72271LA10PFG8

Overview

The 72271LA10PFG8 is a 32K x 9 SuperSync FIFO memory manufactured by Renesas Electronics Corporation. It features an 8ns access time and operates within a voltage range of 4.5V to 5.5V. The device utilizes a 64-pin TQFP package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

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

Applications

• High-speed data buffering in communication systems
• Data acquisition applications requiring precise timing control
• Industrial network solutions with strict latency requirements

Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm the exact package type and temperature grade. Ensure compatibility with existing system voltage levels and clock configurations before procurement. Check for any recent product change notices or end-of-life announcements that may affect long-term supply availability.

Selection Notes

Select this component when independent read/write clocking is required for asynchronous data transfer between different clock domains. The fixed latency characteristic simplifies timing analysis compared to variable latency FIFOs. Consider the 64-pin TQFP footprint for PCB layout constraints and verify thermal dissipation capabilities for the intended operating environment.

Part Context

This part belongs to the SuperSync FIFO family, designed for high-performance data buffering. It replaces earlier versions by eliminating the frequency select pin, thereby simplifying configuration while maintaining robust retransmit operations and status flagging capabilities for reliable system integration.

Replacement Considerations

Check for direct pin-compatible alternatives within the 722x1 series if available. Verify electrical specifications and package dimensions match exactly before substitution.
