7130SA55JT/R/C

Memory IC Overview

The Renesas Electronics Corporation 7130SA55JT/R/C is an asynchronous dual-port 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 and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package measuring 19.13mm x 19.13mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent read/write operations on separate ports
• Asynchronous operation for flexible system integration without clock synchronization requirements
• CMOS technology ensuring low power consumption relative to older bipolar alternatives

Memory IC Applications

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

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against project specifications, as this variant may not meet current environmental directives. Validate package integrity upon receipt, as PLCC components require careful handling to prevent lead damage during installation or inspection processes.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Ensure the 55ns speed meets system timing constraints. Verify that the 52-PLCC footprint aligns with existing PCB layouts. Consider the 4.5V to 5.5V operating range compatibility with the target system's power distribution network before finalizing the design choice.

Memory IC Part Context

This part belongs to the 7130SA series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 7130SA55C but differs in packaging and temperature rating. The series is designed for applications requiring high-speed, non-volatile-like retention characteristics without the complexity of synchronous interfaces.

Memory IC Replacement Considerations

Direct pin-to-pin replacements are limited due to the discontinued status. Evaluate equivalent parts from other manufacturers offering 8Kb dual-port SRAM in PLCC packages. Verify electrical parameter matching, specifically access times and voltage ranges, to ensure functional compatibility in existing designs.
