The HY5DU121622DTP-D43I-C is a 128Mbit DDR SDRAM manufactured by Hynix Semiconductor. It is similar to the HY5DU121622CTP-D43-C, but the "DTP" and "D43I" likely indicate different packaging and an extended (industrial) temperature range, respectively. The "C" may still denote the same commercial use.

Applications

• Industrial Control Systems: Used for data logging, control processing and program storage in industrial systems requiring tolerance to temperature variations.
• Embedded Systems: Suitable for embedded applications in transportation, industrial automation or other environments requiring stable operation across a range of temperatures.
• Networking Equipment: Employed in networking hardware designed to operate reliably outside of climate-controlled environments.

Features

• 128Mbit Capacity: Memory capacity suited to embedded systems and some networking devices.
• DDR Technology: Provides good data transfer rates suitable for many applications.
• Double Data Rate: Increases effective bandwidth by transferring data on both clock edges.
• JEDEC Standard Compliance: Ensures compatibility and interoperability with supporting hardware.
• Extended Temperature Range: Designed to maintain functionality across a wider range of ambient temperatures than standard components.

Benefits

• Reliable Operation: Maintains stable performance in applications subject to temperature fluctuations.
• Increased System Availability: Reduces the risk of memory failure in challenging environments.
• Lower Total Cost of Ownership: Minimizes maintenance and downtime associated with temperature-related component failures.

Additional Details

The voltage requirements are likely similar to other DDR SDRAMs in this family (around 2.5V). The “DTP” in the part number suggests a different packaging that might offer improved thermal characteristics or reliability. This component is aimed at applications needing reliable memory in environments outside typical office or home conditions.
