72271L10PF

Overview

The Renesas 72271L10PF is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 288K organized as 32K words by 9 bits. The component supports a data rate of 66.7MHz with an access time of 10ns. It operates on a single voltage supply ranging from 4.5V to 5.5V and draws a maximum supply current of 75mA. The device is housed in a 64-TQFP package measuring 14x14mm and functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Supports retransmit operation with fixed, low first word data latency time
• Features independent read and write clocks permitting simultaneous reading and writing
• Includes programmable almost-empty and almost-full flags for status signaling

Applications

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

Procurement Notes

Verify RoHS compliance status as the component may not meet current environmental standards. Confirm availability through authorized channels given potential discontinuation or limited stock. Ensure proper handling procedures are followed due to moisture sensitivity level 3 classification. Validate pin compatibility with existing designs if replacing older supersync FIFO variants.

Selection Notes

Select this part for applications requiring high-speed synchronous data buffering with independent clock domains. Consider the 64-pin TQFP package for surface mount assembly constraints. Evaluate power consumption requirements against the 75mA maximum supply current specification. Verify that the 4.5V to 5.5V operating voltage aligns with system power rails.

Part Context

This component is part of the Renesas 7200 series of SuperSync FIFO memories. It serves as a specialized buffer solution for digital signal processing and communication applications. The device eliminates variable clock cycle counting delays found in previous generations, offering fixed latency characteristics for predictable timing performance in complex data paths.

Replacement Considerations

Check for direct pin-compatible replacements within the 722x1 family. Verify electrical parameter equivalence for voltage and speed specifications when considering alternative suppliers.
