72265LA15PF8

Overview

The 72265LA15PF8 is a SuperSync FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 16K words by 9 bits. The component supports unidirectional data transfer with a maximum clock frequency of 66.7MHz and an access time of 10ns. It operates on a single 3V to 3.6V power supply and draws a maximum supply current of 55mA. The device is housed in a 64-pin TQFP package (14x14mm) and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• SuperSync architecture enables independent read and write clocks for simultaneous operations.
• Supports retransmit operation with fixed low first word data latency.
• Includes programmable flags for empty, full, half-full, almost-empty, and almost-full states.
• Features auto power down capability to minimize standby power consumption.

Applications

• Data buffering in networking equipment
• Video signal processing systems
• Telecommunications infrastructure
• Interprocessor communication interfaces

Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as some variants may differ. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 16K x 9 synchronous FIFO with independent clocks is required. Ensure the system voltage aligns with the 3V to 3.6V operating range. Verify that the 64-TQFP package fits the PCB layout constraints and thermal requirements for the intended application environment.

Part Context

This part belongs to the 72V265 family of SuperSync FIFOs. It serves as a 3.3V version functionally compatible with the 5V 72265 series. The design eliminates the Frequency Select pin, simplifying clock management between RCLK and WCLK inputs while maintaining high-speed data throughput capabilities.

Replacement Considerations

The 72265LA15PFG is a documented alternative offering industrial temperature range support (-40°C to +85°C). Verify pin compatibility and electrical specifications before substitution. Consult official datasheets to ensure functional equivalence regarding flag outputs and power-down modes.
