Espressif introduces the ESP32-P4, a high-performance microcontroller unit (MCU) system-on-chip (SoC) that marks a significant departure from the company's previous models.

It is available from distributor Ineltek.

Notably absent are the traditional Wi-Fi and Bluetooth capabilities, highlighting its unique role within Espressif's product line.

Equipped with a dual-core RISC-V CPU, the ESP32-P4 is tailored to meet the demanding requirements of advanced embedded systems and Internet of Things (IoT) devices.

This SoC excels in processing complex image and voice data, offering robust performance that enhances smart applications and connectivity options.

The RISC-V CPU operates at up to 400 MHz, and is designed to deliver efficient and robust performance for a variety of embedded applications.

This microcontroller unit (MCU) System-on-Chip (SoC) offers a balance of power and flexibility that is essential for complex IoT devices and advanced embedded systems.

The SoC comes with 32 KB of SRAM, which is used for high-speed data storage and access during processing tasks.

Additionally, it includes 128 KB of high-performance ROM and 16 KB of low-power ROM, providing ample space for firmware and application-specific code, essential for reliable and efficient operation.

In lieu of Espressif's traditional fare of wireless interfaces such as Wi-Fi or Bluetooth, the ESP32-P4 offers an extensive array of wired connectivity options.

These include multiple SPI, I2C, and UART interfaces, along with ADC and DAC channels. Such connectivity features make the ESP32-P4 highly adaptable to various industrial and consumer application needs, allowing for significant flexibility in system design.

The ESP32-P4 incorporates several advanced security features, which are crucial for applications where data integrity and confidentiality are a priority. It supports hardware-based cryptographic acceleration, secure boot, and flash encryption.

These security measures ensure that the device can operate securely in environments that require robust protection against external threats.

The chip supports a range of peripherals that enhance its usability in complex embedded systems. These include timers, PWM channels, and sensor interfaces, all of which are integral for developing interactive and responsive devices.

Designed with power efficiency in mind, the ESP32-P4 includes features that minimise power consumption during operation, making it suitable for battery-operated devices where long operational life is crucial.

The combination of these core features makes the ESP32-P4 a powerful choice for developers looking to leverage a high-performance MCU for innovative and secure applications across various sectors. Its capabilities cater to a broad spectrum of applications, enhancing both the functionality and reliability of embedded systems.
