72265LA10PF8

Overview

The Renesas 72265LA10PF8 is a SuperSync synchronous FIFO with a capacity of 288K bits, organized as 16K words by 18 bits. It operates at data rates up to 100MHz with access times of 6.5ns or 8ns depending on the specific variant documentation. The device supports a supply voltage range of 3V to 3.6V and is housed in a 64-TQFP package.

Feature Summary

• Supports unidirectional data transfer with clocked read and write controls for precise synchronization.
• Features programmable flags to indicate full and empty buffer states.
• Includes relay capability to maintain data integrity during power transitions.

Applications

• High-speed data buffering between asynchronous logic domains
• Interface bridging in telecommunications equipment
• Data acquisition systems requiring precise timing control

Procurement Notes

Verify the exact access time specification (6.5ns vs 8ns) against the official datasheet, as sources vary. Confirm the package type matches your PCB footprint requirements. Check current product status as some listings indicate obsolete status. Ensure voltage compatibility with your system's 3V to 3.6V operating range before integration.

Selection Notes

Select this component when a high-density, fast-access synchronous FIFO is required for unidirectional data flow. The 18-bit width suits applications needing wider data paths than standard 8/16-bit options. Consider the TQFP-64 package constraints and moisture sensitivity level during assembly planning. Verify if the specific speed grade meets your system's timing budget.

Part Context

Part of the Renesas SuperSync family, designed for high-performance memory buffering. The 72265 series offers advanced synchronization features compared to standard FIFOs. This specific model provides a balance of density and speed for complex digital signal processing tasks.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify that alternative parts support the same 18-bit width and 100MHz operation. Ensure voltage levels and package dimensions match exactly.

FAQ

Is the 72265LA10PF8 bidirectional?
