ESP SoCs

Common Specifications

• Two or one CPU core(s) with adjustable clock frequency, ranging from 80 MHz to 240 MHz

• +19.5 dBm output power ensures a good physical range

• Classic Bluetooth for legacy connections, also supporting L2CAP, SDP, GAP, SMP, AVDTP, AVCTP, A2DP (SNK) and AVRCP (CT)

• Support for Bluetooth Low Energy (BLE) profiles including L2CAP, GAP, GATT, SMP, and GATT-based profiles like BluFi, SPP-like, etc

• Bluetooth Low Energy (BLE) connects to smart phones, broadcasting low-energy beacons for easy detection

• Sleep current is less than 5 μA, making it suitable for battery-powered and wearable-electronics applications

• Peripherals include capacitive touch sensors, Hall sensor, low-noise sense amplifiers, SD card interface, Ethernet, high-speed SPI, UART, I2S and I2C
