The HY5DU12822BT-D43 is a 256Mb DDR SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory) chip manufactured by Hynix Semiconductor. It's designed for applications requiring high-speed data transfer, such as graphics cards, and general system memory.

Applications:

• Graphics cards (entry-level and mid-range)
• Desktop and laptop computers
• Gaming consoles
• Networking devices
• Embedded systems requiring moderate memory bandwidth

Features:

• Capacity: 256Mb (128M x 2 x 4 banks)
• Data Rate: DDR (Double Data Rate)
• Clock Frequency: The "-D43" likely indicates a specific speed grade. Research suggests this refers to a 200MHz clock speed (DDR400)
• Voltage: Typically 2.5V
• Interface: Standard DDR SDRAM interface
• Operating Temperature: Commercial temperature grade
• Package: FBGA (Fine-Pitch Ball Grid Array)

Benefits:

• High Bandwidth: DDR technology allows for faster data transfer rates.
• Improved Performance: Enhances system responsiveness and overall performance.
• Lower Power Consumption: 2.5V operation contributes to energy efficiency.
• Compact Size: FBGA packaging enables a smaller footprint on PCBs.
• Reliability: Hynix is a well-known manufacturer of reliable memory products.

Additional Details:

The HY5DU12822BT-D43 adheres to JEDEC standards for DDR SDRAM. The 128M x 2 x 4 banks organization specifies the internal memory structure. The -D43 speed bin designates the maximum supported clock frequency and associated timing parameters. Consult the Hynix datasheet for this specific part number to obtain precise timing specifications (CAS latency, RAS-to-CAS delay, etc.). FBGA packaging provides better thermal performance and allows for higher density compared to TSOP packages. This memory is often used in applications where cost-effectiveness and adequate performance are important considerations. Its DDR interface simplifies integration, and its bandwidth capabilities support a variety of applications, including graphics processing and general-purpose computing.
