Espressif Systems ESP32-P4 System-on-Chip (SoC)

Espressif Systems ESP32-P4 System-on-Chip (SoC) is a high-performance MCU for rich HMI, edge computing, image processing, and voice processing applications. The ESP32-P4 combines a dual-core 32-bit RISC-V processor running up to 400MHz with a 40MHz low-power RISC-V core for workloads that require high performance and energy efficiency. Integrated MIPI CSI, MIPI DSI, image signal processing, H.264 encoding, JPEG processing, and pixel acceleration support advanced camera, display, and multimedia designs.

The Espressif Systems ESP32-P4 includes 55 programmable GPIOs and high-speed interfaces for USB 2.0, Ethernet, SD/MMC, audio, motor control, and industrial communication. Dedicated security capabilities include secure boot, external memory encryption, cryptographic accelerators, digital signature peripherals, true random number generation, and secure key management. The ESP32-P4 SoC is designed for smart home systems, service robots, industrial automation, healthcare devices, retail terminals, multimedia players, video-streaming cameras, smart voice terminals, edge vision AI processors, and HMI control panels.
