2. Electrical Characteristics 2.1. Absolute Maximum Ratings Over operating free-air temperature range Supply Voltage Range Doc No: WG7310-00-HDG-R03 Characteristics Value Unit VBAT -0.5 to 5.5 V VIO -0.5 to 2.1 V Input Voltage to Analog Pins -0.5 to 2.1 V Input Voltage to all Other Pins -0.5 to VIO + 0.5V V Operating Ambient Temperature Range -20 to 70 °C Storage Temperature Range -45 to 85 °C 2.2. Recommended Operating Conditions The WG7310 requires two supplies: VBAT and VIO. Power Supply Voltage Min. Typ. Max. VBAT 2.7V 3.3V 4.8V VIO 1.62V 1.8V 1.92V 2.3. External Slow Clock Input (SLEEP_CLK) The external slow clock input SLEEP_CLK must be present at all times. The slow clock is used to maintain timers that synchronize the device to the access point (AP) beacons. Table 1. External Slow Clock Input Requirements Characteristics Condition Min. Typ. Max.
