ESP32-P4 is coming

[Andreas]

Nach den bei ESP32-C3 and ESP32-C6 are coming und ESP32-H2 is coming vorgestellten Modellen wurde im Januar 2023 der ESP32-P4 angekündigt – ebenfalls basierend auf RISC-V, siehe Espressif Reveals ESP32-P4: A High-Performance MCU with Numerous IO-Connectivity and Security Features | Espressif Systems.

Das wesentliche dabei ist:

Espressif is expanding its current portfolio to address the high-performance computation needs of IO-Rich, HMI, and AIoT applications.

About

It is powered by a dual-core RISC-V CPU with an AI instructions extension, an advanced memory subsystem, and integrated high-speed peripherals. ESP32-P4 is designed for high-performance applications that require strong security. In fact, ESP32-P4 aims to cater to the next era of embedded applications which will rely on solid support for rich Human-Machine Interfaces, efficient edge computing, and increased IO-connectivity requirements.

Weitere Details

Powered by a dual-core RISC-V CPU running up to 400MHz, ESP32-P4 also supports single-precision FPU and AI extensions, thus providing all the necessary computational resources. In addition, ESP32-P4 integrates an LP-Core which can run up to 40MHz.

The ESP32-P4 HP core system has 768KB of on-chip SRAM, which can become accessible as cache when external PSRAM is available. In addition, the ESP32-P4 HP core system has 8KB of zero-wait TCM RAM, which can be used for fast data buffers or time-critical sections of code. This high-performance memory system, along with the support for external PSRAM and Flash, ensures that the memory-access latency and the available size of memory are not limited.

ESP32-P4 has more than 50 programmable GPIOs, which is significantly more than those of any other Espressif SoC to date. ESP32-P4 supports all the commonly used peripherals, such as SPI, I2S, I2C, LED PWM, MCPWM, RMT, ADC, DAC, UART, and TWAITM. Further to this, ESP32-P4 supports USB OTG 2.0 HS, Ethernet, and SDIO Host 3.0 for high-speed connectivity.

Im Gegensatz zum ESP32-H2 hat diese Variante kein WiFi und Bluetooth.

If the application requires wireless connectivity, ESP32-P4 can easily connect, as a wireless companion chip, to any product of the ESP32-C/S/H series over SPI/SDIO/UART, by using the ESP-Hosted or ESP-AT solutions. ESP32-P4 can also function as the Host MCU for other connectivity solutions, such as ACK, AWS IoT ExpressLink, etc.
