ESP8684H4X

Overview

The ESP8684H4X is a cost-optimized, single-core RISC-V SoC designed for secure 2.4 GHz Wi-Fi and Bluetooth LE 5.0 connectivity. It integrates 4 MB of internal flash and 272 KB of SRAM within a compact 4x4mm QFN package, operating across an extended temperature range of -40 C to +105 C. This module is specifically engineered for simple IoT applications that require high output power and robust security features like secure boot and flash encryption.

Why Choose This Part

It offers an impressive 21.5 dBm Wi-Fi output power and up to 20 dBm for Bluetooth LE, ensuring long-range connectivity without external power amplifiers. The RISC-V core provides efficient processing at 120 MHz while maintaining low power consumption in deep-sleep modes down to 5 uA.

Applications

Getting Started

Developers can use the Espressif IoT Development Framework (ESP-IDF) or the Arduino core for ESP32-C2/ESP8684. Flash programming is supported via UART using the internal Flash In-Circuit Programming (ICP) mechanism and the esptool.py utility.

Also Consider

ESP32-C3-WROOM-02 Espressif Systems - Provides a more powerful RISC-V core with 400 KB SRAM for applications requiring larger memory buffers.

ESP8266EX Espressif Systems - A legacy cost-effective alternative for Wi-Fi only applications that do not require Bluetooth LE.

nRF52832 nRFNordic Semiconductor - Lower power consumption for Bluetooth-only applications needing an ARM Cortex-M4F core.
