ASIX MCS9901CV-CC

Product Info

MCS9901CV-CC is a single lane multifunction PCI express to I/O controller. It supports two serial ports, one parallel port and six GPIO's. MCS9901CV-CC also provides an option for peripheral expansion through proprietary Cascade interface. The generic cascade interface allows interconnecting with similar chips like MCS9900, MCS9950 to expand the peripheral ports. The serial ports are compatible with RS232, RS422 & RS485 standards and supports throughput from 50bps to 16Mbps. Parallel Port is compatible with IEEE 1284 and supports Nibble, Byte, SPP, ECP, and EPP modes. All the GPIO pins are programmable and can be used as Input or Output. An I²C interface is provided to configure MCS9901CV-CC device options through an external EEPROM.
