Faced with increasingly complex IoT application requirements, developers often have to stack multiple chips together. Is it possible for a single SoC to simultaneously deliver application-level compute power, stable connectivity, and rich peripherals?

The Realtek PKE8730EAH-VD3-F32 Evaluation Kit puts it all on one board, and is now available for purchase. Built primarily for FreeRTOS development, this platform integrates a powerful compute core (dual-core Cortex-A32, 1.2GHz), dual-band Wi-Fi 6, Bluetooth Dual-Mode, a full-featured audio matrix, and a MIPI display interface on a single piece of hardware, turning the vision of "running the full feature set on one SoC" into reality.

Building on this hardware, the RTOS SDK natively integrates the LVGL graphics framework and Smart Voice speech algorithms, providing a validation environment—ready from the physical link all the way up to the software algorithms—for high-performance, multimodal human-machine interaction terminals.

🔈Realtek will soon launch an RTL8730E evaluation board in the same series, equipped with 256MB of high-speed DDR and offering a complete Linux solution with BSP support to unlock more complex applications and software ecosystems (graphics/multimedia frameworks, etc.). Stay tuned!

01 Product Overview

The core strength of the PKE8730EAH-VD3-F32 lies in its high level of integration: developers can achieve, with a single SoC, functionality that previously required a "multi-chip combination." The platform lets you validate the compute power your product needs while advancing connectivity and peripheral evaluation in one pass. And with its high-frequency dual-core synergy, it effortlessly handles complex audio codecs, speech recognition, and large-screen display.

Applicable Scenarios

Well suited for comprehensive projects involving audio capture/playback, stable Wi‑Fi/BT connectivity, and display interaction, helping products strike the best balance between performance and cost while maintaining high integration.

Success Stories

Customers have already built products on the RTL8730E platform such as children's story machines, e-badges, AI toys, smart control panels (86-box wall panels), wireless home theater systems, smart speakers, and more. These product categories place a premium on the boundary of what "a single chip running the entire pipeline" can achieve (connectivity, audio, and display/interaction can all be validated directly on the same hardware), and the Cortex‑A32's ample compute headroom also makes it easy to layer on more complex interaction logic and networking features on the same platform down the road.

02 Core Specifications

Within a palm-sized footprint (85×56mm), the PKE8730EAH-VD3-F32 maps everything from the "compute core" to the "interaction pipeline." The onboard layout is easy to grasp at a glance:

Beyond the intuitive interface layout, the following core specifications reveal more substantive performance details:

Processor/Compute: Integrates a dual-core Cortex-A32 (1.2GHz) application core, a network processing core (Cortex-M55 ISA compatible, 333MHz), and a low-power core (40MHz)
Full-Featured Audio Suite: Onboard 4×AMIC + 2×DMIC interfaces, with a 3.5mm headphone jack and speaker connector, covering the complete pipeline from audio capture to output
High-Definition Interaction Interface: Native MIPI DSI interface, supporting screen evaluation up to 1024×768@60fps and I2C touch
Independent Antenna Design: Dual-band Wi-Fi 6 and Bluetooth Dual-Mode with physically isolated antennas; choose between an onboard PCB antenna or an external IPEX antenna connector
Storage & Expansion: Onboard 16MB Flash + 8MB PSRAM, supports Micro SD card and USB 2.0 (Host/Device), with reserved GPIO/I2C/SPI/PWM expansion headers

03 Quick Start

Get the Documentation & Tools: EVB User Guide, FreeRTOS SDK documentation, the flashing tool (Image Tool); also install the serial port driver and a serial terminal tool.

Power On: Connect to a PC via the onboard Type-C port; a serial terminal tool lets you watch the system self-test log over LOG-UART in real time.

Flash the Firmware: Use the official Image Tool to flash the firmware. Alternatively, developers can use the Online Flashing Tool (aiot.realmcu.com) to flash the default firmware directly—no development environment required—for manual ATCMD testing and evaluation.
