7025S20G

Memory IC Overview

The Renesas Electronics Corporation 7025S20G is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kbit, organized as 8K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 20 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 measuring 27.94 x 27.94 mm. The component is designed for through-hole installation and supports single data rate operations.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems.

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded controllers
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify the current lifecycle status before integration, as this specific part number is listed as obsolete and no longer manufactured. Confirm that the 84-PGA through-hole package is compatible with existing PCB footprints and assembly processes. Ensure that the 4.5V to 5.5V operating voltage aligns with the target system's power rails. Check for RoHS compliance requirements against the specific manufacturing batch documentation.

Memory IC Selection Notes

Select this component when a dual-port SRAM solution with 128 kbit capacity and 20 ns speed is required for through-hole designs. Compare against the 7025L series for surface-mount alternatives or different temperature grades. Evaluate the 84-PGA package constraints against available board space and mounting techniques. Consider the asynchronous interface compatibility with the host microcontroller or processor bus timing requirements.

Memory IC Part Context

This device belongs to the 7025 family of dual-port SRAMs produced by Renesas Electronics. It shares architectural similarities with other members like the 7025L20G but differs in packaging and thermal specifications. The 7025S20G specifically targets industrial or commercial environments using through-hole technology, distinguishing it from the surface-mount variants within the same performance class.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT7025S20G.
