72251L15JG

Overview

The Renesas Electronics Corporation 72251L15JG is a synchronous FIFO memory device featuring an 8K x 9 organization and 72 kbit storage capacity. It operates with a maximum clock frequency of 66.7 MHz and provides a 10 ns access time. The component supports unidirectional data transfer within a single circuit configuration. It functions reliably within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum supply current of 50 mA. The device is housed in a 32-PLCC package and is designed for surface mount installation.

Feature Summary

• Synchronous operation with programmable full/empty flags
• Unidirectional data bus architecture
• High-speed 66.7 MHz clock capability

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic blocks
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix JG against official datasheets to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and moisture sensitivity level requirements prior to PCB assembly. Check for end-of-life notices or production change notifications that may affect long-term availability and manufacturing consistency.

Selection Notes

Select this component when a synchronous FIFO with 8K depth and 9-bit width is required. Ensure the system design accommodates the 4.5 V to 5.5 V operating voltage range. Verify that the 32-PLCC package fits the available board space and soldering capabilities. Consider the 10 ns access time for timing closure in the target application.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories, which are widely used for data buffering and protocol conversion. The 72251 variant specifically offers synchronous control with a 9-bit data path, distinguishing it from parallel or wider data variants in the same family.

Replacement Considerations

Check for IDT72251L15JGI as a potential cross-reference. Verify electrical parameters and pin compatibility before substitution.
