Renesas Electronics 7005L25G SRAM Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 7005L25G is a 64Kbit dual-port asynchronous SRAM memory IC in a 68-PGA package with 25 ns access time. This component is classified as Last Time Buy, indicating discontinued production with limited inventory availability. Finding equivalent or substitute parts is necessary for ongoing system support, design refresh cycles, and long-term supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7005L25G is determined by the following critical parameters:

• Memory capacity (64Kbit) and organization (8K x 8)
• Dual-port asynchronous SRAM architecture
• Parallel memory interface
• 68-PGA package footprint and through-hole mounting
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (0°C ~ 70°C)

The 7005L35G qualifies as a direct substitute based on matching all mechanical and electrical parameters. The primary difference is access time and write cycle time specification: 35 ns versus 25 ns. This represents a relaxed timing specification, making the 7005L35G suitable for applications where the 25 ns performance is not a hard requirement.

Parameter Comparison

Engineering Selection Recommendations

The 7005L35G is the qualified substitute for the 7005L25G based on the following criteria:

• Identical memory capacity, organization, and dual-port asynchronous architecture
• Identical package footprint and through-hole mounting compatibility
• Matching supply voltage and operating temperature specifications
• Active product status, ensuring ongoing availability and supply chain stability
• Equivalent regulatory compliance (RoHS non-compliant, REACH Unaffected)

The timing difference (35 ns versus 25 ns) represents the only functional distinction. Selection of the 7005L35G is appropriate for applications where system timing margins accommodate the slower access and write cycle times. For timing-critical applications requiring 25 ns performance, the 7005L35G is not suitable.

Frequently Asked Questions (FAQ)

Q: Can the 7005L35G directly replace the 7005L25G in existing designs?

A: Direct replacement is possible from a mechanical and electrical standpoint. The 68-PGA package footprint, pinout, supply voltage, and operating temperature range are identical. However, the 35 ns access time must be compatible with system timing requirements. If the original design depends on 25 ns performance, the 7005L35G may not meet timing specifications.

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

A: The access time and write cycle time differ: 7005L25G operates at 25 ns, while 7005L35G operates at 35 ns. Both parts are 64Kbit dual-port asynchronous SRAM devices with identical memory organization and package specifications.

Q: Why is the 7005L25G marked as Last Time Buy?

A: Last Time Buy status indicates that Renesas Electronics has discontinued production of this part. Existing inventory is available for purchase, but no future production is planned. The 7005L35G, with Active status, represents the ongoing product line alternative.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share identical RoHS and REACH compliance status. Neither part is RoHS compliant, and both are REACH Unaffected. Regulatory considerations do not differentiate these parts.

Q: What should be verified before substituting the 7005L35G?

A: System timing analysis is required to confirm that 35 ns access and write cycle times are acceptable for the application. PCB layout and signal integrity considerations remain unchanged due to identical package specifications. No other verification is necessary from an electrical or mechanical perspective.
