Esp32-S3 is an MCU chip that integrates 2.4 GHz Wi-Fi and Bluetooth 5 (LE) and supports Long Range mode. The ESP32-S3 runs on an Xtensa 32-bit LX7 dual-core processor with a high frequency of 240 MHz 512 KB built-in SRAM (TCM) 45 programmable GPIO pins and a rich communication interface. Esp32-s3 supports larger capacity of high-speed Octal SPI flash and off-chip RAM and supports user-configured data caching and instruction caching. Wi-Fi + Bluetooth 5 (LE) Wireless Connectivity: ESP32-S3 supports a 2.4 GHz Wi-Fi (802.11 b/g) with 40 MHz of bandwidth support. The Bluetooth Low Energy subsystem supports long range through Coded PHY and advertisement extension. It also supports higher transmission speed and data throughput with 2 Mbps PHY. Both Wi-Fi and have superior RF performance that is maintained even at high temperatures. AI Acceleration Support: ESP32-S3 has additional support for vector instructions in the MCU which provides acceleration for neural network computing and signal processing workloads. The software libraries for the above-mentioned optimized functions will become available very soon in the form of updates to ESP-DSP and ESP-NN. Rich IO interfaces: ESP32-S3 has 45 programmable GPIOs and common peripheral interfaces such as SPI I2S I2C PWM ADC UART SD/MMC host controller and TWAITM controller. Fourteen of the GPIOs can be configured as capacitive touch inputs for HMI interaction. In addition ESP32-S3 is equipped with an ultra-low power coprocessor (ULP) and supports multiple low-power modes making it widely applicable to low-power application scenarios. Security mechanism: ESP32-S3 provides comprehensive security mechanism and protection measures for iot devices to prevent all kinds of malicious attacks and threats. It supports Flash encryption based on -XTS algorithm secure startup based on RSA algorithm digital signature and HMAC. Esp32-s3 also includes a new "World Controller" module which provides two non-interfering execution environments to implement a trusted execution environment or permission separation mechanism.
