The W25Q40EWUXIE is a 4Mbit (512KB) Serial NOR Flash Memory from Winbond operating at 1.65V to 1.95V with Standard\/Dual\/Quad SPI interface. The EW series is the ultra-low-voltage (1.8V) variant of the popular W25Q family, with clock rates up to 104 MHz. The UXIE suffix indicates USON-8 (2x3mm) package with industrial temperature range and tape & reel packing, ideal for ultra-compact 1.8V IoT and wearable designs.<\/p>\n
