Consider the [https://www.espressif.com/en/products/socs/esp32-c6 ESP32-C6] family of SoCs ( | Consider the [https://www.espressif.com/en/products/socs/esp32-c6 ESP32-C6] family of SoCs ([https://www.espressif.com/sites/default/files/documentation/esp32-c6_datasheet_en.pdf datasheet]). Each includes a unicore RISC-V running at up to 160 MHz. They are available in QFN40 and QFN32 SMD packaging. The QFN40 package (the true ESP32-C6) has no onboard flash. The ESP32-C6FH<i>x</i> and ESP32-C6FN<i>x</i> in QFN32 packaging sport <i>x</i> MB of flash, supporting High and Normal temperatures, respectively. SoCs consist of the CPU, RAM, EEPROM—all of the ICs necessary for the ESP32-C6 feature set. The F[HN]x SoCs lack GPIO10, GPIO11, GPIO14, SPICS0, SPIQ, SPIWP, VDD_SPI, and SPIHD, but gain SDIO_CLK and SDIO_CMD, for 30 vs 24 exposed pins. | ||
