What Is H9TQ27ABJTMC?
H9TQ27ABJTMC (also listed as H9TQ27ABJTMCUR-KUM) is a part number for an SK hynix eMCP (embedded Multi-Chip Package) memory device. It combines 32 GB of eMMC NAND flash storage with 24 GB of LPDDR3 mobile DRAM in a single FBGA-221 package operating at 3.3 V. The "eMCP" designation means the storage and memory dies are stacked and packaged together, which saves board space and simplifies routing compared to separate eMMC and DRAM chips.
Why eMCP and eMMC Matter in Embedded Systems
Packaged memory like this is common in space-constrained designs - smartphones, tablets, handheld terminals, point-of-sale devices and compact embedded boards. The integrated approach reduces component count, shortens trace lengths and lowers power consumption, which matters in fanless and passively cooled systems. For industrial deployments, the key attributes are wide operating temperature tolerance, long-term availability and predictable write endurance. Designers selecting a memory package should always confirm the exact suffix and revision, because pinout, density and speed grade can differ between closely related part numbers.
eMCP vs. Socketed Storage in Industrial PCs
| Aspect | eMCP / eMMC (soldered) | SSD (socketed, e.g. M.2 or 2.5") |
|---|---|---|
| Form factor | Single BGA package | Separate module |
| Typical capacity | 8–64 GB | 128 GB – 4 TB |
| Serviceability | Not field-replaceable | Field-replaceable |
| Vibration/shock resistance | Very high (no connector) | High, connector-dependent |
| Best fit | Compact, sealed, low-power devices | Industrial PCs, kiosks, edge servers |
Design and Sourcing Considerations
When a product is built around a soldered memory package, the bill of materials is fixed at manufacture, so buyers should verify that the supplier can guarantee supply for the expected service life of the equipment. Where a design needs larger capacity, easier upgrades or a replaceable boot drive, an industrial PC with a standard M.2 or 2.5-inch SSD bay is usually the more practical choice. Matching the storage architecture to the deployment - sealed handheld versus rack-mounted controller - is the single most useful decision early in a project.
Thinvent Products Built for Industrial Storage Needs
Thinvent's industrial PC range, including the IPC series, is designed around serviceable, standard storage rather than soldered memory packages, so field replacement and capacity upgrades stay straightforward. Models such as the IPC3 pair Intel Core i3-1215U processors with DDR4 RAM and SSD storage, and are offered with Windows 11 Pro, Windows 11 IoT, Linux or DOS, plus optional serial ports for machine and instrument connectivity. If you need help choosing between a compact embedded design and a serviceable industrial PC, Thinvent's team can advise on the right configuration for your application.
