72V243L7-5BCI

FIFOs Memory Overview

The Renesas 72V243L7-5BCI is a Super Sync II synchronous FIFO memory device. It features an 8K x 9 or 4K x 18 configuration with First Word Fall Through (FWFT) support. The component operates at a maximum clock frequency of 133.3 MHz and provides a typical access time of 5 ns. It functions on a single 3.3 V power supply and utilizes a 100-pin CABGA package.

FIFOs Memory Feature Summary

• Super Sync II technology enables simultaneous read and write operations without wait states.
• First Word Fall Through (FWFT) functionality allows immediate data availability upon address match.
• Supports bidirectional bus direction control for flexible system integration.

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between asynchronous logic domains
• Data acquisition systems requiring precise timing alignment

FIFOs Memory Procurement Notes

Verify the specific suffix 'L7' against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the 72V series. Confirm RoHS compliance status directly with the manufacturer, as older batches may differ from current production standards. Ensure ESD handling protocols are followed during installation due to CMOS sensitivity.

FIFOs Memory Selection Notes

Select this component when low-latency synchronization between different clock domains is required. The 5 ns access time suits high-performance applications. Consider the 100-CABGA package constraints for PCB layout. Verify that the 3.3 V operating voltage aligns with the target system's power rails before finalizing the design.

FIFOs Memory Part Context

This part belongs to the Renesas 72V253/72V243 family of Super Sync II FIFOs. These devices are designed for high-speed data transfer applications where deterministic latency is critical. The family offers various depth and width configurations to accommodate different data path requirements in industrial and communication systems.

FIFOs Memory Replacement Considerations

Check for direct cross-reference part numbers such as IDT72V243L7-5BCI. Verify pin compatibility and electrical specifications before substitution. Note that some variants may have different suffix codes indicating package or temperature range changes.
