72V2105L15PFI8

FIFOs Memory Overview

The 72V2105L15PFI8 is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 4.5M bits, organized as 256K words by 18 bits. The component supports unidirectional data transfer with a maximum clock frequency of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 3V to 3.6V and has a maximum supply current of 60mA. The device is housed in a 64-TQFP (14x14) surface-mount package and is rated for an operating temperature range of -40°C to 85°C.

FIFOs Memory Feature Summary

• Supports First-Word-Fall-Through (FWFT) mode for immediate data availability upon read assertion.
• Includes programmable full and empty flags to facilitate precise buffer management.
• Provides relay capability to enable cascading of multiple devices for expanded memory depth.

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between asynchronous logic domains
• Data acquisition systems requiring temporary storage

FIFOs Memory Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm tape-and-reel packaging and RoHS compliance status. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity. Confirm that the moisture sensitivity level and reflow soldering profiles align with your assembly process requirements before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when a 256K x 18 word depth is required for synchronous data buffering. Ensure the system design accommodates the 3V to 3.6V supply voltage range and the 60mA maximum current consumption. Verify that the 66.7MHz clock speed meets the application's throughput needs and that the 64-TQFP package fits the board layout constraints.

FIFOs Memory Part Context

This part belongs to the Renesas 72V2105 series of SuperSync FIFOs. It shares architectural similarities with other variants in the family but differs in speed grade and packaging configuration. The 72V2105 series is designed for high-performance applications requiring reliable data synchronization and buffering capabilities across various industrial and communication sectors.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible replacements within the same series, such as the 72V2105L10PFGI, noting differences in access time and operating temperature range. Verify functional equivalence regarding FWFT support and relay capabilities before substitution.
