72215LB15TFI

Overview

The Renesas Electronics Corporation 72215LB15TFI is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 9K bits, organized as 512 words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-TQFP (10x10) surface-mount package and functions reliably across an industrial temperature range of -40°C to 85°C.

Feature Summary

• Provides reliable data buffering for high-speed digital systems through synchronous read and write control mechanisms.

Applications

• Data buffering in graphics processing units
• Interprocessor communication interfaces
• Local area network data handling

Procurement Notes

Verify component authenticity due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt. Ensure compatibility with existing system voltage levels before integration into new designs.

Selection Notes

Select this component when a 512 x 18 synchronous FIFO configuration is required. Consider the 15ns access speed and 66.7MHz operational limit for timing constraints. Verify that the 64-TQFP package fits the available PCB footprint. Check if the -40°C to 85°C operating range meets environmental specifications.

Part Context

This part belongs to the IDT 72205/72215/72235/72245 LB family of synchronous FIFOs. These devices are designed for high-performance data buffering applications. The 72215 variant specifically offers 9K bit depth. The LB suffix indicates low-power CMOS technology. This family provides flexible interface options for various system architectures.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 72215 series. Verify equivalent speed grades and voltage ranges. Consider newer generations from Renesas or IDT if availability is critical. Ensure functional equivalence for specific application requirements.
