CPU AND MEMORY
The ESP32-D0WDQ6 is equipped with two low-power Xtensa B32-bit LX6 MCUs.
On-chip storage includes 448KB of ROM for program booting and kernel function calls.
There is also 520KB of on-chip SRAM for data and instruction storage. The RTC has 8KB of SRAM, known as RTC slow memory, which can be accessed by the co-processor during Deep-sleep mode. Additionally, there is another 8KB of SRAM in the RTC, known as RTC fast memory, which can be used for data storage during rtc startup in deep sleep mode and can be accessed by the main CPU. The eFuse has 1kbit, with 256 bits dedicated to system-specific purposes (MAC address and chip settings), and the remaining 768 bits reserved for user applications, including flash encryption and chip ID.
The ESP-WROOM-32 integrates a 4MB SPI Flash.
Onboard CP2104 stable TTL chip ensures normal communication of the serial port.
Supports automatic downloading, no need to manually switch between download and run modes.
Uses the popular TYPE-C communication interface in the market.
Supports development on systems such as cygwin, msys32 simulation environment, and Linux.
Supports ESP32.
ESP-WRoom-32 is a versatile Wi-Fi+BT+BLE MCU module with powerful functionality, wide range of applications, and can be used for low-power sensor networks and demanding tasks such as voice encoding, audio streaming, and MP3 decoding.
The core of this module is the ESP32-D0WDQ6 chip, which has expandable and adaptive features. The two CPU cores can be controlled or powered on separately. The clock frequency can be adjusted from 80 MHz to 240 MHz. Users can power off the CPU and use the low-power co-processor to continuously monitor the status changes of peripherals or whether certain analog quantities exceed the threshold.
ESP32 also integrates various peripherals, including capacitive touch sensors, Hall sensors, low-noise sensor amplifiers, SD card interfaces, Ethernet interfaces, high-speed SDIO SPI, UART, I2S, and I2C, etc.
