7207L35LB

Overview

The Renesas 7207L35LB is an asynchronous FIFO memory IC featuring a storage capacity of 288 kbit organized as 32K x 9. It operates with a maximum access time of 35 ns and supports data rates up to 22.22 MHz. The device functions within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum supply current of 120 mA. It utilizes a unidirectional bus architecture and is housed in a 32-LCC (J-lead) surface-mount package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• CMOS parallel interface technology

Applications

• Data buffering between asynchronous logic systems
• Clock domain crossing interfaces
• High-speed serial-to-parallel conversion buffers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Ensure the specific suffix LB corresponds to the required package variant and electrical specifications for your design requirements.

Selection Notes

Select this component when designing systems requiring unidirectional asynchronous data buffering with a 9-bit word width. Verify that the 35 ns access time meets the system timing constraints. Ensure the operating temperature range and voltage specifications align with the target application environment before finalizing the part selection.

Part Context

This component belongs to the 7207 series of asynchronous FIFOs manufactured by Renesas Electronics. It shares architectural similarities with other parts in the family but is distinguished by its specific 35 ns speed grade and 9-bit data width configuration. The device represents a specialized solution for parallel data handling applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative asynchronous FIFOs from the same manufacturer series only if they match the pinout, voltage, and performance specifications exactly.
