7205L50TP

Overview

The Renesas Electronics Corporation 7205L50TP is an asynchronous FIFO memory integrated circuit belonging to the 7200 series. It provides a storage capacity of 72K bits, organized as 8K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 15MHz and features a typical access time of 50ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 120mA. The component is housed in a 28-pin PDIP package designed for through-hole mounting and functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous dual-clock operation enables independent read and write clock domains for flexible interface bridging.
• Unidirectional bus architecture simplifies system design for single-direction data flow applications.
• Through-hole 28-pin PDIP packaging facilitates integration into legacy or high-reliability board layouts.

Applications

• Buffering data streams between components operating at different clock speeds
• Interface bridging in digital signal processing systems
• Data acquisition systems requiring temporary storage before processing

Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt. Ensure supply chain sources are authorized distributors to avoid counterfeit risks. Check for specific lot codes if traceability is required for critical applications.

Selection Notes

Select this component when asynchronous buffering with 8x9 word depth is required. Consider the 50ns access speed and 15MHz limit against system timing constraints. Evaluate the PDIP package suitability for the target PCB technology. Compare against synchronous alternatives if simultaneous clock domains are available.

Part Context

The 7205L50TP is part of the Renesas 7200 series of asynchronous FIFOs. This series offers various capacities and speeds for memory buffering needs. The 7205 variant specifically targets applications needing moderate depth with standard CMOS logic levels. It complements other parts like the 7206 series which offer larger depths.

Replacement Considerations

Public confirmed substitute part numbers: IDT7205L50P. Verify pinout compatibility and electrical specifications before substitution. Note that suffix variations may indicate package or temperature differences.
