7205L25J8

Overview

The Renesas Electronics Corporation 7205L25J8 is an asynchronous FIFO memory device with a storage capacity of 72K bits, organized as 8K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 25 ns, corresponding to a data rate of 28.5 MHz. The component utilizes a unidirectional bus architecture and is housed in a 32-PLCC package. It supports retransmit capabilities for pointer reset functions.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Retransmit capability allowing read pointer reset to initial position
• Status flags including Empty, Half-Full, and Full indicators

Applications

• Multiprocessing systems requiring data buffering
• Rate matching applications between disparate clock domains
• Data acquisition systems needing overflow prevention

Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Confirm RoHS compliance status and moisture sensitivity levels prior to integration, as legacy parts may have specific handling requirements different from current standards.

Selection Notes

Select this part only if the design requires a 9-bit data width and 8K depth asynchronous FIFO. Verify that the system operates at 5V logic levels, as this device does not support lower voltage supplies. Ensure the application can accommodate the 32-PLCC surface mount package dimensions and pinout compatibility with existing PCB layouts.

Part Context

The 7205L25J8 belongs to the Renesas 7200 series of high-speed CMOS FIFOs. This family is designed for multiprocessing and rate buffer applications. The device provides full expandability by word depth and bit width. It is functionally compatible with earlier generations of similar FIFO architectures while offering improved speed performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available due to the discontinuation status. Designers must evaluate functional equivalents from other manufacturers that match the 8K x 9 organization, 25ns access time, and 32-PLCC package constraints.
