UA9638CD

The UA9638CD is a universal high-speed PC/AT multiport serial chip. It is a five-port device that supports single-chip serial port solutions for PCs, servers, embedded systems and workstations. It is the latest solution for connecting a high performance, feature rich, fast serial peripheral device to the host system.The UA9638CD provides five individually configurable serial ports with each port supporting multiple configurable I/O options with independent clock sources. All five ports can be easily configured to work with a variety of external devices including RS232, RS422 and RS485. The combination of flexibility and performance makes the UA9638CD an ideal choice for building high-speed serial port solutions.The UA9638CD is designed to be used as an interface between the host system, such as a PC or server, and various external serial devices such as printers, modems and other peripherals. The device can be configured to support various I/O options such as standard parallel ports, RS-232, RS-422, or RS-485. The device also supports numerous data rates ranging from 1.5Mbps up to 8.5Mbps.The UA9638CD is also designed to be used to control and monitor multiple serial ports running at different data rates simultaneously. This allows the number of ports to be easily expanded without having to switch chips or design multiple boards.The working principle of the UA9638CD is quite simple. It consists of five independent universal asynchronous receivers and transmitters (UARTs), each of which can be configured to handle a variety of serial protocols, such as RS-232, RS-422, or RS-485. The chip also includes an internal clock source which selects the data rate for each of the UARTs.Once the configuration is set, the UA9638CD will take care of the rest of the serial port communications. It essentially acts as the "traffic cop" between the host system and the external devices.The UA9638CD also allows the host system to control and monitor multiple serial ports running at different data rates. This allows the number of ports to be easily expanded without having to switch chips or design multiple boards.The UA9638CD is an ideal choice for embedded systems requiring multiple serial ports with low power requirements and high reliability. It is a versatile device with numerous configurable options and is relatively easy to integrate into most systems.Overall, the UA9638CD is a highly integrated, high-performance, low-power, and low-cost universal multi-port serial port solution. It is an ideal choice for embedded systems, PCs, and servers, providing a large number of configurable options and is relatively easy to use.
