Overview
Espressif’s ESP8266EX delivers highly integrated Wi-Fi So C solution to meet users’ continuous demands for ef cient power usage, pact design and reliable performance in the Internet of Things industry.
With the plete and self-contained Wi-Fi networking capabilities, ESP8266EX can perform either as a standalone application or as the slave to a host MCU. When ESP8266EX hosts the application, it promptly boots up from the ash. The integrated highspeed cache helps to increase the system performance and optimize the system memory. Also, ESP8266EX can be applied to any microcontroller design as a Wi-Fi adaptor through SPI/SDIO or UART interfaces.
ESP8266EX integrates antenna switches, RF balun, power ampli er, low noise receive ampli er, lters and power management modules. The pact design minimizes the PCB size and requires minimal external circuitries.
Besides the Wi-Fi functionalities, ESP8266EX also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor and on-chip SRAM. It can be interfaced with external sensors and other devices through the GPIOs. Software Development Kit (SDK) provides sample codes for various applications.
Espressif Systems’ Smart Connectivity Platform (ESCP) enables sophisticated features including:
- Fast switch between sleep and wakeup mode for energy-ef cient purpose;
- Adaptive radio biasing for low-power operation
- Advance signal processing
- Spur cancellation and RF co-existence mechanisms for mon cellular, Bluetooth, DDR, LVDS, LCD interference mitigation
