7200L20TP

Overview

The 7200L20TP is an asynchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 16K words by 9 bits. The component supports unidirectional data transfer with a maximum clock frequency of 33.3 MHz and an access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. Designed for commercial use, it functions between 0°C and +70°C. The device is housed in a 28-pin PDIP package suitable for through-hole mounting.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Unidirectional bus architecture simplifies system design for specific data flow requirements.
• High-speed performance supports data rates up to 33.3 MHz with rapid 20 ns access times.
• Robust buffering capability manages data rate mismatches between high-speed and low-speed systems.

Applications

• Buffering data streams between microprocessors and peripheral devices
• Interface bridging in industrial control systems requiring asynchronous communication
• Data acquisition systems managing variable throughput sensors
• Telecommunications equipment handling serial-to-parallel data conversion

Procurement Notes

Verify the exact suffix designation for the target part number, as availability may vary significantly between similar model variants such as the J or P series. Confirm that the 28-PDIP package aligns with existing board footprints and assembly processes. Check for RoHS compliance status if environmental regulations apply to the final product. Ensure the supplier provides valid traceability documentation for this discontinued or legacy component type.

Selection Notes

Select this component when a large buffer depth of 16K words is required for asynchronous data handling. The 9-bit data width accommodates standard byte-oriented systems with parity or error-checking bits. Consider the 20 ns access speed against system timing constraints. Evaluate the 120 mA power consumption against thermal management capabilities in the enclosure. Compare against faster alternatives if higher throughput is necessary.

Part Context

This device belongs to the Renesas 7200L series of asynchronous FIFO memories. The series offers various configurations balancing speed, depth, and interface types. The 7200L20TP specifically targets applications needing substantial buffering capacity with moderate speed requirements. It complements other logic components in complex digital systems where data synchronization is critical.

Replacement Considerations

Direct replacements may be limited due to the specific 16K x 9 organization and 20 ns speed grade. Verify pin compatibility with alternative 28-pin FIFO packages. Cross-reference with newer Renesas generations or compatible third-party asynchronous FIFOs offering identical electrical characteristics and physical dimensions.
