Content for CY7C65213


CY7C65213/CY7C65213A is a fully integrated USB-to-UART bridge that provides a simple method to upgrade UART-based devices to USB with a minimal number of components. CY7C65213/CY7C65213A includes a USB 2.0 Full-Speed controller, a UART transceiver, an internal regulator, an internal oscillator, and a 512-byte flash in a 32-pin QFN and 28-pin SSOP package. The internal flash is used to store custom-specific USB descriptors and GPIO configuration. This is done in-system using a configuration utility that communicates over the USB interface. Cypress provides royalty-free Virtual COM Port (VCP) device drivers. The drivers allow the device to appear as a COM port in PC applications. All UART signals, including handshaking and control signals, are implemented.
