MT46H64M32LFMA-5 IT:A TR

Memory IC Overview

The MT46H64M32LFMA-5 IT:A TR is a 2Gb Mobile Low-Power DDR SDRAM manufactured by Micron Technology. It features a 64 Meg x 32 organization with four internal banks and operates at a maximum clock rate of 200 MHz, providing an access time of 5.0 ns. The device utilizes a 168-ball WFBGA (12mm x 12mm) package, designated by the MA suffix. It supports a VDD/VDDQ supply voltage range of 1.70V to 1.95V and is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Internal pipelined double data rate architecture enabling two data accesses per clock cycle
• Bidirectional data strobe per byte of data with edge-aligned read and center-aligned write alignment
• Supports temperature-compensated self refresh, partial-array self refresh, and deep power-down modes
• Features programmable burst lengths and selectable output drive strength

Memory IC Applications

• Mobile handheld devices requiring low-power memory solutions
• Industrial embedded systems operating in wide temperature ranges
• Portable consumer electronics utilizing mobile LPDDR interfaces

Memory IC Procurement Notes

Verify the specific ordering suffixes against official Micron documentation to ensure correct package type, speed grade, and temperature rating. Confirm that the MA package code corresponds to the required 168-ball WFBGA form factor. Check current product status as mobile memory components may undergo lifecycle changes or obsolescence notices.

Memory IC Selection Notes

Select this component when a 2Gb capacity with a 32-bit data bus width is required for mobile applications. Ensure the design accommodates the 1.8V LVCMOS-compatible inputs and the specific 168-ball WFBGA footprint. Verify compatibility with the internal quad-bank architecture and supported command sets for the target system controller.

Memory IC Part Context

This part belongs to the Micron MT46H series of Mobile LPDDR SDRAMs. The '64M32' designation indicates a 64 Meg x 32 configuration, totaling 2Gb density. The 'LF' addressing denotes JEDEC-standard organization, while 'IT' specifies the industrial temperature range. The '-5' speed grade defines the 200 MHz operational limit.

Memory IC Replacement Considerations

Compatible substitutes within the same family include variants with different package codes such as JV (168-ball VFBGA) or KQ (168-ball WFBGA), provided the electrical specifications and pinout remain identical. Speed grades like -54 or -6 offer lower clock rates but maintain functional compatibility.
