H5CG44AGBJX018

The H5CG44AGBJX018 is a 16 Gb DDR5 SDRAM component from SK hynix (A-die), organized 4Gb x 4 (x4 width), in 82ball FBGA. It is one of six orderable codes printed in section 1.1 of the same component datasheet. Five of those six had no page on this site until this entry; the sixth already carries one (published October 2026), and the two pages do not share any figure.

Key figures

• Density: the document description line prints 16Gb DDR5 DRAM for this group of codes.
• Organisation as printed in the ordering table: 4Gb x 4. The ordering table prints one density cell and one package cell for a group of rows (merged cells): the values quoted here are that group’s printed value, and the table’s own row order puts this part number inside it.
• Package as printed in the same table: 82ball FBGA.
• Speed bin: positions 8-9 of this code read GB, and the frequency table prints DDR5-5600 against grade GB (tCK 0.357 ns, CL-tRCD-tRP 46-45-45).
• Temperature: the code’s temperature position reads J, which the decoding table prints as IT (-40~95℃).
• Supply: VDD/VDDQ = 1.1V as printed in the device features.

Full ordering code and packaging suffix

The datasheet’s ordering table prints this code with a trailing N — H5CG44AGBJX018N — that trailing position being the packaging form (N tray, R tape-and-reel). This library page keeps the base ordering code, the same convention as the sibling page published in October; the quoted row above is the manufacturer’s full printed string.

What this page does not claim

Lifecycle: left blank — the datasheet prints no product status. No reliability certification, automotive grade or vehicle qualification is stated anywhere in this document and none is claimed here. Speed bins other than GB exist in the datasheet’s frequency table; this page publishes only the bin its own code letters decode to.
