72205LB10PFG

Overview

The 72205LB10PFG is a synchronous FIFO memory device manufactured by Renesas Electronics. It features an organization of 256 words by 18 bits, providing a total storage capacity of 4.5 Kbits. The component operates with a unidirectional bus architecture and supports data rates up to 100 MHz. It requires a supply voltage ranging from 4.5 V to 5.5 V. The device is housed in a 64-lead Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm.

Feature Summary

• Synchronous operation with clocked read and write controls for reliable data buffering
• Unidirectional bus architecture supporting 18-bit data width
• High-speed performance capability reaching 100 MHz data rates

Applications

• Graphics data buffering systems
• Local area network interfaces
• Interprocessor communication links

Procurement Notes

Verify the current lifecycle status before procurement as this part may be discontinued or subject to limited availability. Confirm RoHS compliance requirements against specific project standards, as historical records indicate non-compliance for certain variants. Ensure the 64-TQFP package footprint matches the design layout. Validate that the 4.5 V to 5.5 V operating voltage range aligns with the target system power rails.

Selection Notes

Select this component when a synchronous FIFO with 18-bit width and moderate depth is required. The 100 MHz speed rating suits high-throughput applications like graphics and networking. Ensure the design accommodates the 64-pin TQFP package. Verify that the system voltage supports the specified 4.5 V to 5.5 V range without additional level shifting.

Part Context

This part belongs to the 72205LB10 series of synchronous FIFOs from Renesas. It shares architectural similarities with other members of the family but differs in specific pinout configurations and packaging options. The 72205LB10PFG specifically denotes the 64-lead TQFP variant within this product line.

Replacement Considerations

Public documentation lists IDT72205LB10PF as an alias for this component. Verify functional equivalence and package compatibility before substitution. No other cross-manufacturer replacements are confirmed in available public sources.
