Designed for next-generation AIoT applications, ESP32-S31 is a high-performance dual-core RISC-V SoC with comprehensive wireless connectivity, making it ideal for smart home hubs, smart speakers, edge AI devices, industrial automation, and more.
Espressif Systems (SSE: 688018) announces that its ESP32-S31 has entered mass production and is now available for purchase. Designed for next-generation AIoT applications, ESP32-S31 is a high-performance dual-core RISC-V SoC with comprehensive wireless connectivity, making it ideal for smart home hubs, smart speakers, edge AI devices, industrial automation, and more.
ESP32-S31 features a dual-core 32-bit RISC-V CPU running at up to 320 MHz, with one core supporting a 128-bit data path and SIMD instruction set for accelerated computing performance. The chip also integrates a 40 MHz low-power coprocessor, 512 KB of on-chip SRAM, support for high-speed 250 MHz DDR PSRAM expansion, and up to 60 GPIOs.
ESP32-S31 integrates Wi-Fi 6 (2.4 GHz), Bluetooth 5.4 (including LE Audio and Classic BR/EDR), IEEE 802.15.4 (Zigbee and Thread), and a Gigabit Ethernet MAC. It also supports Matter over both Wi-Fi and Thread.
To support rich human-machine interaction, ESP32-S31 provides interfaces for DVP cameras, multiple LCD display types, and up to 14 capacitive touch channels. Dedicated hardware accelerators (including a JPEG encoder/decoder and a 2D graphics accelerator) help improve multimedia performance, while dual I2S controllers enable hardware-level Bluetooth audio synchronization.
