The VCC input is a 2.7V-to-5.5V positive voltage supplied by the host.
The SCL input is used to positive edge clock data into the device and negative edge clock data
out of the device.
The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be
wire-ORed with any number of other open-drain or open-collector devices. An external pull-up
resistor should be connected between SDA and VCC. The value of this resistor and the system
capacitance loading the SDA bus will determine the rise time of SDA. This rise time will deter-
mine the maximum frequency during read operations. Low value pull-up resistors will allow
higher frequency operations while drawing higher average power supply current.
When the RST input is pulsed high, the device will output the data programmed into the 32-bit
answer-to-reset register. All password and authentication access will be reset. Following a reset,
device authentication and password verification sequences must be presented to re-establish
user access.
