Renesas Electronics 7025L20G SRAM 128Kbit Parallel Memory - Equivalent & Substitute Parts

Part Overview

The Renesas Electronics 7025L20G is a dual-port asynchronous SRAM memory IC with 128Kbit capacity organized as 8K x 16, featuring a 20 ns access time and parallel interface in an 84-PGA package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The substitute parts listed maintain identical memory capacity, organization, and electrical specifications while offering different access time ratings and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7025L20G is determined by the following criteria, all of which must be maintained:

• Memory capacity: 128Kbit
• Memory organization: 8K x 16
• Memory technology: Dual-port asynchronous SRAM
• Parallel interface configuration
• Package type: 84-BPGA (27.94x27.94)
• Voltage supply range: 4.5V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C
• Mounting type: Through hole

The substitute parts differ only in access time (write cycle time) specifications. The 7025L20G operates at 20 ns; substitute parts are available at 25 ns, 35 ns, and 55 ns access times. All substitute parts maintain identical memory architecture, electrical characteristics, and physical packaging.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are manufactured by Renesas Electronics and maintain identical RoHS non-compliance status, MSL rating (1 - Unlimited), REACH unaffected status, and ECCN/HTSUS classifications as the original 7025L20G.

The 7025L25G provides the closest performance match to the 7025L20G with only a 5 ns increase in access time and is classified as an active product with substantial inventory availability.

The 7025S35G and both 7025L55G and 7025S55G variants are suitable for applications where the increased access time does not impact system timing requirements. These parts offer active product status and consistent availability.

Selection should be based on system timing constraints and the maximum acceptable access time for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 7025L25G directly replace the 7025L20G in existing designs?

A: The 7025L25G is electrically and mechanically compatible with the 7025L20G. The 5 ns increase in access time must be evaluated against system timing margins. If the original design operated with timing headroom, the 7025L25G functions as a direct substitute.

Q: What is the difference between the 7025L and 7025S series designations?

A: Both series maintain identical memory capacity, organization, voltage, temperature range, and package specifications. The series designation reflects internal Renesas product line categorization. Electrical and mechanical compatibility is maintained across both series at equivalent access time ratings.

Q: Are all substitute parts available in the same packaging format?

A: All listed substitute parts use the 84-BPGA (27.94x27.94) through-hole package. Physical footprint and mounting requirements are identical across all parts.

Q: What access time should be selected for a new design?

A: Access time selection depends on system clock frequency and timing budget. The 7025L20G specification of 20 ns supports the fastest operation. Slower access times (25 ns, 35 ns, 55 ns) are acceptable if system timing analysis confirms adequate margins.

Q: Are there compliance or certification differences between the main part and substitutes?

A: All parts share identical RoHS status (non-compliant), MSL rating (1), REACH status (unaffected), and trade classification codes. No compliance differentiation exists between the main part and substitute options.
