Equivalent & Substitute Parts for 7130SA35PF

Part Overview

The 7130SA35PF is an 8Kbit dual-port asynchronous SRAM manufactured by Renesas Electronics Corporation in a 64-TQFP package. This parallel interface memory device operates with a 35 ns access time and write cycle time, designed for applications requiring volatile memory storage with simultaneous read/write capability.

The 7130SA35PF is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing system support, maintenance, and new design implementations where this legacy device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7130SA35PF is determined by the following critical parameters:

• Memory capacity: 8Kbit with 1K x 8 organization
• Memory technology: Dual-port asynchronous SRAM
• Interface type: Parallel
• Package format: 64-TQFP (14x14)
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C

The 7130LA20PFG qualifies as a direct substitute. It maintains identical memory capacity, organization, technology, interface, package, voltage, and temperature specifications. The primary difference is improved performance: the 7130LA20PFG provides 20 ns access and write cycle times compared to the 7130SA35PF's 35 ns specification. This faster timing is backward-compatible with applications designed for the 7130SA35PF.

Parameter Comparison

Engineering Selection Recommendations

The 7130LA20PFG is the qualified substitute for the 7130SA35PF based on the following factors:

The 7130SA35PF is obsolete, making the 7130LA20PFG the appropriate choice for system continuity. The 7130LA20PFG maintains active product status with full availability.

The 7130LA20PFG achieves ROHS3 compliance, whereas the 7130SA35PF is non-compliant. For applications subject to RoHS regulations or environmental standards, the 7130LA20PFG satisfies current compliance requirements.

Performance improvement is inherent in the substitution: the 7130LA20PFG delivers 20 ns timing versus the 7130SA35PF's 35 ns specification. This faster access and write cycle time is fully backward-compatible with designs specified for the original part.

All other electrical and mechanical parameters remain identical, ensuring direct functional equivalence in circuit implementation.

Frequently Asked Questions (FAQ)

Q: Can the 7130LA20PFG replace the 7130SA35PF in existing designs?

A: Yes. The 7130LA20PFG is a direct substitute. It maintains identical memory capacity (8Kbit), organization (1K x 8), technology (dual-port asynchronous SRAM), interface (parallel), package (64-TQFP), voltage supply (4.5V ~ 5.5V), and operating temperature range (0°C ~ 70°C). The faster 20 ns timing is backward-compatible with applications designed for 35 ns operation.

Q: What is the primary difference between these parts?

A: The 7130LA20PFG provides improved access and write cycle times of 20 ns compared to the 7130SA35PF's 35 ns specification. Additionally, the 7130LA20PFG is active product status with ROHS3 compliance, while the 7130SA35PF is obsolete and RoHS non-compliant.

Q: Are the packages identical?

A: Yes. Both parts use the 64-TQFP (14x14) surface mount package with identical pinout and mechanical dimensions.

Q: What voltage levels do these parts require?

A: Both parts operate with a supply voltage range of 4.5V ~ 5.5V and are compatible with standard 5V logic systems.

Q: Is the 7130LA20PFG suitable for new designs?

A: Yes. The 7130LA20PFG is active product status with current availability and ROHS3 compliance, making it appropriate for new system development and long-term production support.
