7134LA45J8

Memory IC Overview

The Renesas Electronics Corporation 7134LA45J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 4096 words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-lead Plastic Leadless Chip Carrier (PLCC) package measuring 19.13mm by 19.13mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Memory IC Applications

• High-speed data buffering in industrial control systems
• Real-time data logging in embedded processing units
• Cache memory implementation in communication equipment

Memory IC Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations such as J, P, or CB indicate distinct physical packages and termination types. Confirm RoHS compliance status, as specific variants may not meet current environmental directives. Check discontinuation notices, as this product line has reached end-of-life status. Ensure compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this component when a non-volatile, high-speed memory solution with independent port access is required for synchronous data transfer applications. Consider the 45ns access speed and 32Kb capacity relative to system timing constraints. Evaluate the 52-PLCC package dimensions against available board space. Verify that the 4.5V to 5.5V supply range aligns with the target system's power distribution network.
