7201LA12JG8

Overview

The Renesas Electronics Corporation 7201LA12JG8 is an asynchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The component supports unidirectional data bus direction and features a maximum data rate of 50MHz with an access time of 12ns. It operates within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 80mA. The device is housed in a 28-SOIC package (0.345 inch width) and is designed for surface mount installation. It functions reliably across a commercial operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface integration.
• Unidirectional bus architecture simplifies system design for specific data flow requirements.
• High-speed performance supports data rates up to 50MHz with 12ns access times.

Applications

• Buffering data streams between components operating at different clock speeds
• Interface bridging in high-speed digital communication systems
• Data acquisition systems requiring temporary storage before processing

Procurement Notes

Verify the exact suffix JG8 against official Renesas documentation to confirm the 28-SOIC surface-mount package configuration. Ensure compatibility with RoHS3 standards and MSL level 3 handling requirements during assembly. Confirm that the 4.5V to 5.5V supply voltage aligns with the target system power rails. Validate that the 50MHz speed grade meets the specific timing constraints of the application design.

Selection Notes

Select this component when a 512x9 word asynchronous FIFO is required with 12ns access speed. The 28-SOIC package is suitable for surface-mount applications needing a compact footprint. Consider the 80mA maximum current consumption for power budget calculations. Ensure the unidirectional bus direction matches the system's data flow topology. Verify that the 0°C to 70°C operating temperature range satisfies environmental conditions.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFO memories, which are CMOS parallel devices. The series offers various configurations and speed grades to support diverse memory buffering needs. The 7201LA12JG8 specifically addresses applications requiring moderate depth and high-speed data transfer capabilities within standard industrial temperature ranges.

Replacement Considerations

Consult official Renesas documentation for verified substitute part numbers. Cross-reference specifications such as access time, organization, and package type to ensure functional equivalence. Do not assume compatibility based on similar naming conventions without verifying electrical parameters.
