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.
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
Applications
- High-speed data buffering in telecommunications equipment
- Cache memory implementation in embedded processing systems
- Data storage in industrial control applications
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.
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.
Part Context
This component belongs to the Renesas 7134SA series of dual-port SRAMs. It shares architectural similarities with other members like the 7134SA70J but differs in packaging format. The series targets applications requiring high-speed independent port access for complex data management tasks.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully when selecting alternative components from different manufacturers.
