Renesas Electronics 7005SJ SRAM Dual Port Memory IC - Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 7005SJ is a 64Kbit dual port asynchronous SRAM memory IC with 8K x 8 organization, housed in a 68-PLCC surface mount package. This component is classified as obsolete product status, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. The dual port architecture enables simultaneous independent read and write operations, making it suitable for applications requiring high-speed parallel memory access.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 7005SJ is determined by strict equivalence across the following critical parameters:

Memory Capacity & Organization: The substitute must maintain 64Kbit total capacity with 8K x 8 organization to ensure address bus and data bus compatibility with existing circuit designs.

Dual Port Asynchronous Architecture: The substitute must retain dual port SRAM functionality with asynchronous operation to preserve independent simultaneous read/write capability.

Parallel Interface: The substitute must use parallel memory interface matching the original part's pin configuration and signal protocol.

Package Compatibility: The substitute must use 68-PLCC (24.21x24.21) surface mount packaging to ensure PCB footprint and mounting compatibility without redesign.

Manufacturer Continuity: Renesas Electronics Corporation maintains the 7005 series product line, ensuring design consistency and supply chain reliability.

The identified substitute part 7005L15JG meets all these criteria while offering active product status and enhanced performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The 7005L15JG is the direct active equivalent for the obsolete 7005SJ based on the following engineering criteria:

Functional Equivalence: Both parts share identical memory capacity (64Kbit), organization (8K x 8), architecture (dual port asynchronous SRAM), and parallel interface configuration. Pin-for-pin compatibility is maintained through identical 68-PLCC packaging.

Product Status: The 7005L15JG holds active product status with Renesas Electronics Corporation, ensuring long-term availability and supply chain continuity. The 7005SJ obsolete status creates procurement risk and supply uncertainty.

Regulatory Compliance: The 7005L15JG is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for new designs and procurement. Moisture sensitivity level 3 (168 hours) is documented for proper handling and storage protocols.

Performance Enhancement: The 7005L15JG provides specified access time and write cycle time of 15 ns with defined supply voltage range (4.5V ~ 5.5V) and operating temperature range (0°C ~ 70°C), enabling precise system timing calculations and thermal management planning.

Frequently Asked Questions (FAQ)

Q: Can the 7005L15JG directly replace the 7005SJ without PCB modifications?

A: Yes. Both parts use identical 68-PLCC (24.21x24.21) surface mount packaging with 68-LCC J-lead configuration. PCB footprint and mounting compatibility are maintained without design changes.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution requires equivalence in memory capacity (64Kbit), organization (8K x 8), dual port asynchronous architecture, parallel interface, and 68-PLCC package format. The 7005L15JG meets all these criteria.

Q: Does the 7005L15JG provide performance improvements over the 7005SJ?

A: The 7005L15JG specifies 15 ns access time and write cycle time with defined voltage (4.5V ~ 5.5V) and temperature (0°C ~ 70°C) parameters. The 7005SJ does not provide these specifications, making the 7005L15JG suitable for applications with defined timing requirements.

Q: Are there compliance differences between the two parts?

A: The 7005L15JG is ROHS3 compliant and REACH unaffected with documented moisture sensitivity level 3 (168 hours). The 7005SJ compliance status is not specified. Current procurement standards favor the 7005L15JG for regulatory alignment.

Q: What is the inventory status for the substitute part?

A: The 7005L15JG has 1087 pieces of new original stock available, compared to 1077 pieces for the obsolete 7005SJ. Active product status ensures ongoing availability.

Q: Are there secondary substitute options if 7005L15JG becomes unavailable?

A: The 7005L15JG lists 7005L20JGI as a further substitute option. Verification of compatibility parameters with 7005L20JGI should be performed based on the same substitution criteria: memory capacity, organization, architecture, interface, and packaging equivalence.
