72V263L7-5PF8

FIFOs Memory Overview

The 72V263L7-5PF8 is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 144 kbit, organized as 16K x 9 or 8K x 18. The component supports a maximum clock frequency of 133.3 MHz with an access time of 5 ns. It operates on a single power supply voltage ranging from 3.15 V to 3.45 V. The device is housed in a TQFP-80 package and is designed for unidirectional data transfer applications requiring high-speed buffering.

FIFOs Memory Feature Summary

• Supports flexible bus matching through user-selectable x9 or x18 data bus widths on both read and write ports.
• Eliminates variable latency periods found in previous generations, ensuring consistent data throughput timing.
• Includes programmable flags and partial reset capabilities to retain configuration settings during data clearing.

FIFOs Memory Applications

• Network equipment data buffering
• Video signal processing systems
• Telecommunications infrastructure
• Data communications interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix 'L7' against current manufacturer documentation to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for active product change notices that may affect long-term availability or material composition.

FIFOs Memory Selection Notes

Select this component when designing systems requiring 133.3 MHz synchronous operation with 5 ns access speed. Ensure the application utilizes a 3.3V logic interface compatible with the specified voltage range. Consider the TQFP-80 package constraints for PCB layout and thermal management requirements.

FIFOs Memory Part Context

This part belongs to the 72V263 SuperSync II family, which provides high-performance FIFO solutions for unequal bus size matching. It is functionally related to other devices in the 72V2x3 series but offers specific density and speed configurations tailored for telecommunications and networking buffer applications.

FIFOs Memory Replacement Considerations

Consult official datasheets for direct pin-to-pin replacements within the 72V263 series. Verify compatibility with higher density variants such as the 72V283 if increased storage depth is required, ensuring clock and voltage specifications remain within acceptable limits.
