MT41K256M16HA-125:E

Memory IC Overview

The Micron MT41K256M16HA-125:E is a 4Gb DDR3L SDRAM with a 256 Meg x 16 organization and eight internal banks. It operates at VDD = VDDQ = 1.35V (1.283–1.45V) and supports backward compatibility to 1.5V. The -125 speed grade provides a maximum data rate of 1600 MT/s with CL=11 timing. It utilizes a 96-ball FBGA package (Rev. E, HA marking) and supports commercial temperature ranges from 0°C to +95°C.

Memory IC Feature Summary

• Low voltage operation at 1.35V with backward compatibility to standard 1.5V applications
• Supports differential bidirectional data strobes and nominal dynamic on-die termination
• Features programmable CAS latencies and selectable burst lengths via mode register set
• Includes write leveling, multipurpose registers, and output driver calibration

Memory IC Applications

• High-performance computing systems requiring low power consumption
• Consumer electronics utilizing DDR3L memory interfaces
• Industrial equipment operating within commercial temperature limits

Memory IC Procurement Notes

Verify the specific ordering suffix against official Micron catalogs to confirm package dimensions and revision status. Ensure the procurement source provides documentation confirming the component meets the specified electrical parameters for the -125 speed grade and Rev. E die revision.

Memory IC Selection Notes

Select this component when a 4Gb capacity with a 16-bit data bus width is required. The -125 speed grade is suitable for systems targeting 1600 MT/s throughput. Confirm that the application environment remains within the 0°C to +95°C commercial temperature range defined for this part number.

Memory IC Part Context

This device belongs to the Micron MT41K family of DDR3L SDRAMs. It shares architectural similarities with other members like the MT41K256M16TW-107 but differs in speed grade and package variant. The HA marking specifically identifies the 96-ball FBGA package configuration used in this series.

Memory IC Replacement Considerations

Compatible substitutes include the MT41K256M16HA-107 or MT41K256M16HA-093, provided the system can accommodate their respective higher speed grades.
