7207L35LB8

Overview

The Renesas Electronics Corporation 7207L35LB8 is an asynchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 288K bits, organized as 32K words by 9 bits. The component supports a data rate of 22.22MHz with an access time of 35ns. It operates on a single supply voltage ranging from 4.5V to 5.5V and draws a maximum supply current of 120mA. The device utilizes a 32-pin LCC (J-lead) package for surface-mount installation.

Feature Summary

• Supports asynchronous read and write operations with simultaneous data handling capabilities
• Includes auto-retransmit functionality allowing reset of the read pointer to its initial position
• Provides status flags including Empty, Half-Full, and Full indicators to manage data flow
• Features fully expandable architecture supporting expansion by both word depth and bit width

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications between components operating at different clock speeds
• Data acquisition systems needing temporary storage before processing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt, ensuring no damage to the 32-LCC J-lead pins. Check moisture sensitivity level handling procedures during storage and assembly to prevent internal damage.

Selection Notes

Select this component when designing systems requiring unidirectional asynchronous data buffering with specific 32K x 9 organization. Ensure the design environment supports 5V logic levels and accommodates the 35ns access time constraints. Verify that the PCB layout supports the 32-pin PLCC/LCC footprint dimensions of 14mm by 11.46mm. Consider thermal management within the specified commercial temperature range of 0°C to 70°C.
