RT9166-18PX Datasheet

In some situations the bus master may not know whether the DS18S20s on the bus are parasite powered or powered by external supplies. The master needs this information to determine if the strong bus pullup should be used during temperature conversions. To get this information, the master can issue a Skip ROM [CCh] command followed by a Read Power Supply [B4h] command followed by a "read time slot". During the read time slot, parasite powered DS18S20s will pull the bus low, and externally powered DS18S20s will let the bus remain high. If the bus is pulled low, the master knows that it must supply the strong pullup on the l-wire bus during temperature conversions.

Sensitivity Adjust. The detector sensitivity to smoke is set inter- nally by a voltage divider connected between VDD and Vss. The sensitivity can be externally adjusted to the individual characteristics of the ionization chamber by connecting a resistor between pin 13 and VDD, or between pin 13 and Vss.

any given device. If both byte enables are toggled together this value is 10 ns. tHZOE, tHZCE, tHZBE, arid tHZWE trarisitions are measured when the outputs enter a high impedance state. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = VIL. All signals must be ACTIVE to initiate a write and any of these sig nals can terminate a write by going INACTIVE. The data input set-up and hold timing should be referenced to the edge of the signal that terminates the write.
