7206L15TP

Overview

The Renesas Electronics Corporation 7206L15TP is an asynchronous FIFO memory integrated circuit designed for multiprocessing and rate buffering applications. It features a storage capacity of 144K bits, organized as 16K words by 9 bits. The device supports unidirectional data transfer with a maximum clock frequency of 40MHz and an access time of 15ns. Operating within a supply voltage range of 4.5V to 5.5V, it draws a maximum supply current of 120mA. The component is housed in a 28-pin PDIP package suitable for through-hole mounting and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for efficient data handling
• Includes retransmit capability allowing reset of the read pointer to its initial position
• Utilizes Full and Empty status flags to prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring high-speed data exchange
• Rate buffer applications between components operating at different speeds
• Data acquisition systems needing temporary storage buffers

Procurement Notes

Verify component authenticity due to discontinuation status. Confirm package integrity and pin alignment against original specifications. Check for moisture sensitivity damage if stored improperly. Ensure replacement parts maintain functional compatibility with existing system designs. Review manufacturer notices for any specific handling or substitution guidelines.

Selection Notes

Select this component when asynchronous operation with 15ns access speed is required. Consider the 16K x 9 organization for specific data width needs. Evaluate the 28-pin PDIP package for through-hole assembly requirements. Verify that the 40MHz maximum clock frequency meets system timing constraints. Confirm power supply stability within the specified voltage range.

Part Context

This part belongs to the 7200 series of FIFO memories from Renesas Electronics. It is functionally compatible with the broader 720X family, ensuring design continuity. The device represents a legacy solution for high-speed buffering tasks. Its discontinuation reflects shifts toward newer memory technologies. Engineers may encounter this part in established industrial and communication equipment designs.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify pinout and electrical parameter compatibility before integration. Ensure mechanical dimensions match existing PCB footprints. Review functional differences to confirm system performance requirements are met.
