7208L25JGI8

Overview

The Renesas Electronics Corporation 7208L25JGI8 is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 576K bits, organized as 64K words by 9 bits. It operates with a maximum data rate of 28.5 MHz and provides a typical access time of 25 ns. The device supports unidirectional bus directionality and functions within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 32-PLCC package and is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation enables independent read and write clock domains for flexible interface bridging.
• Unidirectional data flow simplifies system architecture for specific memory buffering applications.
• Industrial temperature rating ensures reliable performance across wide environmental conditions.

Applications

• Data buffering between high-speed processors and slower peripheral devices
• Interface bridging between systems operating at different clock frequencies
• Temporary data storage in communication protocol conversion circuits

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against project specifications, as this variant may not meet current standards. Validate package integrity upon receipt, ensuring the PLCC-32 leads are undamaged. Check datasheet revisions for any pinout or electrical characteristic updates prior to final design integration.

Selection Notes

Select this component when asynchronous FIFO functionality with 64K x 9 depth is required. Ensure the system power supply remains stable within the 4.5 V to 5.5 V range. Verify that the 25 ns access time meets the timing constraints of the target application. Consider the PLCC-32 package compatibility with existing PCB footprints and assembly processes.
