7201LA20LB

Overview

The Renesas 7201LA20LB is an asynchronous FIFO memory device with a capacity of 4.5K bits, organized as 512 words by 9 bits. It operates at a data rate of 33.3MHz with a maximum access time of 20ns. The component supports a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. It is housed in a 32-CLCC package measuring 13.97x11.43mm and functions within a temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous dual-port architecture for independent read and write clock domains
• Utilizes Full and Empty flags to manage data flow and prevent overflow or underflow conditions
• CMOS technology ensures low power consumption and high-speed operation

Applications

• Data buffering between systems operating at different clock speeds
• Interface bridging in telecommunications equipment
• Digital signal processing applications requiring temporary data storage

Procurement Notes

Verify the specific suffix LB against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS status as historical records indicate non-compliance. Ensure the source provides valid traceability for this discontinued component series.

Selection Notes

Select this part when a 512x9 asynchronous buffer is required with 20ns performance. Compare against the 7201LA15JGI8 for faster access times or other 7201 series variants for different capacities. Verify that the 32-CLCC footprint matches the target PCB design constraints.

Part Context

This component belongs to the Renesas 7201 series of asynchronous FIFOs. It shares architectural similarities with parts like the 7201LA20J8 but differs in packaging. The series is designed for parallel data transfer applications where clock domain crossing is necessary.

Replacement Considerations

The IDT7201LA20J8 is listed as an alias for this component family. Verify electrical and mechanical compatibility before substitution.
