72V811L15PFI

FIFOs Memory Overview

The Renesas 72V811L15PFI is a dual synchronous FIFO memory device housed in a 64-LQFP package. It provides a total storage capacity of 9K bits, configured as two independent 512 x 9 bit buffers or a single unified buffer. The component supports data transfer rates up to 66.7MHz with a typical access time of 10ns. It operates within a supply voltage range of 3.0V to 3.6V and draws a maximum supply current of 40mA. The device is designed for surface mount installation and functions reliably across an industrial temperature range of -40°C to +85°C.

FIFOs Memory Feature Summary

• Dual architecture allows operation as two separate 512x9 FIFOs or one combined 1Kx9 FIFO
• Synchronous interface supporting high-speed data buffering at 66.7MHz
• Programmable status flags enable precise control over read and write operations
• Industrial grade reliability with extended temperature range support

FIFOs Memory Applications

• High-speed data buffering between asynchronous system domains
• Interface bridging in telecommunications equipment
• Data acquisition systems requiring temporary storage
• Network switch packet buffering applications

FIFOs Memory Procurement Notes

Verify RoHS compliance status carefully as the component may not meet current environmental regulations. Confirm package integrity upon receipt due to long-term availability issues. Check for specific suffix variations that might indicate pinout or electrical differences. Ensure design-in compatibility with existing 3.3V logic levels. Validate lead times as this part may be subject to discontinuation or limited production runs.

FIFOs Memory Selection Notes

Select this component when dual independent buffering channels are required within a single footprint. The 9-bit word width suits non-standard data bus interfaces. Consider the 66.7MHz speed limit for timing constraints. Evaluate power consumption against system thermal budgets. Compare against single-channel alternatives if only one buffer is needed to optimize board space.

FIFOs Memory Part Context

This device belongs to the 72V series of synchronous FIFOs manufactured by Renesas Electronics. It shares architectural similarities with other members like the 72V2101 and 72V851 but offers distinct dual-buffer capabilities. The series is known for low latency and high-density integration in compact packages. It serves as a legacy solution for high-performance memory interfacing tasks.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference compatibility with newer Renesas generations or third-party equivalents carefully. Ensure functional equivalence regarding pinout and electrical specifications before substitution.
