72205LB10J

Overview

The Renesas Electronics Corporation 72205LB10J is a synchronous First-In, First-Out (FIFO) memory device belonging to the 7200 series. It features a storage capacity of 1K x 18 bits and operates with a maximum data rate of 100MHz. The component supports unidirectional bus direction and includes programmable flags for status monitoring. It functions within a supply voltage range of 4.5 V to 5.5 V and is housed in a 68-PLCC package.

Feature Summary

• Synchronous FIFO architecture with clocked read and write controls
• Programmable full and empty flag outputs for buffer management
• Unidirectional data bus interface supporting 18-bit word width

Applications

• Data buffering in high-speed digital signal processing systems
• Interprocessor communication interfaces requiring precise timing control
• Network protocol handling where packet alignment is critical

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity level requirements during storage and handling. Validate package integrity upon receipt to ensure pin compatibility with existing PCB footprints.

Selection Notes

Select this component when designing systems requiring deterministic latency for 18-bit data streams. Ensure the host controller supports synchronous signaling compatible with the 100MHz specification. Verify that the 68-PLCC footprint matches the target board layout. Consider thermal dissipation characteristics if operating near maximum voltage limits.

Part Context

This part belongs to the Renesas 7200 series of high-performance FIFO memories. It shares architectural similarities with other members like the 72205LB10PF but differs in package type. The series is designed for applications demanding reliable data buffering without complex control logic overhead.

Replacement Considerations

Cross-reference with IDT72205LB10J8 for functional equivalence. Verify pinout compatibility before substitution. Confirm electrical specifications match system requirements.
