7205L15J

Overview

The Renesas Electronics Corporation 7205L15J is an asynchronous FIFO memory device with a storage capacity of 36K bits, organized as 4K x 9. It features a unidirectional bus direction and operates at a maximum data rate of 40MHz with a 15ns access time. The component supports a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 120mA. It is housed in a 32-PLCC package (14x11.46) and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Asynchronous operation for flexible clock domain crossing
• Unidirectional data flow architecture
• CMOS parallel interface technology

Applications

• Data buffering between different clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist. Confirm RoHS compliance status, as older batches may differ. Check for End-of-Life notices or discontinuation announcements from Renesas. Ensure the specific package variant matches the design requirements. Validate humidity sensitivity levels for proper handling during assembly.

Selection Notes

Select this component when a 4K x 9 depth is required for unidirectional data transfer. Consider the 15ns access time for timing constraints. Evaluate the 4.5V to 5.5V supply requirement against system power rails. Compare the 32-PLCC package dimensions with available PCB space. Assess the -40°C to 85°C operating range against environmental conditions.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFOs. It shares architectural similarities with other members like the 7204L15JI but differs in organization and speed grades. The series is designed for general-purpose memory buffering applications requiring simple control logic and high throughput.
