The CY7C6521x family provides dual-configurable serial channels for UART/SPI/I 2C communication along with CapSense capacitive touch-sensing technology, enabling flexible design of human interface solutions. Cypress provides proprietary drivers to support multiple operating systems, adding to the design flexibility of the controllers. The family is also the first to integrate efficient battery-charge detection compliant to Version 1.2 of the USB-Implementers Forum (USB-IF) Battery Charging specification. Additionally, the USB-Serial controllers boast the industry’s lowest power consumption of 5 µA (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, I 2C, and SPI communication. The CY7C65213 provides a low power USB-to-UART bridge controller. The new controllers target applications including medical equipment, industrial equipment, point-of-sales terminals, USB-to-UART and RS232 cables, gaming systems, and test and measurement equipment.
Cypress provides a software configuration utility for Windows that enables customers to select from multiple serial interfaces and features. 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.
