USB-Serial Bridge Controllers feature touch sensing and battery-charge detection

Cypress Semiconductor has added a new family of USB-Serial bridge controllers CY7C6521x providing dual-configurable serial channels for UART/SPI/I2C communication along with its CapSense capacitive touch-sensing technology. Cypress provides proprietary drivers to support multiple operating systems. The family features battery-charge detection compliant to Version 1.2 of the USB-Implementers Forum (USB-IF) Battery Charging specification. These USB-Serial controllers consume only 5 uA in standby current.

The new family includes three devices, all of which are certified by the USB-IF. The CY7C65211 and CY7C65215 offer single- and dual-configurable serial channels, respectively, with each capable of UART, I2C, and SPI communication. The CY7C65213 provides a low power USB-to-UART bridge controller. The new controllers target a wide range of applications, including medical equipment, industrial equipment, point-of-sales terminals, USB-to-UART and RS232 cables, gaming systems, and test and measurement equipment.

“With their configurability, touch-sensing and battery-charging compliance, our USB-Serial bridge controllers deliver a combination of features and performance that no competitive offerings can match,” said Badri Kothandaraman, Executive Vice President of the Data Communications Division at Cypress. “The USB-Serial bridge controllers enable our customers to leverage the overall market trend towards Windows 8 and Android operating systems by providing proprietary drivers that works seamlessly with multiple operating systems – Windows, Mac, Android and Linux.”

Cypress provides a software configuration utility for Windows that enables customers to select from multiple serial interfaces and features to create customized designs. This utility also assists customers in modifying various parameters, such as vendor and product IDs, string descriptors, and GPIO configurations, via the USB interface. USB-Serial integrates programmable memory used to store these configuration details. The utility, drivers, and application programming interfaces (APIs) provided by Cypress makes it very easy for customers to develop complete solutions with shorter design cycles, resulting in quick time-to-market, as per Cypress.

All of the new controllers are in production and available now from Cypress and its authorized distributors. The CY7C65211 is offered in a 24-pin QFN package, while the CY7C65213 and the CY7C65215 are packaged in 32-pin QFNs.
