Instead, the ESP32-P4 can communicate with other devices in the ESP32 family using ESP-Hosted, ESP-AT, or a third-party solution, as claimed by Espressif. Wi-Fi, Bluetooth, and other 2.4 GHz wireless technologies are not included.

The ESP32-P4 is the first member of the ESP32 series without a radio frequency (RF) transceiver of any type. One can use a Pixel Processing Accelerator, which is a piece of hardware, to speed up the processing of graphical displays. User interface options on the ESP32-P4 include capacitive touch, speech recognition, and CSI and DSI interfaces. MIPI (Camera and Display) ports, hardware accelerators for h264 and JPEG, USB, Ethernet, and many more are among the various peripherals available for high-performance CPUs. The 50 general-purpose I/O pins are the most ever included in an Espressif system-on-chip. Secure boot, flash encryption, a genuinely random number generator, digital signature management, access rights, and privileged isolation are all part of the package. The ESP32-P4’s superior security is one of Espressif’s main selling points. It has a touch interface, a temperature sensor, and low-speed serial interfaces as its peripherals.

It’s also where the system-on-power chip’s management circuitry is located (PMU). One RISC-V core with up to 40 MHz of clock speed plus specialized SRAM, ROM, and peripherals make up the low-power system. For low latency buffer access, there are also eight kilobytes of zero-wait tightly linked memory (TCM). When paired with an external PSRAM, however, the on-chip RAM acts as a cache for the immediate area. The SRAM on the chip is 768 kilobytes in size. The ESP32-P4‘s high-performance central processing unit (CPU) is a 400 MHz dual-core RISC-V CPU. When they aren’t needed, high-performance cores should be turned off. Interestingly, though, the chip lacks the RF radio.ĭespite having three CPU cores, Espressif set them up as a “big-little” architecture with a high-performance (dual-core) and low-power (single-core) setup, respectively. The RISC V-based ESP32-P4 has three processing cores, fifty general-purpose input/output (GPIO) pins, and a full complement of security options. The ESP32 family of system-on-chips (SoCs) from Espressif now includes a new member.
