7204L15SOGI8

Overview

The Renesas Electronics Corporation 7204L15SOGI8 is an asynchronous FIFO memory device featuring a 4K x 9 organization and 36.86 kbit storage capacity. It operates with a maximum clock frequency of 40 MHz and a typical access time of 15 ns. The component supports bidirectional data buses and functions within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum supply current of 120 mA. Designed for industrial environments, it maintains reliable performance across an operating temperature range from -40°C to +85°C. The integrated circuit is housed in a 28-SOIC package.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface integration.
• Bidirectional data bus architecture supports versatile system connectivity requirements.
• Industrial-grade thermal stability ensures consistent functionality across wide temperature variations.

Applications

• Buffering data streams between disparate clock domains in embedded systems
• Data acquisition interfaces requiring temporary storage before processing
• High-speed serial-to-parallel conversion stages in communication equipment

Procurement Notes

Verify the specific suffix GI against official Renesas documentation to confirm package dimensions and marking details. Ensure compatibility with existing board layouts by cross-referencing the 28-SOIC footprint specifications. Confirm RoHS compliance status matches project requirements prior to ordering. Validate that the 4.5V to 5.5V supply range aligns with the target system power design.

Selection Notes

Select this component when asynchronous buffering with a 4K depth and 9-bit width is required. The 15ns access time suits applications needing moderate throughput without complex synchronization logic. Consider the 28-SOIC package for surface-mount assembly constraints. Evaluate the 120mA current consumption against total system power budgets to ensure adequate thermal management.

Part Context

This part belongs to the Renesas 7204 series of asynchronous FIFO memories, designed for high-performance data buffering. The series offers various configurations to accommodate different memory depths and bus widths. The 7204L15 variant specifically targets applications requiring fast access times and robust industrial reliability. It serves as a critical interface element in systems managing data flow between mismatched speed domains.

Replacement Considerations

Consult official Renesas documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when evaluating alternatives. Ensure any replacement maintains the same asynchronous timing and voltage specifications.
