7132SA100JI8

Overview

The Renesas Electronics Corporation 7132SA100JI8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features a parallel interface with a maximum access time of 100 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-pin PLCC package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems
• Asynchronous operation allowing flexible timing control without a global clock signal
• CMOS technology providing low power consumption relative to older bipolar SRAM implementations

Applications

• High-speed data buffering between disparate system components
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against project specifications, as this specific variant may not meet current environmental directives. Validate pin compatibility and electrical parameters against existing design schematics before integration into new hardware platforms.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Ensure the design accommodates the 52-PLCC footprint and 4.5V to 5.5V power supply constraints. Consider the 100ns access speed against system timing requirements and evaluate alternative packages if lead-free soldering processes are mandatory.
