Symbol SCK Pin Name Serial clock SI Serial data input SO Serial data output CS Chip select WP HOLD VDD VSS Write protect Hold Power supply Ground Description This pin controls the data input/output timing. The input data and addresses are latched synchronized to the rising edge of the serial clock, and the data is output synchronized to the falling ed.
inherent to a serial flash memory device, the LE25S20FD is housed in an 8-pin ultra-miniature package. All these features make this device ideally suited to storing program in applications such as portable information devices, which are required to have increasingly more compact dimensions. The LE25S20FD also has a small sector erase capability which makes the device ideal for storing parameters or data that have fewer rewrite cycles and conventional EEPROMs cannot handle due to insufficient capacity.
Features
