MT47H64M16HW-3 IT:H

Memory IC Overview

The MT47H64M16HW-3 IT:H is a Micron DDR2 SDRAM component with a 1 Gbit density and 16-bit data bus width. It utilizes an 84-pin TFBGA package and operates at a maximum clock frequency of 333 MHz. The device supports a 4n-bit prefetch architecture and features eight internal banks for concurrent operations. Electrical specifications include a supply voltage range of 1.7 V to 1.9 V and an industrial temperature operating range from 0°C to +85°C.

Memory IC Feature Summary

• Supports differential data strobe (DQS, DQS#) and duplicate output strobe (RDQS) options for x8 configurations.
• Features on-die termination (ODT) and adjustable data-output drive strength.
• Includes a DLL to align DQ and DQS transitions with the clock signal.

Memory IC Applications

• Industrial embedded systems requiring high-speed memory access
• Consumer electronics utilizing DDR2 SDRAM interfaces
• Networking equipment with standard JEDEC I/O requirements

Memory IC Procurement Notes

Verify the specific suffix 'IT:H' against official Micron documentation to confirm the exact temperature grade and packaging variant. Ensure compatibility with existing PCB layouts designed for the 84-pin TFBGA form factor. Confirm that the 1.8V ±0.1V power supply rails meet the strict electrical requirements for reliable operation within the specified industrial temperature range.

Memory IC Selection Notes

Select this component when a 1 Gbit capacity with a 16-bit interface is required for space-constrained designs. The industrial temperature rating makes it suitable for environments exceeding standard commercial limits. Consider the 333 MHz speed grade if higher bandwidth is not critical, as it offers a balance between performance and power consumption for general-purpose applications.
