The robot vacuum cleaner in your hands, the smart speaker on your shelf, and even the CarPlay box in your car — the Wi‑Fi chip responsible for connecting all of them very likely comes from the same family: Realtek Ameba!

As the mass-production choice of over 70% of the world's top home appliance brands, the Ameba Wi-Fi SoC has passed extremely stringent supply chain validation.

It is not a single chip, but a complete family ranging from 2.4GHz entry-level solutions to dual-core Linux high-performance platforms.

High Performance: IoT Chips That Run Linux

RTL8730E: The Performance Ceiling

When your product needs to run a full Linux system, this is the one!

The RTL8730E is Ameba's application processor-class product, featuring a tri-core heterogeneous architecture designed to handle high-compute scenarios such as real-time video processing, complex protocol stacks, and multi-process concurrency. It integrates dual-band Wi-Fi 6, MIPI display, and BLE Audio — consolidating what would otherwise require multiple chips into a single SoC. With its Google Cast and WiSA certifications, customers can join the Google Smart Home and WiSA wireless audio ecosystems without additional certification.

Tri-core heterogeneous architecture: Dual Cortex-A32 + DDR handles high-compute tasks; Real-M300 (M55-compatible) network processor is dedicated to Wi-Fi/Bluetooth protocol stacks; Real-M200 (M23-compatible) low-power processor is dedicated to standby and wake-up

Mainstream Series: From Smart Home to Industrial Energy Storage

This is the widest-coverage "super corps" in the Ameba family, built around stability, longevity, and high cost-effectiveness.

RTL8721F: The All-Around Display Expert

The current flagship model in the mainstream series, offering the most complete interface set.

Features a built-in LCD Display Controller (LCDC) for direct driving of displays in industrial HMI, smart home, and other applications. Dual CAN bus, 8-channel ADC, and I2S audio interface are all integrated, with WoWLAN ultra-low-power standby. Also supports Wi-Fi Card Mode to function as a standalone Wi-Fi module connected to another host processor, with measured throughput exceeding 80 Mbps; and 5GHz wireless audio transmission capability.

RTL8720E / RTL8710E: The Wi-Fi 6 Twin Stars

The two highest-frequency processors in the mainstream series — dual-core 400MHz, with the RTL8720E boasting 768KB SRAM ahead of its class. Wi-Fi 6 OFDMA supports high-density concurrent scenarios, and the wide-temperature industrial-grade design (on select models) suits outdoor applications such as photovoltaic inverters and energy storage controllers; the QFN48 6×6mm package also accommodates space-constrained compact designs.

RTL8720F: The Cost-Effective Choice

The most affordable option in the Wi-Fi 6 lineup. In a smaller package at a lower price, it retains full Wi-Fi 6 connectivity and R-Mesh networking support, with an industrial wide-temperature range of −40~105°C across the entire product line. For projects with focused functionality requirements and cost sensitivity, it is the more economical choice.

RTL8721Dx: The Dual-Band Veteran, Best Choice for Battery-Powered Devices

The addition of the 5GHz band effectively avoids 2.4GHz channel interference, and combined with WoWLAN ultra-low-power standby, it provides a dual guarantee of stable connectivity and extended battery life for battery-powered devices.

DSP Series: Audio Processing Built into Hardware

Designed for audio scenarios, the DSP series integrates a HiFi5 hardware audio processor on-chip, independently handling everything from voice wake-up and noise reduction to multi-channel audio decoding and playback — all locally, even offline.

RTL8713E / RTL8726E: Powered by HiFi5

Both models feature a tri-core heterogeneous architecture (Arm Cortex-M + RISC-V + HiFi5 DSP), delivering complete audio processing capabilities — the HiFi5 DSP specializes in noise reduction, echo cancellation, and audio enhancement algorithms, while dual I2S + dual DMIC + built-in audio codec cover all audio input and output needs.

Pro Vision Series: RTL8735B

In an ultra-compact 10×10mm package, it integrates ISP, NPU, and Wi-Fi/Bluetooth. With 0.4TOPS of compute power supporting local inference of mainstream AI vision models, there is no need to rely on the cloud — lower latency, less bandwidth.

The Foundation: Ameba's Common DNA

Each model has its own strengths, but across connectivity, security, and architectural design, the Ameba series shares several common capabilities present in multiple models:

Security: Integrates Arm TrustZone, AES/SHA hardware encryption engine, secure boot, OTP secure storage, and PSA Level 2 certification, meeting mainstream IoT security compliance requirements.
R-Mesh Networking: Natively integrates Realtek's proprietary R-Mesh protocol, extending Wi-Fi coverage through multi-node relay, enabling large-scale network coverage at low cost in complex scenarios such as solar power plants and large factory floors.
Ultra-Low Power: Mainstream series WoWLAN standby current below 100μA, maintaining Wi-Fi online connectivity while significantly extending battery life.
Wi-Fi CSI Wireless Sensing: Supports Channel State Information technology, enabling human presence detection, indoor positioning, gesture recognition, and behavior analysis — no camera required.

Unified Development Ecosystem

The Ameba series shares a unified development ecosystem with full resources available throughout:

Multi-OS Support: FreeRTOS, Linux, Zephyr, Arduino, and NuttX, covering all major development frameworks.
Matter Full-Series Support: All 9 chips have completed Matter protocol integration, enabling connection to major smart home platforms such as Apple HomeKit, Google Home, and Amazon Alexa — no need to build a protocol stack from scratch.
One-Stop Resource Platform: Documentation center, video center, case center, news center, and developer forum — from beginner tutorials to mass-production references, from API queries to peer discussions, fully supported throughout development.

Nine chips, one family, covering the complete IoT spectrum from ultra-low-power MCU solutions to Linux application processors!
