7130SA55TFI

Memory IC Overview

The 7130SA55TFI is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features parallel interface access with a maximum access time and write cycle time of 55 nanoseconds. It operates on a single 5-volt power supply ranging from 4.5 to 5.5 volts. The component is housed in a 64-lead thin quad flat package (TQFP) measuring 10x10 mm, designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate ports with dedicated address, data, and control lines.
• Utilizes CMOS technology to deliver high-speed asynchronous performance without requiring external clock synchronization.
• Integrates automatic power-down functionality controlled by chip enable signals to minimize standby current consumption.

Memory IC Applications

• Real-time data buffering in industrial automation systems
• High-speed cache memory in embedded controller architectures
• Data logging interfaces in telecommunications equipment

Memory IC Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations may indicate differences in packaging or temperature ratings. Confirm RoHS compliance status prior to integration, as older batches may not meet current environmental directives. Check for end-of-life notifications to ensure long-term supply availability for production runs.

Memory IC Selection Notes

Select this component when dual-port isolation is required to prevent bus contention between multiple processors. Ensure the design accommodates the 5-volt logic levels and 64-pin TQFP footprint. Consider thermal management requirements if operating near the upper limit of the commercial temperature range.

Memory IC Part Context

This part belongs to the 7130SA series of dual-port SRAMs, which are designed for applications requiring concurrent access from two masters. The series typically offers various access speeds and organizational configurations to suit different bandwidth needs within embedded systems.

Memory IC Replacement Considerations

Official substitutes include the IDT7130SA55TFI variant. Verify pin compatibility and electrical specifications before substitution.
