7132SA25JI

Overview

The Renesas Electronics Corporation 7132SA25JI is a static random-access memory (SRAM) integrated circuit belonging to the 7132 series. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 52-PLCC package.

Feature Summary

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

Applications

• High-speed data buffering in embedded systems.

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements, as standard versions may not meet current environmental directives. Validate package integrity upon receipt to ensure pin alignment for PLCC sockets or adapters.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Ensure system design accommodates the 52-pin PLCC footprint and 5V logic levels. Consider thermal management within the specified operating temperature range during high-frequency operation.

Part Context

This part belongs to the Renesas 7132 family of dual-port SRAMs. These devices are designed for applications requiring high-speed data sharing between two independent masters without bus contention. The 7132SA25JI variant specifically denotes the 25 ns speed grade and industrial/commercial temperature options depending on suffix.

Replacement Considerations

Check for direct cross-references from IDT or other manufacturers offering equivalent 16Kb dual-port SRAMs in 52-PLCC packages. Verify pin compatibility and electrical specifications before substitution.
