 After researching different embedded solutions the choice went in favour of the Acme-Systems Netus G20 system, with an ATMEL AT91SAM9G20 400MHz ARM9 CPU (max. 50mW@25°C = 0.125mw/MHz) and 64MB/1.8V BGA SDRAM(532MB/s), to reduce power comsumption and due to the mobile nature of the SDRAM, enabling low power modes, claiming a total of 80mA@5V (0.4W) idle power consumption. Although the Cortex A5 offers more than twice the DMips/W amount, the broader availability, the price and the available amount of documentation on the internet lead to the Netus G20, produced by Acme-Systems, Italy. It was also considered to use an ATMega32 as SKU but the idea was abandoned because a real Linux can offer more features off the shelf and seems a much more flexible solution than to reinvent everything on a uC level. Temperature range: -15 to +70 Celsius degree (°C). After researching different embedded solutions the choice went in favour of the Acme-Systems Netus G20 system, with an ATMEL AT91SAM9G20 400MHz ARM9 CPU (max. 50mW@25°C = 0.125mw/MHz) and 64MB/1.8V BGA SDRAM(532MB/s), to reduce power comsumption and due to the mobile nature of the SDRAM, enabling low power modes, claiming a total of 80mA@5V (0.4W) idle power consumption.
