Functional Description
Pin Descriptions
VDD: Power supply input. See electrical specications.
GND: Ground return for all MIC284 functions.
CLK: Clock input to the MIC284 from the two-wire serial bus.
The clock signal is provided by the host, and is shared by all
devices on the bus.
DATA: Serial data I/O pin that connects to the two-wire serial
bus. DATA is bi-directional and has an open-drain output driver.
An external pull-up resistor or current source somewhere in
the system is necessary on this line. This line is shared by
all devices on the bus.
A0: This inputs sets the least signicant bit of the MIC284s
7-bit slave address. The six most-signicant bits are xed and
are determined by the part number ordered. (See ordering
information table above.) Each MIC284 will only respond to
its own unique slave address, allowing up to eight MIC284s to
share a single bus. A match between the MIC284s address
and the address specied in the serial bit stream must be
made to initiate communication. A0 should be tied directly
to VDD or ground. See "Temperature Measurement and
Power On" for more information. A0 determines the slave
address as shown in Table 1:

Table 1. MIC284 Slave Address Settings
/INT: Temperature events are indicated to external ircuitry
via this output. Operation of the /INT output is controlled by
the MODE and IM bits in the MIC284s conguration register.
See "Comparator and Interrupt Modes" below. This output
is open-drain and may be wire-ORed with other open-drain
signals. Most systems will require a pull-up resistor or current
source on this pin. If the IM bit in the conguration register
is set, it prevents the /INT output from sinking current. In
I
2
C and SMBus systems, the IM bit is therefore an interrupt
