7203LA12JG

Overview

The Renesas Electronics Corporation 7203LA12JG is an asynchronous FIFO memory device with a density of 512 x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 12 ns. The component is housed in a PLCC-32 package and supports CMOS parallel interface technology.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• CMOS parallel interface architecture
• Standard TTL-compatible I/O levels

Applications

• Data buffering between different clock domains
• Interface bridging in digital logic systems
• Temporary data storage in high-speed processing chains

Procurement Notes

Verify the specific suffix 'JG' against official Renesas documentation to confirm package type and moisture sensitivity level. Ensure compatibility with existing PCB footprints for PLCC-32 components. Confirm RoHS compliance status as manufacturing practices may vary by production date.

Selection Notes

Select this part when a small-capacity, low-latency buffer is required for 9-bit wide data paths. The 12 ns access time suits moderate-speed applications. Verify that the 512-word depth meets system requirements compared to larger capacity alternatives like the 2K or 4K variants in the same series.

Part Context

This component belongs to the Renesas 7201L/7203L family of asynchronous FIFOs. It shares architectural similarities with other members but differs in memory organization and speed grades. The 7201L designation typically indicates the 512x9 configuration within this product line.
