72125L25TP

Overview

The Renesas Electronics Corporation 72125L25TP is an asynchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 16K words with a 16-bit data bus width, organized as 1K x 16. The component supports unidirectional data transfer and operates with a maximum clock frequency of 40 MHz. Access time is specified at 50 ns. It functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 100 mA. The device is housed in a 28-SOIC package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Asynchronous operation for flexible interface timing between different clock domains
• Unidirectional data flow architecture for standard buffer applications
• Integrated status flags indicating full and empty conditions

Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between microprocessors and peripheral devices
• Temporary storage in communication protocol converters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance requirements against specific project standards, as legacy parts may not meet current environmental directives. Validate package integrity upon receipt, ensuring no physical damage to the SOIC leads. Cross-reference datasheet revisions to ensure pinout compatibility with existing designs.

Selection Notes

Select this component when asynchronous buffering with 16-bit width is required. Ensure system voltage aligns with the 4.5V to 5.5V specification. Consider the 50ns access time for timing closure. Verify that the 28-SOIC package fits the PCB layout constraints. Check if synchronous alternatives are available if lower latency is needed.

Part Context

The 72125L25TP is part of the Renesas 7200 series of FIFO memories, previously manufactured under IDT branding. This series provides standalone memory solutions for data buffering without processor intervention. The 72125 variant specifically offers 16K x 16 organization. The TP suffix indicates the 28-SOIC plastic package type. This family is designed for general-purpose high-speed data handling.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Engineers should evaluate newer asynchronous FIFO families from Renesas or other manufacturers with compatible pinouts and electrical specifications.
