Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel.

Four bits are fixed (0101), three bits (xyz) are variable, and the least-significant bit is the read/write bit. 2 Modules with I C capability monitor up to five analog 8 bit Address parameters and six status bits identified below in Tables 1and 2 respectively. 0101 xyz* R/W 2 Table 3: Address structure Modules with I C Option Features: Address Selection: The three bits (xyz) of the address are set with a single external resistor from the ADD (pin10) to LOGIC_GND (pin 13). The 8 possible addresses are shown in Table 4 with the respective Table 1: Internal register memory map resistance values. Table 2: Digital signals 2 Table 4: I C Addressing Note: Bit 0=LSB, Bit 7=MSB 2 I C Command Structure: 2 The I C is a 2-wire interface supporting multiple devices and masters on a single bus. The connected devices can only pull the bus wires low and they never drive the bus high. The bus wires should be externally connected to a positive supply voltage via a pull-up resistor. When the bus is idle, both DAT 2 and CLK are high. The max sink current supported on the I C bus is 3.5mA. 2 Each device on the I C bus is recognized by a unique address stored in that device. Devices can be classified as masters or slaves when performing data transfers. A master is a device which initiates a data transfer on the bus and generates clock signals to permit that transfer. At the same time, any device addressed is considered slave. The PIM400 always acts as a slave. 2 In PIM400 module, I C interface is used for reporting critical parameters like input voltage, output current, holdup capacitor voltage and temperature data.
