2. ELECTRICAL CHARACTERISTICS Absolute maximum ratings Min Max Unit Storage temperature -40 85 °C Operating temperature -40 85 °C Supply voltage -0,3 3,6 V Terminal voltages -0,4 Vdd + 0,4 V Output current from PIOs 35 mA The module should not continuously run under these conditions. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability and cause permanent damage to the device. Recommended operating conditions Table 2: Absolute maximum ratings Min Max Unit Operating temperature -40 85 °C Supply voltage 3,1 (1)(2) 3.6 V Terminal voltages 0 Vdd V Table 3: Recommended operating conditions 1) <strong>WT11</strong> operates as low as 2,7 V supply voltage. However, to safely meet the USB specification for minimum voltage for USB data lines, minimum of 3,1 V supply is required. 2) The supply voltage has an effect on the output power of <strong>WT11</strong>. See figure 4.
