7202LA30TDB

Overview

The Renesas 7202LA30TDB is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates at a maximum data rate of 25MHz with a 30ns access time. The component supports unidirectional bus operation and functions within a supply voltage range of 4.5V to 5.5V. It features relay capability and is housed in a 28-CDIP package suitable for through-hole mounting.

Feature Summary

• Asynchronous first-in/first-out data buffering
• Full and empty flag status indicators
• Relay capability support

Applications

• Data buffering between asynchronous clock domains
• Interface bridging in high-speed digital systems
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix TDB confirms the 28-CDIP package and through-hole configuration. Confirm RoHS compliance status as historical records indicate non-compliance for some variants. Check for active substitute part numbers due to potential obsolescence. Validate moisture sensitivity level requirements for your assembly process.

Selection Notes

Select this component when a 1K x 9 asynchronous FIFO with 30ns speed is required. Ensure the system design accommodates the 28-CDIP through-hole form factor. Verify that the 4.5V to 5.5V operating voltage aligns with the target logic levels. Consider the 25MHz maximum frequency against system timing constraints.

Part Context

This device belongs to the Renesas 7202L series of asynchronous FIFO memories. It provides reliable data buffering for applications requiring decoupling of data transfer rates. The 7202L series is known for its robust performance in industrial and commercial electronic environments.

Replacement Considerations

Public documentation indicates this product is obsolete. Verify official substitute part numbers from Renesas before procurement.
