7200L15TPGI

Overview

The Renesas Electronics Corporation 7200L15TPGI is an asynchronous FIFO memory integrated circuit manufactured in a 28-PDIP package. It features a storage capacity of 2.25K bits, organized as 256 words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 40MHz and an access time of 15ns. It operates on a single 5V supply voltage ranging from 4.5V to 5.5V, with a maximum supply current of 80mA. The component is designed for through-hole mounting and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles without clock synchronization constraints.
• Unidirectional bus architecture providing dedicated paths for input and output data flow.
• Retransmit capability allowing the reset of the read pointer to its initial position via a control signal pulse.
• Full expandability supporting modifications to both word depth and bit width configurations.

Applications

• Multiprocessing systems requiring data buffering between asynchronous processors.
• Rate matching applications where data streams operate at different speeds.
• Digital signal processing interfaces needing temporary data storage during transfer operations.

Procurement Notes

Verify component authenticity due to discontinuation status. Confirm RoHS3 compliance and check for specific assembly site variations documented in Product Change Notices. Ensure compatibility with existing PCB footprints for the 28-PDIP package. Validate that the unidirectional interface meets system requirements before procurement.

Selection Notes

Select this component when asynchronous buffering with 9-bit data width is required. The 15ns access time suits moderate-speed digital interfaces. Consider the 28-PDIP package for through-hole assembly needs. Evaluate the 256-word depth against buffer size requirements. Verify power consumption limits align with system thermal design specifications.

Part Context

This part belongs to the IDT 7200 series of asynchronous FIFO memories. The series offers various densities and speed grades. The 7200L15 variant specifically targets applications needing reliable data buffering with standard TTL-compatible logic levels. It serves as a bridge between components operating at different clock domains.

Replacement Considerations

The 7201LA12SOG is listed as a manufacturer substitute. Verify functional compatibility regarding access time and pinout before replacement. Check if the alternative meets the same environmental and electrical specifications.
