72265LA20TFI8

Overview

The Renesas 72265LA20TFI8 is a synchronous FIFO memory device with a storage capacity of 288K bits, organized as 16K words by 18 bits. It operates on a single 3.3V supply and supports data rates up to 50MHz with an access time of 12ns. The component utilizes a 64-pin TQFP package (10x10mm) and features unidirectional bus architecture. It includes programmable flags for status monitoring and supports expansion in depth and width.

Feature Summary

• Functionally compatible with the 5V 722x5 family while operating at 3.3V
• Supports retransmit operation with fixed low first word data latency
• Features independent read and write clocks allowing simultaneous operations
• Includes auto power down capability to minimize standby power consumption

Applications

• Networking equipment buffering
• Video signal processing systems
• Telecommunications data handling
• General data communications interfaces

Procurement Notes

Verify RoHS compliance status carefully as sources indicate conflicting information regarding lead-free specifications. Confirm current product lifecycle status as obsolete or end-of-life documentation may apply. Ensure replacement components match the specific 12ns access time requirement rather than faster variants. Validate package dimensions against existing PCB footprints before procurement.

Selection Notes

Select this component when functional compatibility with legacy 5V designs is required alongside lower power consumption. The 18-bit width suits applications requiring non-standard data bus widths without additional logic. Consider the 12ns speed grade if system timing allows slower performance than the 10ns variant. Verify temperature range requirements against industrial specifications.

Part Context

This part belongs to the 72V265 SuperSync FIFO series, designed for high-performance buffering. It serves as a 3.3V version of the older 72265 family, maintaining pin compatibility. The series targets applications needing large data buffers with predictable latency characteristics in networking and telecom environments.
