Wireless-Tag Technology Co., Ltd. V1.0.0 3 Pin Definitions 3.1 Pin Layout Figure 2 Pin Layout The pin descriptions are as follows. Table 1 Pin Definitions and Descriptions Pin Name Description Chip Enable pin: High level: on, enables the chip. Low level: off, the chip powers off, low current. Note: Do not leave the EN pin floating. 1 EN 2 IO1 GPIO1, ADC1_CH1, XTAL_32K_N (32.
Wireless-Tag Technology Co., Ltd. V1.0.0 GPIO9 Software can read the strapping values of these pins in “GPIO_STRAPPING” register. During the chip’s system reset(power-on-reset, RTC watchdog reset, brownout reset, analog super watchdog reset, crystal clock glitch detection reset), the latches of the strapping pins sample the voltage level as strapping bits of “0” or “1”, and hold these bits until the chip is powered down or shut down. By default, GPIO9 is connected to the internal pull-up resistor.
Wireless-Tag Technology Co., Ltd. V1.0.0 Figure 3 shows the setup and hold times for the strapping pin before and after the CHIP_EN signal goes high. Figure 3 Setup and Hold Times for the Strapping Pin Note: 1. The strapping combination of GPIO8 = 0 and GPIO9 = 0 is invalid. Copyright ©2020 Wireless-Tag Technology Co., Ltd.

Wireless-Tag Technology Co., Ltd. V1.0.0 4 Electrical Characteristics 4.1 Absolute Maximum Ratings Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
Wireless-Tag Technology Co., Ltd. V1.0.0 802.11n, HT20, MCS7, @17.5dBm 276 802.11n, HT40, MCS7, @17dBm 252 802.11b/g/n, HT20 84 802.11n, HT40 87 RX Note: 1. The current consumption measurements are taken with a 3.3 V supply at 25 °C of ambient temperature at the RF port. All transmitters’ measurements are based on a 100% duty cycle. 2. The current consumption figures in RX mode are for cases when the peripherals are disabled and the CPU is idle.

Wireless-Tag Technology Co., Ltd. V1.0.0 5.4 Peripheral Schematic This is the typical application circuit of the module connected with peripheral components (for example, power supply, antenna, reset button, JTAG interface, and UART interface). Figure 7 Application Circuit Note: Soldering the EPAD to the ground of the base board is not a must, though doing so can get optimized thermal performance. If you do want to solder it, please ensure that you apply the correct amount of soldering paste.
