IDT7201LA35SO8

FIFOs Memory Overview

The IDT7201LA35SO8 is an asynchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5K bits, organized as 512 words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 22.2 MHz and an access time of 35 ns. It operates on a single power supply voltage ranging from 4.5 V to 5.5 V. The component is housed in a 28-SOIC surface-mount package with a width of 8.77 mm. It functions within a commercial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Asynchronous FIFO architecture supporting independent read and write clock domains for buffering data between different speed circuits.
• Unidirectional bus configuration designed for simple point-to-point data flow applications.
• Relay capability allows the device to function as a standard static RAM when required.

FIFOs Memory Applications

• Data buffering in high-speed serial communication interfaces
• Clock domain crossing synchronization in digital logic systems
• Temporary storage in embedded controller data acquisition paths

FIFOs Memory Procurement Notes

Verify the specific suffix 'SO8' against official Renesas documentation, as standard listings typically reference 'SO'. Confirm RoHS compliance status, as many variants in this series are non-compliant. Check for End-of-Life (EOL) notices, as this product family has been subject to discontinuation announcements. Ensure the supplier provides valid traceability for obsolete components.

FIFOs Memory Selection Notes

Select this component when a small, unidirectional buffer is needed for 9-bit wide data paths. The 35 ns access time suits moderate-speed applications up to 22.2 MHz. Consider the 28-SOIC package constraints for PCB layout. Evaluate if bidirectional requirements or wider data buses necessitate alternative models like the 7202 or 7203 series.

FIFOs Memory Part Context

This part belongs to the IDT 7200L/7201LA series of asynchronous FIFOs. It shares architectural similarities with other members like the IDT7201LA35SO but differs in packaging and specific suffix designations. The series is characterized by CMOS technology and TTL-compatible I/O levels, widely used in legacy industrial and networking equipment designs requiring reliable data暂存.
