The AT17C/LV020 device is implemented using two 1-Mb Configurator EEPROMs in a
multi-chip module. The A2 pin of the first internal 1Mb is set to Low by the internal pull-
down circuitry. An external 4.7 k ? pull-up must be connected to the A2 pin of the second
internal 1Mb in order to program the second device. To work with the AT17C/LV020
devices, A2 should always have a pull up on the target system. The CPS software will
implement the correct A2 value to program both internal devices. In fact, to program an
AT17C/LV020 is just like programming two 1-Mb Configurator EEPROMs in casacade
configuration.
