MT46H128M16LFB7-5 IT:B TR

Memory IC Overview

The MT46H128M16LFB7-5 IT:B TR is a 2Gb Automotive Low-Power DDR SDRAM manufactured by Micron Technology. It features a 128 Meg x 16 organization with four internal banks and operates at a maximum clock rate of 200 MHz with an access time of 5.0 ns. The device utilizes a 60-ball VFBGA package (10mm x 10mm) and supports a voltage range of 1.70V to 1.95V for both VDD and VDDQ. Designed for automotive applications, it includes temperature-compensated self-refresh and partial-array self-refresh capabilities.

Memory IC Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to ensure compatibility with required speed grades and package types. Confirm that the automotive temperature rating aligns with the target application environment. Check for any design revision updates that may affect pinout or electrical characteristics before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when automotive certification and low-power operation are critical requirements. Ensure the system design accommodates the 1.8V I/O levels and differential clock inputs. Consider the 60-ball VFBGA footprint constraints during PCB layout. Verify that the controller supports the necessary burst lengths and bank interleaving modes for optimal performance.

Memory IC Part Context

This part belongs to Micron's Mobile LPDDR family, specifically tailored for automotive environments. It shares architectural similarities with other 2Gb LPDDR devices but distinguishes itself through extended temperature ranges and rigorous automotive testing standards. The -5 speed grade indicates a 200 MHz operational capability, suitable for bandwidth-intensive mobile applications.

Memory IC Replacement Considerations

Direct replacements must match the 2Gb capacity, x16 width, and 60-ball VFBGA package. Verify that alternative parts support the same 200 MHz speed grade and automotive temperature ratings. Cross-reference mode register settings and initialization sequences to ensure functional compatibility.
