ESP8266-EVB-BAT

Description

Espressif Systems Intelligent Connection Platform (ESCP) is a group of high-performance, highly integrated products Wireless SOC, designed for designers of mobile platforms with limited space and power. It provides Unparalleled ability to embed WiFi functions into other systems or run independently Application, the lowest cost, and the smallest footprint. ESP8266-EVB-BAT provides a complete, self-contained WiFi network solution; it can be used to host The application or uninstall the WiFi network function from another application processor. After ESP8266-EVB-BAT hosts the application, it will boot directly from the external flash memory. Already integrated Cache in such applications to improve system performance. In addition, as a WiFi adapter, wireless Internet access can be added to any microcontroller-based design through a simple connection (SPI/SDIO or I2C/UART interface). ESP8266-EVB-BAT is one of the most integrated WiFi chips in the industry; it integrates an antenna Switch, RF balun, power amplifier, low noise receiving amplifier, filter, power management module, It requires minimal external circuits, and the entire solution including front-end modules is designed Occupies the smallest PCB area. ESP8266-EVB-BAT also integrates an enhanced version of Tensilica L106 Diamond series 32-bit processors, In addition to WiFi function, it also has on-chip SRAM. ESP8266EX is usually integrated with external Sensors and other specialized devices via its GPIO; sample code for such applications Provided in the software development kit (SDK).

Ultra Low Power Technology

ESP8266-EVB-BAT has been designed for mobile, wearable electronics and Internet of Things applications with the aim of achieving the lowest power consumption with a combination of several proprietary techniques. The power saving architecture operates mainly in 3 modes: active mode, sleep mode and deep sleep mode. By using advance power management techniques and logic to power-down functions not required and to control switching between sleep and active modes, ESP8266-EVB-BAT consumes about than 60uA in deep sleep mode (with RTC clock still running) and less than 1.0mA (DTIM=3) or less than 0.5mA (DTIM=10) to stay connected to the access point. When in sleep mode, only the calibrated real-time clock and watchdog remains active. The real-time clock can be programmed to wake up the ESP8266-EVB-BAT at any required interval. The ESP8266-EVB-BAT can be programmed to wake up when a specified condition is detected. This minimal wake-up time feature of the ESP8266-EVB-BAT can be utilized by mobile device SOCs, allowing them to remain in the low-power standby mode until WiFi is needed. In order to satisfy the power demand of mobile and wearable electronics, ESP8266-EVB-BAT can be programmed to reduce the output power of the PA to fit various application profiles, by trading off range for power consumption.
