8585B−SEEPR−8/10
2. Pin Descriptions
SERIAL CLOCK (SCL): The SCL input is used to positive edge clock data into each device and
negative edge clock data out of each device.
SERIAL DATA (SDA): 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.
Device Addresses (A2, A1, A0): The A2, A1, and A0 pins are device address inputs that are hardwired (directly
to GND or to V
CC
) for compatibility with two-wire devices. If these pins are left
floating, the A2, A1, and A0 pins will be internally pulled to GND. However,
Atmel
®
recommends always connecting the address pins to a known state by
direct connection to ground or V
CC.
Temperature Alert Output (
EVENT
): The
EVENT
Pin outputs a signal when the temperature goes beyond the user-
programmed temperature limit. The
EVENT
Pin is an open-drain output and can
be programmed as an interrupt, critical alarm or comparator mode.
