) format. Both are surface mount compatible.

Q: What supply voltage do these parts require?

A: Both parts operate within the 4.5V to 5.5V supply voltage range and are rated for 0°C to 70°C operating temperature.

Q: Why is the original part listed as obsolete?

A: The 7130LA55PF8 has been discontinued by Renesas Electronics Corporation. The 7130LA20PFG8 serves as the active replacement, offering improved performance specifications while maintaining backward compatibility.
