7025S55JG

Memory IC Overview

The Renesas Electronics Corporation 7025S55JG is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kilobits organized as 8K words by 16 bits. The device features parallel interface access with a maximum access time of 55 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate ports without bus contention
• Includes on-chip hardware semaphore signaling logic for automatic port arbitration and synchronization
• Features automatic power-down mode controlled by chip enable signals to minimize standby current consumption

Memory IC Applications

• High-performance data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network routing infrastructure
• Real-time processing units in embedded computing architectures

Memory IC Procurement Notes

Verify the specific suffix designation against official documentation, as variations such as JG8 or JI8 indicate distinct packaging formats like tape-and-reel or tube. Confirm that the required operating temperature range aligns with the commercial specification, as industrial variants may carry different suffixes. Ensure compatibility with existing board layouts regarding the 84-PLCC footprint dimensions.

Memory IC Selection Notes

Select this component when a system requires true dual-port memory architecture allowing concurrent access from two independent processors. The 55ns speed rating suits applications where moderate latency is acceptable but simultaneous port operation is critical. Verify that the 8Kx16 organization matches the target data width requirements and that the PLCC package fits the available surface-mount constraints.

Memory IC Part Context

This part belongs to the Renesas 7025 series of dual-port SRAMs, which are engineered for standalone or master-slave configurations. The series supports expansion to wider data buses by connecting multiple devices. These components utilize CMOS technology to provide high-speed performance while maintaining low power consumption through dedicated power-down modes.
