72V205L10TF8

FIFOs Memory Overview

The Renesas 72V205L10TF8 is a synchronous FIFO memory device with an organization of 256 x 18 bits and a total storage capacity of 4.608 kbit. It operates on a unidirectional data bus and supports a maximum clock frequency of 100 MHz with a typical access time of 10 ns. The component functions within a supply voltage range of 3 V to 3.6 V, drawing a maximum power supply current of 30 mA. It is housed in a 64-pin TQFP package and is rated for operation between 0°C and +70°C.

FIFOs Memory Feature Summary

• Synchronous operation with independent read and write clocks allowing simultaneous data transfer.
• Fixed low first word data latency time for predictable signal timing.
• Programmable status flags including empty, full, half-full, almost-empty, and almost-full indicators.
• Supports retransmit operations with fixed latency characteristics.

FIFOs Memory Applications

• High-speed data buffering in industrial communication networks.
• Interface bridging between asynchronous logic components operating at different clock rates.
• Data acquisition systems requiring temporary storage before processing.
• Buffering applications in embedded control systems.

FIFOs Memory Procurement Notes

Verify the specific suffix TF8 against official Renesas documentation to confirm the tape-and-reel packaging configuration. Confirm RoHS compliance status as some variants may differ. Check for obsolescence notices or lifecycle changes directly from the manufacturer. Ensure the 64-TQFP footprint matches the target PCB design. Validate moisture sensitivity level requirements for assembly processes.

FIFOs Memory Selection Notes

Select this component when a 256-word by 18-bit depth is required for synchronous buffering. The 100 MHz speed rating suits high-throughput interfaces. Consider the 3.3V supply requirement and ensure compatibility with system voltage levels. The unidirectional nature defines its use case compared to bidirectional alternatives. Verify that the 10 ns access time meets the system timing constraints.

FIFOs Memory Part Context

This part belongs to the Renesas 72V2x5 SuperSync FIFO family, designed for 3.3V operation. It offers functional compatibility with previous generations while eliminating variable clock cycle counting delays. The series provides expandability in both depth and width through parallel connection options. It targets applications needing reliable, low-latency data storage in industrial and commercial environments.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the 72V2x5 series such as the 72V205L15 variant if slower speeds are acceptable. Verify functional equivalence with IDT-branded counterparts like the IDT72V205L10TF8. Ensure any substitute maintains the same 256x18 organization and synchronous timing characteristics.
