The **MA78TBA-R** is an industrial-grade motherboard manufactured by **ADLINK Technology**. It is designed using the Micro-ATX form factor and is specifically engineered for high-reliability applications such as industrial automation, medical imaging, and telecommunications. Below is a detailed breakdown of its electronic components and specifications. --- ### 1. Core Architecture & Chipset The board is built around the **AMD 780G (RS780)** Northbridge and the **SB700** Southbridge. This combination was popular for providing robust integrated graphics and high-speed I/O connectivity for its generation. | Component | Specification | | :--- | :--- | | **CPU Socket** | AM2 / AM2+ | | **Processor Support** | AMD Phenom II, Athlon II, Phenom, Athlon 64 X2, and Sempron | | **Bus Speed** | HyperTransport 3.0 (up to 5200 MT/s) | | **Chipset** | AMD 780G + SB700 | ### 2. Memory and Graphics The electronic layout emphasizes stability over overclocking, utilizing standard DDR2 memory slots and an integrated GPU capable of basic hardware acceleration. * **Memory Slots:** 4x 240-pin DIMM sockets. * **Memory Type:** Dual-channel DDR2 800/667 MHz (up to 8GB total). * **Integrated Graphics:** ATI Radeon HD 3200 (DirectX 10 support). * **Video Outputs:** Typically includes VGA and DVI-D. ### 3. Expansion and Connectivity Designed for industrial expansion, the board includes legacy PCI support alongside modern (at the time) PCIe lanes. | Interface Type | Quantity/Speed | | :--- | :--- | | **PCI Express x16** | 1 Slot (for external GPU or high-speed FPGA cards) | | **PCI Express x4** | 1 Slot | | **PCI (32-bit)** | 2 Slots (Standard PCI 2.3) | | **SATA Ports** | 6x SATA II (3.0 Gb/s) with RAID 0, 1, 10 support | | **Ethernet** | Dual Gigabit Ethernet (typically Realtek RTL8111C) | ### 4. Specialized Industrial Features Unlike consumer motherboards, the MA78TBA-R includes components for "always-on" environments: * **Watchdog Timer:** A programmable hardware timer that can reset the system if the software freezes. * **Super I/O:** Uses the **Winbond W83627DHG** chip for hardware monitoring (voltage, fan speed, temperature) and legacy port control. * **Serial Ports:** Multiple RS-232/422/485 headers for connecting to PLC controllers and industrial machinery. * **Longevity:** Components are selected for long-term supply life cycles (7+ years). --- ### 5. Technical Summary Table | Feature | Details | | :--- | :--- | | **Form Factor** | Micro-ATX (244mm x 244mm) | | **Power Connector** | 24-pin ATX + 4-pin 12V | | **USB** | 12x USB 2.0 (6 on back panel, 6 via headers) | | **Audio** | Realtek ALC888 7.1 Channel High Definition Audio | | **Operating Temp** | 0°C to 60°C (Standard Industrial range) |
