7204L12JG

Overview

The Renesas Electronics 7204L12JG is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 36K bits, organized as 4K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 50 MHz with a 12 ns access time. The device utilizes a unidirectional bus architecture and is housed in a 32-PLCC surface-mount package measuring 14x11.46 mm. It functions reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface timing.
• Unidirectional data bus simplifies system design for single-direction data flow applications.
• CMOS technology ensures low power consumption while maintaining high-speed performance capabilities.

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary data storage in digital signal processing chains

Procurement Notes

Verify the specific suffix JG confirms the PLCC-32 package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process standards. Check current availability as lead times may vary. Ensure the unidirectional configuration matches your system architecture needs before finalizing procurement.

Selection Notes

Select this component when a 4K x 9 word depth is required for asynchronous buffering. The 12 ns access time suits moderate-speed digital interfaces. Consider the 32-PLCC package if through-hole or specific surface-mount footprint constraints apply. Verify that unidirectional data flow meets the application's directionality requirements compared to bidirectional alternatives.

Part Context

This part belongs to the Renesas 7204 series of asynchronous FIFO memories. It shares architectural similarities with other members like the 7204L15 variants but offers faster 12 ns access times compared to the 15 ns versions. The series provides standardized memory solutions for industrial and commercial electronic designs requiring reliable data staging.

Replacement Considerations

IDT7204L12JG serves as a direct equivalent part number from Integrated Device Technology. Cross-reference pinouts and electrical specifications to ensure compatibility during substitution. Verify package dimensions match existing PCB footprints when replacing components.
