7132SA25JI8

Overview

The Renesas 7132SA25JI8 is a dual-port static random-access memory (SRAM) integrated circuit with a storage capacity of 16 kbit, organized as 2K x 8. It features an asynchronous parallel interface with a maximum access time of 25 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 52-PLCC package. It is designed for commercial temperature environments ranging from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array by two separate masters.

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications requiring concurrent read/write operations

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental directives. Validate package integrity upon receipt to ensure pin alignment matches the 52-PLCC specification before integration into assembly processes.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access without external arbitration logic. Ensure system design accommodates the 52-PLCC surface-mount footprint and 4.5V to 5.5V power supply constraints. Verify that the commercial temperature range meets operational environmental requirements.

Part Context

This part belongs to the Renesas 7132 series of dual-port SRAMs, which provide high-speed non-volatile-like performance with volatile retention. The series is characterized by asynchronous operation and parallel interfaces, targeting applications needing fast data interchange between processing elements.
