The core processor of the module ESP-12H is a highly integrated low-power Wi-Fi system-on-chip(SoC), designed for Designed for various applications such as Internet of Things (IoT), mobile devices, wearable electronic devices, and smart homes.  ESP-12H has industry-leading low-power performance and RF performance, supports IEEE802.11b/g/n protocol, integrates Wi-Fi MAC, Wi-Fi RF and baseband, RF switch, RF Balun, power amplifier, low noise Amplifier etc.

The ESP-12H chip is equipped with an Xtensa 32-bit LX7 single-core processor with a working frequency of up to 240MHz. The chip supports secondary development without using other microcontrollers or processors. The chip has built-in 2 MB SRAM and 128 KBROM. ESP-12H 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 rate and power consumption.

ESP-12H provides a wealth of peripheral interfaces, including SPI, I2S, UART, I2C, LED PWM interface, ADC, touch sensor, temperature sensor and up to 22 GPIOs. It also includes a full-speed USB On-The-Go (OTG) interface that can support the use of USB communication. ESP32-S2F has a variety of unique hardware security mechanisms. The hardware encryption accelerator supports AES, SHA and RSA algorithms. Among them, RNG, HMAC and digital signature (Digital Signature) modules provide more security features. Other security features include flash encryption and secure boot (se-cure boot) signature verification. The perfect security mechanism enables the chip to be perfectly applied to various encryption products.
