Open-drain pin that carries both bidirectional serial data and parasitic power (2.5V-5.5V) to the device. Requires an external ~1 kΩ pull-up resistor to the host supply for normal operation, and a strong MOSFET pull-up during Copy-Scratchpad-to-EEPROM writes (tWR = 9 ms). |+| 2 | N.C. | unconnected | No connect.
