ESP32-S3 is an MCU chip with integrated 2.4 GHz Wi-Fi and Bluetooth 5 (LE), supporting long range mode (Long Range). ESP32-S3 is equipped with Xtensa 32-bit LX7 dual-core processor, with a main frequency of up to 240 MHz, built-in 512 KB (TCM), 45 programmable GPI0 pins and rich communication interfaces. ESP32-S3 supports larger capacity high-speed OctalSPlflash and off-chip RAM to support user-configured data cache and instruction cache. Support AI acceleration ESP32-S3 MCU adds vector instructions for accelerating neural network calculations and signal processing. Al developers can use these vector instructions through ESP- and ESP-NN libraries to achieve high-performance image recognition, voice and recognition applications. ESP-WHO and ESP-Skainet will also support this feature. ESP32-S3 integrates 2.4 GHz Wi-Fi (802.11 b/g) supporting 40 MHz bandwidth; its low-power Bluetooth subsystem supports Bluetooth5 (LE) and Bluetooth Mesh, and can achieve long-distance communication through Coded PHY and broadcast extension. It also supports 2 Mbps PHY to increase transmission speed and data throughput. The Wi-Fi and Bluetooth LE radio performance of ESP32-S3 are excellent and can work stably even at high temperatures. ESP32-S3 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. ESP32-S3 also adds a "World Controller" module, which provides two non-interfering execution environments to implement a trusted execution environment or permission separation mechanism.
