7008L55PFI8

Memory IC Overview

The 7008L55PFI8 is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device features parallel interface access 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 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate systems
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Parallel data interface supporting standard 8-bit word width connectivity

Memory IC Applications

• Data buffering between asynchronous logic subsystems
• Cache memory implementation in embedded processing units
• Temporary storage for high-speed data acquisition systems

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as older variants may not meet current environmental standards. Validate package integrity upon receipt, ensuring no pin damage or moisture exposure occurred during transit. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before final procurement commitment.

Memory IC Selection Notes

Select this component when dual independent access ports are required for asynchronous data handling. Ensure the system power supply remains stable within the 4.5V to 5.5V operating range to maintain signal integrity. Verify that the 100-TQFP footprint matches the printed circuit board layout constraints. Consider thermal dissipation requirements if multiple units operate at maximum load conditions simultaneously.

Memory IC Part Context

This part belongs to the 7008L series of dual-port SRAMs from Renesas, designed for applications requiring high-speed, non-volatile-like temporary storage with independent read/write capabilities. The series typically offers various speed grades and package options to suit different performance and space requirements in industrial and consumer electronics.

Memory IC Replacement Considerations

IDT7008L55PFI8 serves as a direct functional equivalent under the Integrated Device Technology brand, which was acquired by Renesas. Verify pinout compatibility and electrical parameter alignment before substitution.
