Additional Details

The MT47H256M8HG-37E:A typically operates at a specific voltage (e.g., 1.8V) and has defined timing parameters, including clock frequency, CAS latency (CL), and tRCD (RAS-to-CAS Delay). It is commonly packaged in a FBGA (Fine-pitch Ball Grid Array) for surface mounting. The '-37E' likely refers to a specific speed grade or timing configuration, and ':A' could indicate a revision. Consult the official Micron datasheet for detailed specifications, including timing diagrams, electrical characteristics, and thermal management guidelines. Proper PCB layout is crucial for achieving optimal performance and signal integrity with DDR2 SDRAM.
