72265LA10PF

Overview

The Renesas Electronics Corporation 72265LA10PF is a SuperSync FIFO memory device with a storage organization of 16K x 18 bits. It operates on a 5V supply voltage and supports a data rate of 100MHz with a 6.5ns access time. The component utilizes a synchronous interface within a 64-pin TQFP package, designed for unidirectional data buffering in high-speed digital systems.

Feature Summary

• SuperSync architecture enabling simultaneous independent read and write clock operations
• Functionally compatible with the 5 Volt 722x5 family while maintaining pin compatibility
• Programmable status flags including Empty, Full, Half-Full, and Almost-Empty/Almost-Full indicators
• Auto power down capability to minimize standby power consumption during idle periods

Applications

• Networking equipment requiring large data buffer management
• Video processing systems handling continuous data streams
• Telecommunications infrastructure utilizing high-speed serial interfaces
• Data communications hardware needing low latency first word data transfer

Procurement Notes

Verify the specific suffix 'PF' against current manufacturer documentation to confirm package type and lead-free status. Confirm availability as this series may be subject to discontinuation notices or production lifecycle changes. Ensure design-in compliance with RoHS directives if required by the target application environment.

Selection Notes

Select this component when a 5V logic interface is required alongside SuperSync performance characteristics. It serves as a direct functional replacement for older 72265 variants where pin compatibility is critical. Consider the 72V265LA10PFG if a 3.3V supply operation is necessary instead of the standard 5V requirement.

Part Context

This part belongs to the IDT 72265 family of SuperSync FIFOs, originally developed by Integrated Device Technology before its acquisition by Renesas. The 72265LA10PF represents the 5V version of the architecture, distinct from the lower-power 3.3V 72V265 series. It is widely recognized for its fixed low first-word data latency and retransmit capabilities.

Replacement Considerations

The 72V265LA10PFG is a functionally compatible alternative operating at 3.3V. Verify voltage level translation requirements when substituting between the 5V 72265 and 3.3V 72V265 families. Check datasheets for any differences in control signal timing or flag behavior.
