DESCRIPTION

ERTEC 200 is a powerful communication block for development of industrial Ethernet devices. ERTEC

200 contains a 32-bit RISC processor, an external memory interface with SDRAM and SRAM controller, an LBU interface, a 2-channel real-time Ethernet interface with integrated PHYs, synchronous and

asynchronous serial ports, and general purpose I/Os. Its robust construction, specific automation functions, and openness to the IT world are distinguishing features. The ERTEC 200 is housed in a 304-pin

plastic FBGA package (19 mm × 19 mm).
