7132L55PDGI

Memory IC Overview

The Renesas Electronics Corporation 7132L55PDGI is a 16Kbit dual-port asynchronous SRAM IC. It features a memory organization of 2K x 8 bits and supports parallel interface communication. The device offers a maximum access time of 55 ns with a write cycle time of 55 ns. It operates within a supply voltage range of 4.5V to 5.5V and is designed for surface mount installation in a 48-PDIP package. The component functions reliably across an operating temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation allowing flexible timing integration without clock synchronization
• Parallel interface supporting standard data bus connections for high-speed data transfer

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring rapid read/write cycles

Memory IC Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply. Confirm RoHS compliance requirements against specific project standards, noting that older revisions may not meet current environmental regulations. Ensure the 48-PDIP package dimensions match the target PCB footprint design constraints before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access to shared memory resources. The 55 ns speed class suits applications needing moderate latency without the complexity of synchronous interfaces. Consider the 48-PDIP package if through-hole mounting is preferred for mechanical stability or prototyping environments over surface-mount alternatives.

Memory IC Part Context

This part belongs to the 7132 series of dual-port SRAMs from Renesas. These devices are engineered for applications requiring independent port access. The 7132L55PDGI specifically denotes the 55 ns speed grade and PDIP packaging variant within this family, providing a robust solution for legacy system upgrades or specialized industrial designs.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades such as the 7132LA25PFGI if faster performance is needed. Verify package compatibility when substituting with other 48-pin DIP variants. Ensure electrical specifications like voltage ranges and access times align with existing circuit designs to prevent signal integrity issues.
