7130SA55PFI8

Memory IC Overview

The Renesas Electronics Corporation 7130SA55PFI8 is an asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 8 kbit organized as 1K x 8 bits. The component supports parallel interface communication with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum power supply current of 110 mA. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm. It is designed for commercial temperature operation ranging from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location by two separate ports.
• Asynchronous operation allowing flexible timing control for both read and write cycles without clock synchronization.
• Integrated port arbitration logic to manage data conflicts during concurrent access attempts.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid sequential writes

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper handling procedures are followed given the surface-mount package type. Validate that the specific suffix corresponds to the required packaging format for your production line.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. Consider the 55 ns access speed against system timing requirements. Evaluate the TQFP-64 footprint compatibility with existing PCB layouts. Assess thermal management needs based on the specified operating temperature range and power dissipation characteristics.
