TPIC5203 Datasheet Afterinitial device powerup, or after return from deep powerdown mode (see Bus Operations), the LH28F008SA functions as a read-only memory. Manipu- lation of external memory-control pins allow array read, standby and output disable operations. Both Status Register and intelligent identifiers can also be accessed through the Command User Interface whenVpp=VPPL. TPIC5203 Price Bus Issues At present, a maximum of 30 active sensors can coexist on the same bus, each with a different address. Address o is reserved for bus current calibration in software. This feature allows for fail-safe detection of signal current and eliminates detection problems caused by low signal current (Is), the opera- tion of sensors at various ambient tempera- tures, lot-to-lot variation of quiescent current. and the addition and replacement of sensors to the bus while in the field. Address 31 is designed to be inactive to allow for further address expansion of the bus (t0 62 maxi- mum addresses). In order to repeat the address cycle, the bus must be reset as shown in Figure l by bringing the supply voltage to below VRST. Sensors have been designed not to 'wrap-around'.
