H5CG48AGBDX018

The H5CG48AGBDX018 is a 16 Gb DDR5 SDRAM component from SK hynix (A-die), organized 2Gb x 8 (x8). It belongs to a single SK hynix component datasheet whose ordering table (section 1.1) lists six orderable codes spanning the x4, x8 and x16 organizations of the 16Gb A-die; this page publishes the x8 product at the DDR5-5600 grade.

Key figures

• Density 16 Gb (document description line: “are a 16Gb DDR5 DRAM”).
• Organization 2Gb x 8 (x8 configuration in the ordering table).
• Speed grade GB = DDR5-5600, tCK 0.357 ns, CAS latency 16, CL-tRCD-tRP 46-45-45.
• Package 82ball FBGA for the x4 and x8 organizations.
• Temperature encoding: the D position of this code prints CT (0~95°C) — a commercial case-temperature range. Supply voltage VDD/VDDQ = 1.1V.

Reading the code

GB here is a speed bin; the CT behind the D position is a temperature range. The datasheet carries no reliability-certification or vehicle-grade statement, and none is claimed here.

Full ordering code and packaging suffix

The datasheet ordering table prints this code with a trailing N as H5CG48AGBDX018N (the trailing position in that table denotes the packaging form). Supplier-reported spot listings on this site carry the trailing position either as N (tray) or R (tape-and-reel) — for example H5CG48AGBDX018N and H5CG48AGBDX018R. Those are the same die and speed bin at different packaging forms, handled at the spot-listing layer; the library page keeps the base ordering code.
