This device has two software write-protect features for the lower half of the array, as well as an external pin that can be used to write-protect the entire array. This allows the system designer to protect none, half or all of the array, depending on the application. The device is organized as one block of 256 x 8-bit memory with a two-wire serial interface. Its low-voltage design permits operation down to 1.7V, with standby and active currents of only 100 nA and 1 mA, respectively. The 34XX02 also has a page write capability for up to 16 bytes of data. Note 1: 34XX02 is used in this document as a generic part number for the 34AA02/34LC02 devices.
