Realtek Ameba IoT SoC Series - Leading Wi-Fi & Bluetooth SoC Solutions

Realtek IoT delivers industry-leading Wi-Fi 6 and Bluetooth 5.3 SoC solutions through the Ameba series (RTL8730E, RTL8720E, RTL8721F). Our Realtek IoT chips integrate high-performance Arm® Cortex®-A32/M, RISC-V and HiFi DSP, supporting dual-band Wi-Fi 6 (802.11ax), Bluetooth 5.3 dual-mode, Matter protocol, and enterprise-grade TrustZone security. With native support for Zephyr RTOS and Arduino development environments, Realtek IoT solutions are ideal for smart home, industrial automation, Edge AI, and multimedia applications, offering ultra-low power consumption, LE Audio with Auracast™, and rich peripheral interfaces including MIPI-DSI, USB 2.0, Ethernet, SDIO, UART, I2C, SPI and so on.

Realtek Ameba IoT SoC series offers unmatched development flexibility for MCU and embedded system designers. Our product portfolio spans four distinct series: Mainstream Series for ultra-low power smart control, DSP Series for professional audio processing, High-Performance Series with Linux support for advanced applications, and Pro Series for intelligent vision and camera solutions. Each series combines ultra-low power consumption, real-time processing, advanced digital signal processing, and robust hardware security.

Beyond standard IoT features like peripheral interfaces (SPI, I2C, UART, USB), secure boot, and AES/SHA hardware encryption, Realtek Ameba SoCs include specialized capabilities: R-MESH networking for extended coverage, Wi-Fi CSI sensing for environmental awareness, HMI touch displays for smart interfaces, audio ADC/DAC for sound processing, SDIO/SD/eMMC host for storage expansion, Ethernet for wired connectivity, and Controller Area Network (CAN) for industrial and automotive applications.
