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-D0WD-V3, ESP32-D0WDQ6-V3, ESP32-D0WD, ESP32-D0WDQ6,

ESP32-D2WD, ESP32-S0WD, and ESP32-U4WDH, among which, ESP32-D0WD-V3, ESP32-D0WDQ6-V3, and

ESP32-U4WDH are based on ECO V3 wafer.

For details on part numbers and ordering information, please refer to Section 7.

For details on ECO V3 instructions, please refer to ESP32 ECO V3 User Guide.

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.
