Programmable Baud Rate: Supports 115200bps and up to 8Mbps baud rate. 256 byte buffer, supports stages.
Two Asynchronous Ports: Two completely independent asynchronous ports, compatible with 16C550, 16C552, 16C554 and 16C750 and enhanced. Supports 5, 6, or data bits and or stop bits. Supports odd, even, no parity, blank 0, parity, etc.
Support: Support port frame error detection, support interval detection. Supports full duplex and half duplex communication.
Principle: CH382L is a MiniPCIE bus and print port chip that contains two 16C550 or 16C750 compatible asynchronous and an EPP ECP enhanced bi directional parallel port, and can also be extended with up to 24 with the CH438 chip.
Scalability: Thanks to the scalability of the product, it can be expanded according to needs to meet the growing needs of users.
