1. Single-chip Hi-Speed USB 2.0 to Serial data transfer interface;
2. Fully Compliant with USB 2.0 specification(Hi-Speed Mode);
3. Implements USB protocol composite device:
*Communication Device Class (CDC) -Abstract Control Model (ACM) subclass for virtual COM port;
*USB Mass Storage Device Class (MSC) for file storage;
4. Driver Support:
*Built-in USB CDC-ACM class inbox driver in Windows1, Mac, Android, and Linux;
*Prolific CDC-ACM royalty-free driver for chip full-feature support (Virtual COM Port, GPIO control, faster baud rate, etc.);
5. On-chip 24KB embedded Flash
*For writing and storing custom device startup configuration like USB VID/PID, Serial Number, Product String, and other device configurations;
*For storing Windows INF/Readme files;
6. Embedded Flash or external SPI Flash can emulate as USB mass storage drive to access stored read-only user files;
7. Four General-Purpose I/O (GPIO) pins for user-defined application;
8. Supports USB to RS232 Serial UART interface:
*Full-duplex transmitter and receiver (TXand RX);
*Six MODEM control pins (RTS, CTS, DTR, DSR, DCD, and RI);
*5, 6, 7, or 8 data bits;
*Odd, Even, Mark, Space, or None parity mode;
*One, one and a half, or two stop bits;
* Parity error, frame error, and serial break detection;
*Programmable baud rate from 75bps to12Mbps;
*External RS232 driver power-down control.
