Introducing Espressif ESP32-P4

The ESP32-P4 is powered by a dual-core RISC-V CPU that can run up to 400MHz. It supports single-precision FPU and AI extensions, providing ample computational resources. The SoC also integrates an LP-Core running up to 40MHz, ideal for ultra-low-power applications that may occasionally require high computing power.

CPU and Memory: A Closer Look

Dual-Core RISC-V CPU

The ESP32-P4 is powered by a dual-core RISC-V CPU that can run up to 400MHz. This CPU architecture is designed for high-performance computing and supports single-precision Floating Point Unit (FPU) and AI extensions.

LP-Core for Ultra-Low-Power Applications

The SoC also integrates an LP-Core that can run up to 40MHz. This is particularly critical for ultra-low-power applications that may occasionally require high computing power. In such scenarios, the high-performance (HP) cores can be kept in a low-power state to save energy.

Memory Subsystem

  • On-Chip SRAM: 768KB, accessible as cache when external PSRAM is available.

  • Zero-Wait TCM RAM: 8KB for fast data buffers or time-critical sections of code.

  • External PSRAM and Flash Support: Ensures that memory-access latency and available size of memory are not limited.

Human-Machine Interface: Beyond the Basics


The SoC supports MIPI-CSI with integrated Image Signal Processor (ISP) and MIPI-DSI for high-resolution cameras and display interfaces.

Capacitive Touch and Speech Recognition

These features make the ESP32-P4 an ideal choice for any Human-Machine Interface (HMI) based application.

Hardware Accelerators for Media Encoding

The SoC integrates hardware accelerators for various media-encoding protocols, as well as compression protocols for image processing and video streaming, including H.264 encoding support.

Security: More Than Just a Buzzword

Secure Boot and Flash Encryption

The ESP32-P4 features Secure Boot and Flash Encryption, ensuring that the device boots only authenticated software and keeps stored data secure.

Cryptographic Accelerators and TRNG

Cryptographic accelerators and a True Random Number Generator (TRNG) provide additional layers of security.

Digital Signature and Key Management

A dedicated Key Management Unit and Digital Signature Peripheral ensure that private keys are generated on the SoC itself, offering protection against software and physical attacks.
