72205LB10PFI8

Overview

The Renesas 72205LB10PFI8 is a synchronous FIFO memory component belonging to the 72205LB10 series. It features an organization of 256 words by 18 bits, providing a total capacity of 4.5Kb. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 100 MHz with a typical access time of 6.5 ns. It utilizes a 64-pin TQFP package (14x14 mm) and is designed for unidirectional data buffering applications requiring high-speed performance.

Feature Summary

• Synchronous first-in, first-out memory architecture supporting simultaneous read and write operations under independent clock controls
• High-speed data processing capability with 100 MHz operation frequency and 6.5 ns access time
• Integrated status flags including Full, Empty, Half-Full, and programmable Almost-Empty/Almost-Full indicators
• Output enable control allowing the data bus to enter a high-impedance state

Applications

• Data buffering in optical disk controllers
• Local Area Network (LAN) interface buffering
• Interprocessor communication systems
• Multiprocessing rate buffer applications

Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure packaging specifications match design constraints for surface-mount assembly processes.

Selection Notes

Select this component for designs requiring 18-bit wide synchronous FIFO buffers with high throughput. Compare against the 72V245 series if 3.3V logic compatibility is required instead of 5V TTL levels. Verify pinout compatibility with existing 64-pin TQFP footprints when replacing legacy IDT variants.

Part Context

This component is part of the Renesas 72205LB10 family of synchronous FIFOs, which are successors to earlier IDT products. The series provides expandable depth and width options for various memory density needs. It shares functional similarities with the 72V245 but differs in core voltage requirements and specific timing characteristics.

Replacement Considerations

The IDT72205LB10PF is listed as an alias for this component. Verify pin compatibility and electrical parameters before substituting with other 64-pin TQFP FIFOs from different manufacturers.
