Operating Voltage
L = 1.65V to 2.0VH = 2.3V to 3.6VU = 1.65V to 3.6VW = Erase/Program voltage range is 2.3V-3.6VRead and Other operations voltage range is 1.65V-3.6V.
Blank = DefaultS = Typ. Page program time reduce to 0.6msD = 01H command with only 1byte data and 31H command is valid
Note: Part number description table describes usual part-numbering system for more chips, therefore this table can contain information, that might not be valid for the actually selected chip. The information here are provided on the best-effort basis and might be either inaccurate or incoplete. Therefore always check the latest datasheet of the chip for part number description detail. If you find some inaccuracy, let us please know.
