7025L25GB

Memory IC Overview

The Renesas Electronics Corporation 7025L25GB is a dual-port static random-access memory (SRAM) device with a total storage capacity of 128 kbit. The memory is organized as 8k words by 16 bits per word, supporting parallel asynchronous interfaces for independent read and write operations on each port. It features a maximum access time of 25 ns and operates within a supply voltage range of 4.5 V to 5.5 V. The component is housed in an 84-pin Plastic Grid Array (PGA) package designed for through-hole mounting. It supports standard single-data-rate (SDR) operation and functions reliably across an industrial temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory array via two separate ports.
• Asynchronous parallel interface allowing flexible integration into systems without strict clock synchronization requirements.
• Single power supply operation utilizing a standard 5V logic level compatible voltage range.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring concurrent data handling.
• Industrial control systems needing reliable temporary storage for process variables.
• Embedded computing modules where independent processor access to shared memory is required.

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates potential non-compliance depending on specific manufacturing batches or legacy stock. Confirm package authenticity and pin integrity upon receipt, as PGA packages are susceptible to bent pins during handling. Check for end-of-life notifications or discontinuation notices from the manufacturer before finalizing procurement plans to ensure long-term supply stability.

Memory IC Selection Notes

Select this component when dual-port functionality is mandatory for system architecture. Ensure the design accommodates the 84-pin PGA footprint and through-hole assembly constraints. Verify that the 25 ns access speed meets the timing requirements of the host processors. Consider thermal management capabilities within the specified 0°C to +70°C operating range for the intended application environment.

Memory IC Part Context

This part belongs to the Renesas 7025L series of dual-port SRAMs, which provides high-performance memory solutions for applications requiring fast, independent access. The series typically offers various access speeds and packaging options to suit different design needs. The 7025L25GB specifically targets designs requiring robust, asynchronous memory with dual-port capabilities in a through-hole compatible package.

Memory IC Replacement Considerations

Direct replacements may include other 7025L series variants with similar access times but different packages, such as the 7025L20JGI8 in PLCC or 7025L20PFGI in TQFP. Note that package changes require PCB redesign. Verify electrical compatibility and pinout similarities before substitution.
