72205LB25TFI

Overview

The Renesas Electronics Corporation 72205LB25TFI is a synchronous FIFO memory device housed in a 64-TQFP package. It features a storage capacity of 4.5K bits, organized as 256 words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 40MHz and an access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is rated for industrial temperatures from -40°C to +85°C.

Feature Summary

• Synchronous operation with clocked read and write controls for reliable data buffering
• Unidirectional bus architecture supporting 18-bit data width
• Programmable status flags for monitoring full and empty conditions

Applications

• Data buffering in high-speed serial communication interfaces
• Interprocessor communication between microcontrollers and peripherals
• Network interface data handling and protocol conversion

Procurement Notes

Verify the exact suffix 'TFI' against official Renesas documentation to confirm package dimensions and marking details. Confirm RoHS compliance status as sources indicate non-compliance. Check for active obsolescence notices or end-of-life notifications prior to procurement planning.

Selection Notes

Select this component when a 256x18 synchronous FIFO with 15ns access time is required. Ensure the system design accommodates the 4.5V to 5.5V operating voltage range. Verify that the 64-TQFP footprint matches the PCB layout constraints and thermal requirements for the target application environment.

Part Context

This part belongs to the IDT 72205 series of synchronous FIFOs, now manufactured under the Renesas Electronics brand following corporate acquisitions. The 72205LB25 variant specifically denotes the 25ns (40MHz) speed grade within the low-power CMOS family. It serves as a specialized memory buffer for digital signal processing and data acquisition systems.
