72245LB10JG8

Overview

The Renesas Electronics Corporation 72245LB10JG8 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 per word. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 60mA. The device is housed in a 68-PLCC package with dimensions of 24.21mm x 24.21mm. It supports programmable flags for status monitoring.

Feature Summary

• Synchronous first-in, first-out memory architecture with clocked read and write controls
• Supports single-clock or dual-clock operation modes
• Includes programmable empty, full, almost-empty, and almost-full flags
• Output enable function places the output data bus in a high-impedance state

Applications

• Optical disk controllers
• Local Area Networks (LANs)
• Interprocessor communication

Procurement Notes

Verify the exact suffix designation against official Renesas documentation, as the JG8 variant may differ from the standard JG version regarding packaging or moisture sensitivity. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors. Check for end-of-life notices or production change notifications that might affect long-term availability. Ensure the selected package type matches the PCB footprint requirements precisely.

Selection Notes

Select this component when a 18-bit wide synchronous FIFO is required for buffering applications. Consider the 100MHz speed and 6.5ns access time for high-speed data processing needs. Evaluate the 68-pin PLCC package constraints against available board space. Compare with the 3.3V 72V245 variant if lower voltage operation is necessary instead of the standard 5V logic levels provided here.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs, which are designed for versatile data buffering tasks. The series includes various densities and speeds, with the 72245 offering a 4Kx18 organization. These devices are commonly used in systems requiring temporary data storage between asynchronous or synchronous domains, such as network interfaces and graphics controllers.

Replacement Considerations

The IDT72245LB10JG8 is listed as an alias for this part number. Verify pinout and electrical compatibility before substitution.
