7130SA45JI8

Memory IC Overview

The Renesas Electronics Corporation 7130SA45JI8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time of 25 nanoseconds. It operates on a single 4.5V to 5.5V power supply and supports surface-mount installation in a 52-lead Plastic Leadless Chip Carrier package measuring 19.13mm by 19.13mm. The component is rated for an ambient operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent, simultaneous asynchronous read and write operations via separate control, address, and data pins.
• Asynchronous operation allows flexible timing requirements without reliance on a global clock signal for either port.
• Integrated automatic power-down functionality reduces standby power consumption when chip enable signals are inactive.

Memory IC Applications

• High-speed data buffering in industrial automation systems requiring low-latency memory access.
• Real-time processing units in telecommunications equipment needing concurrent data handling.
• Embedded control modules in automotive electronics where independent port access improves system throughput.

Memory IC Procurement Notes

Verify the exact suffix designation against official manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status as older variants may not meet current environmental directives. Check for obsolescence notices or last-time-buy dates before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 52-PLCC package. Validate voltage levels match system requirements strictly within the specified operational range.

Memory IC Selection Notes

Select this component when independent dual-port access is required for high-speed data exchange between processors. The 25ns access speed suits applications demanding rapid response times. Verify that the 5.5V maximum supply voltage aligns with the target system's power rails. Consider the 52-PLCC package dimensions for adequate board space allocation. Assess thermal management needs given the specified operating temperature limits.
