What this document says about grade

This ordering code lists a -25°C to +85°C operating range only; we tag it Extended accordingly. The document’s page header names the broader product family with a vehicle-grade qualifier, but the same document explicitly states its parts are not qualified for that use unless individually designated, and this SKU carries no such qualification statement. We therefore make no vehicle-grade claim for it and log the header/disclaimer mismatch for the manufacturer.

Provenance

Every figure above is taken from Rayson “200b x16/x32 LPDDR4/LPDDR4X SDRAM” Rev D (3/2020), 305 页 (ordering-code chart and the per-package density table). We link no public datasheet because our copy has not been byte-verified against a manufacturer-hosted file.
