3 of 40 july 19, 2007 idt 89hpes32h8 data sheet as shown in figure 3, the master and slave smbuses may be used in a unified or split configurati on. in the unified configuratio n, shown in figure 3(a), the master and slave smbuses are tied together and the pes32h8 acts both as a smbus master as well as a smbus slave on th is bus. this requires that the smbus master or processor that has access to pes32h8 registers supports smbus arbitration. in some systems, t his smbus master interface may be implemented using general purpose i/o pins on a pr ocessor or micro controller, and may not support smbus arbit ration. to support these systems, the pes32h8 may be configured to operate in a split configuration as shown in figure 3(b). in the split configuration, the master and slave smbuses operat e as two independent buses and thus multi-master arbitration is never required. the pes32h8 supports reading and writing of the serial eeprom on the master smbus via the slave smbus, allowing in system progr amming of the serial eeprom. figure 3 smbus interface configuration examples hot-plug interface the pes32h8 supports pci express hot-plug on each downstream port (ports 1 through 7). to reduce the number of pins required on the device, the pes32h8 utilizes an external i/o expander, such as that used on pc motherboards, connected to the smbus master interface. f ollowing reset and configuration, whenever the state of a hot-plug output needs to be modified, the pes32h8 generates an smbus transaction to the i/o expander with the new value of all of the outputs. whenever a hot-plug input changes, the i/o expander generates an interrupt which is r eceived on the ioex- pintn input pin (alternate function of gpio) of the pes32h8. in response to an i/o expander interrupt, the pes32h8 generates an smbus transac- tion to read the state of all of the hot-plug inputs from the i/o expander. general purpose input/output the pes32h8 provides 32 general purpose i/o (gpio) pins that may be individually configured as general purpose inputs, general purpose outputs, or alternate functions. some gpio pins are shared wi th other on-chip functions. these alternate functions may be enabl ed via software, smbus slave interface, or serial configuration eeprom. bit slave smbus address master smbus address 1 ssmbaddr[1] msmbaddr[1] 2 ssmbaddr[2] msmbaddr[2] 3 ssmbaddr[3] msmbaddr[3] 4 0 msmbaddr[4] 5 ssmbaddr[5] 1 61 0 71 1 table 1 master and slave smbus address assignment processor pes32h8 ssmbclk ssmbdat msmbclk msmbdat smbus master other smbus devices serial eeprom processor pes32h8 ssmbclk ssmbdat msmbclk msmbdat smbus master other smbus devices serial eeprom ... ...

17 of 40 july 19, 2007 idt 89hpes32h8 data sheet thermal considerations this section describes thermal considerations for the pes32h8 (31mm 2 fcbga900 package). the data in table 16 below contains information that is relevant to the thermal performance of the pes32h8 switch. note: it is important for the reliability of this device in any us er environment that the junction temperature not exceed the t j(max) value specified in table 16. consequently, the effectiv e junction to ambient thermal resistance ( ja ) for the worst case scenario must be maintained below the value determined by the formula: ja = (t j(max) - t a(max) )/p given that the values of t j(max) , t a(max) , and p are known, the value of desired ja becomes a known entity to the system designer. how to achieve the desired ja is left up to the board or system designer, but in general, it can be achieved by adding the effects of jc (value provided in table 16), thermal resistance of the chosen adhesive ( cs ), that of the heat sink ( sa ), amount of airflow, and properties of the circuit board (number of layers and size of the board). as a general guideline, this device will not need a heat sink if the bo ard has 10 or more layers and the board size is larger than 4"x12" and airf low in excess of 1 m/s is available. it is strongly recommended th at users perform their own thermal analysis for their own board and system design scenarios. symbol parameter value units conditions t j(max) junction temperature 125 o c maximum t a(max) ambient temperature 70 o c maximum jc thermal resistance, junction-to-case 0.2 o c/w p power dissipation of the device 6.81 watts maximum table 16 thermal specifications for pes32h8, 31x31 mm fcbga900 package
