Renesas Electronics 7130LA55PFI SRAM Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 7130LA55PFI is a volatile dual-port asynchronous SRAM memory IC with 8Kbit capacity organized as 1K x 8, housed in a 64-TQFP surface mount package. This component operates at 4.5V to 5.5V supply voltage with an access time of 55 nanoseconds and is designed for parallel memory interface applications requiring high-speed data access.

The 7130LA55PFI is classified as obsolete. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the 7130LA55PFI is determined by strict equivalence across the following critical parameters:

Memory capacity, organization, and interface type must remain identical: 8Kbit, 1K x 8 organization, and parallel interface are non-negotiable requirements for functional compatibility.

Package and mounting specifications must match exactly: 64-TQFP (14x14) surface mount package ensures mechanical and electrical compatibility with existing PCB layouts.

Voltage supply range and operating temperature range must be equal or broader than the original specification to ensure operation across all intended conditions.

Access time and write cycle time may be equal to or faster than the original specification without affecting compatibility. Faster timing parameters represent performance improvements and do not create functional conflicts.

The 7130LA25PFGI meets all substitution criteria. It maintains identical memory capacity, organization, interface type, package configuration, voltage supply range, and operating temperature range. The 25 nanosecond access and write cycle times are faster than the original 55 nanosecond specification, providing improved performance without compatibility issues.

Engineering Selection Recommendations

The 7130LA25PFGI is the direct substitute for the 7130LA55PFI. Both components are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications with the exception of access and write cycle times.

The 7130LA25PFGI offers superior performance characteristics with 25 nanosecond timing versus the original 55 nanosecond specification. This faster access time provides improved system performance without introducing any compatibility constraints.

The 7130LA25PFGI carries Active product status, ensuring ongoing manufacturer support and availability. The original 7130LA55PFI is classified as Obsolete, making the 7130LA25PFGI the appropriate long-term solution for new designs and legacy system updates.

The 7130LA25PFGI achieves ROHS3 compliance, meeting current environmental and regulatory standards. The original part is RoHS non-compliant, making the substitute the preferred choice for applications subject to RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7130LA25PFGI directly replace the 7130LA55PFI in existing designs?

A: Yes. The 7130LA25PFGI is a direct substitute. Both components share identical memory capacity, organization, interface type, package configuration, voltage supply range, and operating temperature range. The faster access time of the 7130LA25PFGI does not create compatibility issues.

Q: What is the difference between the 7130LA55PFI and 7130LA25PFGI?

A: The primary difference is access and write cycle time. The 7130LA55PFI operates at 55 nanoseconds, while the 7130LA25PFGI operates at 25 nanoseconds. The 7130LA25PFGI also carries Active product status and ROHS3 compliance, compared to Obsolete status and RoHS non-compliance for the original part.

Q: Are the packages identical between these two parts?

A: Yes. Both components use the 64-TQFP (14x14) surface mount package. PCB layouts and footprints are identical, requiring no design modifications for substitution.

Q: Does the faster access time of the 7130LA25PFGI affect system compatibility?

A: No. Faster access time represents an improvement and does not create functional conflicts. Systems designed for 55 nanosecond access time operate correctly with 25 nanosecond components.

Q: What is the voltage supply requirement for both parts?

A: Both the 7130LA55PFI and 7130LA25PFGI operate across a 4.5V to 5.5V supply voltage range. No power supply modifications are required for substitution.

Q: Are there any temperature range differences between these components?

A: No. Both components operate across the identical -40°C to 85°C temperature range. No thermal design changes are necessary.
