Additional Details:

The HY5DU12822DFP-D43 conforms to JEDEC standards for DDR SDRAM. The 128M x 2 x 4 banks organization describes the internal memory architecture. The -D43 speed bin specifies the maximum operating frequency and associated timing parameters. Refer to the Hynix datasheet for this specific part number for detailed timing information (CAS latency, RAS-to-CAS delay, precharge time, etc.). FBGA packaging offers improved thermal performance and allows for higher component density. This memory is suitable for applications where a balance of performance, cost-effectiveness, and power efficiency is important. The standard DDR interface simplifies integration into existing system designs.
