ESP8266 System Description

2022-12-08
●This document provides technical description of ESP8266 series products including ESP8266EX, ESP-LAUNCHER, and ESP-WROOM
●Overview:
■Espressif’s ESP8266EX delivers highly integrated Wi-Fi SoC solution to meet the continuous demands for efficient power usage, compact design and reliable performance in the industry.
■With the complete and self-contained Wi-Fi networking capabilities, It can perform as either a standalone application or the slave to a host MCU. When ESP8266EX hosts the application, it promptly boots up from the external flash. The integrated high-speed cache helps to increase the system performance and optimise the system memory. Also, ESP8266EX can be applied to any micro-controller design as a Wi-Fi adaptor through SPI / SDIO or I2C / UART interfaces.
■ESP8266EX integrates antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules. The compact design minimise the PCB size and allows for minimal external circuitry.
■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 include fast switching between sleep and wake-up mode for energy-efficiency purpose, adaptive radio biasing for low-power operation, advance signal processing, spur cancellation and radio co-existence mechanisms for common cellular, Bluetooth, DDR, LVDS, LCD interference mitigation.
