What Is "hqhp53aecmmd"?
Queries like "hqhp53aecmmd" are partial part markings that typically refer to Samsung eMCP and UFS embedded memory packages in BGA form factors. The closely related marking H9HQ53AECMMD identifies a Samsung eMCP (embedded Multi-Chip Package) that combines 64GB of NAND flash storage with 48MB (or similar low-capacity) LPDDR4 DRAM in a single BGA254 package. The "HQ" prefix in Samsung's memory part numbering generally denotes the product family, while the trailing characters encode capacity, die revision and package type.
These chips matter because they pack both storage and working memory into one soldered-down component. That saves board space, reduces trace length and power draw, and improves signal integrity — all of which are valuable in compact embedded designs.
Key Technical Characteristics
eMCP and UFS packages such as the H9HQ53AECMMD family are built around a few defining traits:
| Attribute | Typical Value |
|---|---|
| Package | BGA254 (solder-down, no socket) |
| Storage | 64GB NAND flash (UFS or eMMC interface) |
| DRAM | LPDDR4 / LPDDR4X, low capacity |
| Interface | UFS or eMMC, high-speed serial |
| Power | Low-power mobile/embedded voltage rails |
| Operating Range | Extended temperature variants available |
The UFS interface is significantly faster than legacy eMMC, with command queuing that improves random read/write performance — important for boot time and database-style workloads. Because the DRAM and NAND share one package, thermal behaviour and power sequencing must be designed carefully.
Where These Packages Are Used
Integrated memory packages of this type appear in industrial control boards, automotive infotainment and telematics units, robotics controllers, handheld terminals, point-of-sale devices, and IoT gateways. Anywhere a design needs permanent storage plus a small working memory in a rugged, space-constrained footprint, a soldered eMCP or UFS package is a common choice. They are also frequently encountered during board-level repair and component sourcing, which is why part-number queries are so common.
Important Note on Sourcing and Identification
Part markings on BGA memory are often abbreviated, and similar-looking codes can denote different capacities or die revisions. Before ordering replacements, always verify the full manufacturer part number, package code and capacity suffix against the original device datasheet. Counterfeit or re-marked memory packages are a known risk in the secondary market, so buy through traceable channels and confirm electrical compatibility rather than relying on a partial code alone.
Thinvent Industrial Computers Built for Embedded-Grade Reliability
Thinvent designs mini PCs, thin clients, industrial PCs and all-in-one systems for exactly the environments where embedded memory packages like these are used — factories, kiosks, vehicles, retail floors and remote sites. Our systems pair Intel® processors with soldered or socketed memory configurations, fanless thermal designs, wide-input power adapters and options for Windows 11 IoT, Windows 11 Pro, Ubuntu Linux or a no-OS configuration. If you are specifying a controller, gateway or terminal that must survive dust, heat and continuous operation, Thinvent's industrial range is built for that duty cycle.
