7133SA45JI

Memory IC Overview

The Renesas Electronics Corporation 7133SA45JI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits organized as 2K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time and write cycle time of 45 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package measuring 24.21mm by 24.21mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation eliminating the need for external clock synchronization signals
• CMOS technology providing low power consumption characteristics relative to older bipolar technologies

Memory IC Applications

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

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the device may not meet current environmental standards. Validate package integrity upon receipt, as PLCC components are sensitive to mechanical stress during handling and soldering processes.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent bus access. Ensure system voltage levels remain within the specified 4.5V to 5.5V range. Consider the 68-PLCC footprint constraints during PCB layout design to ensure adequate clearance for thermal management and assembly tools.

Memory IC Part Context

This part belongs to the 7133SA family of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other variants in the series but differs in speed grade and packaging options. The 7133SA series is designed for applications requiring high-bandwidth memory access without complex synchronization protocols.

Memory IC Replacement Considerations

Official substitutes include the 7133SA45J and 7133SA45JI8. Verify pin compatibility and electrical specifications before substitution. Note that package variations such as PGA or TR may affect mechanical integration.
