Illinois chip designer Grid Connect has developed a ARM-based System on a Chip with integrated Gigabit Ethernet for the low cost embedded marketplace costing just $10 .
The gridARM is designed for low cost products that require a fast Ethernet connection. As most IT networks, PCs and laptops are all gigabit Ethernet, it only makes sense to have all your devices on the network to be as fast as possible and the gridARM is designed to be the main processor in the system.
The gridARM is available in volume today, manufactured by Atmel. The development kit includes an evaluation board, cables, JTAG emulator, power supply and a complete set of development tools including a royalty free real-time operating system, TCP/IP v4/6 library, web server, telnet and example tunneling software.
It is available in two packages – 225 pin BGA and 208 pin QFP. The gridARM chip includes an ARM7TDMI core, 10/100/1000 Ethernet MAC, CAN controller, up to 3 serial ports, I2C, SPI, on chip SRAM, USB device, A/D converters, and interfaces for SDRAM, Flash, Compact Flash, external SRAM, and NAND flash.
The gridARM is Grid Connect’s third ASIC in the family. The LX and EX ASICs have been around since the early 2000 and are used by thousands of customers in commercial and industrial applications.
