72V263L7-5PFI8

FIFOs Memory Overview

The 72V263L7-5PFI8 is a SuperSync II synchronous FIFO manufactured by Renesas Electronics. It features a storage capacity of 144 kbit, organized as 8K x 18 or 16K x 9. The device supports unidirectional data transfer with a maximum clock frequency of 133.3 MHz and an access time of 5 ns. Operating voltage ranges from 3.15 V to 3.45 V, with maximum supply currents of 30 mA or 35 mA depending on configuration. It is housed in an 80-pin TQFP package and operates within an industrial temperature range of -40°C to +85°C.

FIFOs Memory Feature Summary

• Eliminates variable clock cycle counting delay associated with latency periods found in previous SuperSync devices
• Provides flexible bus-matching capabilities for both read and write ports with user-selectable x9/x18 sizing
• Supports independent read and write clocks for asynchronous port operation

FIFOs Memory Applications

• Network buffering applications requiring large data storage
• Video processing systems needing unequal bus size matching
• Telecommunications infrastructure data synchronization
• Data communications interfaces requiring high-speed buffering

FIFOs Memory Procurement Notes

Verify component authenticity through authorized Renesas distributors or official channels. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) handling requirements prior to assembly. Check for product change notices or end-of-life announcements that may affect long-term availability. Ensure packaging specifications match design requirements for surface-mount installation.

FIFOs Memory Selection Notes

Select this component when variable latency is unacceptable and precise timing alignment between disparate bus widths is required. The SuperSync II architecture offers improved performance over earlier generations by removing latency-related delays. Consider the 80-pin TQFP package for space-constrained designs requiring industrial temperature operation. Verify power consumption limits against system thermal constraints given the specified current ratings.

FIFOs Memory Part Context

The 72V263L7-5PFI8 belongs to the 72V2x3 series of SuperSync II FIFOs. It is functionally compatible with higher density variants like the 72V21x3 devices. The series is designed for applications demanding high-speed data buffering and bus matching. Pin-to-pin compatibility facilitates design upgrades within the same family while maintaining board layout integrity.

FIFOs Memory Replacement Considerations

Functionally compatible replacements include other members of the 72V2x3 series such as the 72V253, 72V263, 72V273, and 72V283 variants. These devices share similar SuperSync II characteristics but differ in memory depth and width configurations. Verify pinout compatibility and electrical specifications before substitution.
