• DDR2 architecture
• Data transfer rates up to 533 Mbps
• Differential clock inputs (CK, /CK)
• Double data rate interface
• On-die termination (ODT)

Benefits:

• High bandwidth for demanding applications
• Improved system performance due to faster data transfer rates.
• Reduced power consumption compared to older SDRAM technologies.

• Increased memory density for smaller system footprints.

Additional Details:

The MT47H32M16BN-37E DDR2 SDRAM utilizes a double data rate interface, transferring data on both the rising and falling edges of the clock signal. The device requires a 1.8V power supply for the memory core and a separate power supply for the I/O interface. On-die termination (ODT) reduces signal reflections and improves signal integrity at high frequencies. The '37E' suffix typically indicates the speed grade and timing parameters of the memory, which are crucial for proper system operation. The datasheet provides detailed information on timing specifications, refresh rates, and power consumption. Proper thermal management is important for reliable operation at high frequencies. JEDEC standards define the DDR2 SDRAM specifications and operating protocols. The part is available in FBGA packages.
