Universal USB-Interface-Chip CH341A
A solution for your USB project!
USB-RS232-Interface USB-Printer-Interface EPP/MEM Read/Write
Digital I/O I²C-Interface
The CH341 makes it possible to interface different kind of user applications to the PC over USB, without any need of µC controller programming. The Chip can be used as I²C interface to i²C enabled peripheral IC´s. It also offers an 8 bit bi-directional data bus with EPP/MEM protocol, which could be used to interface HD44789 compatible text LCD displays for example. The Chip can also work as USB-RS232 interface, often needed to adapt AVR-applications to USB, where USB powering option is another advantage.
Programming is made easy using an API-DLL, suitable for almost any programming language (Delphi, C, VB ...).
