7202LA15TPI

Overview

The Renesas 7202LA15TPI is an asynchronous FIFO memory device with a storage organization of 4K x 9 bits, providing a total capacity of 36 kbit. It features a unidirectional data bus and supports a maximum clock frequency of 40 MHz. The component has a typical access time of 15 ns and operates within a supply voltage range of 4.5 V to 5.5 V. Maximum power consumption is specified at 120 mA. It is housed in a 28-pin PDIP package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data transfer capability
• CMOS technology implementation

Applications

• Data buffering between different speed logic circuits
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the exact suffix 'TPI' against official Renesas documentation to confirm the specific package variant and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 28-pin DIP form factor. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check for any obsolescence notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when a 4K depth and 9-bit width are required for asynchronous buffering. The 15 ns access time suits moderate-speed applications. Consider the PDIP package only if through-hole mounting is necessary. Verify that the 40 MHz maximum frequency meets system timing requirements. Compare against other 7202L series variants if different speeds or organizations are needed.

Part Context

This part belongs to the Renesas 7202L series of CMOS parallel FIFOs. The series offers various access times and organizations to suit different interface needs. The 7202LA15TPI specifically targets applications requiring 15 ns performance in a standard DIP package. It serves as a bridge between synchronous and asynchronous systems.

Replacement Considerations

IDT7204L15TPI is a documented alias for this component. Verify pinout and electrical specifications match exactly before substitution. Other 7202L series parts may require re-evaluation of timing and capacity.
