This Data Retention > 200 Years device has two software write-protect features for the 8-Lead PDIP, SOIC, TSSOP, MSOP and TDFN lower half of the array, as well as an external pin that packages can be used to write-protect the entire array. This allows the system designer to protect none, half, or all 6-Lead SOT-23 Package of the array, depending on the application. The device Pb-free and RoHS Compliant is organized as one block of 256 x 8-bit memory with a Temperature Range: 2-wire serial interface. Low-voltage design permits - -20C to +85C operation down to 1.5V, with standby and active cur- rents of only 100nA and 1mA, respectively. The Device Selection Table 34VL02 also has a page write capability for up to 16 bytes of data. The 34VL02 is available in the standard VCC Max. Clock Part Number 8-pin PDIP, surface mount SOIC, TSSOP, MSOP and Range Frequency TDFN packages. The 34VL02 is also available in the (1) 34VL02 1.5-3.6 400 kHz 6-lead, SOT-23 package.
