7025L55G

Memory IC Overview

The Renesas Electronics Corporation 7025L55G is a dual-port static random-access memory (SRAM) device belonging to the 7025L series. It provides a total storage capacity of 128 kbit, organized as 8k words by 16 bits. The component features an asynchronous parallel interface with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in an 84-pin PGA package. This specific part number is designated as obsolete and has been discontinued by the manufacturer.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems.
• Asynchronous operation allowing flexible timing control without reliance on a global clock signal.
• Standard parallel interface supporting direct connection to microprocessors and digital logic circuits.

Memory IC Applications

• High-speed data buffering between asynchronous system components.
• Cache memory implementation in embedded processing architectures.
• FIFO buffer applications requiring independent read and write ports.

Memory IC Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Renesas Electronics. Verification of authenticity is critical when sourcing from secondary markets due to potential availability of refurbished units. Engineers should consult official discontinuation notices for detailed end-of-life timelines. Replacement strategies must prioritize verified compatible substitutes to ensure long-term project viability and supply chain stability.

Memory IC Selection Notes

Designers requiring this specific performance profile should evaluate current active alternatives within the 7025L family that offer faster access times or updated packaging options. Selection criteria must account for the transition from through-hole PGA packages to surface-mount technologies if board space is constrained. Compatibility checks regarding pin configurations and electrical specifications are essential when migrating to newer generation SRAM devices.

Memory IC Part Context

The 7025L55G is part of the broader 7025L series of dual-port SRAMs produced by Renesas Electronics. This series is characterized by its high-speed asynchronous operation and robust parallel interface capabilities. The 'L' suffix typically denotes specific speed grades and package variations within the product line, while the '55' indicates the 55 nanosecond access time specification.

Memory IC Replacement Considerations

Official documentation identifies the 7025L15PFG8 as a recommended upgrade substitute for this discontinued component.
