Document vs manufacturer page

The figures above are from the delivered V2.0 datasheet, which we treat as primary. The manufacturer’s public product page for this series differs on a few points and we note rather than silently reconcile them: it lists an operating range of -20°C to 85°C, a package of 11.5 × 13 × 1.2 mm, labels the capacities in Gb, and prints the model without the hyphen (EMMC064GYCW6T). The differences are tracked as N57.

Provenance

Datasheet figures come from the channel-supplied V2.0 file named in the source note; the manufacturer page differences come from the hiksemitech.com product page linked under “Manufacturer datasheet”. We do not host the PDF.
