7132LA55PDG

Overview

The Renesas Electronics Corporation 7132LA55PDG is a static random-access memory (SRAM) integrated circuit featuring dual-port asynchronous architecture. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device utilizes CMOS technology and operates within a supply voltage range of 4.5V to 5.5V. Key electrical specifications include a maximum access time of 55 nanoseconds and a maximum power consumption of 325 milliwatts. The component is housed in a 48-pin Plastic Dual In-line Package (PDIP).

Feature Summary

• Dual-port asynchronous architecture enabling independent simultaneous access from two separate ports.
• Low-power CMOS fabrication designed for typical operation at 325mW.
• Parallel interface supporting standard synchronous and asynchronous read/write cycles.

Applications

• High-speed data buffering in telecommunications equipment.
• Cache memory implementation in embedded processing systems.
• FIFO buffer applications requiring independent port access.

Procurement Notes

Verify the specific package variant, as 'PDG' typically denotes PDIP but cross-reference with official Renesas documentation to confirm pinout and mechanical dimensions. Confirm RoHS compliance status, as older Renesas SRAM variants may not meet current environmental directives. Ensure the supplier provides valid traceability documents given the component's age and potential discontinuation status.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. Compare against single-port alternatives if only one access point is needed, as dual-port devices incur higher cost and power consumption. Verify that the 55ns access speed meets system timing requirements and that the 4.5V-5.5V voltage range aligns with the target logic family.

Part Context

This part belongs to the IDT 7132/7142 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various capacities and speeds, with the LA suffix indicating low-power consumption characteristics. These components are widely used in industrial and commercial applications requiring reliable, high-speed volatile memory with independent access capabilities.

Replacement Considerations

Official substitutes include other members of the 7132 series with compatible pinouts and electrical characteristics. Verify functional equivalence regarding access times and power dissipation before replacement. Note that some newer revisions may have different packaging options or updated compliance certifications.
