## Overview: Advantech ROM-5722CD-RFA1E The **ROM-5722CD-RFA1E** is a Computer-on-Module (CoM) or System-on-Module (SoM) designed by Advantech. It is based on the **SMARC 2.1 (Smart Mobility ARChitecture)** standard and is powered by the **NXP i.MX 8M Plus** processor family. --- ### Core Specifications | Component | Specification | | :--- | :--- | | **Processor** | NXP i.MX 8M Plus Quad (4x Cortex-A53 + 1x Cortex-M7) | | **Memory (RAM)** | 2GB LPDDR4 | | **Storage (eMMC)** | 16GB eMMC | | **NPU (AI)** | 2.3 TOPS Neural Processing Unit | | **Graphics** | GC7000UL (3D) + GC520L (2D) | | **Standard** | SMARC 2.1 | | **Operating Temp** | 0 ~ 60°C (Commercial Grade) | --- ### Key Electronic Subsystems #### 1. Processing Unit (SoC) The heart of the module is the **i.MX 8M Plus**. This SoC is specialized for edge computing and machine learning. - **Cortex-A53:** Handles the high-level operating system (Linux/Android). - **Cortex-M7:** Handles real-time tasks and low-power monitoring. - **NPU:** Specifically designed to accelerate deep learning frameworks (TensorFlow Lite, etc.). #### 2. Connectivity & I/O Interfaces The module routes high-speed signals through the 314-pin SMARC connector: - **Networking:** Dual Gigabit Ethernet (one supports TSN - Time Sensitive Networking). - **USB:** 1x USB 3.0, 2x USB 2.0. - **PCIe:** 1x PCIe Gen 3 lane for expansion (e.g., Wi-Fi or NVMe). - **Display:** Dual channel LVDS or MIPI-DSI, and HDMI 2.0. - **Camera:** 2x MIPI-CSI (4-lane) interfaces. #### 3. Power Management The module utilizes a dedicated **PMIC (Power Management IC)** to regulate voltages for the CPU core, DDR memory, and I/O rails. It typically requires a single **5V DC** input from the carrier board. #### 4. Signal Integrity features - **On-board Flash:** 8MB QSPI Flash for bootloader storage. - **Watchdog Timer:** Prevents system hangs in industrial environments. - **Hardware Encryption:** Includes a secure element or TrustZone support for encrypted booting. --- ### Typical Applications * **AIoT Edge Gateways:** Processing sensor data locally using the NPU. * **Industrial Vision:** Dual camera inputs allow for stereo vision or inspection tasks. * **Human Machine Interface (HMI):** Driving high-resolution touchscreens in medical or factory settings.
