Note:
1. All memory is retained in sleep mode. WUP on timer and/or interrupt.
2. All memory is retained and Xtal oscillator is kept on if no 32 kHz clock is provided.
3. Requires complete start-up sequence to resume operation.
4. All DTIM currents assume a 1 ms beacon time duration with a beacon interval of 102.4ms from the AP.
4.4 RF Transmitter General Characteristics
Unless otherwise indicated, typical conditions are: Operating Ambient Temp = 25 °C, V
VDD_IO
= V
VDD
= 1.8 V; V
VDD_PA
= 3.3V, center
frequency = 2,442 MHz, and measured in 50 Ω test equipment attached at antenna port. The output power levels are backed off to
ensure compliance into a 2:1 VSWR antenna at the worst phase angles. More details are in UG395: WFM200 Hardware Design User's
Guide.
Measurements for this specification are made using the RF_1 port. See Section 5.4.1 RF Ports.
