72205LB10PFI

Overview

The Renesas Electronics Corporation 72205LB10PFI is a synchronous FIFO memory device belonging to the 72205LB10 series. It features an organization of 256 words by 18 bits, providing a total storage capacity of 4.5K bits. The component operates with a maximum data rate of 100MHz and supports a minimum access time of 6.5ns. It functions within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device utilizes a 64-pin TQFP package (14x14mm) and is rated for operation in commercial temperatures from 0°C to 70°C.

Feature Summary

• Synchronous first-in, first-out memory architecture supporting unidirectional data flow
• High-speed performance capability up to 100MHz with 6.5ns access time
• Programmable status flags including Empty, Full, Half-Full, Almost-Empty, and Almost-Full indicators
• Supports asynchronous or coincident read and write clock operations

Applications

• Optical disk controllers
• Local Area Networks (LAN)
• Interprocessor communication systems

Procurement Notes

Verify the exact suffix PFI against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as sources indicate non-compliance for similar variants. Check moisture sensitivity level requirements for handling. Validate lead-free status if required by assembly processes. Ensure availability aligns with end-of-life notices for the 72205 family.

Selection Notes

Select this component for applications requiring buffered data transfer between asynchronous domains at high speeds. The 18-bit width suits parallel data buses. Verify that the 64-TQFP package fits the PCB layout constraints. Ensure the 4.5V to 5.5V supply range matches the system power rails. Consider the 0°C to 70°C operating temperature range for environmental suitability.

Part Context

This part belongs to the Renesas 72205LB10 series of synchronous FIFOs. It is functionally related to other members like the 72205LB10PF but may differ in specific suffix designations. The series is designed for buffering in multiprocessing and rate-matching scenarios. It shares architectural similarities with the broader 72V2x5 family but operates at different voltage levels.
