7201LA20DB

Overview

The Renesas 7201LA20DB is an asynchronous FIFO memory device with a capacity of 4.5K bits, organized as 512 words by 9 bits. It operates at a maximum data rate of 33.3MHz with a 20ns access time. 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 28-CDIP package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous dual-port architecture for independent read and write clock domains
• Full and Empty flag outputs to prevent buffer overflow and underflow conditions
• CMOS technology ensuring low power consumption during operation

Applications

• Data buffering between systems operating at different clock speeds
• Interface bridging in high-speed digital communication links
• Temporary storage in real-time signal processing pipelines

Procurement Notes

Verify the specific package variant, as the 7201 series includes PLCC and CDIP options. Confirm RoHS compliance status, as some variants are non-compliant. Check part status, as this model may be discontinued or obsolete depending on the manufacturing date code. Ensure the supplier provides official datasheets for electrical verification before integration.

Selection Notes

Select this component when a 512x9 word depth is required for asynchronous data transfer. The 20ns access time suits moderate-speed applications. Verify that the 28-CDIP package fits the target PCB layout. Consider alternative pin-compatible models if surface-mount packaging is preferred over through-hole DIP formats.

Part Context

This device belongs to the Renesas 7201L series of asynchronous FIFOs. It is manufactured using CMOS technology. The part is often cross-referenced with IDT equivalents. It serves as a standard solution for decoupling data streams in embedded systems requiring reliable first-in-first-out memory management.

Replacement Considerations

IDT7201LA20DB is a confirmed substitute part number. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
