ERTEC 200 (Enhanced Real-time Ethernet Controller)

Product description:

ERTEC 200 Enhanced Real-time Ethernet Controller

ERTEC 200 is an enhanced real-time Ethernet controller for use in PROFINET based automation applications. ERTEC 200 contains an ARM946E-S 32-bit RISC processor, an external memory interface for SDRAM and static memory, a local bus interface, a 2-channel real-time Ethernet switch with integrated PHYs, that saves the external switch, synchronous and asynchronous serial ports and general purpose I/Os. The 2-channel switch architecture makes ERTEC 200 fit perfectly in a PROFINET line topology. ERTEC 200 comes in a compact 304-pin FBGA package. Together with a ready-made IRT-capable PROFINET IO device stack software, that runs under the leading real-time operating systems eCos or VxWorks, ERTEC 200 provides users with an easy, fast and cost-efficient way to certified PROFINET products.
