72811L15PFG

FIFOs Memory Overview

The Renesas 72811L15PFG is a dual synchronous FIFO memory device featuring two independent 4K x 9 bit buffers within a single package. It supports both single-clock and asynchronous dual-clock operations, allowing flexible data buffering configurations. The component operates at a maximum clock frequency of 40MHz with a 15ns access time. It is designed for applications requiring high-speed data handling, such as graphics processing, local area networks, and interprocessor communication, utilizing standard 3.3V logic levels.

FIFOs Memory Feature Summary

• Dual independent FIFO structures providing separate control, data, and flag lines for each buffer
• Supports single-clock operation or asynchronous dual-clock operation modes
• Enables flexible system configurations including priority buffering, bidirectional operation, and width expansion

FIFOs Memory Applications

• Graphics data buffering systems
• Local area network interface controllers
• Interprocessor communication links

FIFOs Memory Procurement Notes

Verify the specific suffix PFG to confirm the TQFP-32 package variant. Confirm RoHS compliance status and lead-free designation against current manufacturer notices. Check for obsolescence announcements or last-time-buy dates prior to ordering. Ensure voltage supply requirements match the 3.3V specification for this model variant.

FIFOs Memory Selection Notes

Select this component when dual independent buffering is required without external multiplexing. Compare against single FIFO models if only one buffer is needed. Verify that the 4K depth and 9-bit width meet system data path requirements. Consider pin count and package size constraints relative to the TQFP-32 footprint.

FIFOs Memory Part Context

This part belongs to the 72801/72811 series of dual synchronous FIFOs from Renesas. It is functionally equivalent to two integrated 72211 devices in one package. The series is designed for high-performance data buffering in digital systems requiring reliable first-in-first-out memory management.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the 728xx series. Verify pin compatibility and electrical specifications before replacing with other dual FIFO parts. Consult official replacement guides for discontinued variants.
