Espressif’s New Excessive-Efficiency RISC-V ESP32-P4 SoC Packs in Tons of IO and Safety Options

Espressif has added a brand new system-on-chip (SoC) to the ESP32 household. The RISC V-based ESP32-P4 has three cores, 50 programmable GPIO, and a whole set of security measures. However, curiously, the chip is lacking one characteristic synonymous with “Espressif SoC:” an RF radio!

Whereas there are three CPU cores, Espressif configured them as a “big-little” structure with a high-performance (dual-core) and low-power (single-core) system. The intent is to maintain the high-performance cores powered down when not wanted.

ESP32-P4’s high-performance CPU is a dual-core RISC-V CPU working as much as 400 MHz. It has 768 kilobytes of on-chip SRAM. However, when you add an exterior PSRAM, the on-chip RAM turns into an area cache. There are additionally eight kilobytes of zero-wait tightly coupled reminiscence (TCM) for low latency buffer entry.

The low-power system is a single RISC-V core working as much as 40 MHz with devoted SRAM, ROM, and peripherals. It additionally homes the SoC’s energy administration unit (PMU). Its peripherals embody low-speed serial interfaces, a contact interface, and a temperature sensor.

Espressif touts the ESP32-P4 as having best-in-class safety. The options embody safe boot, flash encryption, true-random quantity generator, digital signature administration, entry permissions, and privileged separation.

There are 50 programmable GPIOs, essentially the most Espressif’s SoCs have ever supplied. Peripherals for the high-performance CPU embody MIPI (Digital camera and Show) interfaces, {hardware} accelerators for h264 and JPEG, USB, Ethernet, and lots of others.

For person interfaces, ESP32-P4 contains CSI and DSI interfaces, capacitive contact, and speech recognition options. For graphical shows, there’s a hardware-based Pixel Processing Accelerator.

One other first for the ESP32 household is that the ESP32-P4 doesn’t have an RF radio — of any variety! There isn’t any built-in Wi-Fi, Bluetooth, or different 2.4 GHz know-how! As a substitute, Espressif says the ESP32-P4 can join to a different ESP32 member of the family with ESP-Hosted, ESP-AT, or different third-party options. Alternatively, wired ethernet is supported.

Total, the ESP32-P4 targets edge computing purposes that want high-performance processing, superior human-machine interface, and powerful safety. Presently, ESP32-P4 particulars are restricted to this press launch. However we positively count on to listen to extra about this new entry to the ESP32 household quickly.
