This device has two software writeprotect 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 2-wire serial interface. Lowvoltage 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. The 34XX02 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, MSOP and TDFN packages. The 34XX02 is also available in the 6-lead, SOT-23 package.
