7202LA25TP

Overview

The Renesas Electronics Corporation 7202LA25TP is an asynchronous first-in, first-out (FIFO) memory device. It features a storage organization of 1K x 9 bits, providing a total capacity of 9 kbits. The component supports unidirectional data transfer with a maximum clock frequency of 25 MHz and a typical access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 28-pin plastic dual in-line package (PDIP).

Feature Summary

• Asynchronous FIFO architecture for buffering data between different clock domains.
• Unidirectional data flow capability for sequential input and output operations.
• CMOS technology ensuring low power consumption and high noise immunity.

Applications

• Data buffering in digital signal processing systems.
• Interface bridging between microprocessors and peripheral devices.
• Temporary storage in communication interface circuits.

Procurement Notes

Verify the specific suffix 'TP' against the official datasheet to confirm the package type and temperature rating. Confirm RoHS compliance status as it may vary by production batch. Check for obsolescence notices from Renesas, as older CMOS FIFOs are frequently discontinued. Ensure the 5V logic level compatibility matches the target system requirements before procurement.

Selection Notes

Select this component when an asynchronous buffer is required for 9-bit wide data paths. Compare access times and pin counts against other FIFO families if higher density or faster speeds are needed. Verify that the PDIP-28 package fits the available PCB real estate. Consider alternative models if surface-mount packaging is preferred over through-hole installation.

Part Context

This part belongs to the IDT 7202 series of asynchronous FIFOs, originally developed by Integrated Device Technology and later acquired by Renesas. These components are standard solutions for managing data flow rates between asynchronous systems. The 7202LA variant specifically denotes the speed grade and package configuration within this legacy product line.

Replacement Considerations

Official substitutes include the IDT7202L25SO for surface mount applications. Cross-reference with Renesas documentation for direct pin-compatible replacements. Verify electrical specifications match exactly before substituting.
