72265LA20PF8

Overview

The 72265LA20PF8 is a SuperSync FIFO memory device manufactured by Renesas Electronics. It features a storage organization of 16K x 18 bits, providing a total capacity of 288 Kbits. The component operates with a maximum data rate of 50 MHz and an access time of 20 ns. It supports a supply voltage range from 4.5 V to 5.5 V and functions within an industrial temperature range of -40°C to +85°C. The device is housed in a 64-pin TQFP package.

Feature Summary

• SuperSync architecture enables independent read and write clocks for simultaneous operations
• Fixed low first word data latency minimizes delay during retransmit operations
• Programmable Almost-Empty and Almost-Full flags allow flexible status monitoring
• Auto power down feature reduces standby power consumption

Applications

• Networking equipment buffering
• Video signal processing systems
• Telecommunications infrastructure
• High-speed data communications interfaces

Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as legacy parts may have varying environmental declarations. Check for active obsolescence notices or last-time buy notifications before finalizing procurement plans.

Selection Notes

Select this component when a 3.3V-compatible alternative is not required and a 5V logic interface is necessary. Ensure the design accommodates the 64-pin TQFP footprint and meets the thermal requirements for the specified industrial temperature range. Verify that the 16K depth and 18-bit width align with system buffer requirements.

Part Context

This part belongs to the 72265 SuperSync FIFO family, designed for high-performance data buffering. It serves as a functionally compatible version of earlier 5V SRAM-based FIFOs but optimized for synchronous operation. The series is widely used in applications requiring large data buffers with predictable latency characteristics.

Replacement Considerations

The 72V265LA10PFG is a functionally compatible 3.3V alternative within the same product family. Verify voltage level compatibility and clock frequency requirements before substitution.
