7006S55G

Overview

The Renesas Electronics Corporation 7006S55G is a dual-port static random access memory (SRAM) device with a storage capacity of 128 kbit, organized as 8K words by 16 bits. It features an asynchronous parallel interface with a maximum access time of 55 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a PGA-68 package. It is designed for industrial temperature ranges, functioning between -40°C and +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate ports
• Asynchronous operation without requiring a system clock signal
• Parallel data interface for direct connection to microprocessors or controllers

Applications

• Data buffering in high-speed communication systems
• Cache memory implementation in embedded processing units
• FIFO buffer applications in digital signal processing

Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding the PGA-68 footprint. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate electrical specifications against current design constraints before final procurement.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access operations. Consider the 55 ns access speed relative to system timing requirements. Evaluate the PGA-68 package suitability for automated surface-mount assembly processes. Compare power consumption characteristics against alternative SRAM families if low-power operation is critical. Verify that the 4.5 V to 5.5 V operating range aligns with the target system's power supply rails.

Part Context

This device belongs to the Renesas 7006 series of dual-port SRAMs, which are designed for applications requiring high-speed data sharing between two processors or logic blocks. The series offers various access speeds and packaging options to suit different performance and space constraints. These components are commonly used in telecommunications, networking equipment, and industrial control systems where reliable, fast memory access is essential.

Replacement Considerations

Check for direct pin-compatible replacements within the same Renesas family, such as other 7006 variants with different access times or packages. Verify functional equivalence with third-party dual-port SRAMs if sourcing alternatives. Ensure any substitute maintains the same 128 kbit capacity and 8Kx16 organization.
