7205L15J8

Overview

The Renesas Electronics Corporation 7205L15J8 is an asynchronous FIFO memory integrated circuit designed for high-speed data buffering. It features a storage capacity of 72K bits, organized as 8K words by 9 bits. The device supports a maximum data rate of 40 MHz with a typical access time of 15 ns. It operates on a single 3 V to 3.6 V power supply and draws a maximum supply current of 75 mA. The component is housed in a 32-pin PLCC package with J-leads, suitable for surface mount installation. It functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation allows simultaneous independent read and write cycles without a shared clock constraint.
• Uni-directional bus architecture simplifies interface design for dedicated data flow applications.
• Retransmit capability enables the reset of the read pointer to its initial position upon command.

Applications

• Multiprocessing systems requiring data synchronization between different clock domains
• Rate buffer applications for matching data transfer speeds between components
• High-speed digital signal processing interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure voltage supply stability within the specified 3 V to 3.6 V range to maintain performance integrity. Check for lead-free compliance if required by specific environmental regulations.

Selection Notes

Select this component when a 9-bit wide asynchronous FIFO is required for uni-directional data buffering. Consider the 15 ns access time for timing constraints in 40 MHz systems. Evaluate the 32-PLCC package dimensions against available PCB space. Compare power consumption specifications against system thermal limits.
