ESP32-C6 Features
=================

ESP32-C6 is Espressif's first Wi-Fi 6 SoC integrating 2.4 GHz Wi-Fi 6, Bluetooth 5.3 (LE) and the
802.15.4 protocol. ESP32-C6 achieves an industry-leading RF performance, with reliable security
features and multiple memory resources for IoT products.
It consists of a high-performance (HP) 32-bit RISC-V processor, which can be clocked up to 160 MHz,
and a low-power (LP) 32-bit RISC-V processor, which can be clocked up to 20 MHz.
It has a 320KB ROM, a 512KB SRAM, and works with external flash.

ESP32-C6 includes the following features:

- 32-bit core RISC-V microcontroller with a clock speed of up to 160 MHz
- 400 KB of internal RAM

- Random number generator (RNG)

Low-Power CPU (LP CORE)
=======================

The ESP32-C6 SoC has two RISC-V cores: the High-Performance Core (HP CORE) and the Low-Power Core (LP CORE).
The LP Core features ultra low power consumption, an interrupt controller, a debug module and a system bus
interface for memory and peripheral access.

The LP Core is in sleep mode by default. It has two application scenarios:

- Power insensitive scenario: When the High-Performance CPU (HP Core) is active, the LP Core can assist the HP CPU with some speed and efficiency-insensitive controls and computations.
- Power sensitive scenario: When the HP CPU is in the power-down state to save power, the LP Core can be woken up to handle some external wake-up events.

The LP Core support is fully integrated with :ref:`sysbuild`. The user can enable the LP Core by adding
the following configuration to the project:

.. code:: cfg

   CONFIG_ULP_COPROC_ENABLED=y

See :zephyr:code-sample-category:`lp-core` folder as code reference.
