7130SA45JI

Memory IC Overview

The Renesas Electronics Corporation 7130SA45JI is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits organized as 1K by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 25 nanoseconds. It operates on a single 5-volt power supply within the range of 4.5 to 5.5 volts. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface mount installation. The specified operating temperature range extends from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports
• Provides high-speed data transfer with a 25 nanosecond access time
• Operates reliably across an extended industrial temperature range

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded controllers
• Data storage in industrial automation equipment

Memory IC Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations such as JI or I8 may indicate specific packaging or testing configurations. Confirm RoHS compliance status, as older variants often lack lead-free certification. Check current product lifecycle status, as this series is frequently discontinued. Ensure the selected package matches the target PCB footprint dimensions precisely.

Memory IC Selection Notes

Select this component when a design requires true dual-port functionality for concurrent processor and peripheral access. The 25 nanosecond speed rating suits applications demanding rapid data throughput. Verify that the system voltage aligns with the 4.5 to 5.5 volt specification. Consider the 52-lead PLCC package constraints regarding board space and thermal management requirements during the layout phase.

Memory IC Part Context

This part belongs to the 7130SA/LA family of dual-port SRAMs manufactured by Renesas Electronics. The family shares architectural similarities with other members like the 7133SA and 7140LA series, differing primarily in bit organization and speed grades. These devices are engineered for robust performance in environments requiring reliable, non-volatile-like temporary storage without the complexity of synchronous clocking.
