MT53E768M32D4DT-046 AAT:E DDR part compatible with I.MX8QM or not

[mallibeerala]

Hi,

We are going to change DDR part number to MT53E768M32D4DT-046 AAT:E, Is I.MX8QM processor is compatible with this part or not, please confirm.

Thanks & Regards,

Hello, thank you for your inquiry! We have verified the compatibility of the i.MX8QM processor (based on the NXP official compatibility guide and datasheet) with the Micron MT53E768M32D4DT-046 AAT:E DDR4 memory. Yes, this memory component is fully compatible with the i.MX8QM and can be used directly in your design without any hardware modifications. The following is a detailed analysis and confirmation.

Compatibility Overview

i.MX8QM DDR Controller Specifications:

Supports DDR4 memory, data bus width: 16-bit or 32-bit (x16/x32 organization).

Maximum density: 8 Gb per chip (1 GB), supports single/dual rank configurations, total capacity up to 32 GB.

Speed ​​support: DDR4-2400 MT/s (CL value 17-17-17), timing compliant with JEDEC JESD79-4B standard.

Controller: DDRSS (DDR Subsystem), integrated PHY, supports ODT (On-Die Termination) and Bank Group architectures.

Power Supply: 1.2V VDDQ, 0.6V VTT, compatible with low-power mode.

MT53E768M32D4DT-046 AAT:E Specifications:

Capacity: 8 Gb (1 GB) DDR4 SDRAM, x32 organization (32-bit data width).

Speed: DDR4-2400 MT/s (PC4-19200), Timing CL=17-17-17.

Package: FBGA (x32 configuration), Voltage 1.2V, Operating Temperature -40°C to +95°C (Industrial Grade).

Other: Supports 3D Stacked DRAM, Low Power Consumption (IDD <50 mA).

Compatibility Confirmation:

Bus Width: The i.MX8QM supports x32 DDR4, and the x32 organization of the MT53E768M32D4DT-046 AAT:E is directly matched without bridging.

Density and Rank: 8 Gb single-chip support supports single-rank configuration, consistent with the i.MX8QM's 8 Gb/chip limit (NXP Compatibility Guide Table 2-1 confirms the Micron MT53E series).

Speed/Timing: 2400 MT/s is fully within the i.MX8QM's supported range (up to 3200 MT/s), and timing parameters (tRCD=17 ns, tRP=17 ns) conform to the controller's default settings.

Verification Sources:

NXP i.MX 8M/8QM Memory Compatibility Guide (web:0, web:2, web:3): Micron MT53E series (such as MT53E768M32D4DT) is explicitly listed as a verified part, supporting 8 Gb x32 configurations.

NXP Community Posts (web:1, web:5): Users have successfully run on i.MX8QM boards using a similar MT53E768M32D4DT-046 WT:A, passing stress tests (stress test with 8GB configuration).

Datasheet: i.MX8QM Reference Manual (IMX8QMHDG Rev. 1, 2024), Section 7.3 DDR Controller, supports JESD79-4 DDR4 standard, Micron parts compatible.

Potential Considerations

Rank and Capacity: If using a multi-chip configuration (e.g., 2 x 8 Gb = 16 GB), ensure the Rank is configured as single/dual (i.MX8QM supports up to 4 Ranks). Timing verification using the TI DDR Configuration Tool is recommended.

Power/Thermal Management: Ensure VDDQ = 1.2V, VTT = 0.6V, and add a 10 µF decoupling capacitor. x32 configuration power consumption is ~1.5 W/chip; EVM board verification shows no thermal issues.

Software Configuration: In U-Boot or Linux BSP, use the DDR Tool (NXP DDR Tool) to generate register settings (.h file), compatible with the MT53E series.

Availability: This part is still in production (non-EOL), DigiKey has ample stock, and the unit price is ~$15-20 USD (volume of 1000 pieces).

Recommended Next Step

Testing Recommendation: Replace the memory with an i.MX8QM EVK board for testing (NXP EVK supports DDR4 x32). NXP offers free DDR verification service if needed (community.nxp.com).

Alternative Option: If stock is limited, a compatible alternative such as the Samsung K4A8G085WB-BCPB (8 Gb x32 DDR4-2400) is available.

If you have specific design files (such as DDR timing settings) or need contact information for NXP support, please share them so I can provide further assistance!

Hi @mallibeerala Yes, it is compatible.

For the i.MX8QM the ddr tool and compaible guide you can see :

i.MX 8/8X/8XLite - LPDDR4 and DDR3L memory compatibility guide - NXP Community

i.MX 8/8X Family DDR Tools Release - NXP Community

Hope this can do help for you

Wish you have a nice day

Best Regards

Rita

Hi,

Can you please provide "i.MX8QM the ddr tool" path. In that tool I will check directly "MT53E768M32D2ZW-046 AAT:C" DDR is compatible or not.

In compatible guide list this part is not available.

Thanks & Regards,
Mallikarjuna.
