1. Overview

ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC ultra-low-power 40 nm

technology. It is designed to achieve the best power and RF performance, showing robustness, versatility and

reliability in a wide variety of applications and power scenarios.

The ESP32 series of chips includes ESP32-D0WDQ6, ESP32-D0WD, ESP32-D2WD, and ESP32-S0WD. For

details on part numbers and ordering information, please refer to Part Number and Ordering Information.

1.1 Featured Solutions

1.1.1 Ultra-Low-Power Solution

ESP32 is designed for mobile, wearable electronics, and Internet-of-Things (IoT) applications. It features all the

state-of-the-art characteristics of low-power chips, including fine-grained clock gating, multiple power modes, and

dynamic power scaling. For instance, in a low-power IoT sensor hub application scenario, ESP32 is woken up

periodically and only when a specified condition is detected. Low-duty cycle is used to minimize the amount of

energy that the chip expends. The output of the power amplifier is also adjustable, thus contributing to an optimal

trade-off between communication range, data rate and power consumption.

Note:

For more information, refer to Section 3.7 RTC and Low-Power Management.

1.1.2 Complete Integration Solution

ESP32 is a highly-integrated solution for Wi-Fi-and-Bluetooth IoT applications, with around 20 external com-

ponents. ESP32 integrates an antenna switch, RF balun, power amplifier, low-noise receive amplifier, filters,

and power management modules. As such, the entire solution occupies minimal Printed Circuit Board (PCB)

area.

ESP32 uses CMOS for single-chip fully-integrated radio and baseband, while also integrating advanced calibration

circuitries that allow the solution to remove external circuit imperfections or adjust to changes in external condi-

tions. As such, the mass production of ESP32 solutions does not require expensive and specialized Wi-Fi testing

equipment.
