FUNCTIONAL DESCRIPTION This chapter describes the ESP32-D0WDQ6-V3 various modules and functions. 3.1. CPU AND MEMORY ESP32-D0WDQ6-V3 contains two low-power Xtensa ® 32-bit LX6 MCU. On-chip memory comprising: ⚫448-KB of ROM, and the program starts for the kernel function calls ⚫For a 520 KB instruction and data storage chip SRAM (including flash memory 8 KB RTC) ⚫RTC flash memory of 8 KB SRAM, when the RTC can be started in Deep-sleep mode, and for storing data accessed by the main CPU ⚫RTC slow memory, of 8 KB SRAM, can be accessed by the coprocessor in Deep- sleep mode ⚫Of 1 kbit of eFuse, which is a 256 bit system-specific (MAC address and a chip set); the remaining 768 bit reserved for user program, these Flash program include encryption and chip ID 3.2. STORAGE DESCRIPTION 3.2.1. External Flash and SRAM ESP32 support multiple external QSPI flash and static random access memory (SRAM), having a hardware-based AES encryption to protect the user programs and data. ⚫ESP32 access external QSPI Flash and SRAM by caching. Up to 16 MB external Flash code space is mapped into the CPU, supports 8-bit, 16-bit and 32-bit access, and can execute code. ⚫Up to 8 MB external Flash and SRAM mapped to the CPU data space, support for 8-bit, 16-bit and 32-bit access. Flash supports only read operations, SRAM supports read and write operations. ESP32-PICO-D4 4 MB of integrated SPI Flash, the code can be mapped into CPU space, support for 8-bit, 16-bit and 32-bit access, and can execute code. Pin GPIO6 ESP32 of, GPIO7, GPIO8, GPIO9, GPIO10 and GPIO11 for connecting module integrated SPI Flash, not recommended for other functions. 3.3. CRYSTAL •ESP32-D0WDQ6-V3 40 MHz crystal oscillator. 3.4. RTC MANAGEMENT AND LOW POWER CONSUMPTION ESP32 uses advanced power management techniques may be switched between different power saving modes. (See Table 5). •Power saving mode - Active Mode: RF chip is operating. Chip may receive and transmit a sounding signal. - Modem-sleep mode: CPU can run, the clock may be configured. Wi-Fi / Bluetooth baseband and RF - Light-sleep mode: CPU suspended. RTC and memory and peripherals ULP coprocessor operation. Any wake-up event (MAC, host, RTC timer or external interrupt) will wake up the chip. - Deep-sleep mode: only the RTC memory and peripherals in a working state. Wi- Fi and Bluetooth connectivity data stored in the RTC. ULP coprocessor can work. - Hibernation Mode: 8 MHz oscillator and a built-in coprocessor ULP are disabled. RTC memory to restore the power supply is cut off. Only one RTC clock timer located on the slow clock and some RTC GPIO at work. RTC RTC clock or timer can wake up from the GPIO Hibernation mode. •Deep-sleep mode - related sleep mode: power save mode switching between Active, Modem-sleep, Light-sleep mode. CPU, Wi-Fi, Bluetooth, and radio preset time interval to be awakened, to ensure connection Wi-Fi / Bluetooth. - Ultra Low-power sensor monitoring methods: the main system is Deep-sleep mode, ULP coprocessor is periodically opened or closed to measure sensor data. The sensor measures data, ULP coprocessor decide whether to wake up the main system. Functions in different power consumption modes: TABLE 5 7 4. ELECTRICAL CHARACTERISTICS 4.1. LIMIT PARAMETERS Table 8: Limiting values V IO to the power supply pad, Refer ESP32 Technical Specification Appendix IO_MUX, as SD_CLK of Power supply for VDD_SDIO. Press and hold the side power button for two seconds to start the device.Press and hold for more than 6 seconds to turn off the device. Switch to the photo mode through the Home screen, and the avatar that can be obtained through the camera is displayed on the tft screen.The USB cable must be connected when working, and the lithium battery is used for short-term storage to prevent power failure.
