IDT7201LA25SO8

FIFOs Memory Overview

The IDT7201LA25SO8 is an asynchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The component supports a data rate of 28.5MHz with a maximum access time of 25ns. It operates on a single power supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 80mA. The device utilizes a unidirectional bus architecture and is housed in a 28-SOIC surface-mount package.

FIFOs Memory Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• CMOS technology implementation

FIFOs Memory Applications

• Data buffering between different clock domains
• Interface bridging in digital systems
• Temporary data storage in high-speed logic circuits

FIFOs Memory Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status as legacy variants may differ. Check for end-of-life notices or obsolescence warnings before procurement planning. Ensure the 28-SOIC package dimensions match the target PCB footprint requirements.

FIFOs Memory Selection Notes

Select this component when a small-capacity asynchronous FIFO is required for 5V logic interfaces. The 512x9 organization suits applications needing modest buffer depths. Verify that the 25ns access time meets the system timing constraints. Consider the SOIC package availability if surface-mount assembly is preferred over PLCC or DIP options.

FIFOs Memory Part Context

This part belongs to the IDT 7201L series of asynchronous FIFOs. It shares architectural similarities with other members like the 7201LA25J8 but differs in package type. The series is designed for general-purpose data buffering in CMOS logic environments. Renesas continues to support legacy IDT product lines through official datasheets and technical resources.

FIFOs Memory Replacement Considerations

Direct substitutes include IDT7201LA25J8 (PLCC package) and IDT7201LA25TPG (PDIP package). Verify functional compatibility regarding pinouts and electrical characteristics before substitution.
