72205LB10PF8

Overview

The Renesas Electronics Corporation 72205LB10PF8 is a synchronous First-In, First-Out (FIFO) memory device designed for high-speed data buffering applications. It features a storage capacity of 4.5K bits, organized as 256 words by 18 bits. The component supports a maximum data rate of 100MHz with an access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-lead Thin Quad Flat Package (TQFP) with dimensions of 14x14mm. It includes programmable flags and supports depth and width expansion capabilities.

Feature Summary

• Synchronous operation with clocked read and write controls for reliable data buffering
• Programmable status flags indicating full, empty, and half-full conditions
• Supports bidirectional bus direction control and depth/width expansion
• Surface-mount installation in a compact 64-TQFP package

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between components operating at different clock speeds
• Temporary storage in telecommunications equipment
• Memory buffering in industrial automation controllers

Procurement Notes

Verify the specific suffix 'PF8' against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical records indicate variations within the 72205 series. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure the supplier provides traceability for the original manufacturer IDT/Renesas lineage.

Selection Notes

Select this component when a small, fast synchronous FIFO is required for 18-bit wide data paths. Compare against the 72205LB10PF if tray packaging is preferred over cut tape. Consider the 72235LB15PFGI8 if larger 2K x 18 capacity is needed. Verify that the 100MHz speed meets system timing requirements. Ensure the 64-TQFP footprint matches the PCB design constraints.

Part Context

This part belongs to the Renesas 7200 series of high-performance synchronous FIFOs. It is functionally similar to the IDT72205LB10PF but distinguished by its reel/cut-tape packaging configuration. The series is known for low power consumption and high-speed performance, widely used in legacy and specialized embedded designs requiring precise data synchronization.

Replacement Considerations

Official substitutes include the 72205LB10PF for tray-packaged equivalents. Cross-reference with IDT72205LB10PF8 for identical functional specifications under the former Integrated Device Technology branding. Verify pin compatibility before substitution.
