Additional Details

The MT47H16M16FG-5E IT:B operates at a voltage of 1.8V. It is packaged in a FBGA (Fine-pitch Ball Grid Array). The -5E indicates a specific speed grade, corresponding to a clock frequency of 400 MHz (800 MT/s data rate). The IT indicates industrial temperature grade, meaning it can operate between -40°C and +85°C, and the :B signifies a specific revision or manufacturing lot. The device supports burst lengths of 2, 4, and 8. It also includes features such as write latency of 0, 1, 2, or 3 clock cycles. The refresh interval is typically 7.8 μs. The power consumption varies depending on the operating frequency and activity, but it is designed for relatively low power operation compared to older SDRAM technologies.

This DDR2 SDRAM chip is a crucial component in systems requiring high-performance memory, offering a balance of speed, capacity, and power efficiency.
