7133LA70GB

Overview

The Renesas Electronics Corporation 7133LA70GB is a CMOS dual-port static random-access memory (SRAM) device. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The component features an asynchronous parallel interface with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum power current of 250 mA. The device is housed in a 68-pin Plastic Grid Array (PGA-68) package designed for through-hole mounting. It is rated for an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array by two separate processors or systems.
• CMOS technology providing high-speed asynchronous operation with low power consumption characteristics.
• Extended temperature rating suitable for harsh industrial and military environments requiring reliability under extreme thermal conditions.

Applications

• Real-time data buffering in industrial control systems
• High-speed cache memory in embedded processing applications
• Data logging and temporary storage in aerospace instrumentation

Procurement Notes

Verify RoHS compliance status carefully, as this specific part number is listed as non-compliant in available documentation. Confirm the lead-free status and environmental declarations prior to integration into regulated assemblies. Check for active production status, as discontinuation notices may apply to legacy components in this series.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access without arbitration overhead. Ensure the design accommodates the PGA-68 through-hole footprint and the specified 4.5V to 5.5V power supply rails. Consider the -55°C to +125°C operating range if the application environment exceeds standard commercial limits.

Part Context

This device belongs to the 7133SA/LA series of high-performance dual-port SRAMs manufactured by Renesas Electronics. The 'LA' suffix typically denotes extended temperature ranges compared to standard commercial variants. These components are designed for applications requiring fast, independent read/write cycles from two distinct ports.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific component were not identified in the provided source material. Verify compatibility with alternative dual-port SRAMs based on pinout, voltage, and timing specifications.
