7201LA50DB

Overview

The Renesas Electronics Corporation 7201LA50DB is a 512 x 9 asynchronous FIFO memory device. It operates with a maximum access time of 50 ns and supports data rates up to 15 MHz. The component functions as a dual-port FIFO memory that loads and empties data on a first-in/first-out basis, utilizing Full and Empty flags to prevent data loss. It is designed for 5.0 V operation and is housed in a 28-pin Ceramic Dual In-Line Package (CerDIP).

Feature Summary

• Asynchronous dual-port architecture enabling independent read and write clock domains.
• First-in/first-out data loading and emptying mechanism.
• Hardware status flags including Full and Empty indicators to manage data flow integrity.

Applications

• Data buffering between asynchronous logic systems.
• Interface bridging between components operating at different clock speeds.
• Temporary storage in high-speed digital signal processing chains.

Procurement Notes

Verify the specific package variant, as the 7201LA50DB is identified as a 28-pin CerDIP component. Confirm RoHS compliance status, as sources indicate non-compliance for this specific part number. Check product lifecycle status, as it may be classified as obsolete or end-of-life. Ensure compatibility with existing 5.0 V power supply designs and 28-pin footprint requirements before procurement.

Selection Notes

Select this component when a 512-word by 9-bit depth is required for asynchronous data buffering. It is suitable for applications needing 50 ns access times and 15 MHz throughput. Consider the 28-pin CerDIP package constraints and 5.0 V operating voltage. Evaluate alternatives if lead-free compliance or surface-mount packaging is mandatory, as this part uses ceramic DIP technology.

Part Context

This device belongs to the 7201 series of CMOS parallel FIFO memories manufactured by Renesas Electronics. It shares architectural similarities with other parts in the family but is distinct in its specific 50 ns speed grade and 28-pin ceramic package configuration. The series is designed for reliable data storage in industrial and communication equipment requiring robust FIFO functionality.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully when considering generic replacements for obsolete ceramic DIP components.
