ESP32-S0WD

RF Transceiver ICS Overview

The ESP32-S0WD is a single-core, 32-bit MCU and 2.4 GHz Wi-Fi & Bluetooth/BLE System-on-Chip (SoC) manufactured by Espressif Systems. It integrates all peripherals found in its dual-core counterpart within a compact QFN48-pin package measuring 5x5 mm. The device operates at a maximum frequency of 160 MHz with a minimum supply voltage of 2.3 V and a maximum of 3.6 V. It supports data rates up to 150 Mbps and delivers an output power of 20 dBm with a sensitivity of -97 dBm. Power consumption includes receive currents between 95 mA and 100 mA, and transmission current of 240 mA.

RF Transceiver ICS Feature Summary

• Integrates single-core 32-bit MCU with full peripheral set of dual-core variants
• Combines 2.4 GHz Wi-Fi and Bluetooth/BLE capabilities in one chip
• Compact QFN48-pin surface mount package design

RF Transceiver ICS Applications

• IoT devices requiring combined Wi-Fi and Bluetooth connectivity
• Smart home appliances with limited space constraints
• Wearable electronics utilizing BLE features

RF Transceiver ICS Procurement Notes

Verify component status as the ESP32-S0WD is listed as obsolete or end-of-life by major distributors. Confirm availability through authorized channels or recommended substitutes such as the ESP32-D0WD-V3. Ensure compatibility with existing designs before sourcing, as stock levels are typically not maintained for discontinued parts.

RF Transceiver ICS Selection Notes

Select this component when a single-core solution suffices for application processing requirements while maintaining full wireless feature sets. Consider the 160 MHz operating frequency against dual-core alternatives if computational load is low. Verify package compatibility with PCB footprints designed for the 48-pin QFN format.

RF Transceiver ICS Part Context

The ESP32-S0WD belongs to the ESP32 family of RF SoCs, serving as the single-core variant alongside dual-core models like the ESP32-D0WD. It shares architectural similarities with other ESP32 chips but reduces core count to lower cost and power consumption while retaining identical peripheral interfaces and wireless standards support.

RF Transceiver ICS Replacement Considerations

The ESP32-D0WD-V3 is identified as a manufacturer-recommended substitute. Note that the replacement offers dual-core processing capability compared to the single-core original.
