The H54G46CYRBX267N is an SK Hynix LPDDR4X mobile SDRAM from the H54G series, supplied in a 200-ball FBGA surface-mount package. It provides 16Gb of density, equivalent to 2GB, on a 16-bit data bus at a rated 2133M Hz. The device operates from a 1.1V supply with rail ranges of 1.06V-1.17V and 1.7V-1.95V. SK Hynix specifies the H54G46CYRBX267N over an operating temperature range of -40C to +85C.

A x16 LPDDR4X device is normally deployed as one half of a 32-bit memory subsystem, so designers place two of them to fill an SoC channel or use one where a narrow bus is sufficient. Systems that specify this configuration include automotive telematics and body modules, industrial gateways, smart meters and grid equipment, IP cameras, and networking hardware where cost and pin count matter more than peak bandwidth. The -40C rating on the H54G46CYRBX267N supports cold-start requirements outside conditioned enclosures. Buyers are typically industrial and automotive-adjacent OEMs plus module vendors sourcing an SK Hynix-qualified LPDDR4X alternative to their primary memory supplier.
