ESP32-S3 是一款集成 2.4 GHz Wi-Fi 和 Bluetooth 5 (LE) 的 MCU 芯片，支持远距离模式 (Long Range)。ESP32-S3 搭载 Xtensa® 32 位 LX7 双核处理器，主频高达 240 MHz，内置 512 KB SRAM (TCM)，具有 45 个可编程 GPIO 管脚和丰富的通信接口。ESP32-S3 支持更大容量的高速 Octal SPI flash 和片外 RAM，支持用户配置数据缓存与指令缓存。

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. Developers can take advantage of these vector instructions through ESP-DSP and ESP-NN libraries to optimize their applications. ESP-WHO and ESP-Skainet SDKs will also support this acceleration.

支持 AI 加速
ESP32-S3 MCU 增加了用于加速神经网络计算和信号处理等工作的向量指令 (vector instructions)。AI 开发者们通过 ESP-DSP 和 ESP-NN 库使用这些向量指令，可以实现高性能的图像识别、语音唤醒和识别等应用。ESP-WHO 和 ESP-Skainet 也将支持此功能。

Security
ESP32-S3 provides all the necessary security requirements for building securely connected devices, without requiring any external components. It supports AES-XTS-based flash encryption, RSA-based secure boot, digital signature and HMAC. ESP32-S3 also has a “World Controller” peripheral that provides two fully-isolated execution environments, which enables the implementation of a trusted-execution environment or a privilege-separation scheme.

完善的安全机制
ESP32-S3 为物联网设备提供了完善的安全机制和保护措施，防止各类恶意攻击和威胁。它支持基于 AES-XTS 算法的 flash 加密、基于 RSA 算法的安全启动、数字签名和 HMAC。ESP32-S3 还新增了一个“世界控制器 (World Controller)”模块，提供了两个互不干扰的执行环境，实现可信执行环境或权限分离机制。

Wi-Fi + Bluetooth 5 (LE)
ESP32-S3 supports a 2.4 GHz Wi-Fi (802.11 b/g/n) 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 Bluetooth LE have superior RF performance that is maintained even at high temperatures.

Wi-Fi + Bluetooth 5 (LE)
ESP32-S3 集成 2.4 GHz Wi-Fi (802.11 b/g/n)，支持 40 MHz 带宽；其低功耗蓝牙子系统支持 Bluetooth 5 (LE) 和 Bluetooth Mesh，可通过 Coded PHY 与广播扩展实现远距离通信。它还支持 2 Mbps PHY，用于提高传输速度和数据吞吐量。ESP32-S3 的 Wi-Fi 和 Bluetooth LE 射频性能优越，在高温下也能稳定工作。

Rich Set of IO Peripherals
ESP32-S3 has 45 programmable GPIOs, SPI, I2S, I2C, PWM, RMT, ADC, DAC and UART, SD/MMC host and TWAITM. In total, 14 GPIOs can be configured as capacitive touch input for HMI applications. Apart from all these peripherals, however, ESP32-S3 is also equipped with an ultra-low-power (ULP) core that supports multiple low-power modes in a variety of such use-cases.
