USB2SER is a USB to UART bridge controller on 5x5mm lead free QFN24. It is a simple low cost solution that enables USB for an embedded system with a UART port, which reduces external components count. It supports USB 2.0 full-speed and TTL RS232 or RS485 UART with options for hardware flow control, software flow control (Xon-Xoff), even or odd parity and stop bits configuration. The USB2SER is fully compliant with the USB 2.0 specification, and it can act as a CDC standard device which eliminates the need for custom drivers for operation when flow-control is not needed (only an INF file is required).
Features
- Single chip USB to UART Data Transfer (RS232 or RS485)
- Certified Full USB 2.0 support - full speed
- UART with programmable custom baud rates from 300bps to 115200bps and hardware flow control (RTC / CTS) or Software Xon/Xoff flow control
- RESUME signal to request a remote wake-up and SUSPEND output to indicate that the device is in Suspended Mode
- Supports 2MHz, 4MHz, 6MHz, 8MHz, 12MHz and 16MHz external crystals with automatic crystal frequency detection
- Configurable USB VID, PID and Device Description strings in internal Flash
- Configurable Password to protect device from additional parameters modifications
- USB2SER comes in a compact 5x5mm Pb free RoHS compliant QFN24
- USB2SER can act as a CDC standard device which eliminates the need for custom drivers for operation when flow-control is not needed (only an INF file is required)
