The chip has a built-in 400 KB SRAM，384 KB ROM，8KB RTC SRAM.Also, the chip support
external Flash while it built-in 4Mbit Flash. ESP32-C3 chip supports a variety of low-power
consumption working states, which can meet the power consumption requirements of various
application scenarios. The chip's unique features such as fine clock gating function, dynamic
voltage clock frequency adjustment function, and RF output power adjustable function can
achieve the best balance between communication distance, communication speed and power
consumption.
ESP-C3-12F provides a wealth of peripheral interfaces, including UART，PWM，SPI，I2S，
I2C，ADC，temperature sensor and there are 15 GPIOs.
ESP-C3-12F has a variety of unique hardware safety mechanisms. The hardware encryption
accelerator supports AES、SHA and RSA algorithm. Among them, RNG, HMAC and Digital
Signature modules provide more security features. Other security features include flash
encryption and se-cure boot signature verification, etc. The perfect security mechanism enables
the chip to be perfectly applied to various encryption products.
ESP-C3-12F module supports low-power Bluetooth：Bluetooth5 and Bluetooth mesh. Bluetooth
rate support: 125Kbps, 500Kbps, 1Mbps, 2Mbps. Support broadcast extension,
multi-broadcasting, channel selection.
