72245LB15JGI8

Overview

The Renesas Electronics Corporation 72245LB15JGI8 is a synchronous FIFO memory device organized as 4K x 18 bits, providing a total storage capacity of 72 kilobits. It features a unidirectional data bus architecture with a maximum access time of 10 nanoseconds and operates at clock frequencies up to 66.7 MHz. The component is supplied in a 68-pin PLCC package and requires a supply voltage between 4.5 V and 5.5 V. It supports programmable flags for status monitoring and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Synchronous operation with high-speed data handling capabilities
• Programmable full and empty flag outputs for buffer management
• Unidirectional data flow architecture for dedicated input/output paths

Applications

• High-speed data buffering in telecommunications systems
• Interface bridging between asynchronous logic blocks
• Data acquisition system temporary storage

Procurement Notes

Verify the specific suffix JGI8 against official datasheets to confirm the 68-PLCC package and industrial temperature rating. Confirm RoHS compliance status as manufacturing sites may vary. Check for End-of-Life notices or obsolescence warnings from Renesas before procurement planning.

Selection Notes

Select this component when a unidirectional synchronous FIFO with 18-bit word width is required. Ensure the design accommodates the 68-pin PLCC footprint and 4.5V to 5.5V power supply constraints. Verify that the 10ns access time meets the system timing requirements for the target application frequency.

Part Context

This part belongs to the IDT 722x5LB series of synchronous FIFOs, designed for high-performance data buffering applications. The series offers various organization options and speeds, with the LB variant typically supporting lower voltage operations compared to standard L versions.

Replacement Considerations

Consult official substitution guides for equivalent parts within the IDT 722x5 family. Verify pin compatibility and electrical specifications before replacing.
