ASIX MCS9900CV-AA

Product Info

MCS9900 is a single lane multifunction PCI express to I/O controller. It supports two modes of operations which are selectable through device mode select pins. Mode1 supports four serial ports and GPIO, Mode2 supports two serial ports, one parallel port and GPIO. MCS9900 also provides an option for peripheral expansion through proprietary Cascade interface. The generic cascade interface allows interconnection with similar chips like MCS9900, MCS9904, MCS9901CV-CC & MCS9922 for port expansion. 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 MCS9900 device options through an external EEPROM.
