Glomation announced an ARM9-powered single-board computer (SBC). The new GESBC-9G20 is based on the 400MHz Atmel ARM9 processor AT91SAM9G20, the evolution of the A91SAM9260. The AT91SAM9G20 features 4 times data cache and instruction cache, twice the processor speed and yet consumes less power. The GESBC-9G20 measures 3.75 x 3.5 inches is offered with either 64MB or 128MB of 100MHz SDRAM, plus from 256MB to 1GB of flash storage, all soldered on. Other real-world connectors include 2 USB host ports and single USB device port, a nine-pin connector for one of its three RS-232 ports. The rest of the board’s interfaces, available via pin headers, include two RS-232 ports, one RS-485 port, 10/100 Ethernet, SD/MMC, I2C, and SPI. The GESBC-9G20 also offers up to 40 individually configurable digital I/Os, plus an integrated four-channel, 10-bit A/D converter.
