72V51456L6BB

Overview

The Renesas 72V51456L6BB is a multi-queue flow-control integrated circuit housed in a 256-PBGA (17x17) package. It functions as a FIFO with x36 data width and 16 queues, providing 2M memory capacity. The device operates within a supply voltage range of 3.15 V to 3.45 V. It supports surface mount installation and is packaged in trays. The component is classified under specialized ICs for multi-queue flow control applications.

Feature Summary

• Multi-Queue Flow-Control architecture with 16 queues
• FIFO configuration: x36 data width, 2M memory depth
• 256-PBGA (17x17) package with Surface Mount mounting type
• Supply voltage range: 3.15 V to 3.45 V

Applications

Procurement Notes

Verify the RoHS compliance status, as source data indicates 'No'. Confirm the specific packaging quantity per tray, as factory pack quantity is listed as 1 in some records but Tray in others. Ensure the 256-PBGA (17x17) footprint matches the target PCB design. Check for any active product change notices or end-of-life announcements from Renesas.

Selection Notes

Select this component when a fixed 16-queue FIFO structure with x36 bus width is required. The 3.3V nominal supply voltage must be strictly maintained between 3.15 V and 3.45 V. The 256-pin BGA package requires appropriate surface mount assembly capabilities. Verify if the specific queue count and memory depth meet the system buffering requirements compared to other variants in the 72V series.

Part Context

This part belongs to the IDT/Renesas TeraSync multi-queue flow-control family. It shares the 256-BBGA package form factor with related parts like the 72V51453L6BB8. The manufacturer transitioned from Integrated Device Technology (IDT) to Renesas Electronics Corporation. This specific model provides a fixed 16-queue configuration, distinct from configurable queue models in the same series.

Replacement Considerations

The 72V51456L6BB8 is an alternative designation for the same functional device. Cross-reference pinouts and electrical specifications with the official datasheet before substitution.
