... ID and parametric data in different portions of the E ranging from as little as one page to as much as 1/2 of the total array. The X25097 also features a WP pin that can be used for hardwire protection of the part, disabling all write attempts, as well as a Write Enable Latch that must be set before a write operation can be initiated. The X25097 utilizes Xicor’ ...

... SO pin change after the falling edge of the clock input. Chip Select (CS) When CS is HIGH, the X25097 is deselected and the SO output pin is at high impedance and unless an internal write operation is underway, the X25097 will be in the standby power mode. CS LOW enables the X25097, placing it in the active power mode ...

... LOW and remain LOW for the duration of the operation. The host may continue to write bytes of data to the X25097. The only restriction is the 16 bytes must reside on the same page. If the address counter reaches the end of the page and the clock continues, the counter will “ ...

... READ: Read operation followed by address *Instructions are shown with MSB in leftmost position. Instructions are transferred MSB first. Operational Notes The X25097 powers up in the following state: • The device is in the low power, standby state. • A HIGH to LOW transition required to enter an active state and receive an instruction. • ...
