72V263L6PFG8

FIFOs Memory Overview

The 72V263L6PFG8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation, belonging to the 72V series. It features a storage capacity of 144 kbit, organized as 16K x 9 or 8K x 18 bits. The component supports unidirectional bus direction and operates with a maximum data rate of 100 MHz. Access time is specified at 6.5 ns. It functions within a supply voltage range of 3.15 V to 3.45 V, with a maximum supply current of 35 mA. The device is housed in an 80-LQFP package (80-TQFP 14x14) and is designed for surface mount installation. Operating temperature ranges from 0°C to +70°C.

FIFOs Memory Feature Summary

• Flexible bus matching capabilities on both read and write ports, supporting variable x9/x18 configurations.
• Elimination of variable clock cycle counting delay associated with latency periods found in previous SuperSync devices.
• Supports programmable flags and First Word Fall Through (FWFT) functionality.

FIFOs Memory Applications

• Network buffering applications requiring large data amounts.
• Video processing systems needing bus size matching.
• Telecommunications equipment utilizing unequal bus sizes.
• Data communications interfaces requiring high-speed synchronization.

FIFOs Memory Procurement Notes

Verify component status carefully as this specific part number may be discontinued or subject to end-of-life notices. Confirm availability through authorized distributors only. Check for valid RoHS compliance documentation and moisture sensitivity level ratings before integration into production schedules. Ensure packaging specifications match design requirements.

FIFOs Memory Selection Notes

Select this component when flexible bus width matching between x9 and x18 architectures is required without latency variability. Consider the 100 MHz operational speed and 6.5 ns access time for system timing constraints. Verify that the 80-pin TQFP package fits the PCB layout and that the commercial temperature range meets environmental conditions.

FIFOs Memory Part Context

This device is part of the 72V263 SuperSync II FIFO family, which offers functional compatibility with earlier 72V255/65/75/85 models. It serves as a pin-to-pin compatible alternative to higher density variants like the 72V2x3 series. The SuperSync II architecture improves upon previous generations by removing variable latency delays, making it suitable for precise timing applications in industrial and communication sectors.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible alternatives within the 72V263 series or functionally equivalent SuperSync II devices. Verify if upgraded density parts like the 72V273 are suitable replacements if performance margins allow. Consult manufacturer obsolescence notices for recommended new part numbers.
