72215LB15PFGI8

Overview

The Renesas 72215LB15PFGI8 is a synchronous FIFO memory device with a storage capacity of 9K bits, organized as 512 words by 18 bits. It operates at a maximum clock rate of 66.7MHz with a 10ns access time. The component supports unidirectional data transfer and functions within a supply voltage range of 4.5V to 5.5V. It draws a maximum supply current of 60mA and is housed in a 64-TQFP package measuring 14x14mm. The device is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Synchronous operation with dedicated read and write clocks
• Unidirectional data flow architecture
• Programmable full and empty flag outputs

Applications

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

Procurement Notes

Verify the obsolete status and End-of-Life (EOL) notice before procurement. Confirm availability through authorized distributors or surplus channels. Ensure compatibility with existing system voltage levels and interface requirements. Check for alternative packages if lead times are critical. Validate RoHS compliance documentation for regulatory adherence.

Selection Notes

Select this component for applications requiring moderate depth FIFO buffers with 18-bit word width. Consider the 66.7MHz speed limit for timing constraints. Evaluate the TQFP-64 package for PCB space and thermal management. Compare against wider or deeper alternatives if system requirements exceed 512-word capacity.

Part Context

This part belongs to the IDT 722xx series of synchronous FIFOs. It shares architectural similarities with other members like the 72235LB15PFGI8 but differs in memory depth. The series is designed for general-purpose data buffering in industrial and commercial electronics.

Replacement Considerations

Official substitutes include IDT72235LB15PFGI8 for increased depth. Verify pinout compatibility and electrical specifications when cross-referencing with other 722xx family members.
