7202LA12SOG

Overview

The Renesas Electronics Corporation 7202LA12SOG is an asynchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 9K bits, organized as 1K words by 9 bits. The component supports a maximum data rate of 50MHz with a typical access time of 12ns. It operates on a single supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 80mA. The device features unidirectional bus directionality and includes retransmit capability. It is housed in a 28-SOIC surface-mount package and is rated for operation within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous dual-clock architecture enables independent read and write operations without requiring a common clock signal.
• Retransmit capability allows data to be held at the output until explicitly acknowledged by the reading system.
• CMOS technology ensures low power consumption while maintaining high-speed data throughput capabilities.

Applications

• Buffering data streams between components operating at different clock frequencies
• Level shifting between logic families with varying voltage requirements
• Temporary data storage in high-speed digital communication interfaces

Procurement Notes

Verify the exact suffix against official Renesas documentation, as 'SOG' may denote specific tape-and-reel packaging or regional variants. Confirm RoHS3 compliance status for environmental regulations. Check for recent Product Change Notices regarding assembly site transfers or marking changes that do not affect electrical function but may impact traceability.

Selection Notes

Select this part when a 1Kx9 depth is required for asynchronous buffering applications. Ensure the 50MHz speed requirement aligns with system timing constraints. Verify that the 28-SOIC footprint fits the PCB layout. Consider the 7202LA12JG variant if a PLCC-32 package is preferred for the same electrical specifications.

Part Context

This component is part of the IDT/Renesas 7200 series of high-performance asynchronous FIFOs. The series offers various depths and speeds, with the 7202 variant specifically providing 1K x 9 word depth. These devices are designed for flexible integration into complex digital systems requiring reliable data synchronization and temporary storage between asynchronous domains.

Replacement Considerations

IDT7202LA12SOG8 is a verified equivalent part number representing the same functional specification. Other 7202LA12 variants exist in different packages such as PLCC-32 (e.g., 7202LA12JG) or PDIP-28 (e.g., 7202LA12TP), which share identical electrical characteristics but require compatible footprints.
