6 / 20 page MIC284 Micrel MIC284 6 September 29, 2000 FUNCTIONAL DESCRIPTION Pin Descriptions VDD: Power supply input. See electrical specifications. 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 some- where in the system is necessary on this line. This line is shared by all devices on the bus. A0: This inputs sets the least significant bit of the MIC284’s 7-bit slave address. The six most-significant bits are fixed and are determined by the part number ordered. (See order- ing 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 MIC284’s address and the address specified in the serial bit stream must be made to initiate communication. A0 should be tied directly to VDD or ground.

MIC284 Slave Address Settings /INT: Temperature events are indicated to external circuitry via this output. Operation of the /INT output is controlled by the MODE and IM bits in the MIC284’s configuration register. See "Comparator and Interrupt Modes" below. This output is open-drain and may be wire-OR’ed with other open-drain signals. Most systems will require a pull-up resistor or current source on this pin.
