During the chip's system reset (power-on reset, RTC watchdog reset and brownout 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. The strapping bits configure the device boot mode, the operating voltage of VDD_SDIO and other system initial settings. Each strapping pin is connected with its internal pull-up/pull-down during the chip reset. Consequently, if a strapping pin is unconnected or the connected external circuit is high-impendence, the internal weak pull-up/pulldown will determine the default input level of the strapping pins. To change the strapping bit values, users can apply the external pull-down/pull-up resistances, or apply the host MCU's GPIOs to control the voltage level of these pins when powering on ESP32. After reset, the strapping pins work as the normal functions pins. Refer to Table 3 for detailed boot modes'configuration by strapping pins.

The internal memory includes: • 448 kB of ROM for booting and core functions. • 520 kB (8 kB RTC FAST Memory included) of on-chip SRAM for data and instruction. • 8 kB of SRAM in RTC, which is called RTC FAST Memory and can be used for data storage; it is accessed by the main CPU during RTC Boot from the Deep-sleep mode. • 8 kB of SRAM in RTC, which is called RTC SLOW Memory and can be accessed by the co-processor during the Deep-sleep mode. • 1 kbit of eFuse, of which 256 bits are used for the system (MAC address and chip configuration) and the remaining 768 bits are reserved for customer applications, including Flash-Encryption and Chip-ID. 3.2.2 Low-Power Management With the use of advanced power management technologies, ESP32 can switch between different power modes. • Power modes – Active mode: The chip radio is powered on. The chip can receive, transmit, or listen. – Modem-sleep mode: The CPU is operational and the clock is configurable. The Wi-Fi/Bluetooth baseband and radio are disabled. – Light-sleep mode: The CPU is paused. The RTC memory and RTC peripherals, as well as the ULP co-processor are running. Any wake-up events (MAC, host, RTC timer, or external interrupts) will wake up the chip. – Deep-sleep mode: Only the RTC memory and RTC peripherals are powered on. Wi-Fi and Bluetooth connection data are stored in the RTC memory. The ULP co-processor can work. – Hibernation mode: The internal 8-MHz oscillator and ULP co-processor are disabled. The RTC recovery memory is powered down. Only one RTC timer on the slow clock and some RTC GPIOs are active.The RTC timer or the RTC GPIOs can wake up the chip from the Hibernation mode. • Sleep Patterns – Association sleep pattern: The power mode switches between the Active mode, Modem- andLightsleep Wireless-Tag Technology Co.,Limited http://www.wireless-tag.com - 10 - WT32-S1 WiFi/BT DATASHEET mode during this sleep pattern. The CPU, Wi-Fi, Bluetooth, and radio are woken up at predetermined intervals to keep Wi-Fi/BT connections alive. –ULP sensor-monitored pattern: The main CPU is in the Deep-sleep mode. The ULP co-processor takes sensor measurements and wakes up the main system, based on the data collected from sensors. Table-4 Functionalities Depending on the Power Modes Power mode Active Modem-sleep Light-sleep radio RTC memory and RTC peripherals ULP co-processor OFF ON ON PAUSE ON OFF OFF OFF OFF ON ON ON ON OFF ON ON ON ON /OFF OFF Association sleep pattern Wi-Fi/BT baseband and Hibernation ULP sensormonitored pattern OFF Sleep mode CPU Deep-sleep Table-5 Power Consumption by Power Modes Power mode Description Power consumption Modem-sleep The CPU is powered on. Max speed 240 MHz: 30 mA ~ 50 mA Normal speed 80 MHz: 20 mA ~ 25 mA Slow speed 2 MHz: 2 mA ~ 4 mA Light-sleep Deep-sleep Hibernation Power off 0.8 mA The ULP co-processor is powered on. 150 μA ULP sensor-monitored pattern 100 μA @1% duty RTC timer + RTC memory 10 μA RTC timer only CHIP_PU is set to low level, the chip is powered off 5 μA 0.1 μA Note: • In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on the CPU load and the peripherals used. • During Deep-sleep, when the ULP co-processor is powered on, peripherals such as GPIO and I2C are able to work. • When the system works in the ULP sensor-monitored pattern, the ULP co-processor works with the ULP sensor periodically; ADC works with a duty cycle of 1%, so the power consumption is 100 μA.
