1.Complete security mechanism: ESP32S3 provides a complete security mechanism and protection measures for IoT devices to prevent various malicious attacks and threats. It supports flash encryption based on the XTS algorithm, secure boot based on the algorithm, digital signatures and HMAC. ESP32S3 also adds a 'World Controller' module, which provides two noninterfering execution environments to implement a trusted execution environment or a privilege separation mechanism 2.Rich IO interfaces: ESP32S3 has 45 programmable GPIOs and commonly used peripheral interfaces such as SPI, I2S, I2C, PWM, ADC, UART, SD/MMC host controller and TwAITM controller. 14 of the GPIOs can be configured as capacitive touch inputs for HMI interaction. In addition, ESP32S3 is equipped with an ultralow power coprocessor (ULP), which supports multiple lowpower modes and is widely applicable to various lowpower application scenarios 3.Support for AI acceleration: ESP32S3 MCU adds vector instructions for accelerating neural network calculations and signal processing. AI developers can use these vector instructions through the ESP and ESPNN libraries to achieve performance image recognition, voice wakeup and recognition applications. ESPWHO and ESPSkainet also support this feature 4.WiFi Bluetooth 5 (LE): ESP32S3 integrates 2.4 GHz WiFi (802.11 b/g) and supports 40 MHz bandwidth; its lowpower Bluetooth subsystem supports Bluetooth 5 (LE) and Bluetooth Mesh, and can achieve longdistance communication through Coded PHY and broadcast extension. It also supports 2 Mbps PHY to increase transmission speed and data throughput. ESP32S3's WiFi and Bluetooth LE radio performance are and can work stably even at temperatures
