ESP32-S3 is an MCU chip that integrates 2.4 GHz Wi-Fi and Bluetooth 5 (LE) and supports Long Range. The ESP32-S3 is powered by an Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240 MHz, built-in 512 KB SRAM (TCM), 45 programmable GPIO pins and communication interfaces. ESP32-S3 supports larger-capacity high-speed Octal SPI flash and off-chip RAM, and supports -configured data cache and instruction cache. Supports Wi-Fi + Bluetooth 5 (LE) wireless connectivity: ESP32-S3 integrates 2.4 GHz Wi-Fi (802.11 b/g) supporting 40 MHz bandwidth; Bluetooth low energy subsystem supports Bluetooth 5 (LE) and Bluetooth Mesh for long-distance communication via Coded PHY and broadcast extensions. It also supports 2 Mbps PHY for increased transfer speed and data throughput. The ESP32-S3 has superior Wi-Fi and Bluetooth LE RF performance and works stably even at high temperatures. Support for AI acceleration: The ESP32-S3 MCU adds vector instructions for accelerating tasks such as neural network computation and signal processing. AI developers can use these vector instructions through the ESP-DSP and ESP-NN libraries to implement high-performance recognition, voice , and recognition applications. IO interfaces: ESP32-S3 has 45 programmable GPIOs and common peripheral interfaces such as SPI, I2S, I2C, PWM, , , UART, SD/ controller and TWAITM controller. Fourteen of these GPIOs can be configured as capacitive touch inputs for HMI interaction. In addition, ESP32-S3 is equipped with an ultra-low power co-processor (ULP), which supports a of low-power modes and is widely applicable to low-power application scenarios. Perfect security mechanism: ESP32-S3 provides perfect security mechanism and protection measures for IoT devices to prevent malicious attacks and threats. It supports flash encryption based on -XTS algorithm, based on algorithm, digital signature and HMAC. ESP32-S3 also adds a "World Controller" module, which provides two non-interfering execution environments to implement a trusted execution environment or a separation mechanism.
