The Guild to TI Cortex-A8 AM335X Development Board
Highlights:
- ◆ Ti AM335X series processor, up to 800MHz high-speed ARM Cortex-A8 core;
- ◆ 512MB DDR3, makes it possible to run more code programs;
- ◆ 256MB NandFlash;
- ◆ 2 lane 10M/100M/1000M Ethernet port;
- ◆ The core board has a single 5V power supply, and adopts TI's own MPU management chip to output all the voltages required by the core board;
- ◆ The bottom plate has an independent RTC, which is accurate when it is traveled;
- ◆ Ultra-low power consumption, single board power 0.5W;
- ◆ LCD display performance: support maximum resolution 2048x2048, while supporting VGA output, with 3D graphics accelerator;
- ◆ Perfect support for Windows Embedded Compact 7Linux 3.2Android 4 embedded operating system.
The advantages of the AM335x:
First: The device is the most affordable Cortex A8 processing chip, which is a crucial and even decisive factor for the Chinese market.
Second: The most publicly available chip in TI's history.
Third: An industrial control MCU with the clearest product positioning.
Fourth: The only MCU that integrates 2 MACCs.
Fifth: Currently the only support for Android 4.0, and supports 3 operating systems Linux, Android, WinCE at the same time. It has been widely used in industrial control, medical electronics, energy conservation, and environmental protection, intelligent transportation, energy and energy saving, power systems, communication systems, textile industry, CNC industry, automotive electronics, industrial touch screen control systems, robot vision, media processing wireless applications, digital home appliances, on-board equipment, communication equipment, network terminals, and other environmentally harsh occasions.
