7204LA12JG

Overview

The Renesas Electronics Corporation 7204LA12JG is an asynchronous FIFO memory device belonging to the 7204L series. It features a storage capacity of 36K bits, organized as 4K words by 9 bits. The component supports unidirectional data transfer with a maximum clock frequency of 50MHz and a typical access time of 12ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 120mA. The device is housed in a 32-PLCC package and is designed for surface-mount installation.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface bridging.
• CMOS parallel architecture provides high-speed data throughput suitable for buffering applications.
• Unidirectional bus direction simplifies control logic design for specific data flow requirements.

Applications

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

Procurement Notes

Verify the exact suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required pinouts and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level prior to PCB assembly planning. Cross-reference part number aliases such as IDT7204LA12JG to identify equivalent sourcing options from authorized distributors.

Selection Notes

Select this component when a 4Kx9 asynchronous FIFO with 12ns access time is required. Ensure the application supports unidirectional data flow and operates within the specified 4.5V to 5.5V voltage range. Consider the 32-PLCC package constraints for board layout and thermal management during the design phase.
