7008S55PFI

Memory IC Overview

The Renesas 7008S55PFI is a dual-port asynchronous SRAM IC with a total storage capacity of 512Kb, organized as 64K words by 8 bits. It features a parallel interface and supports a supply voltage range of 4.5V to 5.5V. The device guarantees an access time and write cycle time of 55 ns. It operates within a commercial temperature range of 0°C to 70°C and is housed in a 100-TQFP (14x14) surface-mount package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on two separate ports.

Memory IC Applications

• Parallel data buffering in high-speed digital systems
• Cache memory implementation for microprocessors
• FIFO buffer applications requiring independent port access

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility and thermal characteristics against design specifications before integration into new hardware platforms.

Memory IC Selection Notes

Select this component when independent dual-port access is required for 512Kb parallel memory. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the 55 ns speed limit for timing constraints and verify that the 100-TQFP package fits the available PCB footprint.

Memory IC Part Context
