The 32-bit core RISC-V microcontroller features a maximum clock speed of 160 MHz. With 22 configurable GPIOs, 400 KB of internal RAM and low-power-mode support, it can facilitate many different use-cases involving connected devices. The high-temperature support makes it ideal for industrial and lighting use-cases as well. The module is supported through Espressif’s open-source ESP-IDF making it easy to develop around.
WiFi and Bluetooth LE 5.0 with long-range (LR) support help building devices with great coverage and improved usability. ESP32-C3 continues to support Bluetooth LE SIG Mesh and Espressif WiFi Mesh. Furthermore, the solid RF performance of ESP32-C3 is sustained at a higher operating temperature.
Security is now a main feature of the ESP32 line. The ESP32-C3 ensures that the availability of features, such as the RSA-3072-based secure boot and the AES-128-XTS-based flash encryption, can be used to build connected devices securely. The innovative digital signature peripheral and the HMAC peripheral provide a secure device identity for applications. Hardware acceleration support for cryptographic algorithms ensures good performance for the secure communication both in a local network and with the Cloud.
