72V205L15PFI

FIFOs Memory Overview

The Renesas Electronics Corporation 72V205L15PFI is a synchronous FIFO memory device belonging to the 72V series. It features a storage capacity of 4.5K bits, organized as 256 words by 18 bits. The component supports a maximum data rate of 66.7MHz with an access time of 10ns. It operates on a single power supply voltage ranging from 3 V to 3.6 V and draws a maximum supply current of 30mA. The device utilizes a 64-LQFP package with surface mount installation. It functions as a unidirectional buffer with programmable flag support and First Word Fall Through (FWFT) capability.

FIFOs Memory Feature Summary

• Synchronous operation with configurable read and write clocks for flexible data buffering
• Programmable status flags including empty, full, almost-empty, and almost-full indicators
• Supports First Word Fall Through timing for reduced latency in data transfer
• Unidirectional bus architecture designed for interprocessor communication

FIFOs Memory Applications

• Optical disk controller data buffering
• Local Area Network (LAN) interface buffering
• Interprocessor communication links

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as specific suffixes may indicate non-compliant variants. Check moisture sensitivity level handling requirements during storage and assembly. Ensure the ordering suffix matches the required temperature grade and package variant. Validate lead-free status against project specifications before procurement.

FIFOs Memory Selection Notes

Select this component when a unidirectional synchronous FIFO with 18-bit width is required. Ensure the system voltage aligns with the 3 V to 3.6 V operating range. Verify that the 64-pin TQFP package fits the PCB layout constraints. Consider the 10ns access time for timing closure in high-speed designs. Confirm if FWFT functionality is necessary for the specific application logic.

FIFOs Memory Part Context

This part belongs to the IDT/Renesas 72V2x5 family of high-performance synchronous FIFOs. The family offers various densities and speeds, typically used in digital signal processing and networking applications. The 72V205 specifically provides a 256x18 configuration, balancing depth and width for moderate buffering needs. It shares architectural similarities with other members like the 72V245 but differs in organization and speed grades.
