7006S55PFI8

Overview

The Renesas 7006S55PFI8 is a dual-port asynchronous SRAM IC with a storage capacity of 128Kb (16K x 8). It features a parallel interface and a typical access time of 55 ns. The device operates on a supply voltage ranging from 4.5V to 5.5V and supports surface mount installation in a 64-TQFP (14x14) package. It functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation for flexible system integration without clock synchronization requirements
• Parallel interface supporting high-speed data transfer

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded controllers
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any functional updates or environmental compliance changes before final design integration.

Selection Notes

Select this component when dual independent port access is required for 128Kb memory. Ensure system voltage aligns with the 4.5V to 5.5V specification. Consider the 64-TQFP footprint constraints during PCB layout planning.
