72V263L10PF8

FIFOs Memory Overview

The 72V263L10PF8 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 bits. The device supports bidirectional data transfer with independent read and write clocks operating up to 100 MHz. Access time is specified at 6.5 ns. It operates on a 3.15 V to 3.45 V supply voltage within an industrial temperature range of 0°C to 70°C. The component is housed in an 80-pin TQFP package.

FIFOs Memory Feature Summary

• Supports flexible bus matching through user-selectable x9/x18 data bus widths on both read and write ports.
• Eliminates variable latency periods found in previous generations, providing fixed low first-word data latency.
• Enables simultaneous independent read and write operations using separate clock inputs.

FIFOs Memory Applications

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

FIFOs Memory Procurement Notes

Verify RoHS compliance status carefully, as the specific part number indicates non-compliance with current environmental directives. Confirm package authenticity against the 80-TQFP specification. Check for recent Product Change Notices regarding label changes or assembly site transfers. Ensure the supplier provides valid traceability documentation given the component's obsolete status.

FIFOs Memory Selection Notes

Select this component when interfacing buses of unequal sizes requiring high-speed synchronization. The SuperSync II architecture offers lower power consumption compared to older 5V counterparts. Verify that the required data width matches the available x9 or x18 configurations. Consider the fixed latency characteristics for timing-sensitive applications where variable delays are unacceptable.

FIFOs Memory Part Context

This device belongs to the 72V263 series within the SuperSync II family. It is functionally compatible with earlier 72V255/65/75/85 models but operates at higher speeds. The series is designed for high-density memory buffering. Pin-to-pin compatibility exists with higher density variants like the 72V2x3 and 72V21x3 devices, facilitating design upgrades.

FIFOs Memory Replacement Considerations

No verified public substitute part numbers are available for direct replacement.
