Kit Overview


The EVBUSB2SEREVBUSB2SER board is part of Freescale's solutions for communication, and provides another way to connect your embedded system via USB. The EVBUSB2SEREVBUSB2SER board is a communication bridge between the USB and serial data, which can be any RS232/RS485 or TTL. The EVBUSB2SEREVBUSB2SER board supports baud rates from 300 through 115200 bps, 8 data bits, odd or even parity, 1 or 2 stop bits, software (xon/xoff) and hardware flow control.


Freescale Ready Play Solutions integrate a certified function to different applications allowing customers to add features while reducing development cost. This simplifies design cycles and enables scalability in applications and systems. The USB2SER is a USB to UART bridge controller on a 5 x 5 mm lead free QFN24. It is a simple low cost solution to enable a USB for an embedded system with a UART port, reducing external component counts. It supports USB 2.0 fullspeed 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 can act as a CDC standard device that eliminates the need for custom drivers for operation when the flow-control is not needed (only an INF file is required).


Key Applications: Medical, Connectivity, Industrial, Motor Control, Universal Serial Bus (USB).
