72201L25J

Overview

The Renesas Electronics Corporation 72201L25J is a synchronous First-In, First-Out (FIFO) memory device. It features a storage organization of 256 words by 9 bits, providing a total capacity of 2.25 kilobits. The component operates with a maximum clock frequency of 40 MHz and has an access time of 15 ns. It utilizes a single 5.0 V power supply and employs a unidirectional bus architecture. The integrated circuit is housed in a 32-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Feature Summary

• Synchronous data buffering with dedicated clocked read and write controls
• Unidirectional data flow architecture for streamlined interface connections
• High-speed operation supporting up to 40 MHz clock frequencies

Applications

• Graphics data buffering systems
• Local area network interface modules
• Interprocessor communication links

Procurement Notes

Verify the specific manufacturing source and lot traceability before procurement. Confirm RoHS compliance status as historical records may vary. Check for moisture sensitivity level requirements during storage and handling. Ensure the PLCC-32 footprint matches the target PCB design. Validate that the 5.0V logic levels align with the system voltage specifications.

Selection Notes

Select this component when a compact synchronous FIFO with a 9-bit width is required. The 256-word depth suits moderate buffering needs without excessive memory overhead. The 15 ns access time supports high-throughput applications. Consider the PLCC package constraints for board space and thermal management. Verify compatibility with existing 5V logic families in the design.

Part Context

This part belongs to the Renesas SyncFIFO family, which provides reliable data buffering solutions. The 72201 series specifically targets applications requiring simple, high-speed memory interfaces. These devices are commonly used in embedded systems where deterministic data transfer timing is critical. The family offers various densities and speeds to match different performance requirements.

Replacement Considerations

Check for direct pin-compatible replacements within the same manufacturer's portfolio. Verify that alternative parts maintain the 256x9 organization and 5.0V operating voltage. Ensure the replacement supports synchronous operation with similar access times. Confirm package compatibility if physical retention is necessary.
