CY7C652xx EZ-USB™ Serial Bridge Controllers Infineon Technologies CY7C652xx EZ-USB™ Serial Bridge Controllers offer configurable serial channels for UART/I2C/SPI interfaces, with low power consumption in standby mode (5µA). These controllers integrate the industry-leading CAPSENSE™ capacitive-touch sensing technology (for touch-sensitive key switches) and USB-IF Battery Charging specification ver. 1.2 (to detect the source of power on the USB port). These Infineon Technologies controllers are ideal for applications such as portable medical devices (like blood-glucose meters), point-of-sales terminals, Serial Cables (including USB-to-UART and RS232 cables), and many other applications requiring USB connectivity.
