72V291L15TFI8

FIFOs Memory Overview

The Renesas Electronics Corporation 72V291L15TFI8 is a synchronous FIFO memory device with a storage capacity of 1.125M bits, organized as 128K words by 9 bits. It operates on a single 3 V to 3.6 V power supply and supports data rates up to 66.7MHz with a 10ns access time. The component features unidirectional bus direction and is housed in a 64-TQFP package measuring 10x10 mm. It includes programmable flags for status indication and supports first-word fall-through functionality.

FIFOs Memory Feature Summary

• Supports independent read and write clocks allowing simultaneous operations
• Features fixed low first word data latency time for retransmit operations
• Includes programmable Almost-Empty and Almost-Full flags for status signaling
• Designed for auto power down to minimize standby power consumption

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify the exact suffix configuration against official documentation, as variations exist within the 72V291 family. Confirm RoHS compliance status and lead-free requirements prior to integration. Check for product discontinuance notices or end-of-life announcements from the manufacturer. Ensure the specific package variant matches the intended PCB footprint design constraints.

FIFOs Memory Selection Notes

Select this component when a high-density 128K x 9 synchronous buffer is required for 3.3V logic systems. It serves as a functional replacement for older 5V 72291 devices while offering lower power consumption. Consider its fixed latency characteristics for applications requiring predictable data transfer timing without variable clock cycle counting delays.

FIFOs Memory Part Context

This part belongs to the Renesas 72V SuperSync FIFO series, designed for high-speed data buffering. It maintains pin compatibility with the 72V2x1 and IDT72V21x1 families. The device eliminates the Frequency Select pin found in previous generations, simplifying clock input management between RCLK and WCLK sources.

FIFOs Memory Replacement Considerations

The 72V291L15TF is a functionally compatible alternative within the same package type. Verify if the specific I8 suffix variant offers distinct packaging or handling characteristics compared to standard TF versions.
