1. Introduction

The WiFi module ESP-F1 is manufactured by using a high-performance chip ESP8266EX. This small

chip is encapsulated an enhanced Tensilica’sL106 diamond series 32-bit kennel CPU with a SRAM.

Thus, ESP8266 has the complete function Wi-Fi function; it not only can be applied independently, but

can be used as a slaver working with other host CPU. When ESP8266 is applied as a slaver, it can start

from the onboard Flash. The built-in high-speed buffer is not only benefit to improve the system

performance, but optimize the store system. In addition, ESP8266 can be used as Wi-Fi adapter by

SPI/SDIO or I2C/UART interface, when it is applied to other MCU design.

The ESP-F1 module supports the standard IEEE802.11 b/g/n/e/i protocol and the complete TCP/IP

protocol stack. User can use it to add the WiFi function for the installed devices, and also can be viewed

as a independent network controller. Anyway, ESP-F module provides many probabilities with the best

price.

Note

①: Modem-Sleep mode can be used for the case that CPU is always working, e.g., PWM or I2S etc. If

WiFi is connected and no data is to transmitted, in this case, WiFi modem can be closed to save power

energy. For example, if at DTIM3 status, keep asleep at 300ms, Then, the module can wake up to receive

the Beacon package within 3ms and the current being 15mA.

②: Light-Sleep mode can used for the case that CUP can stop the application temporally, e.g., Wi-Fi

Switch . If Wi-Fi is connected and there is no data packet to transmitted, by the 802.11 standard (e.g., U-
