Open source hardware is a very fire project, with a raspberry party and Arduino, there is a BB-Black with Ti. These open source hardware ARM boards have been greatly sought after in Chuangkei. More and more chip monographers have begun to design such a hardware and hardware open source board for their own CPU, intended to run the horses in the open source market. In such an environment, ATMEL and EmeBest have launched an official evaluation board based on SAMA5D3 processor, namely SAMA5D3 XPLAINED.
Sama5d3 xplained is an ATMEL currently pushing a processor that uses the ARM Cortex-A5 architecture, the main frequency up to 536MHz. Maybe everyone is used to TI handlers, the main frequency of 1GHz, feels 536MHz too little children, but if compared to ATMEL's products, such as the previous 9G45, the earlier 9263 series only 400MHz and 200MHz, Will understand that the two words "tall" are really not fooling. Therefore, 536MHZ is already greatly progressing for Atmel.
In addition, the series of processors walk is low-power route. According to the official data provided, the series of processors is below 150mW of full-load operation; at low power mode runs below 0.5MW, it is an ideal choice for battery power applications. When SAMA5D3 XPlained is running Linux without any peripheral, the measured power consumption is 1 watt, that is, 5V 200mA.
Sama5d3 XPlained Evaluate board 256MB DDR2 and 256MB of NAND Flash. The whole plate is 12.5 x 7.5 x 2cm, and it is small and exquisite. Moreover, SAMA5D3 XPLAINED uses the design of the 10-layer board. At present, there is a total of 8 layers or 10 layers in the market, and I don't think that the ARM processor of Atmel is mainly for industrial control that requires high stability. The field, so it has always been a relatively high stability resistor screen. However, this situation has changed, and the SAMA5D3 processor adds support for capacitive screens. It can be seen that Atmel slowly adds some sensibility, the Sama5d3 XPlained evaluation board also designs the corresponding interface for this feature. In addition, SAMA5D3 XPlained also led to a Gigabit network port and a two-way dual network port, expanded its application range in the industrial control.
Sama5d3 XPlained also has a killer - completely compatible with Arduino. This means that all hardware modules and applications supported on Arduino can be ported to SAMA5D3 XPLAINED, which increases the playability of the evaluation board. At the same time, online outdoor open source applications can be used to evaluate its hardware on Sama5d3 XPlained, which is convenient for quick start. Based on SAMA5D3 XPLAINED, its main stage should be in navigation equipment, Internet of Things, netbooks, Internet of Things devices, handheld computers, gaming machines, etc.
After playing SAMA5D3 XPLAINED, you can customize the ARM board that suits you product based on the SAMA5D3 processor. Below is an application example of SAMA5D3 in the actual Internet - a thermostat, similar to the air conditioner controller.
The working principle is to detect ambient temperature by SAMA5D3 XPLained external temperature sensor, then display the temperature value on the LCD screen; field temperature control can be implemented by the key to control by GPIO; remote temperature control can pass through external Wi-Fi device The application on the phone is communicating. At the same time, the purpose of transmitting ambient temperature data to air conditioning by using the ZigBee module can be implemented in the temperature control area.
