7201LA12SOG

Overview

The Renesas 7201LA12SOG is an asynchronous FIFO memory IC featuring a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It supports unidirectional data transfer with a maximum data rate of 50MHz and an access time of 12ns. The device operates on a supply voltage range of 4.5V to 5.5V, with a maximum supply current of 80mA. It is housed in a 28-SOIC package (0.345 inch width) designed for surface-mount installation. The component functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface bridging.
• Unidirectional bus direction simplifies system architecture for specific data flow requirements.
• Relay capability enables cascading multiple units to expand total memory depth without external logic.

Applications

• Data buffering between microprocessors and peripheral devices operating at different clock speeds.
• Interface bridging in communication systems requiring temporary data storage during protocol conversion.
• Digital signal processing pipelines where burst data handling prevents information loss.

Procurement Notes

Verify the exact suffix against official Renesas documentation, as 'SOG' may denote specific tape-and-reel packaging or regional variants. Confirm RoHS compliance status, as older batches may differ from current production runs. Ensure the supplier provides valid traceability documents matching the manufacturer's part number format. Cross-reference the datasheet revision date to guarantee compatibility with latest electrical specifications.

Selection Notes

Select this component when a 512x9 word asynchronous buffer is required with 12ns performance. Consider the 28-SOIC package constraints for PCB layout and thermal management. Evaluate if the 50MHz speed meets the system's timing requirements compared to faster alternatives. Verify that the 4.5V-5.5V supply range aligns with the target platform's power rails.

Part Context

This part belongs to the Renesas 7201L series of high-speed asynchronous FIFOs. The series offers various access times and package options to suit different design needs. The 7201LA variant specifically targets applications requiring reliable data buffering with moderate speed and standard CMOS logic levels.

Replacement Considerations

Publicly confirmed substitutes include the IDT7201LA12SOG8. Verify pinout and electrical parameter equivalence before substitution. Check for any changes in packaging or moisture sensitivity levels that might affect assembly processes.
