72T1845L6-7BB

FIFOs Memory Overview

The Renesas Electronics Corporation 72T1845L6-7BB is a high-performance TeraSync FIFO memory device designed for asynchronous and synchronous operation. It features a storage capacity of 36K bits, configurable as 2K x 18 or 4K x 9. The component supports data rates up to 83MHz in asynchronous mode and 200MHz in synchronous mode, with corresponding access times of 10ns and 3.6ns respectively. It operates within a supply voltage range of 2.375 V to 2.625 V and is housed in a 144-PBGA (13x13) package.

FIFOs Memory Feature Summary

• Supports both asynchronous and synchronous timing modes for flexible system integration
• Features First Word Fall Through (FWFT) capability for reduced latency
• Includes programmable flags and relay capabilities for advanced status monitoring
• Allows depth and width expansion for scalable memory configurations

FIFOs Memory Applications

• Network buffering applications requiring bus matching
• Video processing systems handling large data streams
• Telecommunications equipment needing high-speed data transfer
• Data communications interfaces with unequal bus sizes

FIFOs Memory Procurement Notes

Verify the specific suffix L6-7BB against official Renesas documentation to confirm pinout and electrical characteristics match your design requirements. Check current product lifecycle status as components may be subject to discontinuation notices. Ensure compatibility with RoHS regulations if required by your manufacturing standards. Confirm availability through authorized distributors only.

FIFOs Memory Selection Notes

Select this component when designing systems that require precise clock domain crossing between asynchronous and synchronous logic blocks. The dual-mode operation allows optimization for either low-latency throughput or standard buffered access. Consider the 144-pin BGA package constraints during PCB layout planning. Evaluate power consumption specifications against thermal management capabilities in the final enclosure design.

FIFOs Memory Part Context

This part belongs to the Renesas 72T series of TeraSync FIFO memories, which are engineered for high-density data buffering. The series is widely utilized in networking and telecommunications infrastructure where reliable data flow control is critical. These devices bridge speed mismatches between different system components, ensuring data integrity during high-volume transfers.

FIFOs Memory Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters carefully before replacing. Generic FIFO equivalents may not support the specific TeraSync interface or FWFT functionality.
