Infineon CY7C65213-32LTXIT, USB Controller, 12Mbps, USB 2.0, 1.71 to 5.5 V, 32-Pin QFN

The Infineon USB Controller 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. It includes a USB 2.0 full speed controller, a UART transceiver, an internal regulator, an internal oscillator and a 512 byte flash in 32 pin QFN 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.

Data rates up to 3 Mbps
