7208L25J8

Overview

The 7208L25J8 is an asynchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 576K bits, organized as 64K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 28.5MHz and an access time of 25ns. It operates within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 120mA. The component is housed in a 32-PLCC package with J-leads, measuring 14mm by 11.46mm. It is designed for surface mount installation and functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Retransmit capability allowing reset of the read pointer to its initial position
• Fully expandable architecture supporting both word depth and bit width modifications

Applications

• Multiprocessing systems requiring data buffering between processors
• Rate matching applications for synchronizing data streams of different speeds
• High-speed digital signal processing interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity handling procedures during storage and assembly. Validate pin compatibility with existing PCB footprints before integration into new designs.

Selection Notes

Select this component when asynchronous FIFO functionality with 9-bit word width is required. Ensure system power supplies remain within the 4.5V to 5.5V operating range. Consider the 32-PLCC package constraints for board layout. Evaluate thermal management needs given the 120mA maximum current consumption at standard operating temperatures.

Part Context

This part belongs to the Renesas 7200 series of high-speed FIFO memories. It shares functional similarities with other members like the 7208L35J8 but differs in access speed specifications. The series is characterized by CMOS technology and TTL-compatible I/O levels. It represents a legacy product line often replaced by newer generations in modern designs.

Replacement Considerations

Public confirmed substitute part numbers include IDT7208L25J8.
