7008S55PFI8

Memory IC Overview

The Renesas Electronics Corporation 7008S55PFI8 is a high-speed dual-port static random-access memory (SRAM) IC. It features a storage capacity of 512Kb, organized as 64K words by 8 bits. The device utilizes a parallel interface with an access time and write cycle time of 55 ns. It operates on a single 5V power supply within the range of 4.5V to 5.5V. The component is housed in a 100-pin TQFP package measuring 14x14 mm. It supports surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent reads from both ports.
• On-chip hardware support for semaphore signaling between ports.
• Automatic power-down feature controlled by chip enable for low standby power.
• TTL-compatible single 5V power supply operation.

Memory IC Applications

• Stand-alone 512k-bit dual-port RAM systems
• Master/slave dual-port RAM configurations for 16-bit or wider data buses
• High-speed data buffering applications

Memory IC Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm industrial temperature rating and RoHS compliance status. Confirm package dimensions match the 100-TQFP specification. Check current product lifecycle status as some variants may be discontinued. Ensure voltage requirements align with system design constraints.

Memory IC Selection Notes

Select this component when a 512Kb dual-port SRAM with 55 ns speed is required. Choose the 100-TQFP package for surface-mount assembly needs. Consider the 7008L series if an extended industrial temperature range (-40°C to +85°C) is necessary instead of the commercial range.

Memory IC Part Context

The 7008S55PFI8 belongs to the Renesas 7008S family of high-speed dual-port SRAMs. This family is designed for applications requiring simultaneous access to shared memory locations. The part integrates port arbitration logic and interrupt flags to manage data integrity between two independent processors or controllers.

Memory IC Replacement Considerations

Check for direct pin-to-pin replacements within the 7008S series with different speed grades or packages. Verify compatibility with alternative manufacturers offering similar dual-port SRAM architectures.
