7027S25G

Memory IC Overview

The Renesas Electronics Corporation 7027S25G is a high-speed, 512-kbit Dual-Port Static Random Access Memory (SRAM) organized as 32K words by 16 bits. It operates on a single 5.0V power supply with an access time of 25 nanoseconds. The device supports asynchronous parallel interfaces and features automatic power-down capabilities for low standby consumption. It is housed in a PGA-108 surface-mount package and is designed for use as a standalone dual-port RAM or in master/slave configurations.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two separate ports
• Automatic power-down feature allowing on-chip circuitry to enter very low standby power mode
• Asynchronous parallel interface compatible with standard TTL logic levels

Memory IC Applications

• Stand-alone 512K-bit dual-port memory systems
• Master/Slave dual-port RAM combinations for 32-bit or wider word systems
• High-speed data buffering between asynchronous components

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS compliance and specific package markings against official datasheets. Check for available lifecycle notifications regarding discontinuation or last-time-buy dates before finalizing procurement plans.

Memory IC Selection Notes

Select this component when dual independent port access is required for 16-bit wide data paths. Ensure the design accommodates the PGA-108 surface-mount footprint. Verify that the 5.0V operating voltage aligns with system power rails and that 25ns access speed meets timing requirements.

Memory IC Part Context

This part belongs to the Renesas 7027 series of high-speed dual-port SRAMs. These devices are engineered for applications requiring concurrent read/write operations from different controllers without bus contention, facilitating efficient data exchange in complex digital systems.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades within the 7027L series for improved temperature ranges. Verify if newer generation dual-port SRAMs offer equivalent density and speed with updated packaging options.
