7133LA70G

Overview

The Renesas Electronics Corporation 7133LA70G is a static random-access memory (SRAM) integrated circuit featuring a parallel interface. It provides a storage capacity of 32Kb, organized as 2K x 16 bits. The device operates with an access time of 70 ns and supports a supply voltage range of 4.5V to 5.5V. It is housed in a 68-pin PGA package designed for surface mount installation. The component functions as asynchronous dual-port SRAM and is classified as a non-volatile memory type within its specific operational context.

Feature Summary

• Supports simultaneous independent read and write operations through dual-port architecture
• Utilizes CMOS technology for efficient power consumption and high-speed data handling
• Provides flexible connectivity via a standard parallel interface

Applications

• High-performance embedded systems requiring fast data buffering
• Industrial control units needing reliable volatile memory storage
• Telecommunications equipment utilizing parallel data processing

Procurement Notes

Verify the exact suffix designation when sourcing replacements, as variations may indicate differences in temperature ranges or packaging standards. Confirm RoHS compliance status prior to integration, as older manufacturing runs may not meet current environmental regulations. Ensure the supplier provides valid traceability documentation for this discontinued component to maintain quality assurance protocols during procurement.

Selection Notes

Select this component when a 70 ns access speed meets system timing requirements without necessitating faster alternatives. The 68-PGA package is suitable for applications where through-hole mounting or specific footprint constraints are necessary. Consider the 2K x 16 organization for word-oriented data processing tasks that benefit from direct parallel bus interfacing capabilities.

Part Context

This part belongs to the 7133 series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other variants in the family, differing primarily in access speed and operating temperature specifications. The 70 ns variant represents a balance between performance and power efficiency for general-purpose industrial applications.

Replacement Considerations

The 7133SA70JI is listed as an upgrade substitute. Verify pin compatibility and electrical characteristics before implementation.
