They form the ESP32 family of microcontrollers. Since the release of the original ESP32, a number of variants have been introduced and announced. Wake up from GPIO interrupt, timer, ADC measurements, capacitive touch sensor interrupt.Cryptographic hardware acceleration: AES, SHA-2, RSA, elliptic curve cryptography (ECC), random number generator (RNG).1024-bit OTP, up to 768-bit for customers. IEEE 802.11 standard security features all supported, including WPA, WPA2, WPA3 (depending on version) and WLAN Authentication and Privacy Infrastructure (WAPI).Pulse counter (capable of full quadrature decoding).Infrared remote controller (TX/RX, up to 8 channels).Ethernet MAC interface with dedicated DMA and planned IEEE 1588 Precision Time Protocol support.SD/ SDIO/ CE-ATA/ MMC/ eMMC host controller.10 × touch sensors ( capacitive sensing GPIOs).Bluetooth: v4.2 BR/EDR and BLE (shares the radio with Wi-Fi).CPU: Xtensa dual-core (or single-core) 32-bit LX6 microprocessor, operating at 160 or 240 MHz and performing at up to 600 DMIPS.Features of the ESP32 include the following:
