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-

DOIT.AM®ESP-F1 User Manual

APSD), module can close Wi-Fi Modem and stop CPU to save power. For example, at DTIM3, keep up
sleeping at 300ms, it would receive the Beacon package from AP after each 3ms, then the whole average
current is about 0.9mA.
③Deep-Sleep mode is applied to the case that Wi-Fi is not necessary to connect all the time, just send
a data packet after a long time (e.g., transmit one temperate data each 100s) . it just need 0.3s-1s to
connect AP after each 300s, and the whole average current is much smaller 1mA.

10. Peripheral Line Suggestion
Wi-Fi module is already integrated into high-speed GPIO and Peripheral interface, which may be
generated the switch noise. If there is a high request for the power consumption and EMI characteristics,
it is suggested to connect a serial 10~100 ohm resistance, which can suppress overshoot when switching
power supply, and can smooth signal. At the same time, it also can, to a certain extent, prevent
electrostatic discharge (ESD).
