7008S20PFI8

Memory IC Overview

The 7008S20PFI8 is a dual-port 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 an asynchronous parallel interface with a maximum access time and write cycle time of 20 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. The component is rated for an ambient operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on both ports
• Asynchronous parallel interface supporting standard logic levels
• High-speed data access with 20 ns timing characteristics
• Industrial-grade temperature rating for reliable operation in harsh environments

Memory IC Applications

• Data buffering in high-performance computing systems
• Cache memory implementation in embedded controllers
• FIFO buffer applications in telecommunications equipment
• Real-time data acquisition systems requiring low latency

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Validate package integrity upon receipt, ensuring no pin damage occurred during handling. Check datasheet revisions for any labeling changes or parameter updates prior to final design integration.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Ensure the system voltage aligns with the 4.5V to 5.5V specification. Consider the 100-TQFP footprint for PCB layout constraints. Evaluate thermal management needs given the industrial temperature range. Compare against single-port alternatives if simultaneous access is unnecessary to reduce cost and complexity.

Memory IC Part Context

This part belongs to the 7008 series of dual-port SRAMs, designed for applications requiring fast, independent access from two different masters. The 'S' suffix typically denotes the specific package type and speed grade within the family. Renesas acquired this product line from Integrated Device Technology (IDT), maintaining continuity in specifications and pinouts for legacy designs.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, verify compatibility with equivalent dual-port SRAMs from other manufacturers, ensuring matching pinout, voltage, and timing parameters.
