7201LA12TPG

Overview

The Renesas Electronics Corporation 7201LA12TPG is an asynchronous FIFO memory device featuring a storage capacity of 4.5K bits, organized as 512 words by 9 bits. It operates with a maximum data rate of 50MHz and provides an access time of 12ns. The component supports unidirectional bus direction and includes relay capability. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 80mA. Designed for surface-mount or through-hole applications depending on the package variant, it operates reliably across a 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 data flow management in specific application architectures.
• Relay capability enables signal buffering and isolation between different system segments.

Applications

• Data buffering in high-speed digital communication interfaces
• Clock domain crossing in mixed-frequency circuit designs
• Temporary data storage in embedded processing systems

Procurement Notes

Verify the exact package type upon ordering, as the model suffix indicates a 28-PDIP through-hole configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process specifications. Ensure the supplier provides official datasheets to validate the 12ns access time and 50MHz operational limits. Check for any recent product change notifications that might affect marking or assembly details before finalizing procurement.

Selection Notes

Select this component when a 512x9 word depth is required for asynchronous data buffering. The 12ns access time suits moderate-speed applications up to 50MHz. Consider the 28-PDIP package only if through-hole mounting is necessary for mechanical stability. Compare against other 7201 series variants if bidirectional data transfer or different access speeds are needed. Ensure the 4.5V to 5.5V supply voltage aligns with your system's power rails.
