72205LB25TFI8

Overview

The Renesas 72205LB25TFI8 is a synchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 256 words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 40 MHz with an access time of 15 ns. The component features unidirectional bus direction and is housed in a 64-TQFP (10x10) surface-mount package. Maximum supply current is 60 mA, and it functions across a temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with independent read and write clocks for simultaneous data handling
• Programmable status flags including Empty, Full, and Half-Full indicators
• Expandable architecture allowing depth and width expansion

Applications

• Data buffering in multiprocessing systems
• Rate matching between asynchronous data streams
• Network interface buffering
• Video signal processing applications

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures during assembly. Validate pin compatibility with existing PCB footprints before integration into new designs.

Selection Notes

Select this component when synchronous FIFO functionality with 18-bit word width is required. Ensure system voltage aligns with the 4.5 V to 5.5 V operating range. Consider the 64-TQFP package constraints for board layout. Verify that the 40 MHz maximum frequency meets application timing requirements.

Part Context

Part of the Renesas 7200 series synchronous FIFO family. Functionally compatible with other 722x5LB variants. Designed for high-speed data buffering applications requiring reliable first-in-first-out memory management. Manufactured by Renesas Electronics Corporation.

Replacement Considerations

IDT72205LB25TFI8-ND serves as an alternative designation. Verify pinout and electrical specifications match before substitution. Check availability status as original parts are discontinued.
