The **ROM-5722WD-RFA1E** is a high-performance SMARC (Smart Mobility ARChitecture) 2.1 module manufactured by **Advantech**. It is built on the NXP i.MX 8M Plus platform, designed specifically for AI-at-the-edge, machine learning, and industrial multimedia applications. --- ## 1. Core Technical Specifications The following table highlights the primary electronic components and processing capabilities of the module. | Feature | Specification | | :--- | :--- | | **Processor** | NXP i.MX 8M Plus Quad (4x Arm Cortex-A53 @ 1.8 GHz) | | **Co-Processor** | Arm Cortex-M7 (800 MHz) for real-time processing | | **NPU (AI Accelerator)** | Integrated Neural Processing Unit (up to 2.3 TOPS) | | **Memory (RAM)** | 4GB LPDDR4 (Industrial Grade) | | **Storage (eMMC)** | 32GB eMMC (On-board flash) | | **Form Factor** | SMARC 2.1 Standard (82 x 50 mm) | | **Operating Temp** | -40 ~ 85°C (Wide Temperature/Industrial Grade) | --- ## 2. Key Electronic Functional Blocks ### A. AI and Vision Processing The standout electronic component is the **Integrated NPU**. This allows the module to handle complex machine learning tasks (like object detection and speech recognition) locally without relying on a cloud connection. It also features a Dual Image Signal Processor (ISP) for high-quality camera input. ### B. Graphics and Multimedia The module integrates a Vivante GC7000UL GPU, supporting: * **Video Decode:** 1080p60 HEVC/H.265, H.264, VP9, VP8. * **Video Encode:** 1080p60 H.265, H.264. * **Display Interfaces:** Dual-channel LVDS (or MIPI-DSI) and HDMI 2.0. ### C. Connectivity and I/O As a SMARC module, it routes signals through a 314-pin edge connector: * **Networking:** Dual Gigabit Ethernet (one with TSN - Time Sensitive Networking support). * **USB:** 1x USB 3.0, 2x USB 2.0. * **PCIe:** 1x PCIe Gen 3 slot for expansion (e.g., Wi-Fi or NVMe). * **Industrial I/O:** CAN-FD, UART, I2C, SPI, and GPIO. --- ## 3. Part Number Decoder: ROM-5722WD-RFA1E Advantech part numbers are structured to define specific hardware configurations: * **ROM-5722:** The base model series (i.MX 8M Plus SMARC). * **W:** Wide Temperature support (-40 to 85°C). * **D:** Dual/Quad Core configuration (Quad in this specific variant). * **RFA1E:** Revision code and specific packaging/firmware version. --- ## 4. Power Requirements The module is designed for low power consumption, typically drawing between **4W to 6W** depending on the NPU load. It requires a standard **5V DC** input via the SMARC carrier board.
