7200L20J

Overview

The Renesas Electronics Corporation 7200L20J is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 2.25K bits, organized as 256 words by 9 bits. It operates with a maximum access time of 20 nanoseconds and supports a data rate of 33.3 MHz. The device functions within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 80 mA. It utilizes a unidirectional bus architecture and is housed in a 32-PLCC package with J-leads, measuring 14x11.46 mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Asynchronous operation enabling independent read and write clock domains
• Unidirectional data flow architecture for simple interface integration
• Built-in relay capability for signal buffering applications

Applications

• Data buffering in digital communication systems
• Interface bridging between components with different clock speeds
• Temporary data storage in embedded processing units

Procurement Notes

Verify the obsolete status and discontinuation notice before procurement planning. Confirm that the 32-PLCC package dimensions match the target PCB footprint. Ensure the 4.5V to 5.5V supply voltage requirement aligns with the system power design. Check for RoHS compliance limitations due to the manufacturing date. Validate availability through authorized distributors or secondary market suppliers.

Selection Notes

Select this component when a low-cost, unidirectional asynchronous FIFO is required for moderate speed applications up to 33.3 MHz. The 256x9 word depth suits small buffer requirements. Consider the 32-PLCC package constraints for surface mount assembly. Verify that the 80mA current consumption fits the thermal budget. Compare against newer high-speed alternatives if latency below 20ns is critical.

Part Context

This part belongs to the Renesas 7200 series of asynchronous FIFO memories. It shares architectural similarities with other members like the 7200L15TPGI but differs in package type and speed grade. The 7200 series provides standard parallel interface solutions for legacy and industrial designs requiring reliable data buffering without complex protocol overhead.

Replacement Considerations

The 7200L12JG is listed as a manufacturer upgrade alternative. Verify pin compatibility and electrical specifications before substitution.
