72V243L6BC

FIFOs Memory Overview

The Renesas Electronics Corporation 72V243L6BC is a high-speed synchronous FIFO memory device belonging to the 72V series. It provides a total memory capacity of 36K bits, configurable as 2K x 18 or 4K x 9. The component supports a maximum data rate of 166MHz with an access time of 4ns. It operates on a single 3.3V supply voltage ranging from 3.15 V to 3.45 V. The device features uni-directional data flow and is housed in a 100-CABGA package.

FIFOs Memory Feature Summary

• Uni-directional synchronous FIFO architecture for efficient data buffering
• Configurable bus width supporting both 18-bit and 9-bit data paths
• High-speed operation capability up to 166MHz with 4ns access time
• Supports First Word Fall Through (FWFT) functionality

FIFOs Memory Applications

• Data buffering between asynchronous clock domains
• Interface bridging in high-speed digital systems
• Temporary storage in communication protocol converters

FIFOs Memory Procurement Notes

Verify component status carefully as this part may be obsolete. Confirm RoHS compliance requirements against project specifications. Check moisture sensitivity level handling procedures during assembly. Ensure pin compatibility with existing PCB footprints before procurement.

FIFOs Memory Selection Notes

Select this component when a uni-directional synchronous FIFO with 3.3V logic levels is required. Consider the 100-CABGA package constraints for board layout. Evaluate if the 36K bit depth meets system buffer requirements. Verify that the 166MHz speed matches the target application timing.

FIFOs Memory Part Context

This device is part of the Renesas 72V series of SuperSync II FIFOs. It shares architectural similarities with other members like the 72V253L6BC but differs in memory depth. The series is designed for high-performance data buffering applications requiring precise synchronization.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The 72V253L6BC is a related model with different memory depth. Verify functional equivalence with alternative suppliers if sourcing is restricted.
