All specifications are over process and voltage, unless otherwise indicated. 4.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VBAT and VIO Pins: 37, 39, 44 –0.5 3.8 V VIO – VBAT (differential) Pins: 10, 54 0.0 V Digital inputs –0.5 VIO + 0.5 V RF pins –0.5 2.1 V Analog pins, XTAL Pins: 22, 23, 51, 52 –0.5 2.1 V Operating temperature, TA –40 85 °C Storage temperature, Tstg –55 125 °C (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 4.2 ESD Ratings VALUE UNIT VESD Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V Charged device model (CDM), per JEDEC specification JESD22-C101(2) ±500 4.3 Power-On Hours NOTE This information is provided solely for your convenience and does not extend or modify the warranty provided under TI's standard terms and conditions for TI semiconductor products. (1) The TX duty cycle (power amplifier ON time) is assumed to be 10% of the device POH. Of the remaining 90% of the time, the device can be in any other state. CONDITIONS POH TA up to 85°C (1) 87,600 (1) Operating temperature is limited by crystal frequency variation. (2) When operating at an ambient temperature of over 75°C, the transmit duty cycle must remain below 50% to avoid the auto-protect feature of the power amplifier. If the auto-protect feature triggers, the device takes a maximum of 60 seconds to restart the transmission. (3) To ensure WLAN performance, ripple on the 2.1- to 3.3-V supply must be less than ±300 mV. (4) The minimum voltage specified includes the ripple on the supply voltage and all other transient dips. The brownout condition is also 2.1 V, and care must be taken when operating at the minimum specified voltage. (5) To ensure WLAN performance, ripple on the 1.85-V supply must be less than 2% (±40 mV). (6) TI recommends keeping VBAT above 1.85 V. For lower voltages, use a boost converter. 4.4 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) (2) MIN TYP MAX UNIT VBAT, VIO (shorted to VBAT) Pins: 10, 37, 39, 44, 54 Direct battery connection(3) 2.1(4) 3.3 3.6 V Preregulated 1.85 V(5)(6) Ambient thermal slew –20 20 °C/minute |
