7201LA12SOG8

Overview

The Renesas Electronics Corporation 7201LA12SOG8 is an asynchronous FIFO memory integrated circuit housed in a 28-SOIC surface-mount package. It provides a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 50MHz and features a typical access time of 12ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. The component is designed for industrial applications with an operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface bridging.
• Unidirectional bus architecture simplifies system design for specific data flow requirements.
• Integrated retransmit capability ensures data integrity during bus contention or error conditions.

Applications

• Buffering data streams between components operating at different clock speeds
• Interface adaptation in high-speed digital signal processing systems
• Data buffering in telecommunications equipment requiring reliable temporary storage

Procurement Notes

Verify the complete part number including suffixes to ensure correct package type and temperature rating. Confirm RoHS3 compliance status for environmental regulations. Check moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Validate that the 28-SOIC footprint matches the target PCB layout specifications before ordering.

Selection Notes

Select this component when a 512x9 word depth is required for asynchronous buffering. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 12ns access time against system timing constraints. Verify that unidirectional data flow meets application needs rather than bidirectional alternatives.

Part Context

This part belongs to the Renesas 7201L series of CMOS parallel FIFO memories. The series offers various speed grades and packaging options to suit different performance and form factor requirements. The 7201LA12 variant specifically targets applications needing 12ns access times within the standard SOIC package configuration.

Replacement Considerations

Check for IDT7201LA12SOG8 as a potential equivalent identifier from prior branding eras. Verify pin compatibility and electrical parameters if substituting with other 7201L series members like the 7201LA15SOGI8, noting differences in speed and temperature range.
