Data Sheet

1 OVERVIEW

1. Overview

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

technology. It is designed and optimized for the best power performance, RF performance, robustness, versatility,

features and reliability, for a wide variety of applications, and different power profiles.

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 has many features

of the state-of-the-art low power chips, including fine resolution clock gating, 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 power of the power amplifier is also adjustable to achieve 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 the most integrated solution for Wi-Fi + Bluetooth applications in the industry with less than 10 external

components. ESP32 integrates the 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, and also integrates advanced calibration

circuitries that allow the solution to dynamically adjust itself to remove external circuit imperfections or adjust to

changes in external conditions.

As such, the mass production of ESP32 solutions does not require expensive and specialized Wi-Fi test equip-

ment.
