7008L55PFI

Memory IC Overview

The Renesas Electronics Corporation 7008L55PFI is a dual-port static random access memory (SRAM) integrated circuit. It features an asynchronous parallel interface with a storage capacity of 512Kb, organized as 64K words by 8 bits. The device supports a supply voltage range of 4.5V to 5.5V and offers a maximum access time of 55 ns. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm and operates within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.
• Asynchronous operation allowing flexible timing integration without requiring a synchronized clock signal.
• Parallel data interface supporting standard byte-wide data transfer operations.

Memory IC Applications

• High-speed data buffering between processing units
• Cache memory implementation in embedded systems
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify the specific suffix PFI against official Renesas documentation to confirm package type and lead finish specifications. Confirm RoHS compliance status for current production lots. Check for end-of-life notices or obsolescence announcements prior to procurement. Ensure compatibility with existing board layouts regarding the 100-TQFP footprint.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Compare access times and power consumption against alternative SRAM families. Verify that the 5V supply requirement aligns with system voltage rails. Consider the TQFP package constraints for thermal management and PCB space availability.

Memory IC Part Context

This part belongs to the 7008L series of high-speed dual-port SRAMs manufactured by Renesas Electronics. The series typically includes variants with different access speeds and package options. These devices are designed for applications demanding high throughput and low latency in data handling scenarios.

Memory IC Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Identify parts with matching 512Kb capacity and dual-port architecture. Ensure replacement packages fit the existing 100-TQFP footprint without mechanical interference.
