7134LA20P

Memory IC Overview

The Renesas Electronics Corporation 7134LA20P is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 4k words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 48-pin PDIP package. The component functions reliably across an operating temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors or systems
• Asynchronous parallel interface supporting standard logic-level control signals
• CMOS technology providing low power consumption relative to bipolar alternatives

Memory IC Applications

• Buffering data between high-speed processors and slower peripheral buses
• Implementing shared memory spaces in multi-processor embedded systems
• Providing temporary data storage in telecommunications equipment interfaces

Memory IC Procurement Notes

Verify the specific suffix designation against official manufacturer documentation, as package variations exist within this series. Confirm RoHS compliance status and moisture sensitivity levels prior to integration into assembly processes. Ensure that the selected variant matches the required pinout and thermal specifications for the target application environment.

Memory IC Selection Notes

Select this component when a non-volatile-free, high-speed buffer is required for bidirectional data exchange. Evaluate the 20 ns access speed against system timing requirements to ensure compatibility with the driving logic. Consider the 48-pin through-hole package constraints regarding PCB layout density and mechanical mounting stability during selection.

Memory IC Part Context

This part belongs to the 7134LA family of dual-port SRAMs manufactured by Renesas Electronics. The family shares common architectural features but varies in access speed and physical packaging. This specific model represents the 20 ns speed grade within the commercial temperature range segment, distinct from industrial or military variants found in the broader product line.
