72245LB25TFI

Overview

The Renesas 72245LB25TFI is a synchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 256 words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 40 MHz with an access time of 15 ns. The component utilizes a 64-pin TQFP package (10x10 mm) and functions in unidirectional mode. It is rated for industrial temperatures from -40°C to +85°C and draws a maximum supply current of 60 mA.

Feature Summary

• Synchronous single-clock operation capability
• Programmable status flags support
• Surface-mount packaging for automated assembly

Applications

• Data buffering in network interfaces
• Interprocessor communication systems
• Graphics data handling

Procurement Notes

Verify the specific suffix 'TFI' against official Renesas documentation to confirm the 64-TQFP package configuration. Confirm RoHS compliance status as historical records indicate non-compliance for this series. Validate that the part number matches the exact density and speed grade required for your design, as variations exist within the 72245 family.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO with moderate depth is required. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 64-TQFP footprint constraints during PCB layout. Verify if programmable flags are necessary for flow control, as this feature is supported.

Part Context

This device belongs to the IDT 72205/72245 LB series of synchronous FIFOs manufactured by Renesas Electronics. These components are designed for high-speed data buffering applications requiring reliable synchronization between different clock domains or processing speeds.
