USB to Serial Bridge - a Ready Play® Solution

USB2SER
No Longer Manufactured
  • This page contains information on a product that is not recommended for new designs.

Our new Ready Play® solutions integrate certified functionality to different applications, allowing customers to add features while reducing development cost, simplifying design cycles and enabling scalability in applications and systems. We are developing a complete range of Ready Play solutions. The first product in our Ready Play solutions series is a USB to Serial bridge (USB2SER).

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).
