7130SA55TF

Memory IC Overview

The Renesas Electronics Corporation 7130SA55TF is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 64-pin Thin Quad Flat Package (TQFP). The component is rated for commercial operating temperatures between 0°C and +70°C.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations on two separate ports
• Utilizes CMOS technology for low power consumption
• Provides flexible parallel data bus interface

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data storage in industrial control equipment

Memory IC Procurement Notes

Verify the specific suffix 'TF' against official manufacturer documentation to confirm package dimensions and tape-and-reel specifications. Confirm RoHS compliance status, as older variants may not meet current environmental directives. Check for active discontinuation notices or production lifecycle changes before finalizing procurement plans.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. Ensure the design accommodates the 64-TQFP footprint and 55ns timing constraints. Verify that the system logic levels match the 4.5V to 5.5V supply requirements without additional level shifting.

Memory IC Part Context

This part belongs to the IDT/Renesas 7130SA series of dual-port SRAMs. It shares architectural similarities with other members like the 7130SA55C and 7130LA55TF, differing primarily in package type and temperature rating. The series is designed for applications requiring high-speed, non-volatile-like data retention during power cycles via battery backup.

Memory IC Replacement Considerations

Official upgrade alternatives include the 7130LA55TF for extended temperature ranges. Cross-reference pinouts and electrical characteristics carefully when substituting.
