7134SA70JI8

Memory IC Overview

The Renesas Electronics Corporation 7134SA70JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 4K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 70 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 52-pin PLCC package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation without requiring a system clock signal for data transfer
• CMOS technology construction providing low power consumption characteristics

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints and voltage levels before integration into new designs.

Memory IC Selection Notes

Evaluate the 70 ns access speed against system timing requirements. Consider the 52-PLCC package dimensions for board space constraints. Assess the 4.5 V to 5.5 V operating range against available power supplies. Review humidity sensitivity classifications for manufacturing process adjustments.
