7202LA50JG

Overview

The Renesas Electronics Corporation 7202LA50JG is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 50 MHz. The component features a 12 ns access time and is housed in a 32-PLCC package measuring 14x11.46 mm. It functions as a unidirectional buffer with relay capability and is rated for operation between 0°C and 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface bridging.
• Unidirectional bus direction simplifies integration into point-to-point data transfer architectures.
• Relay capability enables the preservation of stored data during power-down or system resets.

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary data storage in high-speed digital signal processing chains

Procurement Notes

Verify the specific suffix JG confirms the 32-PLCC package variant. Confirm RoHS compliance status as documentation varies by production batch. Check moisture sensitivity level requirements for surface-mount assembly processes. Ensure the unidirectional configuration meets the target system's data flow needs.

Selection Notes

Select this part when a 50 MHz asynchronous FIFO is required in a PLCC package. Compare against the 7202LA12JG for slower speed options or the IDT7202LA50SO8 for SOIC packaging alternatives. Verify that the 9-bit word width aligns with the application's data bus requirements.

Part Context

This component belongs to the 7202L series of CMOS parallel FIFOs manufactured by Renesas Electronics. The series provides various speed grades and package options for asynchronous memory applications. The 7202LA50JG specifically targets designs requiring moderate speed performance in a standard plastic leaded chip carrier form factor.

Replacement Considerations

IDT7202LA50JG is listed as an alias for this component. The IDT7202LA50SO8 offers identical electrical specifications but utilizes a 28-SOIC package instead of PLCC. Verify pin compatibility before substituting packages.
