72271LA10TF8

Overview

The 72271LA10TF8 is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 288K bits, organized as 32K words by 9 bits. The component supports data rates up to 100MHz with an access time of 6.5ns. It operates on a single 3V to 3.6V power supply and draws a maximum current of 55mA. The device utilizes a unidirectional bus architecture and is housed in a 64-TQFP package measuring 10x10mm. It functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports retransmit operation with fixed, low first word data latency time
• Features programmable almost-empty and almost-full flags for status signaling
• Allows independent read and write clocks to permit simultaneous operations
• Includes auto power down functionality to minimize standby power consumption

Applications

• Data buffering in graphics systems
• Local area network interfaces
• Interprocessor communication links

Procurement Notes

Verify the specific suffix 'LA' against official datasheets to confirm voltage and speed variants. Confirm RoHS compliance status as documentation indicates non-compliance. Check moisture sensitivity level requirements for handling. Validate package dimensions against design constraints. Ensure availability through authorized channels due to discontinuation status.

Selection Notes

Select this component when a 32K x 9 synchronous FIFO is required for high-speed data buffering. Verify that the 3V to 3.6V operating voltage matches system rails. Ensure the 64-TQFP package fits the PCB layout. Consider the 100MHz data rate capability for interface timing. Confirm temperature range suitability for the intended environment.

Part Context

This part belongs to the 72V series of SuperSync FIFOs from Renesas. It replaces older generations like the 72271L10. The series is characterized by independent read/write clocks and fixed latency. It is designed for applications requiring reliable data buffering between asynchronous domains.

Replacement Considerations

Check for direct pin-compatible replacements within the 72V family. Verify if updated versions with RoHS compliance are available. Consult manufacturer notices for end-of-life alternatives.
