USB to UART Controller (Gen 1)

Please visit the Cypress USB to UART Gen 2 (CY7C65213) product page to learn more about our latest part with USB-UART bridge functionality.

The USB to UART Bridge Controller (CY7C64225) is a fully integrated USB to UART controller that provides USB connectivity to devices with a UART interface. The device includes a USB 2.0 Full-Speed Controller, Voltage Regulator and internal EEPROM in a 28-pin SSOP package. These features make the product ideal for upgrading legacy peripherals to USB interface.

USB to UART Bridge Controller is a USB-IF certified, fixed function device that requires no programming from the user. Royalty free Virtual COM Port (VCP) drivers available with it ensure that it appears as a COM port to PC applications.
