7132LA25C

Overview

The Renesas Electronics Corporation 7132LA25C is a 16Kbit (2K x 8) asynchronous dual-port static random-access memory (SRAM) IC. It features a parallel interface with a maximum access time of 25 ns and a write cycle time of 25 ns. The device operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 48-SIDE BRAZED package, designed for surface mount installation. The component supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation compatible with various system clock speeds
• CMOS technology providing low power consumption characteristics

Applications

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

Procurement Notes

Verify the specific package variant, as the 7132LA25C designation may refer to different physical packages such as the 48-SIDE BRAZED or standard DIP configurations depending on the manufacturer's revision history. Confirm RoHS compliance status, as older batches may not meet current environmental standards. Ensure the selected substitute matches the exact pinout and electrical specifications to guarantee compatibility with existing circuit designs.

Selection Notes

Select this component when a design requires independent read/write ports for concurrent processor access without bus contention. The 25 ns speed grade suits applications demanding moderate latency. Consider the 48-pin side-brazed package for robust surface-mount assembly requirements. Verify that the 4.5V to 5.5V supply range aligns with the system's power rails before integration into the final product architecture.

Part Context

This part belongs to the IDT/Renesas 7132SA/LA series of dual-port SRAMs. These components are widely used in legacy and specialized industrial designs requiring reliable, high-speed memory with dual-processor capabilities. The series offers various speed grades and package options to accommodate different performance and form-factor constraints in electronic systems.

Replacement Considerations

Direct substitutes include the 71321LA25PFGI and 71321LA25JI, which offer similar 16Kbit capacity and 25 ns speed but in different packages such as TQFP or PLCC. Verify pin compatibility and package dimensions before replacement.
