72245LB10PFGI

Overview

The Renesas Electronics Corporation 72245LB10PFGI is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 72K bits, organized as 4K words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates on a single 5V supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 60mA. The device is housed in a 68-pin PLCC package and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Supports independent read and write clock operations for flexible dual-clock or single-clock synchronization.
• Includes programmable flags for status monitoring, including empty, full, and almost-empty/almost-full conditions.
• Features output enable control that places the output data bus into a high-impedance state.

Applications

• Data buffering in optical disk controllers
• Local Area Network (LAN) interface applications
• Interprocessor communication systems

Procurement Notes

Verify the specific suffix 'PFGI' against official manufacturer documentation to confirm lead-free status and industrial temperature grade specifications. Confirm RoHS compliance details directly with the supplier. Ensure moisture sensitivity level handling procedures are followed during assembly. Check for end-of-life status or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a 4K x 18 synchronous FIFO with 100MHz performance is required. It is suitable for designs needing 5V logic compatibility and independent clock domains. Consider the 68-PLCC package constraints for PCB layout. Verify if industrial temperature range variants are necessary for the target environment.

Part Context

This part belongs to the Renesas 72245LB10 family of synchronous FIFOs. It serves as a 5V version of the 3.3V 72V245 series. The device provides reliable data buffering for high-speed digital interfaces. It is functionally compatible with similar industry-standard FIFO architectures.

Replacement Considerations

The IDT72245LB10JG is listed as an alias for this component family. Verify pinout and electrical parameter equivalence before substitution. Consult official cross-reference guides for confirmed replacements.
