7202LA30LB

Overview

The Renesas Electronics Corporation 7202LA30LB is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 9K bits, organized as 1K words by 9 bits. It operates with a maximum data rate of 25MHz and provides an access time of 30ns. The device supports unidirectional bus directionality and includes relay capability. It functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum supply current of 100mA. The component is housed in a 32-LCC package measuring 11.43x13.97 mm and is rated for an operating temperature range of -55°C to 125°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• Relay capability support
• Extended industrial temperature range operation

Applications

• Data buffering between asynchronous systems
• Clock domain crossing interfaces
• High-speed data acquisition systems

Procurement Notes

Verify the specific suffix LB against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS status, as this part may not meet current environmental directives. Check for active obsolescence notices or production discontinuation announcements from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 9K depth and 9-bit width are required for asynchronous buffering. Ensure the system design accommodates the 30ns access time and 25MHz maximum frequency limits. Verify that the 32-LCC package footprint fits the PCB layout constraints and that the wide operating temperature range meets the environmental requirements.

Part Context

This component belongs to the Renesas 7202 series of asynchronous FIFOs. It shares architectural similarities with other parts in the family but differs in speed grade and packaging. The 7202LA30LB specifically targets applications requiring robust performance in harsh environments due to its extended temperature rating and LCC packaging style.
